Subject:       What about ~anim5~ and Imagine?
Date:          Wed, 1 Jun 1994 10:52:41 GMT+2
From: [e-mail]

Lately, I tried to create an animation using ~anim5~ format.
It is built-in in Imagine, but up to now it seems to work wrong.
I played my ~anim5~ format of the animation using DP IV.
The first frame was O.K. but others.....were damaged (colours palette
was not correctly set by Imagine).
Any suggestions?

Subject: Imagine 4 Everybody - The campaign goes on!
Date: Wed, 25 May 94 21:37:27 +0200
From: [e-mail] (Anders Lattermann)

  ********************************************************************
  ****                Imagine 4 everybody!                        ****
  **** Your chance to make your suggestions in the next release!  ****
  ********************************************************************

                         Greetings Imagineers!

Imagine 3.0 is shipping and it's time to evaluate it. See whats there and
whats not and to look forward in what we, the users, want in the next
release.

I thoght of a way to do it, and if you read along, you'll find out how your
ideas can be in the next release. No promises though :-)

In a note from Mike Halvorson some time ago. (Mike is the president of
Impulse), regarding the shipping status of Imagine 3.0 for both the Amiga
and the PC platforms he said: (The message below is in an shorted edited
form)

----------------------------------------------------------------------

TO all Imagine users on Planet Earth as well as all outposts where from time
to time it seems some of you live. 8').  (some not all)

As of today, April 29th  1994  all US and Canada order for Imagine PC and
Amiga are on their way to you.

Now the challenge begins: Imagine has had an interesting history and
exciting future. I have said on this forum many times that it is not the
software that makes great users it is great users that make the software, so
I am depending on each of you to dig and find out what we have done.

I realize that there will be those who try and find the mistakes or bugs
first, thats cool, we want to know what we missed and we more importantly
want to make sure we fix the problems as fast as we can.

Some things were left out, but not for long.  WE have already begun to start
the next rev of the software.  So if you miss something that you felt you
could not live without, hang in there, we know about it and will add these
and more features than you can IMAGINE.

Our success depends on your satisfaction with Imagine, and this is a two way
street.  You need to tell us what you want and we need to do our best to
make it happen.  However we want things in the code as well.  Things that
you never mentioned you wanted or needed.  Try out the deformation tools,
they are so full of cool that they deserve several sleepless nights all unto
themselves, I know I have had a few.

In closing this note, I want to als challenge each of you to see the
positive in what you find, we really dont work well with blatant negative
comments.  Dont get me wrong, we like a good flaming just as much as the
next guy.  But from time to time it gets very personal here on the IML and
we arent much for that kind of backward activity. Impulse is not on some
high mountain in an Ivory Tower.  WE are users just like you, we are lucky
that we get to make some of the products that you use, and we appreciate
your support,.

--------------------------------------------------------------------------

Ok, Impulse wants us to tell them what we want. Let's do it!

If you have ideas and/or find bugs you like to see implemented/fixed in the
next release, send a message about it to me and I'll put a list together
with everybodys messages and after that, mail it out so everybody can read
it and vote which things you find most important. Yes, I said vote!

Why? Because without some statistics Impulse will have a BIG list and no
clue to what we think are the most important things to fix first. I will
collect the votes. Put everything together and see to that the results comes
out on the nets and of course also reaches Impulse.

Why I'm doing this?

Well, I have the time for the moment and I have acces to Internet, Fidonet
and AmigaNet. So we can reach everybody using Imagine. And also because I
came up with the idea for this baby!

How to do it?

First, I want this so easy as possible (I'm lazy ;-). This means only one
bug report/idea per message. But you can of course send as many messages as
you want. I _will_ ignore messages with more than one subject from now on. I
spent 40 minutes in cutting one message up and that was the last one.

I want the header in the following format:
------------------------------------------
From: (that's your name)
To: Anders Lattermann (Yep, that's me!)
Subject: Imagine 4 everybody!

You can use one of the following addresses:
-------------------------------------------
FidoNet: 2:201/411.24
AmigaNet: 39:164/100.24
InterNet: [e-mail]

I want the text in the following format:
------------------------------------------
In the text I wan't you to write the following as start:

"Imagine 4 everybody! + path."

Where the path tells me where to put your message. Path goes like this:
(Upper/Undercase doesn't matter)

1. What?

Choose from:

* Idea
* BugPC
* BugAmiga
* NewProduct
("NewProduct" is for totally new products you'll like to see from Impulse.)
* Hi
("Hi" is for Mikes request of some positive feedback. Short things like
"Best 3D-program i ever used! / Anders Lattermann" is what I'm thinking of
here).
* Wanted Textures/Attributes

2. Where?

Choose from (you don't need to write the word "editor"):

* Project Editor
* Detail Editor
* Forms Editor
* Cycle Editor
* Stage Editor
* Action Editor
* Spline Editor
* Misc (Use Misc for everything you don't find a good headline for).

3. Finally. The text that describes the matter as short as possible. Try to
keep it under 3-5 lines. This is _important_ this thing is already beginning
to be very big. Think twice before sending the message of, if it isn't a
shorter way to say it. The "I would like" part can definatly be kept out, we
already know that you want this feature, otherwise you wouldn't have sent it
to the list :-)


Example for a bug in the Amiga version:
---------------------------------------

Imagine 4 everybody!/bugamiga/detail

"Whenever I use the quit command in the meny. My computer explodes."


Example for an idea:
--------------------

Imagine 4 everybody!/idea/project

"Built in "count the sheeps" game when Imagine renders."


I think you got the grip of how to do it? If not email me. Speaking of
email, I get my email on disk from sweden where I normally live (I'm in
France to sept 31), so email takes about 1-2 weeks (on occasion with bad
timing more) to go to and from me.

Closing date for suggestions and bugreports are june 31. I will there after
put the complete list together and mail it out. Voting will be done to
august 31. Anyone who could put together a good program or ARexx script that
could automate the counting for me? Would be extremly helpfull. I still
haven't heard from anybody. Come on!

This finally gives that I can send a list to Impulse and mail it out on the
net just when the gang at Impulse are done with their summer vacations and
comes back to cook the next release of Imagine together. And this time, with
your help, it could be Imagine 4.0 with all the features everybody wants to
see. In other words: Imagine 4 everybody!

Subject: neon tubes

From: Mike McCool <[e-mail]>

Hey guys, and guyas,

    Thanks for that post the other day, about how to make neon
tubing.  I tried it with very satisfactory results.  Uploaded a frame to
aminet, under pix/trace, called NeonCool.lha.  Lemme know what you think.

    What I'm still blundering with is trying to set up a background
plane, for the neon tubes to actually glow against.  So far, I can't seem
to get that nice soft glow of color that neon gives surrounding objects.
The tubes themselves are way cool, especially in the dark.

    Mike H's suggestion for extruding along a path was perfect, but I
can't make Gerard's trick of that reflective background plane work for
me. Thanks anyway, both of you, for posting your ideas.

motion blur, you need to use an image processing program like ImageFX, or
ADPro.

soft shadows, not really sure yet, been trying but haven't gotten it yet,
Ive been playing with falloff lights and the softlite texture on lights
and objects to see if that would do it but it hasn't yet.  Am still going
to try afew other things as time permits. If I get it I'll post it.

Boing effect, the boing effect will let you squish an object. you can
have a ball bounce off the ground and give it a more realistic look when
it hits the ground than if the balls shape stayed perfactly round. Or
have a logo fly into the middle of the screen and as it stops suddenly,
the logo could be squeezed a bit and then go back into shape, this could
give the logo a more flexible look and not so stiff of a feeling. Im sure
theres a better explanation, but this is the type of thing I use it for.
Kind of like when a cartoon character stops suddenly and he gets a bit
out of shape..

well, if your using the Amiga version Essence does a great job.If not then
try using the priority button along with full scale value
at maybe 150-200 if your using 3.0. Set the priority to a lower number
than your textures..Not sure if this will work but the best I can do

Try:

pub/aminet/gfx/3d/im3tex.lha

on Aminet, the readme is:


This archive contains pictures of all of the regular textures that come
with Imagine 3.0.  (Pictures of the light and fog textures, as well as
the animated textures, are not included.)  You may upload these pics to
other online services as long as the archive is kept intact.

Steve created pages 1-7. I added page 8 with these textures:

veneer, beammeup, dancsprk, crumpled, dripdrop, fakely, filnoiz, fireball
spark, nebula, tiedie, and twinkle.

To make the collection complete we need:

fogpaint, fogtop, ghost, metals, refnoiz2, zbuffer

TO ALL,

    I have lately made a  cycle object that consists of a number of
smaller objects grouped together .Whenever I would like to MORPH a specific
object item of that Cycle group , I have to CREATE a new Cycle OBJ that has
the new specific item in the place of the old one -in order to morph
between them in the action editor (By morphing the whole Cyclegroup)-.
    As you understand this is a little bit disk space hassle because I
have to use the same object twice . IS there another way to do so
(preferable *IN* the Cycle editor) without having to loose disk space for
NO apparently reason ??
    I am looking forward hearing a solution .

 designed to be wrapped without seams showing. Well the clouds liiked great

Actually, these math libraries _DO_ speed up operations that use them...

Imagine, VistaPro, and some others do _not_ use these libraries, which is
why there is no noticable speed-up when using them.

The libs are 100% compatible, with no loss in accuracy or anything, so
why not drop them in and let the programs that use them - use them?

The softlite texture is for the edge of the light beam as it appears on
the object or ground.  An object's shadow is sharp.  I don't think that soft
shadows have been programmed.

Nope! Those libs are only for floating point use. The integer version
uses fixed point arithmetic (I assume) and so Impulse probably have
their own routines built-in to Imagine that operate on these fixed
point numbers. Imagine.int should use no libraries for math either.

This paragraph is correct. This is also why Impulse have placed the
math calls inline. Otherwise every time you wanted to do some math
function, it would go through the library to find how to multiply
rather than just using the appropriate FPU instruction. This may
seem like a tiny bit of overhead, but realize that Imagine does
_MILLIONS_ of multiplications/sines/cosines/etc then the little tiny
overhead adds up :)

This is also correct :) You will get an illegal instruction trap GURU.

ImagineFP uses inline FPU code so nobody will ever notice any speed
improvement. Or in simple words :) ImagineFP doesn't use any system math
libraries.

The integer version of Imagine DOES use the system math libraries, but who is
using the INT version when you have a 68882 in your computer.

Yes, ISL, the Imagine Staging Language, is a shareware package that lets
you convert stages to and from an easy-to-manipulate ASCII format.  It's
currently available only for the Amiga, and not yet for 3.0.  If you
have Imagine 2.0, you can use ISL and Imagine 2.0 to set up what you're
describing, then import the final stage into 3.0 and render (or just
render in the older version if you don't need 3.0 features).

It's available on Aminet or most of the online services.  The current
version is 2.0.  It's not protected or anything.  Get it and try it,
and register if it suits your needs.

There will be a version for Imagine 3.0, once I get the file format info
from Imagine.  Assuming there is interest, that is.  :)

Yesterday, I had psted results that confirmed that imagine.fp does not use the m
ath libs at all. Imagine.int may well use these libs, but if it did, it was stil
l 50% slower (apx) on my 040. Too bad, it was nice to dream.

   There is a new program on Aminet called SnoopLibs (I think), which

   The probelm is with DP4, not Imagine. DP still doesn't support

Date: Wed, 01 Jun 94 07:48:00 PDT
From: Stethem Ted              5721 <[e-mail]>

  I have uploaded an animation called JollyRoger.lha to the aminet under
gfx/anim.  It is a test animation using bones and brushmap tacking to create
a flag of the Jolly Roger waving in the wind.  It only took one evening to
do and could definitely be improved but it shows how bones can be used to
deform a flat plane into things like rippling flags, drapes, etc.  I have
found out how to assign my big and small subgroups better since doing this
animation, so it is possible to have more fluid motion.
  I found that brushmap tacking should be locked to the initial state chosen
for the morph object since choosing the default makes the brushmap "lock" to
that default shape, i.e. it doesn't move with the object.  I think the
default state is meant to act as an absolute reference state which defines
the primary object and any shape, brushmap, texture, etc. change is applied
only to following states.
  I have found bones will articulate all my once static objects, and once
all the subgrouping assignments are determined, it is much easier to animate
compared to the cycle editor.  Not only that, the motion is much more fluid.
 However, the making of the subgroups is very critical in defining how the
object will move.

    IT is really good idea to do so . A REQUEST from IMAGINE's users to

WHAT ????
    Don't get me wrong !! Finding IMAGINE's problems and giving suggestions
to Impulse to REdebug the program OR EVEN make OTHER functions works is a way
in progress . BUT isn't that waht ALL we - THE layal AMIGA-Imagine users DID
(I say AMIGA because this is the majority of the people in this list including
me)- . As we were waiting for IMAGINE 3 to come along , we were talking
about our thoughts , wishes , DREAMS !!! BECAUSE , that is what they DID remain!
    NO , I feel that IMAGINE is MY place to live , it is really my best
choice programm ...BUT I am a little dissapointed!!!
    SURE , Imagine 3 includes some good functions . IS IT WORTH the wait
JUST IMAGINE , we were waited for  1 +1/2 years for the programm to arrive(or
maybe longer) since the firsts announcments of this version . THEN , there were
TOO much talk about it .SO many good features ...SO MANY DREAMS!!
    AT last Imagine 3 is out , UP AND RUNNING , with some MAJOR drawback
WHICH Impulse seemed that ignored them . I don't want argues .ONE is true.
AND I am afraid that NOONE can tell that I am wrong .THOSE patches that fixes
some BUGS in Imagine (and I think that they will follow)  IS A FACT!!
    I am sure that there were PLENTY of time to USE their TESTusers to do
that work ,  and if those users where SO S*U*ID NOT to see the MAJOR bugs
that Imagine 3 HAD and there are still to come....THEN that was THEIR fault!!
A company that wants to be PROFFESSIONALs they would do so...
    SO , to get in the subject , what is the reall meaning of such a

AT least the previous thoughts were NOT heared by IMPULSE!! .IT seems to want to

Subject: math libs
Date: Wed, 1 Jun 1994 13:20:13 -0500
From: Kent Miller <[e-mail]>

While I haven't seen much of a difference in rendering times in Imagine
when using these new libs, I'd still recommend keeping them on your
system. A 3D renderer like Imagine uses highly intensive math operations
and probably bangs the FPU directly. I know I would as an assembly
programmer myself. It doesn't make sense to try and get as much speed
as possible into a program and then resort to calling inneficient
C library routines nearly every other CPU cycle during rendering.
 Since the new libs were optimized in pure assembly, they should
give faster results when used. The benchmarks that came with it may
be inaccurate or the may be true, but if you use another program
that uses the math libs directly, you probably will see that speed
increase that is promised. Something like ADPro's JPEG conversion
routine uses the libs I believe. But anyways, I'd recommend trying
different programs out before dumping the libs. The libraries certainly
aren't hurting anything or are inaccurate (at least no gurus here
:-)

Hmm, I've done this before....ah here it is.  Also, you may want to try
adding an axis seperate from your object and make that the light source(I
haven't tried it, but it might work)


--------Include from old post------------
The best setting I got for a lightbulb
was as follows.

Make the bulb glass(transparency 200, 200, 100 or what ever, I used the settings

       from Understanding Imagine 2.0)  Not sure if you need this since you are
       going to be setting fog.  I need to play some more.

Make the object a light source by clicking on the light box in the attributes
  requestor.  No need to set the bright box.  In light requestor select
  spherical and put the light to 400 400 250, kindof yellow.  Select cast
  shadows if you like.

Put the object axis of the bulb where the filiment of the bulb would be.
    (shift-M to move the axis)

Set the fog length as suggested by another Imagineer.  You will have to play
with this as it depends on the distance from the object axis to the edge of
the bulb.  My bulb was 40 units across(turn on coords and measure) and my
fog length was 10 or 15, can't recall which.  The smaller the setting, the
more opaque the bulb will be.  The fog will be the color of your object.
My bulb was white.

Some weirder results occured when the object was not transparent.  It still
seemed to emit light, but the bulb was completely black.  Turn on "bright"
and the bulb turned white(but it didn't look right, kindof flat looking").
I makes sense to make the bulb transparent and this seems to work the best.

    Soft shadows is easy but a real pain...

    Think about how lights work in pretty much every
ray-tracing/rendering environment. Lights are point sources. Nothing
in reality is a point source.
    A point source can only cast a sharp shadow. To simulate
soft-shadows you have to create multiple point-sources which are
closely grouped around a central axis. All of the individual
lightsources that make up the larger bundle of lights must all have
intensities that are a fraction of the main bundle is supposed to be.
    I'll give an example of a soft-shadows 'real' light source
that I've created...
    I'll assume that the intensity of this packed bundle will
ultimately be 255,255,255. I've had decent results with packed bundles
consisting of 21 lightsources or more. There are several ways of
creating the packed bundle of lightsources. This is just one method.

 CREATING A SOFT SHADOW LIGHTSOURCE

    1. Figure out how many lightsources you will have in the final
packed bundle. In this case it will be 21 (not exactly arbitrary and
you'll see why).

    2. Figure out the final intensity of the packed bundle. In
this case it will be 255, 255, 255 (the default value for an Imagine
lightsource). The packed bundle (with all its lightsources) must emit
as much light as a similar single lightsource otherwise you get too
hot a lightsource.

    3. Divide the final intensity by the number of lightsources
(step #2 divided by step #1). This gives the individual intensity for
any lightsource that makes up the packed bundle. In this case
255/21=~12.1.

    4. Add a primitive disk with radius of 100 and 10 sections.

    5. Add an axis and place it at the center of disk. If you're
using defualts the axis will autmagically appear at the center of the
disk (world center of 0,0,0)

    6. Select the axis you just added and enter the Attributes
requester.

    7. Make the axis a Lightsource with Light Intensity settings
of the number you got in step #3. In this case it's 12.1, 12.1, 12.1.
Have the axis Cast Shadows. If you're using 3.0 and like Lens Flare
disable the feature for now.

    8. This bundled source will act the same as point source. With
that in mind determine whether the light should fall off. For these
purposes have no light fall-off. Exit the Atributes requestor.

    9. Copy the axis (R-Amiga C), paste it (R-Amiga P), and move
it (m) to the top of the disk where the the edge of the disk and the
section parts meet.

    10. Copy and paste the axis at every section around the outer
rim of the disk. This will result in 10 axes at every section and one
axis in the center. Delete the disk to get it out of your way.

    11. Group the outer axes to the center axis by selecting first
the center axis then every outer axis (using shift), and finally
grouping the with (R-Amiga G).

    12. Copy this entire array of 11 lightsources and paste it.

    13. Select one array and scale it by .5. This should bring the
outer axes closer to the center.

    14. Rotate the same array by 18 degrees. This causes a stagger
of the inner array as compared to the outer array.

    15. Enter Pick Objects Mode and delete the center axis out of
one of the arrays (you only want one center axis). Group the
non-grouped axes to the center so that every axis is grouped to the
center axis.

    16. Enter Pick Groups Mode and save the entire bundle.

    A word for Imagine3.0 users. If you want Lens Flare to operate
for this bundle select the center axis and enable the flare. Having
all 21 axes Flare would be tediously slow, and it wouldn't look good.

 === Using the Bundle in the Stage Editor ===

    A warning. This bundle object is made of 21 lightsources.
Rendering times will decrease with its use for obvious reasons.
    The bundle only works in Trace Mode (obviously) because it
needs to cast shadows.
    The current bundle only works in "Studio Situations" or
situations where the bundle only has to work in a near perpendicular
fashion. I.E. The pyramid of spheres on a flat plane would be a studio
situation. You can aim a lightsource as if you were in a studio or
soundstage.
    The bundle must always be perpendicular or near perpendicular
to the subject. You can track the Y-Axis to the subject to achieve
this.

    Each of the axes on the bundle emmits a bit of light. It's the
multiple shadows cast by each of these lights that creates the soft
shadow. You must be prepared to experiment with the scale of the
bundle. Scales should always be done (L)ocally. It's pretty easy to
figure out how large the bundle should be if you understand how the
bundle works. This I leave up to you as it is next to impossible to
explain the 'right' scale setting...

    Always remember that the more lightsources you use in your
bundle the better the results, and sadly the longer the rendering
times. You have to make a trade off between how large your soft-shadow
fall-off will be compared to how many lightsources you have in your
bundle. If your soft-shadow area is too large, and you don't have
enough lightsources, you'll see many clearly defined sharp shadows.

    This the only way to created a soft-shadow lightsource in
Imagine, I believe. It may be a pain in a$$ but it works. It should
only be used for stills for obvious reasons. Only use the bundle where
necessary. For instance, in a conventional three point lighting setup
you only really need the bundle for the Key and Back lights. The Fill
doesn't cast too noticable shadows and can therefore be a point
source.

    Good luck...

    Oh, one other thing. Specular hits look way cool with light
bundles. I mean much more realistic...

Don't know if this merits a post to IML, but you seem to be correct. I
messed around with the FrenchWindows texture and the edge of the shadow
on the ground was soft, but the shadow of the object was sharp. A very
odd effect :) BTW, the FrenchWindows texture asks for a number of
horizontal and vertical panes, yet it makes an infinite number of these
"light squares" on the ground. Have you run into the same thing?

If you are using Imagine 2.0, maybe even 2.9(I deleted it from the HD
already so can't check), the palette locking option does not work.
So each frame of the anim has its own palette.  DPaint only supports
single palettes so it really can''t work with multipalette anims.

You could use something like ADPro to process the images & have them
use a single palette.

One question I've had is why does imagine make my anim width 384 when
I only told it to do 368?  Very annoying.

This may not be what you're talking about but, when you make an object a
light, the light comes from the point of the axis, not the faces.  So if
the axis is at the center of a box, in trace mode the box itself would be
blocking the light (it should be well lit on the inside).

Yes, I am aware of this, but I felt it couldn't hurt to see if it might
work on an objects shadow as well..it didn't give me any errors when I
renderd it this way, and sence we were promised soft shadows in the
newsletter, I thought maybe it was just not documented and the only way to
find out shuch things is to experiment..which basically is all I am
doing..and basically hoping I might get lucky..after all if I figured out
a way to do it you would probably like to know about it..wouldn't you?

This is how I find out how to do alot of things, by trying anything and
everything I can think of..

Hmmmm? OK that sounds better, I'll have to give it a try and see how well
it work...Does seem like it might be a bit of a RAM hog though,
considering the size it would have to be, and how far away you would have
to place it for the stars to become small enough to become little
dots..but then  thats only if you had a thick congestion of stars...But
as I haven't tried it yet, I'm only geussing about it...does seem like it

Well, if I understand you correctly you can start the cycle at any point
by using the Initial Cycle phase, you will still have to load it twice
because there isn't Transitions anymore, but you shouldn't have to save
different versions to disk..just the one, unless your morphing attributes
and textures..Intial Cycle phase works like this..if the cycle object is
say 100 frames then to start at frame 50 you would use 0.5000.

Hope this is what your looking for?

From: "Glenn M. Lewis - ICD ~" <[e-mail]>

Hi, all.

    A few months back I talked about a program I wrote in C++
called "Melt", and showed some examples of chess pieces melting, etc.
I couldn't give out source because I was writing an article on it.

    Well, the article has been published in the July 1994 "Annual
Graphics Issue" of Dr. Dobbs Journal, and is the lead article.  It's
called "Morphing 3D Objects using C++".  I believe that I'm still not
supposed to e-mail out source, but Dr.Dobbs has made the source code
available on their FTP site.  I'm afraid I don't have their site
address now, but wanted to let everyone know anyway because I'm about
to go on yet another business trip.

    So anyway, I hope you enjoy the article.  I enjoyed writing
the program.  Feel free to e-mail questions & comments to me, but I
can't promise that you'll get a fast response because of my travel.
In fact, it may be on the order of weeks that I will be able to reply.
Sorry about that.  I don't like it either.  :-)

        The following 10 steps show how obtain a scallop  sea-shell  (or
something similar to it!), perhaps I've a problem (credit for thi little
tutorial goes to Wizard):

1.  add axis
2.  add lines (use front view) like this:

                                z
                    __    ...   |       ...    __
                .__|  |__|      +---x      |__|  |__.

              -130         .... 0 ....              130

3.  invoke the extrude req:
    to length 200
    scale x   0.5
    sections  10
4.  add a primitive tube: radius 120
5.  scale down the tube: 70% only y (shift-y)
6.  adjust the tube position to cut the extruded shape like this:
                          _________
                         /         \
                        /\         /\        top view
                       /__\_______/__\

                        |           |
                      cutted      cutted

7.  select extruded shape then tube and slice them
8.  delete resulting objs except the 2 'planes'
    ('planes' should be part.2 and part.3):
                          _________
              part.2     /---------\

                           and this          top view
                          _________
                         /         \
              part.3    /           \
                        \_         _/
                          ---------

9.  select first part.2 and then part.3, join them
10. invoke mold req and conform to sphere:
    sphere radius 100
    object radius 320

        After all these 10 steps, the resulting shape should  be similar
to a scallop sea-shell except for its too planar look: anyone has  found
the proper 'conform to sphere' (or what?) to show it much realistic?


P.S.:    hey listers, time is money so I've uuencoded what I've obtained
         after 10th step, see Ya l8r.

P.P.S.:  thanx goes to all who reply my previously '3d seashell' message

Did you render one frame that had all or most of the colors needed in the
anim and then use "Specify File" from the Pallete method requester and select
the frame with all the colors needed as I mentioned above. This has
worked great for me and Ive had no problems as of yet..This is of course
only possible with 2.9 and 3.0...if your using 2.0 you need to send them
to an image processor, Brilliance, or for HAM PhotonPaint works
great..and is fast at playback too..

[Impulse bashing(from what I could tell) deleted]

I'm sorry, but... I can't agree with you bashing Impulse like this.  I think
they have really done a good job in listening to our requests.  They have
come a long way in listening to the customer.  They just released texture
info(YEA!!!!!), they included lens flares(even though they don't work
perfectly, I get a feeling this was a last minute item due to overwhelming
user requests here on this list), they are releasing bug fixes to the net
(even though there are no revision numbers:).  They are more active with
us than ever.  I think its great!

And the new features in 3.0 are wonderful.  Have you used them yet?  All of
them?  I know I barely have enough time to skim the surface and I have been
continually amazed.  Bones implimented in a more powerful manor than Lightwave
(from what I understand) with a promise to make them easier to use.  Particles!
Deformation tool a la Caligari!  Textures out the butt!!  etc etc etc.

If you have a complaint, as Impulse has stated, make a specific one, and
they will probably try and correct it.  General comments like "Impulse stinks"
isn't gonna get you what you want.  I don't think anyone cares if you
critisize Impulse(I do it all the time), just do so constructively(who am
I to talk?).

Subject: SPOTLIGHT BEAM
Date: Thu, 2 Jun 1994 02:09:10 -0700 (PDT)
From: "Randy R. Wall" <[e-mail]>

I have had many requests for the Spotlight tutorial I meantioned here,
so here it is for all to read and use.

I will explain a persice method for 2.9/3.0 and a fairley persice method
for 2.0 and 2.9/3.0.

Now this takes a bit of work but once its done you can reuse this light
many times and it will leave shodows as well as light up whatever it
hits.( The Persice Example works only in 2.9/3.0 ). But the fairley persice
method works in both 2.0 and 2.9/3.0 so if you don't need a persice spotlight
you may want to skip ahead to the 2.0 version as it takes a bit less work
to make.

-Persice 2.9/3.0 version

Heres ONE way to do it, make a cone with an open bottom and size,
and shape it to how you would like your spotlight to appear in the
sceene, then move the axis of the cone to the very top point of the cone
making sure that the axis center matches up axactly with the top point of
the cone. Use shift M and shift Z and move the mouse to do this.

 Then make the cone the color of the light you are planning to
use and then make it BRIGHT, now go and set the Filters to 180,180,180 or
240,240,240 depending on how translusent you want the beam. This will make
it so that when you render it you can see threw it. Now select the object if
its not already and use the Transformation requester to move it to
Position Z 100 and leave the rest of the positions at 0. Now we can save
this object.

Now you nead to make a test project to set the light up in so we can get
the proper setting for our light. Once you have done this load the cone
into the STAGE, now add a light and use the Transformation requester to move
the light to position Z 100 and leave the other positions at 0 as we did
with the cone in the Detail Editor. Save this and goto the Action Editor,
find the light and set it to Conical, Cast Shadows (2.9) or Point Sourse,
Round Shape, Cast Shadows (3.0) and set the color to whatever you set
the cone to. Save this and go back to the Stage Editor.

Once your back in the Stage Editor Go up to the Display Menu and select
Light Lines then use FIND to select the light.

Now use the Transformation Requester and Align  X to -90, Y to 0,
and Z to 0. Now the light should be lined up with the cone pointing down.
So hit the S key to size it, and size it till the center light line in the
Right View reaches the bottom of the cone. While still in size mode go to
the Front View and Zoom in on the bottom of the cone as much as you can
while still being able to see the outer edges of the cone. Now hit
Shift X and then just the L key. This will put you in local size mode of X,
now size the light lines till they match up perfictally with
the outer edges of the cone. Now do the same thing with the Z size
using the Right View and Shift Z then L keys. You need to do
them seperately as they will not match up otherwise. Whew! almost done,
This may sound hard but its really quite easy. You could actually use this
as is in the stage, but just make sure that if you move or rotate either
of them you select them both together. Sence it is only a simple matter
to make them into a group I will continue.....

OK, I hope someone gets some use out of this? if so let me know...

Now that we have this all set up go to the Transformation Requester and
select size, write down the sizes of X, Y, and Z exactly as they are and hit
OK and after all this work why not save it..

Now go to the detail editor and load in the cone object.
Now add an axis and select it, use the Transformation requester
and select Alignment and set X to -90, Y to 0, Z to 0,
then select Size and type in the numbers you wrote down, and
then select Position and type in X 0, Y 0, Z 100. and select OK. Now set
the Attributes of the axis to a Light and set the light to Conical, Cast
Shadows (2.9) or Point Sourse, Round Shape, Cast Shadows (3.0)
and set the color to whatever you set the cone to . Now group the axis and
cone together and save it. You can now move this object freely around in
the Stage and Action Editors as one object.

 If you want the light to have transparency of the cone linearly
over it's length ( basically Fade Out at the end ) you will need to size
the cone maybe twice as large while leaving the Axis Light the same size
and then use the Linear Texture on the cone and rotate the Textures Z axis
so that it is pointing down and drag the Texture axis down to slightly above
the Axis Lights Y axis line. If you made the cone twice the size this would
be halfway down the cones lenghth. Then set the color of the texture to that
of the light and the Transition Z Width to whatever looks good for your
particular light, I like  100 or 150, for a 500 unit tall cone, then set
the Filters for the Texture to 255, 255, 255. You would also have to set
your Axis Light's Attribute to Diminish Intensity 2.9 or Controled Falloff
for 3.0 to pull off the full effect. You may need to play with this to
get it just right though.

-Fairley Persice 2.0 and 2.9/3.0 version.

Make a cone with an open bottom and size, and shape it to how you would
like your spotlight to appear in the sceene, then move the axis of the
cone to the very top point of the cone making sure that the axis center
matches up axactly with the top point of the cone. Then make the cone
the color of the light you are planning to use and then make it BRIGHT,
now go and set the Filters to 210,210,210 so that when you render it we
can see threw it. Now COPY the cone and align the X axis to -90
locally in the Transformation requester by using Tranform Axis Only and
Alignment. Now resize the Y axis locally till the axis line not letter
reaches the bottom of the cones Bounding Box, then resize X axis locally
till the axis line reaches the very end of the Bounding Box, and then do
the same with the Z axis. Now change the Attributes, turn off Bright, set
Filters back to 0,0,0 and set the object to a light and set it to Conical,
Cast Shadows (2.9) or Point Sourse, Round Shape, Cast Shadows (3.0) and
set the color to whatever you set the cone to. Now go into
Edit Points mode and delete all the points in this object. You can now
PASTE the old copy and group the two objects and save them out as a Spotlight
This method is easier than the other one and produces good results as well,
I just feel the other method is more presice if you plan to zoom up on
something like a logo and have the spotlight moving acrossed it.

If you want the light to have transparency of the cone linearly
over it's length ( basically Fade Out at the bottom ) you can use the same
method as I mentioned above with the Persice Spotlight.

 Whew! Now theres a SpotLight!

While even this is not a perfect SpotLight it is a very good one, the only
problem with it is that if you shine it threw something the Bright Cone
object will still show through the other side, you maybe able to limit
this by making the cone more transparant with the Filters, but I think 220's
or 240's work pretty good..Or buy making it a fading SpotLight.
It also doesn't have edge transparency but I haven't tried to figure out
how to do that yet. I imagine you could use multiple cones at different
Filter rates and sizes to get something close to it, in 2.0/2.9
or use the global HAZE effect and the SOFTEDGE texture in 3.0.

Once you set up the basic object in Imagine you could just use it and make
changes to it as needed.

I do think if you try this SpotLight you will like it
as it works great for RayTracing when you want an object in the middle of
the SpotLight and yet have other lights coming from other directions,
the Spotlight will still light up the object and leave its beam and  shadow
and works fine in Global Fog unlike a Cone set to FOG as I have seen others
suggest.

Sorry for the huge toturial, but I couldn't think of any other way to
explain the spotlight.

If you try it let me know what you think of it?

You can make this spotlight work so that you can see the light it is coming
from as with a car headlight, but that is another Tutorial in its self, so I
will upload one that is already made in such a fashoin to the net soon.

Hope I didn't mess this up when I edited it for IML, but I read it a few
times and it looks fine, if you have any problems let me know.

Enjoy!

The Siggraph organizers have not started setting up the schedule for
the Special Interest Groups yet. When they do, I will set up the meeting.
I am shooting for Wednesday, 7/27/94, at 1pm (I think that is the same
time I chose last year). I am looking for any interested party (preferably
someone in the Orlando area) that could tote a vcr and monitor to the
meeting. I will be bringing a Hi-8 deck, but we could really use a VHS
unit. Any volunteers?

Subject: light through trees
Date: Thu, 2 Jun 1994 13:33:30 -0400
From: [e-mail] (Jude Anthony - DMC)

Hey, everybody.

Someone recently mentioned a JPG out on AmiNet with light streaming through
the trees.  I also recall a Toaster-created animation on something like
Unsolved Mysteries, where the UFO lifted off from behind some trees and
wonderful beams of light streamed out from the holes in the foilage, changing
as the ship moved.  I want to re-create this effect.

The closest thing I can think to do is render a scene without the beams, then
use that to create an inverse picture, import the IFF to Imagine, and extrude
it, scaling the end-point.  I'm not certain, though, if this would allow for
movement.

I'm hoping somebody out here has tried this before and knows how it's done.
Any tips would be appreciated.

Jude Anthony

automatic to you, but this list seems to run much better than other ones.
 It has much fewer relay bounces than other lists and bounce nodes are
quickly taken care, not like some lists, where bounces start bouncing off
each other in some kind of chain reaction.
  So, Dave,thanks and keep up the good work!

Subject: Altitude States Maps
Date: Thu, 2 Jun 94 20:44:13 GMT
From: Andrew Nunn <[e-mail]>

A few weeks back, I posted an article about using Altitude maps with
states. To summarize, the alt map is applied to a flat state of the
object and subsequently wraps around the full width version. I managed
to use this method successfully a couple of times, but have now
encountered an anomaly. I have managed to create an object which appears
to only alt wrap in the -X part of the object. I can't decide if it
is due to something I've done wrong,a bug or whether I'm just 'pushing
the envelope'. If anyone wants to take a look and give their tuppence
worth (two cents), then I could mail a uuencoded object and map to them.

Thanks in advance

well, I like to model my mountains and find the linear and pastela
textures in combinations work really well. Use a linear for snow, near
the top and and one at the bottom for grass and different pastela
settings for them both as well as one inbetween, you will have to play
with them to get what you want..for cliffs crumpled and dirt might work
nice together..can't give you any specifics as this is all up to what you

Ya, this is true, but need not be, all you have to do is load the configs
into a text editor and rearange them so that the ones you use
the most come up first, basically costumise them in the order you would
like them. Then you can have your favorite one at the very first position
and when you click the preset button it will be the very first one on
the first requester and your other favorites will be right below it. I
actually think this is easier than typing them in myself.

Hmmm? well I don't know how to solve this one for you. I could try it
myself but am sure if you have the presets right and it is still doing it
then its something in the programing for the animations. sorry?

Does anyone else maybe know why Imagine is changing the screen sizes when
Jason has it build an animation?

I'm sure Jason would like to know why.

Come on guys!  Why all the gyrations to get a good looking starfield!?

Summary of a post I made long ago...

Take the CSG sphere.  Color it BLACK.  Make it BRIGHT.  Add the CONFETTI
texture (Im3.0), set the V1 and V2 numbers to .54 and .55 so as not to have a
ton of stars.  Set the two colors to  200,200,200 and 240,240,240 (or whatever
turns you on.  Scale the Im3.0 CONFETTI texture to get the "stars" the size you
want them, render to see how they look and adjust if need be. Place scene
INSIDE the sphere.  Voila....instant gorgeous stars.  You can even add the
NEBULA to a sphere fog object in the distance somewhere.  :)

    Yes, what you will find on the Dr.Dobbs site is SOURCE ONLY.
I have personally compiled it on a UNIX workstation, an A3000, and a
486PC, and all work fine with only slight modifications in order to
passify the quirks of the respective C++ compiler.

    However, I am currently 800 miles away from home, and do not

Subject: Boney Flags
Date: Fri, 3 Jun 94 13:54:40 CDT
From: [e-mail] (Thomas Setzer)

Well, Teds anim inspired me to continue my experimentation with bones and
flags.  I followed Scotts suggestions and got the results I was looking
for.  I will upload the animation to aminet at lunch today(I started turning
it into an anim before I left for work today.) It will be called USFlag.lha and
will eventually make it to /pub/aminet/gfx/anim

This was just a quick and dirty test I did in about 2 hours (including painting
the flag).  I need to add a couple more layers of bones.  This one only used
6.  I did more with the flag then Ted did with the Jolly Roger.  I was trying
to get the look of a flag blowing in a weak wind instead of a stiff wind.
Some things to notice:  The stripes get streched, but it is hard to notice
since they are stretching in the direction of the stripes.  The more noticable
stretching takes place along the edge of the star field.  With some work I
think I can get a flag to behave nicely.

Some other neat effects I noticed while experimenting was what happens when
you move the bones(instead of rotating).  I got a kind of crumpling effect.
Try twisting(rotate) the bones around all the different axes.  I haven't
tried scaling yet...hmmmm....

These things are VERY powerful.  I think we could come up with some very
interesting uses for these other than the obvious character anims.  Any
suggestions?  You Lightwave people(who've had bones for a while now) come
up with any good uses yet?

BTW, I will include the flag object in the USFlag.lha if you want to look at
the setup of the subgroups and bones.  You will have to supply your own
image, however.

    There is a program called Shelly that will do this, generate several
types of seashells: ammonites, nautilus, etc.  It is available on aminet
under gfx/3dobj, I believe or gfx/misc, can't remember exactly which
subdirectory it is under.  I have used it to generate all the default shells
and it also allows for customized shells but I have not investigated how to
do this.  There was also some obscure step to get it into Imagine format,
also, since it produces seashell objects directly for POV, Real 3D, and .DXF
if I remember correctly.  It doesn't directly produce Imagine format but it
was some small step to get an Imagine object out.

   Hey, our good buddy Mike Halvorsen got himself quoted in the July issue
of Amiga World.  In the Overscan section, in the article titled "Vendors
Pledge Support for Amiga ... With or Without Commore", in the last
paragraph:

   A more down-to-earth -- but perhaps even more refreshing -- comment came
from Mike Halvorsen of Impulse, the developer of Imagine.  When asked about
the significance of Commodore's departure, the ever-forthright Halvorsen
said, "Who gives a #*!#*?  They've been dead for 10 years!"  Exaggeration
aside, that might just be the point: The Amiga community -- Amiga users,
developers, vendors, publications -- is, and always has been, us!

  Also, in the same issue, in the Digital Canvas section, are two images
from people using Imagine including one that is a single frame from a
40-minute music video animation.  So, it appears a few people are using
Imagine professionally.

Subject: Unhook & Bones fish problem and a fix.
Date: Sun, 5 Jun 1994 02:41:42 -0700 (PDT)
From: Jeremy White <[e-mail]>

Does anyone know what the unhook function does?  I thought that it might
affect the groups (after selected, the group structure changes -- or does
it?)  After you do a refresh the bone structure is restored.   It never
visually changes.....   Any clue what this does?

I am working on my fish using bones still and have come up yet another
brick wall.  The fish is composed as such ----

     1.)  Main axis - everything is grouped to this.  Especially the
          non-moving (not boned) parts of the fish. (like fins)
     2.)  Body axis - This axis contains the body-mesh of the fish (not
          including head or tail.) This axis has the main axis as a
          parent and bone axes (first one only) as children.
     3.)  Bone axes - This is a chain of axes (5 of them) grouped
          properly for bones.  The first axis has the body axis as a parent.

Ok... My problem.  When I have the main axis selected and choose update
bones, ( and have moved the bones axes) nothing happes.  (ok, no problem,
that object has no bones) so I select the body axis only.  Ok, it works now.
(as I had expected.)

So, I bend the fish and create a state (right tail flip.)  I check the
grouping box only (not the shape box, as the instructions suggest to avoid
adding extra info to the object)  I then animate it using bones anim.
The backbone animates fine, but the body is not updated (it stays unbent.)

Is this because it is a second level group in the object????  Do I have
to click the shape box?? If I click the shape box will the object morphs
linearly!!!!! (see below.)  DOES THIS MEAN THAT WE ARE LIMITED TO HAVING
BONE OBJECTS WITH THE BENDABLE FACES ONLY AS THE ROOT OF OUR OBJECT????

           :-(

-------------------------------------------------------------------------
                     Fix to problem.... Watch for this one....
-------------------------------------------------------------------------

When you morph from between the DEFAULT state to another state (using
bones)  The object will not behave properly.  It might look ok, but it
will morph linearly ( the points will travel in a straight line rather
then bending.  You should create another state (called normal perhaps?)
to morph between.

This is because the shape box is checked in the state requestor.(see
above)

 This is documented in the manual, but only briefly in very small print.

-------------------------------------------------------------------------

Thanks to all the people who have helped me in this first bones effort.
I will donate this object to aminet when done, as it IS a good example of
bones.

From: Jeremy White <[e-mail]>

How exactally does constrain and hook work??  Could it be the solution to
my problem? (below)

I have a chain of axes for bones like this.

    1       2         3        4
    |       |         |        |
    +=------+=--------+=-------+=

Where axis 1 is the parent of 2, 2 of 3, and 3 of 4.
(i.e. select axis 1 in the group mode and they all get selected.)
(select 2 - 3 and 4 also get selected.)

OK ------  If you are still with me this is what I want to do....

            2         3        4
            |         |        |
            +=--------+=-------+=
           /
        1 /
        |/
        +=

I want to move the first axis without moving the others at all.

Ok. No problem, I just select axis 1 in object pick mode and move it.

Here is the catch --- I want to keep the distance between axis 1 and 2
exactally the same as in the first picture.  If it was grouped the other
way (2 parent, 1 child), I could just rotate axis 2, but this way I cant.

Will the new feature of hook and constrain help me in any way????????

-Jeremy White

P.S. If anyone wants the fish when I am done I will upload it to aminet
with texture maps.  The fish is articulated with bones and moves very
realisticly.   (Thanx Impulse!!!!!!)

If you set up a bone animation in the detail editor, then press "cancel"
during the generation of the animation, the bones are left at the point
you pressed cancel.  This can be usefull if you are trying to generate
"tween" states between two already defined states.....

    Okay, since Kinematics is hardly explained I'll offer my
limited info...

    Enter Pick Objects Mode.

    Select axis 2 and use the Freeze menu option. Depending on
what the entire object will ultimately do select all of the World and
Local translations. This keeps the number 2 axis from moving
physically in space.
    I'm a bit iffy on the differences between World and Local
freezes, so I'll give you my best guess.
    By selecting the World freeze your locking the axis (from
moving) in the world. That axis will stay where it is no matter what
the rest of the object is doing.
    By selecting Local translation you lock the local position of
the axis. If the entire object is going to be swimming/moving through
the world then you just want Local translation and no World
translation locks selected. You'll have to experiment with the
differences between World and Local Translations, however.

    Again, depending on what you ultimately want to happen you
want to freeze the rotations on the axis(2). Enter the axis' Freeze
requester and lock out the Local Rotations.

    With the previous Freezes set up select Constrain.

    This is where it gets weird. Since you're using the parent
axis of another axis you can't move it. You have to rotate it. Select
axis 1, Rotate, and the axis you want to rotate on (X,Y,Z).

    You'll notice that axis one stays the same distance away from
the frozen axis 2. Also note that axis 3 and 4 stay in their
respective positions as well.

    Depending on what orientation you want for axis 1 manually
reorient axis 1 with Rotate and CONSTRAIN OFF.


    If you had been working on the CHILD axis of a group then you
would have had to do things differently.

    1. The PARENT axis would have had to be Translationally Locked
but Rotationally freed.
    2. The PARENT of the original PARENT axis would have had to
have been Joint Locked and Translationally Locked.
    3. Rotations of the CHILD axis would have had to be done with
Rotate.
    4. Movement of the CHILD axis (keeping the distance relation
between PARENT and CHILD) would have had to be done with Move.

    Suffice it to say, Kinematically moving CHILD axes is a hell
of a lot easier and more predictable. If you don't know what I mean
take the rotation locks off of your axis 2, and rotate (with
Constrain) your axis 1.


    Kinematics is tricky. Your best bet is just to toy with it. I
am still unclear on the exact the use of Joint Locks. The difference
between World and Local eludes me in the Freeze sense. When dealing
with a PARENT axis and little Freeze control what the hell exactly
will happen? I don't know.  Maybe something totally random. Well,
maybe not, but it looks random...

    Hope some of the above works and/or helps...

    Above all, have fun! It's Imagine!!

I assume you've mapped a black and white image onto the plane and made it
a transparancy map, right?  Try negating the image (reverse the black
and white), and choose 'inverse video' on the map attributes box.

In other words, when using a tranparancy map, or alpha channel, the white
portion of the image should be the part you want to show, while the black
is that part that will not show.  Imagine does this the other way, but
doesn't make the transparent part fully transparent.  It seems to work if
you reverse everything.  (They may have fixed it in 3.0, I discovered this
in 2.0 and have just kept doing it that way because every other program
and standard I've seen uses white as the 'show through' and black as the
'transparency'.)

Hope this helps.

No such site. Bab 5 objects are proprietary and definitely not available

In regards to Ryan Johnson's problem with his venetian blinds,

I don't have Imagine 3.0 yet, but it seems to me that the max brightness
of anything is 255,255,255.  Setting it to 455,455,455 _should_ make it
wrap to 200,200,200 - but in TRACEMODE, maybe it's getting set to zero.

Why not try setting the brightness to 255,255,255 and get back to us!

Hey guys, guyas,

    I, too, have been starfielding.  And I must be missing
something.  The only one I can get to work and look realistic is the cool
one that one of you suggested in which a small object was replicated onto
a sphere-shaped path.  It's the hugest, of course, but it's the only one
in which the stars actually pan with the camera.

    The confetti method looks GREAT, but only seems to work for me
with stills.  If I animate anything inside it, the stars flicker on and
off, new ones appear and old ones disappear as the camera moves.  Kind of
cute and twinkly, but not quite a starfield.

    Not that realism is such a must.  I have to confess to some
dismay at all the fuss to create realistic effects of things that can be
so easily photographed, like waving flags and such.  I video frames like
this when I need them, and dub them into the background.  I understand
the challenge of it, but not the point. I prefer to concentrate my
Amiga's power and Imagine's scope on things that can't be photographed,
like Maralyn Monroe piloting a flying saucer.

  Is it possible to expand the default max world size for trace mode in

can't fit everything I need into a world that only goes out to +16000 units.
  Actually, this might not be a world SIZE problem, as the error message I'm

more of whatever this is???

>Has anyone been able to successfully create a moebius strip?

Nope.  But here's a start for you.  Basically, the moebius strip
is a skinny rectangle.  Bend the two ends up to meet each other
& flip one end 180 degrees to get the twist.


So, in Imagine, I'd start with a simple two point open path.  Bend
the path so that the endpoint meet each other & the shape of the path
is a loop.  Do the bending about the x-axis.  Place the endpoints
exactly on top of one another.  Use the transformation requester to
get/set exact location coordinates.  Then take one point and rotate
it 180 degrees on the local y-axis.

With the path created, you are almost done.  Now just make a single
line consisting of 2 pointer & one edge connecting the points.  Make
sure that the axis is placed on the center of the line & that the
y-axis is perpendicular to the line itself.

You could add a primitive plane, delete 2 points, move & rotate the
axis, it may be quicker this way.  If you start with this plane, only
use 1 vertical & 1 horizontal section.  Hmm.  I wonder what imagine would
say if I were to try 0 vertical sections?

Now extrude your line object along the moebius path.  Use enough sections
to get it as smooth as you desire.  Also, set it so that the y is aligned
to the path.  Otherwise, it won't twist.

What has been created is a flat moebius strip.  If you want to have some
thickness, you could extrude a 4point plane along the path(the y-axis
for the plane should be perpendicular to the plane's surface).

You may also want to add a 3rd point to the path by fracturing or splitting
it.  This will give you more control over the shape.  If you add the 3rd
point after doing the initial steps above, then you won't have to worry
about rotating it on its local yaxis.

In the Action Editor, set the Size of Globals to 0,0,0.  This
dynamically autosizes the Imagine world at the start of each frame.  You
can also set it to any specific size you wish.  In 2.0, you had to Add
the Global Size, and it defaulted to 0.  I assume that 3.0 works the same
way.

Easy,  try this;

In the detail editor:

1. Add a closed path

2. Add a primitive plane, say 40x20 1 section

3. select the plane, choose Extrude: Along Path (the closed path in 1.),
   Align Y to Path, Sections = 100, Y Rotation = 180 ( to give the Moebius
   loop). Perform extrude.

4. You may need to edit the 8 faces where the 1st and last planes join, the
   seem to get twisted.

Cheers

The OctVolume problem may still be encountered if the world is too big.
autosizing will probably not help.  I have 18 megs and have had this
problem with space scenes.  I usually use a very large sphere with the
essence polka-dot textture(very good resultst).  But this large
sphere make the octvolume too big.

To get around that, I've had to select everything & scale it all down.

  I have to disagree here.  I do have 3.0 now, but even with 2.0 I would
consistently set Brightness levels higher than 255,255,255 to get a good
strong light.  And it worked both in Scan and Trace.

     What'd you know, I'm working on it right now and having the same
problems you are. I think I can do it with a doublesided ribbon and a bit
of a cheat (you'd only have limited animation capability...). If you

Nope, none at all. We have had this super powerful tool for about 1.5 years

Seriously, LW bones have been used for zillions of things. And because LW
allows you to save the current translation/deformation as a new object, bones
can be used as a modeling tool as well. Here are a couple less common uses
for bones:
1) map an image to a tesselated plane and use bones to warp and twist the
   image (this is rather cool when animated).
2) use bones to distort the point locations in a particle field to yield
   a psuedo random variation

Been there, done that. This may not help you much, but WP51 doesn't do a
good job with these types of files.  Try changing brightness and contrast
before importing to WP and don't edit the pic while in WP, just print it.
At work I now use Imagine PC which outputs targa, and WP60 which handles
targa files without problems.  I render B&W in Imagine and print to
600dpi printer with ASTOUNDING results.  Using this combination I can
render and print just about anything with high quality results.  Yet
another use for Imagine.

Date: Sun, 05 Jun 94 01:11:31 -0300
From: [e-mail]

I've been using the HUMANOID data set extensively recently, and really got
tired of having to rotate the eyes to look at the camera every time I moved the
head.  So I thought about it, and came up with a great way to color the eyes
ONCE, and then have the eyes ALWAYS look at the camera no matter how the face
was pointing with no need to ever touch the eyes again!


Solution for Imagine 3.0 users:

Apply the FAKELY texture to the eye, have it affect COLOR only.  Set transition
T to .8, set the back color to -1,, (objects color), set the front color to
0,0,255 (The Iris color).

Apply the FAKELY texture to the eye again, have it affect COLOR only.  Set the
transition T to .95, set the back color to -1,, (objects color), set the front
color to 0,0,0 (The pupil color).

Voila!  Instant eye that will follow and point to the camera without the need
to manually reposition the eye.  Try this on a default sphere.  Render it from
different angles....the eye follows...OOOoooohh!  Scary, eh keedz?

Sculpt4D, and its "Unslice" feature.  Unslice seems to work similar to the
skinning feature in Imagine but does NOT require that each slice be made up of
an equal number of points.  Is there some way Imagine can Unslice?  The
requirement of needing to have equal number of points is too limiting, as the
slices I will be working with will vary in size and shape through out the
series of cross-sections.

 Well actually the disks Amiga 880k, dos 720k are the same. The difference
 comes when they are formated for the respective file systems. If you format
 a 880k disk as a dos disk on the Amiga it turns out as a 720k disk. Even less
 if you were to format it as a Mac disk. So the answer is NO! I use HD's on the
 Amiga they format out at around 1.7 meg(not sure of exact size) and as 1.4meg
 Dos compatable disks. Just another limitation of Dos you have to deal with.
 I have a utility that comes with ADPro that allows you to split binaries
 across several disks. It is supplied for Amiga, DOS,and Mac systems.

         **         OBJECTS TO RAYSHADE FORMAT FOR FREE !        **
         **********************************************************


A new InterNet server is ready to convert your Amiga
Sculpt-4D Objects (.scene) to RayShade (.ray) format.

Note that this is *NOT* a simple dumb filter.Check these out:

* PHONG TRIANGLES SUPPORTED !!!
  Your object will be examined topologically with a rather complex
  algorithm , for the CORRECT ESTIMATION OF THE PHONG NORMALS.
  In simple words: Yes ! You can have smooth triangles converted
  for RayShade.(...this is not a trivial task believe me !).

* SURFACE PROPERTIES ARE SUPPORTED.
  (Glass,Dull,Metal... etc.)

* BAD FACES ELIMINATION.
  Duplicate or degenerate triangles will be removed
  from your object.

* LAMPS AND OBSERVER SUPPORT.



            To use this service follow these simple steps:
            ----------------------------------------------

1) SAVE your object in SCULPT-4D .scene format (NOT SCRIPT).
   Attention : be sure that you saved OBSERVER and at
   least one LAMP , OTHERWISE YOUR OBJECT WILL NOT BE CONVERTED !!!

2) COMPRESS your file via the standard UNIX compress(1) program.

3) UUENCODE(1)  the compressed file.

4) MAIL this file (AND NOTHING ELSE) to:

                [e-mail]

   with Subject:

                   SCULPT_TO_RAY_CONVERT

   BE SURE THAT YOU HAVE A CORRECT SUBJECT OTHERWISE YOUR
   OBJECT WILL NOT BE CONVERTED !!!

This is all...Wait for a while and you will be *automatically*
mailed back your RayShade object.


                    Miscellaneous functions of the server
                    -------------------------------------

- To receive this file send an empty mail to:
  [e-mail] with Subject:CONVERTER_HELP

- Send bug-reports,suggestions,problems etc. to:
  [e-mail] with Subject:CONVERTER_SUGGESTIONS

PLEASE USE THIS SUBJECT LINE OTHERWISE YOUR SUGGESTIONS WILL BE DISCARDED !



                    Some IMPORTANT additional information
                    -------------------------------------

1) Please DO NOT send E-mails greater than 60 Kbytes.

2) If the server is not responding , be patient and DO NOT
   resent again and again the same file.

3) DO NOT include in your mails anything else (human messages ,
   comments , etc ) except the file itself.The conversion is
   done automatically by a computer program.

4) To avoid errors , write a small shell script that will
   automate the process of sending an object.This will
   save you time and effort.

5) The converter software is still beta.

6) I reserve the right to discontinue this service at
   any time.

I sent off a message to the CONVERTER_SUGGESTIONS server asking if he would
consider expanding to other formats (ie Imagine format) and got the following

Its just a good thing I can still type while my foot wedged is in my mouth.
Can anyone help me out by sending him the TDDD (and maybe Lightwave) format

When I was a NewTek dealer, I received a brochure from them which (among other
things) said that the SeaQuest shark was included as a tutorial on Deformation
Maps (kinda like bump maps, but actually deforms the object).

Who told you it should have been in this upgrade?  I can think of lots
of changes/additions that I could say 'should have been' but really
it is more like 'wish it had been, hope it will be nexxt time'.

I'm sure that we'll see more than just that one item for the 100$ too.

If you mean you'd like continuous lines, edges and perfectly smooth shades
of grey that do not consist of halftone dithered patterns, you probably
won't find that in a consumer-grade printer, if anywhere.  Your images
consist of pixels, and each of these pixels will be mapped to multiple
pixels on the paper.  The printer/software is responsible for selecting a
pattern of pixels that best approximates the color of the original image.
The result will not look too impressive when held 10cm from your nose.
    Different printers are capable of different print resolution, so
that you can get finer halftone dither patterns.  300 dpi printers don't
fare so well, but 600 dpi with resolution enhancement are capable of very
tight dither patterns.  Not all software will make use of that, however,
so it comes down to what software you use to convert/print the image.

You can also improve the looks of an image on paper if you render it at
higher resolution.  Printing a 320x200 image will be recognizable at best,
a waste of toner and paper at worst.  Render an image at perhaps 1/2 or 1/3
the spacial resolution of your printed image: 10in x 8in would be 6000x4800
pixels.  Try 2000x1600 to start with, or 3000x2400 to experiment further.
I have had good results using ADPro with a 256 color 1024x768 image on a
600 dpi LJ 4Si.

Subject: PC AutoCAD into Amiga Imagine
Date: Tue, 07 Jun 94 16:03:17 +0100
From: "T.Charalambous" <[e-mail]>

Hi.
Basically, I have a friend who is using AutoCAD to design lighting
rigs, and he wants to animate them. He doesn't have access to any
ray-tracing software.
I want to transfer his PC's AutoCAD DXF format files for use in
Imagine on my Amiga.
What I want to know is: Is there a program that converts DXF ->
Imagine Object Files? Since the DXF file seems to contain all the
details for the `setting of the scene', would I have to import all the
objects in the `scene' separately?
I know my questions seem a bit vague, but I'm fairly new to Imagine,
I am running Imagine v2 on an Amiga A500(!?), with 1Mb Chip, 4Mb Fast,
and W.B. 1.3 - 2.0. I also have an 80Meg HD. I got Imagine3D from the
Amiga Format coverdisk, and have been learning how to use it from
there, and with a bit of trial and error, but I'm getting the hang of
it now.

Thanks,
Tele.

Hi there...

Getting an Amy disk to work in a PC is virtually impossible... myself
and some colleagues have been pluggin vainly away at such a project for
about two yerars and haven't come up with an acceptable kludge without
some nasty programs working at the interrupt level and a small hardware
hack.  Howevrer, if you just use Dos2Dos or even better CrossDOS
(supplied with WB3) then you can dump to 720Kb MS-DOS floppy with
impugnity.  It's a lot less hassle, too, as you just can shove icons
around instead of messing around with DomesDOS's shell... ugh...

All in all, you're better off with the Amiga... B^)

Have fun, Imagineers....

Yes there is a way...  Buy Impulse and recompile the source code with a
DPMI compliant compiler.  Just kidding.  Due to limitations in the DOS
compiler they (Impulse) use, Imagine PC is intolerant of just about all
attempts to run it under a multitasking environment (on the DOS PC's

Curious to know if you--or any--folks have actually confirmed that this
fixed pallet tool works any better in 3.0 than it has in earlier
versions.  It hasn't for me.

    I, too, was tickled to see that ability to set the pallet to a
specified one--but it doesn't work.  At least not consistently.  In a 240
frame anim I've been working on, I do the frames in Imagine, in ram,  have
rend24 save them out and then load them into DPaint4.  (I do this cause
it renders so much faster to ram than to my hd).  I want them in DPaint4
to make a big animbrush, which I use to stamp pix into the vuport of a
ship that's bound for earth. (TotallyOddsome.lha, up on Aminet in the
gfx/anim section).

    Things go fine up till about frame 123, then the pallet starts
swooping all over the place--even though it's still set to one I
specify--and DPaint4 has to start doing its remap thing.  Thank goodness
DP4 is so forgiving and flexible, cause Imagine still plays hell with
pallets.

There is a tutorial on this subject in the July 1990 issue of Amiga World.
The title of the article is "Object Lessons" and is based on Silver, but

A Mobius strip is a piece of paper with one side. You take a long piece of
paper, make it into a loop, but before you tape the two ends together, you
flip one over. If you could walk on one, you would walk on the whole
surface area, because it has only one side.

Well here is the scoop. I supplied NewTek with a shark and scene file
that used displacement mapping to make a whole school of them swim by
the camera. This was included in the early 3.0 releases sent to dealers
but not in the final release. There was another shark that was included
(probably from Amblin) in the later release. Amblin used a chain of bones
rather than displacement mapping to do their shark. The nicest solution
uses a combination of both. But I believe I remember hearing John Gross
(Amblin animator) say that the shark in the seaQuest logo was a real shark
composited in with the CG logo.

Hello all,
    I downloaded a rather nice lens-flare archive (AnimFlare.lha) with
the planet Mars and a starfield included, but they didn't include the 'radial'
texture.  Is this because I own the coverdisk Imagine2.0? If if this is so then
I think it's a shame I'm missing out on this texture! (Could someone mail me
a copy please..)  Also I was going to buy Imagine3.0 (which was announced when
the coverdisk was released but turned out to be 2.9 - a bit of a con!) but when
I saw the price (595 quid) I sighed a bit! Could I (as a humble student) upgrade

for 100 pounds or so?

On a different note, does anyone know where I can find information on GIF, TIFF,

PCX, BMP, etc. file formats, as my good friend needs this and he isn't on
Internet!!

Thank you very much,
            Martin.

Subject: World octovolume
Date: Tue,  7 Jun 94 14:33:39 CDT
From: Allen=[e-mail]

  I guess I wasn't very clear in my last post, comes from being a programmer
I guess!!  I knew about the autosizing of the world size by putting 0,0,0 in
the global actor size bar.  That didn't solve the problem.
  It sounds like I'm running out of memory, which seems wierd considering I
have ten freekin megs, but I'll test it by deleting a few of the objects.  Is
there a watchdog type program that will tell me the memory usages of a
program I'm running in the foreground?  Anyway, didn't 2.0 go ahead and
render a scene even if you ran out of ram, just not rendering random part of
the scene?  Does this mean Impulsed squashed that "feature" or is this
something that happened in 2.0 as well?
  Also, this problem only occurs in trace mode, scanline renders my scene
just fine (except for the lights and shadows, of course).  Are objects stored
in memory differently in trace mode?
  Someone suggested scaling the whole scene down, but my objects have parts
on 'em that give floating point errors if I scale them down much smaller than
they are now.
  I hope I'm doing something wrong, and someone out there knows how to fix
it, 'cause I'd hate to have to modify my objects for a larger scale.

  FYI, the objects in question are: 3x3 km spacestation, 1km long space
freighter, several smaller space craft, a planet created with Essence II, and
a "world sphere" for the stars.  I can delete the star sphere, but I still
get the error about world octovolume too big.  Also, none of the objects
extend beyond the 16000 unit limit.

I uploaded mobicogs.lha to Aminet some time ago.  It's an animated bunch of

You could use the same technique to model a pure strip, and use snapshot to

If your fixed pallet is optimized for a specific scene (say the blue/greens of
planet Earth) and then your animation swung around to a radically different
scene (say the orange/reds of Mars) then this might explain your problem.  Just
a guess.

> [...Printing Q&A...]

  Ok, yes we now understand that we need professional output to get good
looking printed results.  Now I have some problems which some of you might
be able to help with:

  Recently I was commissioned to produce a 3-D masthead for a magazine after
having demonstrated some of Imagine's capabilities on screen.  I had a final
product within a week and everyone was quite satisfied with it.  The
problems began when I had to output the damn thing.  Ok, is it just where I
live or are most service bureaus completely ignorant as to what "raster
graphics" are?  The first one I dealt with was Mac only equipped and they
were insisting that I supply them with a Postscript file.  The final image
having  a resolution like 4800x1800, it was not exactly easy to "fit it
through the door".  I asked if they could support any other raster graphics
format (what's that? they say) like .PCX (What?), JPEG (Huh?) (Like I'm even
going to mention ILBM) or how about TIFF!?: Oh yeah TIFF... nope we can't
use that it can only be used for on screen previews.  Right.  Ok.  So I
generate a POSTSCRIPT file with AdPro.  Jeez!  it's a 30+ Megabyte file!  I
don't have a Syquest drive, so I need to transfer the whole thing on disk
with AdPro's Splitz&Joinz and supply them with Splitz&Joinz.HQX for the MAC.
 Of course they don't understand what to do with an .HQX file and bitch
about me supplying them IBM formatted disks!

   I see that I'm rambling on and making a long story long, so I'll speed up
here.  This particular service bureau spent a whole day on trying to convert
and read my Postscript file and in the end told me it didn't have a
"preview" and that they could not manipulate it.  And they were billing me
for their time! Arrg!  So I went to another bureau which could handle IBM
compatibles.  I first supplied them with a TIFF file.  Corel PAIINT! (the
software they were using) read the file as garbage.  I checked the TIFF file
with another PC software and it was fine.  Corel Paint! also read as garbage
a .PCX file!  It seemed very large files are not read properly by Corel
Paint in those file formats.  Finally the .BMP format worked but it was hell
getting them to use Splitz&Joinz so I finally ZIPped the file (thank God
ZIP's now available on the Amiga!).  Anyhow, they read the file and finally
output it on film, color separated but then I had to generate a black an
white "mask" which also needed to be printed on film so that the printing
bureau could use it to determine what was supposed to be transparent in the
image (around the letters).  I guess that what I would have needed is some
sort of Alpha channel imbedded with the image which TIFF supports, I think,
but they wouldn't have been able to read it anyhow.  That's the short
version of the story.  Needless to say I didn't make any money on this!
 However, it has been printed finally.

  Ok, enough boring you all with my problems.  Anybody have some definite
fullproof tips on how to get professional output from Imagine via service
bureaus?  Hopefully with the above and some helpful tips, other people can
avoid all of this hassle.

  Also: With the dismantling of the Boing archives at wuarchive, does
anybody know where the IML Landfill is moving?

  Maybe an answer to my problems can be found in the IML archives?

Thank you,

p.s.: Sorry to everyone for when I wanted to get onto the IML, I finally
asked everyone on the list how to join.  Recommendation:  Whenever you quote
some text or an extract from the IML, please be sure to mention the
imagine-requests@ address and not the imagine@ address in your quote.  The

You can morph a tacked texture now, by simply using two objects with the
same Lockstate. Just change the texture parameters in the second object.
If, in the future, Impulse makes it possible to do so by having the current
State lock the texture, it will have the advantage of saving disk space by
needing only one copy of the object.

The Tween command in the States menu works pretty well too. It also works

selecting (in group mode) a shoulder axis, and Tweening to another State,
only the arm would be tweened.

I printed a 1680X1188 24bit colour file on a 400dpi colour bubblejet on an A2

out really good. There are about 3 pixels per millimetre. Depends on the size,
a smaller render might look good too. As for a HP laser, the quality will be
related to the contrast between the colours because it can only print B&W, so
if your image has high contrast, it should look good.

From: MiKE <[e-mail]>

Hi all,
I'm relatively new to Imagine (I only just got v3 a week ago, and had v2
through the AF coverdisk) and wish to do a simulation of my thesis project.

One part which I am having trouble modelling is the shock compaction of a
powder.  I won't go into to detail, but I can tell you what I want it to
look like.

A three dimensional shape is seen in x-sect from the side.  For
simplicity, say it is a cube and I am therefore looking at a square.  A
planar shock wave then passes through the material compressing it as it goes.
In ascii:

Now, due to my limited knowledge of the tools within Imagine, does anyone
have a suggestion for the modelling of this event.

Any help is greatly appreciated, as I'd like to have an animation running
for the University open day in 6 weeks time. Hopefully it will spice up a
topic that is very uninteresting to present (and also get some exposure
for the amiga)

I don't know if this is true, thats why I asked. Yes I agree it should be

Hi All!

I've been trying to use the Align to Path and Conform Object to Path
functions, as described on p. 270. (An example could be a tube object,
Aligned and Conforming, becomes a snake as it folllows the path. (Look,
Ma, no bones!) While this works surprisingly well and deforms objects
quite nicely, I have not been able to use them as described in the sidebar.

The sidebar says that you can move the path and leave the object still,
and get the deformation.  The only way I can get it to work is if I move
the object along the path, or if I move both object and path.

Lot's could be done with this, if it works. It sounds like boneless,
stateless deformations in the stage/action editors.

Well, I have done two or three 300 frame anims and it has worked fine for
me..one thing you must do is render a specific frame that has all the
objects, colors in it, if you must load them all into the detail editor
and quickrender them all together, and use this picture as your pallet
pic. If you don't then when you do render it it will pic whatever color
in the pallet pic is closest, and this can still make an anim come out
funny, but the pallet should still stay the same..I didn't think DPaint
would remap while loading in frames of an anim..it will tell you if the
frame uses a different pallet, but you must remap them manually..at least
thats what I always have to do..

I think maybe you are having the problem I mentioned above, but the
pallet is fixs as it should be. But then you could be right as I have
only done a few anims with it and they have seemed to work OK for me, but
not you...?

It is a ribbon with a half twist put into the ends, and then seal them

The manual told me so...page 137 STATES MENU, reads"An object STATE is a
configuration of that object in terms of its surface attributes,
geometry, and the assignments and orientation of its procedural textures
and image maps". Now this could be taken a few ways but I thought the
assingments of textures was more than just what the texture is, but also
what you have set it to...abviously this is not true, but surley you can
see why one might take it this way..especially when below this they
mention a fleck pattern which changes color between STATES..I geuss this
pattern was made from the object faces as this is the only way this could
work from within one STATE object with two states..It will work with two
State objects with different settings so I geuss I will learn to live
with it. But this is a bit misleading...I don't set the rules but I do
hope I still have a right to speek my opinion, which is basically all I was
doing, sorry if it affended you? I wasn't tring to start anything.

From: Mike McCool <[e-mail]>

Hey guy,

    This is in response to your query about how to get a production
house to output your amiga graphics to print.  I can't tell by your
string where you live, but is there a Kinko's within driving distance?

    The kinko's here in Eugene has a Canon color laser printer hooked
to a huge Mac by some interface called Fiery.  It all runs from
PhotoShop, one of the few mac programs capable of wowing an amiga
graphics sig.  Photoshop is great, cause it'll accept AmigaIff's in
24bit.  Only catch is they have to be on msdos formatt'd floppies.  No
biggy, really.

    Realizing that the above paragraph hinges on the availablilty of
a KINKO's, and that if you ain't got one, you're ready to hit the delete
key, here's another way I've managed to get my stuff printed
professionally.  Go into AdPro and invoke that lovely color separation
routine.  Seems like you have options as to how many colors you want,
three or four or five, something like that.

    This worked fabulously for silkscreening t-shirts.  Seems like
again, it was exported to a mac, which actually created the different
color modules needed to create the three-four-five different silkscreen
stencils.  And again, I believe photoshop was the tool, in mac.

    You see what I'm meandering towards, anyway?  You actually have
three-four-five (whatever it is) separate color files for your single
graphic, and they can be fed accordingly into most commercial printers.

    Hopefully someone who's done this more regularly than I will fill
in the specifics, as I realize I may be muddying instead of clarifying.

Subject: Bones & Textures
Date: Wed, 8 Jun 1994 03:33:56 -0700 (PDT)
From: Jeremy White <[e-mail]>

Does anyone know what the unhook function does?  I thought that it might
affect the groups (after selected, the group structure changes -- or does
it?)  After you do a refresh the bone structure is restored.   It never
visually changes.....   Any clue what this does?

I am working on my fish using bones still and have come up yet another
brick wall.  The fish is composed as such ----

     1.)  Main axis - everything is grouped to this.  Especially the
          non-moving (not boned) parts of the fish. (like fins)
     2.)  Body axis - This axis contains the body-mesh of the fish (not
          including head or tail.) This axis has the main axis as a
          parent and bone axes (first one only) as children.
     3.)  Bone axes - This is a chain of axes (5 of them) grouped
          properly for bones.  The first axis has the body axis as a parent.

Ok... My problem.  When I have the main axis selected and choose update
bones, ( and have moved the bones axes) nothing happes.  (ok, no problem,
that object has no bones) so I select the body axis only.  Ok, it works now.
(as I had expected.)

So, I bend the fish and create a state (right tail flip.)  I check the
grouping box only (not the shape box, as the instructions suggest to avoid
adding extra info to the object)  I then animate it using bones anim.
The backbone animates fine, but the body is not updated (it stays unbent.)

Is this because it is a second level group in the object????  Do I have
to click the shape box?? If I click the shape box will the object morphs
linearly!!!!! (see below.)  DOES THIS MEAN THAT WE ARE LIMITED TO HAVING
BONE OBJECTS WITH THE BENDABLE FACES ONLY AS THE ROOT OF OUR OBJECT????

           :-(

-------------------------------------------------------------------------
                     Fix to problem.... Watch for this one....
-------------------------------------------------------------------------

When you morph from between the DEFAULT state to another state (using
bones)  The object will not behave properly.  It might look ok, but it
will morph linearly ( the points will travel in a straight line rather
then bending.  You should create another state (called normal perhaps?)
to morph between.

This is because the shape box is checked in the state requestor.(see
above)

 This is documented in the manual, but only briefly in very small print.

-------------------------------------------------------------------------

Thanks to all the people who have helped me in this first bones effort.
I will donate this object to aminet when done, as it IS a good example of
bones.

with particles.  I have a 70 frame animation I am trying to do that has
letters exploding slowly with the particles effect.  I have fiddled and
tweaked and fiddled some more but no matter what I do at the last frame
there are still particles hanging in the air.  I am using Delayed and
Bounce buttons and have the effect starting at frame 2 going to frame 70.
and the following parameters..
    Travel Distance 450
    Tri Scaling .0001
    Min # rot 0.2
    Max # rot 0.8
    time to terminal H 25

    Min Angle X -60.
    Max Angle X 60.

with non of the wind setting set at all.

    Is there something blatantly obvious that i'm missing out on
here.  During the anim the particles slowly explode out until all the
letters are particles and they start floating down and bounce but at the
end there is too many left "hanging".

    Hopefully I should see 3.0 this week as Nik (IML archivist)

I think I would have used ADPro to process the 24bit file into a 4 color
seperation and then taken or modemed this to a service bureau to be printed
on a linotronic. I think the color seps arw postscript. Another route would
be to output the file from ProPage as a color sep.

Am I missing something here?  Doesn't Imagine 3.0 directly support .DXF
files?  Otherwise, if you are using 2.0 on the Amiga a good program to
convert .DXFs is Pixel 3D Professional from Axiom Software.  I'm not sure

The best way I found to output 3D graphics for print is to use a desktop

floppy disks for the service bureau. The service bureau then need merely
copy your PS file to the printer port to print your artwork....something
not necessarily beyond their small cranial capacity.

To: Imagine

On the Amiga, you can use InterChange Plus to convert between DXF and
Imagine.  It handles many other conversions, too.  It performs a much
better translation than Pixel Pro.  Pixel's manual spends two
sentences explaining its entire DXF translation, while the
InterChange manual has more than twenty pages describing the many
ins-and-outs of handling the often peculiar DXF format.

InterChange for Windows will be released in a few weeks, too.

Hi Dave, welcome to the IML! :-)

Anyway, I found this problem as well a while back... Haven't had the
chance to try 3.0 but it is probably the same. What I did was to scale
the particles down as they moved apart (scaled down to 10% or less of
original) and then, I just made them dissapear in the last few frames by
deleting the object from the last few frames. It looks pretty good if you
do it this way, but it may not be what you need...

>When you morph from between the DEFAULT state to another state (using

As I understand it, you should use the DEFAULT state just to set up the
object, and then create individual states that you are going to morph
between.  For example, you might set up 'flip right' and 'flip left' states
based in DEFAULT but bent accordingly, and a middle 'rest' state that looks
very much like the DEFAULT state.  Then, you'd morph between flip left,
rest, flip right, avoiding using the DEFAULT state.

I mistakenly used the DEFAULT state in a morph and got weird results.  When
I created a new state based on DEFAULT and morphed using that, the morph
worked as expected.  Hope this helps and that I haven't misunderstood :-)

     JFYI, the .DXF importer in Imagine V3.0 Detail Editor is a lot like the
PostScript font importer in the Spline Editor; it only recognizes one type
of .DXF.  .DXF is a lot like PostScript in that it is an UN-standardized
"standard".  The 2D .DXF standard is a standard but 3D .DXF came later and
there are several reasons why it is not a standard.  If you want to find out
more about it, Syndesis (InterchangePlus) will sell you a very detailed
brochure for $10US (last time I checked) explaining what you will be dealing
with when you try to use .DXF.  To make a long story short, the Imagine V3.0
(as well as the Pixel3DPro, InterChangePlus and Caligari) .DXF importers
will ONLY import Release 9 entity objects (maybe Release 12 entities are OK
also, can't check since I don't have AutoCAD) and they won't
recognize/handle layers, polyline, color objects/scenes.  Believe me, I have
messed with this for over a year and a half, and I could fill several pages
about all the things I have tried but I am bored with the whole thing and I
have found a route (not a method or single program but a route) to convert
.DXF to Imagine.
   BTW, both InterChangePlus and Pixel3DPro have some problems with their
Imagine Savers that will result in bad edges and missing faces.  Vertex 2.0
has the best Imagine saver, often saving object attributes (but that is a
whole 'nother story).
  Just so this post is not entirely worthless, the best method I have found
is import the .DXF into 3DStudio, save out as a 3DStudio scene or object,
import into Lightwave as 3DStudio, save out as Lightwave, import into Vertex
2.0, save out as Imagine.  There, easy!

Am I missing something here?  Doesn't Imagine 3.0 directly support .DXF

convert .DXFs is Pixel 3D Professional from Axiom Software.  I'm not sure

No,I've had the same problems with 2.9 at least not locking the pallette

  Motion blurring?  I haven't found it, it's more like image blurring, it
gives  a hazy look to anything sporting a specific color.  It's a
post-processing effect which is applied AFTER the image is rendered, and
therefore has nothing to do with motion.  Different types of forces?  Hey,
this isn't Real 3D 2!  Even Imagine's particles don't obey the laws of
physics.  They just follow some general guidelines on speed and bounciness,
sort of a sophisticated explode effect.  Don't expect them to spin based on
the friction caused by the floor they are hitting.  Inverse kinematics?
 Yes, that's there.  It's part of the cool new "States" animation system
whereby objects can behave like skin (the actual polygons) over bones (the
axis').  the inverse kinematics will let you move "child" bones while being
constrained (?) by it's "parent" bones.  Useful when you get the hang of it.
 Actually although I'm winning about the first two I must admit that this
"States" system is quite nice and one of the most important new feature of
Im3.0 (along with the new textures and spline editor).  You could have hours
of fun with it!

Hope this answers your question?

I just did a set of test with a scene comprising a 'world sphere',camera

Around here, the service bureaus are also Mac based. They can take
postscript (huge), or PageMaker files (merely large).

PageMaker can import graphics in TIFF format and even do some manipulation
before printing the postscript output film. If the bureau has time, they
might let you import your TIFF into a new PM file on their machine. More
likely, you will have to find a friend with a Mac, or go to Kinko's or some
such place that rents Macs with PageMaker by the hour to do the conversion
yourself. The advantage of PageMaker is that you will get crop marks and
color separations, etc automatically. If you can get your hands on Photo
Shop, it can do all sorts of conversions and image manipulation, too.

Now a final caveat, I am new to Imagine, so I have never tried this with
Imagine files from Amiga or PC, but I have done this with TIFF scans
generated on a PC and placed in ad copy created on PM.

DXF is documented.  It is a standard.  Every time they release a new
AutoCAD, they enhance DXF, and there is a new standard.  Just like
TIFF.  Autodesk does this about every two years, since the early 80s.
It wasn't until the late 80s that they had a clear method of
representing something that acted like a polygon.  They are still
limited to 3- and 4-sided polys, though; and there are un-standard
ways that attempt to represent multi-sided polygons.

Why so many problems with DXF?  Any given 3D program usually only
handles a subset of DXF.  Properly handling DXF takes years of
coding.  I know several CAD companies who have people working
full-time on it.  Even Autodesk puts several people on the task.  Any
given 3D program that exports DXF will also choose a certain subset
to represent their 3D data.  There are many ways to do this.
Unfortunately, many of these methods are incompatible with the
subsets that many programs choose to implement on the import side.
There are so many programs that either import or export DXF, and
there's no way to meet all of them.

For InterChange, we carefully document what we handle, exactly, in
terminology that any AutoCAD-head or any 3D-head would understand.

We don't have that offer any longer, the DXF Primer has been folded
into the InterChange manual.  However, I may have posted the Primer
to the net once upon a time, you might want to check the Imagine and
LightWave archives.

You're wrong.  InterChange does recognize and handle layers,
polylines, and pen numbers.  DXF files have no color info, no
hierarchy, and lame object names.  Axiom may be out of business by
now, I have no idea, but their DXF support is much poorer than
InterChange's.  They only handled "entities only 3DFACE" DXFs.
InterChange handles much more than that.

Have you reported this as a bug to Syndesis?  Can you send an example
of a model that results in these bad and missing edges?  This may be
a case of garbage in, garbage out - where did this data come from?

I would suggest using InterChange to go straight from 3DS to Imagine.
This would preserve any sub-objects that 3DS made.  There's no reason
to go through LightWave, the converter that we wrote for NewTek is
several years old compared to the more feature-laden converter in
InterChange.

Yes, Autodesk can write a very good DXF converter.  They wrote the
standard.  If you have a PC, they have a freely distributable DXF to
3DS converter that does not require the $3,000 3D Studio.  We also
include a copy of that on the disks with InterChange when you buy it.

Yo, IML, I don't post often, but I just thought of a feature I would love

to do it in 3.0.

The idea is fairly basic and simple: beveled extrusion.  Say for a font
to have a curved or striaght indented area to make it look *sweet*.

I have tried this in Pixel Pro 3D but we all know the saving problems.
Also, this seemed to create an insane number of triangles.

So, will someone send this to the Imagine 4 Everybody! or whatever? It would
be an AWESOME feature.

Note: I know that I could create multiple sections in the extrude
and perhaps scale x and z down, but this is not exactly what I am looking
for.  I want curved and highly adjustable beveling featurews!!!

So, does anyone have a cool tip for me as I long to make wicked letters
and such????? Help!

yes you do...line the axis so that the Y axis points in the direction you

Subject: service bureaus
Date: Wed, 8 Jun 1994 16:41:28 -0700 (PDT)
From: Mischa David Goldberg-Lockton <[e-mail]>

I went through hell last summer trying to get files from amiga to a
service bureau.

The best solution for reasonably low res at that time was to use
the TIFF saver in adpro and just modem the file in with ZMODEM or something.
Other bureaus seems to all recognize JPG which really should be for video.

Other dudes that had worked on it before said a 44mb mac formatted
syquest was the way to go; but I dont have AMAx and consider this to be
too far to go.

Another option which I havent fully explored is sending your work to an
amiga freindly slide printing service, to make a hires slide for pretty
cheap which should be able to be printed by a photographic press.
(which will be expensive)

As other people said, spltz and jnz is probably a good solution..
ASDG has some of the bombest cross platform tools.

Remember, if you cant convert it directly, convert it more than once...
just like 3d objects.

Do you have Im 2.9 or 3.0?  It's in there.  Look closely in the spline
editor.

Hi Mike,

--but what I've always done to eliminate all particles from the

> of the camera.

   I tried doing this with the thing i'm working on, but the effect
started looking pretty weird.  I had to set the Travel Distance to just
over the whole length of the object.(450)  This object was a bunch of
letters grouped together from the Spline editor.  When they are grouped
together in this way, the effect gives a pretty neat explosiomn starting
from wherever you point the parent axis.

   Now what I would like is to be able to use the gravity, delayed,
bounce etc on an individual object, not just the particles.(ala Real3D I
suppose...)(you know having whole objects bouncing at Z Ground etc ;)
Hopefully this will make it into one of the 1st yearly upgrades, although
I believe it will be the full 3D Spline editor first.

I'm off to play with some more particles....again and again...:)

See Ya

     How well does 3DStudio import .DXF files as well as importing 3DS files to
lightwave?  Can practically any .DXF file be imported into 3DS since the two
programs are from the same company.  Any loss of data during this "AutoCAD to

Did you get Imagine 2.0 from a coverdisk?  I thought both versions were
supplied with the retail package.  I got my copy of Imagine from Amiga
Format and they would supply the FP version if you sent them your original
coverdisk.  I still have the details somewhere if you need them.

Subject: Moving Amiga files <> PC's
Date: Thu, 09 Jun 94 09:26:00 PDT
From: Richard Morris <[e-mail]>

I have to move files regularly back and forth between my Amiga at home and a
486 at work.  I have found the easiest solution to be an AT Bridgeboard.  It
comes with a 1.2mb drive and you can add a 1.44FDD cheaply if you need the
extra space they provide. Then use Backup and Restore (DOS 5 and under) or
MSBackup with DOS 6.x to split large files across multiple floppies.  The
Commodore bridgeboards are dirt cheap now (What else can you do with an AT
these days?)  second-hand and quite a few retailers still seem to have a few
collecting dust out the back which they just want to shift.

your speed is to slow..this is obviuos to me and the terminal H & Z are
to short to let it play all the way threw the full effect.

Date: Thu, 9 Jun 1994 00:12:34 -0400 (EDT)
From: "Mr. Scott Krehbiel; ACS (PC)" <[e-mail]>

Hi Folks
I'm playing with using a foggy blob to simulate a blurry effect
surrounding a glowing object, (like the blue glow that surrounds
the glowing parts of the warp nacelles on the new Enterprise)

It looks absolutely fantastic when looking directly at the fog object,
but around the edges, where you're looking along the rim of my hamburger
patty - shaped fog object, it becomes opaque.  I remember something about
2 fog objects canceling each other out if they overlap, but I couldn't
get this "feature" to work in quickrender.   Is there something about a
feature in globals that could help??

Basically, I have a dull hull-metal grey shape that resembles a hamburger
bun.   I have a bright green shape resembling the hamburger patty (green
since the background is blue - I'll have to change that someday)  and
a larger patty shape that's a green fog object.  The shape of the fog
object is a bit taller than the solid glowing green hamburger patty,
so that it gradually recesses into the bun.   This creates a BEAUTIFUL
glow, as long as you don't look along the rim, where the glow becomes
unconvincing.   Any suggestions you could offer???

By the way, I'm using Imagine 2.0.   Thanks muchly

===================

Hey Nik,

Well, the two easy things it could be first:

The axis will orient the object on the path.  The positive Y axis
points it down the path.

The other easy thing it could be is making sure there are enough
faces for a smooth deform.  It's analogous to extruding to a path--
you need to specify enough sections for it to follow the path.

If it's not something easy like these, we could try something else.

Has anybody gotten this to work with the object still and the path
moving?

     Hey Randy,

     We were talking about the align and conform to path in the Stage
     Editor.  The processes are analogous in some ways, but it's a
     different thing.

     The functions are discussed on p.270 of the manual, and it's
     extremely cool to have a stateless object be deformed by a path
     in the Stage Editor.  Example - a straight tube (no states or
     bones) becomes a wriggling snake by aligning and conforming
     to an "S" shaped path, and moving along it.  It really works.

     I have not been able to get the function described in the sidebar
     to work, however.  That is, the same deformation should take place
     if the object remains stationary in Stage, and the Path moves
     through the object.  You *could* have a flag as a stationary object,
     and make a wavy path move through it, and create a rippling flag.

     I haven't been able to get it to work, however!  Check it out!

 Well, when I was at the WOC in Toronto I talked to a fellow who claimed
 to have made that anim. He was showing the scene file at the time, and
 the wireframe preview looked exactly like the anim on TV. He used 13
 bones to deform a shark object...the object looked like a digitized shark
 model that had been lovingly touched up, but might have been made
 entirely by hand. I can't remember his name. Of course, who knows what

Just keep adding user buttons, they wrap to the next line automatically.

I've found that an AA value of 25 - 35 give they same quality as the old
30, but by lowering the Max Rays to 20 - 50 speeds up the render without
sacrificing to much.

One thing i don't recommend is trying to render a detailed pic with AA set
to zero and Max Rays = 255 .... my 040 took 9 hrs to render 3% ! .... I
reset it to 10 and 100,  and rendered the whole pic in the same time.

From: Leo Hamulczyk <[e-mail]>

To Mike and everyone else at Impulse.

I just received Imagine 3 yesterday and I am pretty pissed off. When
Imagine 2.9 came last year, none of the new textures worked on the
integer version. But I understood that they would work on the integer
version on Imagine 3. But alas, Imagine 3 comes yesterday, finally
arrives in Australia after coming through Amsterdam (it really did, it
had a sticker on it) 10 months after ordering it and I am told on a one
page insert "If you are installing the integer version of the software,
don't bother with the HAZE and LENSFLAR F/X they only work in the
floating point version. Also note that the new textures will not install
if you choose the integer version of Imagine because they only work in
the floating point version. The old textures will be loaded when you
install the integer version." Now WHAT THE HELL DID I BUY IMAGINE 3 FOR?
I am a first year university student, and I cannot afford to buy myself
an accelerator, 32 bit RAM and an FPU. By the time I finish my course
and get a job, Imagine will probably be up to version 25 and anyway, I
don't want to wait a couple of years before I can use the new textures.
I mean what's the problem, how hard is it to write a very short bit of
code so that the new textures will work on integer machines. I mean I
waited 10 months for this and I can't even use half the good stuff. Same
with lensflare and haze. I can put up with the extra time these new
features will take, I'm used to that, but at least they should work. So
come on guys at Impulse, be reasonable. Don't forget that there are some
of us out there who simply cannot afford any upgrades at the moment. I
can barely afford to buy a new wheel for my bike at the moment.

    All the axes in your object heirarchy have to have bone subgroups
    associated to them.  Make a subgroup of all the faces - call is ALL -
    and assign that to all the unused bone subgroups.  Using "check object"
    will help spot unassigned bones.

    As a side note, it sounds like you have the head and fins of the fish
    grouped to the body - if this is the case, you may have trouble keeping
    the head and fins attached.  Bones is ment to be used with contiguous
    objects.  You may want to slice the objects together, delete the
    extraneous parts, join whats left, pick all the points in the seams,
    use snap to grid in point mode with a small grid size, and merge the
    object to get a contiguous object. (those of you out there that have
    humanoid may be able to do the same thing to get the grouped figures
    contiguous.  We all know slice is iffy, so good luck.

>Is this because it is a second level goup in the object????

     yes.

>Do I have to click the shape box??

    If it's boned properly, shape needs only be clicked in the DEFAULT

    the points will move on a straight line path, but the timing

I use InterChange Plus Ver 3.0 for this.  It does a good job too, on the
whole.  If you have trouble converting DXF to Imagine with it (I sometime
get strange triangles lancing out in all directions), converting to Turbo
Silver 3.0 format usually does the trick in such cases.

I've been converting AutoCAD houses using it and it keeps all the

um...  Thats the anti-aliasing, man.  If you pix look blurry - it means
your pixels are too big - render at a higher resolution to see what I mean.
 - And - What makes you think its post processed ?

Motion blur isn't in 3.0.  We couldn't find a way to do motion blur that
could get done in a reasonable amount of time.  Some renderers just render
a bunch of interum frames and composite them into something that looks
sort of like motion blur, but if you look closely you can usually see
artifacting - This isn't good enough.  We've gt some ideas, but it won't
be put in until we can do it in a way that won't quadruple rendering
times and won't look digital.

People are doing motion blur with Imagine using this image compositing
method.  It works well for stills, but is too time/labor intensive for
animations.  I suppose we could have put this compositing into Imagine
and called it "Motion blur," but it isn't true motion blur and we didn't
think it fair to call it so.

My guess is it's garbage in - garbage out.  I don't know what modeler
people are using to create these flakey models.  The bad models seem
to be primarily public domain stuff - could have been exported or
converted using cheezy converters from something like POV, DKB, or
any of a zillion DXF automatic object creation tools.

Imagine should read any DXF with ENTITIES/3DFACE data - all colors and sub-
object info will be lost though.  I haven't used 3DS, but rather than
saving DXF scenes, save just the object(s) - I don't know what Imagine does
with the scene info.

Sorry to be contradictory, but I thought I should hit this again to
avoid any confusion.  This FX isn't documented well, if at all, so
I hope this help:

"Speed" is used to control how fast an object comes apart when using a
"delayed" particle explode.  This is the speed the object comes apart, not
how fast the particles move.

The "Terminal H and Z" are a bit tougher.  The particles, sort of,
accelerate away from the exploding object.  These params control how many
frames the particles will be accelerating through.

Again, I suggest cranking up the gravity.  This way the particles will fall
faster and stick to the ground sooner.

Many of these parameters and the effects they have on the particle motion are
inter-related.  This really complicates explaining this FX - If I can come
up with a representative equation of what's going on (if I find the time and
motivation that is) I'll post it.

You may not like this, but I gotta suggest getting 3.0.  There is a
texture called Ghost that makes the edges of fog objects dissapear.
Beyond that - sorry can't help.

I sort of agree, but I am studying at uni so I don't have as much time to use
my computer as I used to. I could leave something rendering for a couple of
days and come back to see it finished. I have done a couple of half-day
renders even one 3.5 day render (all single pictures) so I have no problem
with the time. When I finally get out of uni I'll get something faster but
that's another 2.5 years, and in the mean time I want to have something to do.

Hmmm? well I think the problem with the fog getting opaque is because the
fog is denser at the edges, if you think about it this is normal because
you are actually applying it to an object, and looking at the edge there
would be more faces in this area..I don't really know how to explain
this, but hopefully you understand what I mean...anyways perhaps if you
apply the Radial Texture to this object and set the filters to something
like 200,200,200 ( you'lle probably have to experiment with this ) and
set the color to whatever your fog is and size it in the Z axis as well
as move it so that is fits your burger better, this will give you the
effect you are looking for.. Hope it help? let me know what happens..

Good luck!  I've been asking the same question for six months.  MPEG is a

Mike, I went and tried it and got it to work just fine..it is really cool.

Basically I don't think it will work with all paths but it might with
some calculations of x,y and z, heres how I did get it to work...

Make a defualt plane and Align the X axis to 90 in the Tranformation
Requester, make sure you have Axis Only set when you do this ,
then make a path, say with 10 axis points, move every other points Z axis
up to make some smooth curves, then save these objects seperatley,
make a test project and go to the Action Editor and set it to 25 frames
load in the objects... set the plane to follow the path. Save this and go
to the Stage, now set your camera view on and position it so you can see
the plane object, Now heres one of the important parts hit RghtAmiga-P to
see what your paths length is, write it down and go to frame 25 of the
animation RghtAmiga-C. Now select the path and use RghtAmiga-T to get to
the Tranformation Requester, click position and set Y to - (minus) whatever
the number you wrote down is, hit return then OK. Now hit RghtAmiga-7 to
save the position as with Position Bar. OK we're almost done, Save this
and go back to the Action Editor and select the paths NEW Position
timeline bar and set it to Discontinuous Knots, click OK, now select the
plane and set its Alignment to Conform Object to Path, click OK. If this
were a grouped object you would use Conform Group to Path...Now save this
and go to the Stage and Use Make in the Animate Menu to make a preview
animation...Wala! a Flag Waving!

Can I use the axis that the faces are associated with as a bone

It doesn't seem to be a problem...  I just move the grouping for each

FPU's are not that expensive, and unfortunately, 3d rendering, while now

Hello again,
  In experimenting with the world octovolume error I've been having, I think
I've found a bug in the stage editor...
  I started with a 15000 unit radius sphere, a light source and the camera
inside the sphere, and tried to quick-render the scene in Trace mode.  I got
the world octovolume error as expected (Any help on this IMPLUSE?) but here's
where it gets weird.  I gradually reduced the radius of the sphere, keeping the

light and camera inside the sphere, and got down to about 1000 unit radius when

I decided something was wrong.  I deleted the sphere altogether, then tried to
quick-render, and got the same world octovolume error!!!
  Let me restate this: after starting with a huge sphere that generated an
error, deleting the sphere and having a scene with one light, the camera, and
NOTHING ELSE, I was getting a world octovolume too large error!!  I had to
leave the stage editor and go back to clear it up.

  Back to the volume error: I turned GigaMem on to see if it worked with 3.0
better than it did with 2.0 and the new memory menu option shows all 25 megs of

memory free!  I'm starting to think the "octovolume" is a hardcoded limitation
of Imagine, not a memory problem!!  Why does this only show up in Trace mode??

I'm putting the spacestation animation on a back shelf until I get this figured

out.  A nice, SMALL, still life sounds pretty good right now!

   How about a nice game of chess?   -Rico / [e-mail]

This doesn't really solve the problem completely. I've had the constant
way up (like 20+) and some particles will still stay. What will happen
though is that the majority will drop really quickly.The only way that
seems to work is to scale the particles down to nothing.

Hiya Martin. Imagine 3.0 is an awesome piece of software. Even so, there
are a few bugs and shortcomings in it, and Impulse seems to be responsive
to these... They've already issued a patch file that fixed a bug, and
there may well be more in the future.

They advertize a new support program, called CONSTANT UPDATE, which will
allow you to get at LEAST 4 updates of the program per year, for a $100 annual
fee. This is similar to programs offered by other software companies. I've
talked to Mike Halverson at Impulse, and I think that the CONSTANT UPDATE
program is a sound one. I'm planning on signing up next month.

However, there has been no discussion about bug fixes (to which all users
are entitled, even if they don't do the CONSTANT UPDATE) and new features
(only for those in the CONSTANT UPDATE program). I'm curious about
that... But, since I am planning on doing the CONSTANT UPDATE, I am not
as curious as someone who may NOT be doing that might be...

As to the discussions here on the IML - Impulse does monitor this group,
and have been very responsive and visable in the IML. So, as Impulse has
said before, they ARE listening...

BUT, if you want to do it in Imagine....BTW, I think this may be in the FAQ.

---------begin old post include ----------------
Sure I'll tell.  I took this idea from someones suggestion on how to make one
of those Frankenstien lab things where the spark runs up the two poles.  Here
is that quote:

3. I used Essence to make an electrical arc between two rods, like
something out of Frankenstien's lab.  Start with a plane with 255
R,G,B on Color and a light blue (or whatever color you want the arc)
in Filter.  Then use Ringfract (with the cylinder pointing out of the
plane) with a color of 0 on R,G,B and turn off the filter and reflect
values.  Put the axis of Ringfract in the middle of the bottom edge of
the plane.  Now use Swapcrf to swap the color and filter values.  Now
when rendered, there should be something similar to an electrical arc
(or maybe some sort of plasma).  To have the arc grow, rotate the
Ringfract axis up or down so that the plane and cylinder do not
intersect at 90 degrees.  If you animate this it looks like the arc
gets taller until the arc breaks (i.e. the plane no longer intersects
Ringfract's cylinder in a curve, but instead in two lines).

--from Peter Garza --

instead of using Ringfract(from Essence, BTW) I used Bandfract(also from
Essence).  It allowed a straight line.  The high and low start parameters
indicate the thickness of your lightning.  You'll have to play with this.
I used 40 for low 45 for high.  The other high and low I set to 5.  It
seemed to make the lightning really jaggie if I set these to the same number
as the width(I think).  The other params I left on default.  In Swapcrf,
set everything to 0 except Color -> N Filter, Filter -> N Color and
Reflect -> N Reflect which should be 100.

To animate it, I morphed from a thin version of this plane to a full sized
version of this plane.  I also rotated my texture axis around Z in order to
get the lightning to jiggle and change as its being sent from the source.

I played with this in low res with just the plane and a light source until
I got the effect I wanted.  Then I added my Ti-fighter(from Star Wars) and
had it shoot a bolt of lightning/plasma ray across the sky.  Cool!

Hey, thats me ^^^^ :)

So, you can use several planes to achieve several bolts of electricity, or
paint it in after its rendered.

Any other ideas?

From: [e-mail] (Thomas Setzer)

I would like to create a shield effect like the one in the BattleJPG
from /pub/aminet/pix/guard (I think thats where it is).  Anyone have
any luck animating these?  Here are some previous posts about the subject.
Any luck with this Christopher?

----------begin include--------
From: [e-mail]

         I've got a 500 frame animation of a fighter (the sci-fi variety)
firing upon another ship. I have a shield appearing (a primative sphere)
when the blasts hit it (mostly transparent with blobf for texture). Problems
arise when I try to use shellturb to show the blast hitting a portion of the
shield. I want to create a ring sweeping from the impact point to the
opposite side of the sphere. Nothing seems to show up on the damned sphere!
I tried using a very narrow "solid" texture and have it morph from one side
of the sphere to the other, no go, it just turned the whole shield red ;-(.
If anyone has any suggestions, I'd appreciate it......

From: Peter Garza <[e-mail]>

        I guess I'll try my 2 cents worth.  How about using bandturb
or bandfract to do the ring.  You could then morph the Low and High
Trans Start or morph the position of the texture axis to have the ring
move across the sphere.  From what it sounds like, this might be what
you want.

There is a really nice modeller on aminet called FreeForm3D that models
using splines. It can decompose the spline surface to triangles and
save them as an Imagine object if you register the software. I find it
extremely easy to use and the example Imagine object worked fine. It
can also load/save R3D objects. I think the registration fee was US
$60.00 but I am not sure.

Hey Nik,

    The return string is weird here, so if you get this, my faith is
restored. The user button query of yours is addressed in the preferences
section.

    Another IML'ster pointed out what a fabulous feature preferences
was, and he was right.  You can now have two rows of user buttons.  And
if you abbreviate, as I do, you can just about hang your whole pulldown
menu across the bottom as buttons.  It is GREAT.

    You asked about anti-aliasing, too.  I haven't gotten any
conclusive speedups so far.  Hopefully someone else has optimized this
function for best reduction of jaggies with least increase in rendering
times.

    Another of you Southern Star droids posted a couple of weeks
ago about anti-aliasing and rays, and said that with an A A setting of
10, he could still get reduced jaggies with no particular increase in
rendering times if he lowered the maximum number of Rays to 30.  I
haven't had time to confirm this, but give it a shot and see if it helps.

    (And btw, thanks, to Dave Wickard, for salvaging this post.  It
bounced off Pluto, and would have been lost in e-space, if you hadn't
snagged it and sent it back to me).

Scanline modes?  Why not Trace as well?  At least if we were doing some

Ok here's the Update Policy deal as described in Impulse Graphics World
newsletter (which I guess you are not receiving yet):

     1 year of updates = $100 US

   Can be purchased at the beginning of the year, where they will be sending
you small (?) regular (??) updates of new features(/fixes) and additions.
 Or, can be purchased at the end of the year (same price) in one package.

And about the receiving the constructive criticism (complaints), apparently
they do, on a regular basis.  They will even be helpful and address
problems/questions directly on the IML.

Although this is not as good as a built in function you can
composite frames to achieve the same result.  If you have an animation
you want to do this to, start you anim a frame or 2 or 3 early.  Then for
frame 3 you would composite frame 2 with it at 25% and frame 1 at 10%.
Play with your percentages.

This works okay, don't yell at me if it's to obvious or your point of
view is moving or you don't want it applied to all moving objects.

I previously said, "It would be great if motion blur could be
implemented for scanline modes!".  Of course this is in addition to
Trace as well - I often get good enough results for my projects just
using scanline modes, and since I'm tracing on an A1000 (with Lucas/Francis
hack to include 020 and 881 to 16 MHz) speed is of the essence.

My point is, I wouldn't want to restrict Motion Blur to just Trace mode.

     Wow, that quote was from awhile ago. Yes I got it figured out and it
worked well (so well it was used for a live performance ;-). The actual
project is somewhere on a floppy backup and I'll cough it up if anyone
REALLY needs it. Take some time to fiddle with ringfract or shellturb
(basically anything energy-like and morphable) on a primative sphere. I
believe I had to use one of the "swap" textures to make it stick to a
transparent surface but it WAS a long time ago. I'll de-archive the
project and take a look at it.

Nik,

Did you try the settings I gave you, what did they do..did you set the
Min Angle from Z to 0, I believe you had it at 20 and this maybe keeping
your particles 20 units from the ground at the end of the effect... and
why they stay hanging...the reason there falling so fast is because you
have the Terminal Z Velocity at 30 or something like that set it to the
amount of frames the effect last..I believe it was 93 or something.. this
should slow them down.. same goes for Terminal H Velocity this will slow
the expantion of the Particles on the Horizontal axis's.. Did you get see
my last message repling to this, What happen when you tried it?

This may have been me, and I'm glad to see that it influenced someone to
go and check it out..It really is one of the most user friendly parts of
Imagine and from what I have seen Impulse put in some Newsletters, one of
the least used..Glad you have discoverd it! As you use it more you can
refine your working enviroment to help in the speed of developement of
objects and animations.. Though I don't now if having everything in the
Menus is actually neccesary, there are many Function keys you can set as
well, and I personally find them faster than the gadgets for some things.
and don't forget to memorize all the Hot Keys as well, by doing things
this way you can keep you gadgets less clutered and easier to find, which
will also help you speed up developement..Just a sugestion, if you like
it the way you have it then this is probably fine for you...but as you
use Prefs more and learn the many HotKeys you may find you agree with me?

*********************************************************************
; This is an example piece of code for coded textures on imagine2
; on the Amiga.
;
; It might work on imagine3, if anyone can test it then please let
; me know.
;
; I have done this texture in 68000 because the interfacing would
; be a little tricky in C. Imagine starts up the texture as an
; executable (LoadSegment) and then passes some initialisation
; stuff on the stack - the texture must respond with the correct
; data block returned in d0 or zero for fail. You need to set up
; either the FP code or the integer code depending on the version
; of imagine running: Please code BOTH versions if you release any
; textures otherwise you will find them crashing on other machines!
;
; Imagine passes the x,y and z coord relative to the objects axis
; to the texture for each intersection point, we then can alter the
; objects colour,reflect and filter or leave them as the users base
; settings.
;
; You can alter which parameters are requested in the texture setup
; by altering the text below and then setting the colselect data
; to tell imagine which numbers are to be displayed as red,green and
; blue colours in the sample box.
;
; axispar sets the default axis for the texture mapping, I have set
; them to be aligned with the worlds axis, if you change these then
; make sure that the axis size is nearly 1 (root(x^2+y^2+z^2)=1).
;
; Setting the objpar will alter the default numbers for the objects
; parameters on the setup screen, set these to appropriate values
; for your texture.
;
; The integer math format is number/65536 eg 1.0=65536 etc.
; When reading the colour information from the texture parameters
; always divide them by 256 because imagine uses colours in the range
; of 0-1 red, 0-1 green and 0-1 blue.
;
;
; For more information or comments contact me:
;
;            [e-mail]
;
;
; N.B. Ive been a bit lazy - the integer version of this texture uses
; 68020 and above code! If you want me to change this then mail me.
;
; The examples in this code are mixed! The FP code example produces a
; mandelbrot set rendered against the final orbital position of points
; not inside the set. I am using a log palette and the red green and
; blue scale control the amount of palette tinge.
; The integer example is a bog standard chequer board.
;
; To use this file assemble it on Devpac or any other 68000 series
; assembler (You may need to make changes for some assemblers). Don't
; forget to select FPU and 68020 or above. Assemble the file to disk
; and load it into Imagine as a texture. Following this text is the

Hi Randy,
    I was the one with the particles prob.  I used the settings today
(been sick) and they seemed to work better by the end of the last frame.
there was still a couple of particles still there, but the using the
scaling thing in the requester made them disappear.

    Thanks for the numbers.  I received 3.0 on Friday and have been
reading a bit more about the effect now.  Still needs to have more info
on it I think...


see ya

OK, sorry to hear they did'nt solve your problem..I did a similar
animation and it worked fine for me, the particles bonce twice or was
three times and all landed on the ground fine..Hmmm? Are you sure the
distance to the ground matches the distance they are to fall. Doesn't seem
like this is your problem as this, I would think would be abvious.

>From the settings you had;

Travel Distance 450
Ground          -87.4961

your actual object would have to be at global Z 362.5039. Is this were
you have it? If not this maybe the problem..

Did you try 0 in the Min Angle from Z?

I know you said that scaling them made them disapear, and if thats good
enough for you then thats cool. But If you want them to stay on the ground
after they fall, then this will not do. Just trying to figure out why I
got it to work OK and these figures did'nt help you. Hmmm?

Yes, they are a bit unpredictable, and take alot of testing to get the
disired effect some times.

Good Luck!

Hello!!

Just got my copy of Imagine 3.0 for the PC, and just got
hooked to this list.

When i use the Particle Generator, 30 % of the times it
crashes my PC, WHY ???(Yeah, i know buy an Amiga, well i just sold my old
2000 a year back :)
I think it crash when i use Random Particles and try to change the size
of the particle to under 1.

What do i do now.

Are there a fix for this prob, or will i just have to ignore it??
(Its  not a big problem right now, but might give me some gray hairs
in the future)

I guessed that much, but it would be nice if imagine just

Not just "You fool, i just crashed you computer:)".

Well it would be nice, would it :)

Subject: State
Date: Sun, 12 Jun 1994 23:43:01 -0400 (EDT)
From: "ElectroSURFER)))))))>" <[e-mail]>

My understanding of using states in the stage editor is as follows:

we have three states: 1. wingleveled
                      2. wingup
                      3. wingdown.




1. Load the object in into frame 1 of 33 for example.
2. Info requester pops up.  I select state wingleveled.
3. In action editor I change object time bar to five
4. select add and add same object on 6-11. requester pops up, select wingup
5. add 12-17 in time line, then select state wingleveled
6. add 22-27 in time line, then select state wingdown
7. add 28-33 in time line, then select state wingleveled

Is this the correct use of states.

The only thing that the manual mentions concerning the use of states in
animation is on page 244.  Actually there is another area, the detail
editor, but there your not required to reload the object.

If the above assumption of the usage of the states with animation is
correct still leave a message explaining your version of it's usage.

Thank You

Subject: Path Deforms in Stage
Date: Mon, 13 Jun 94 00:16:05 EST
From: [e-mail] (Mike Tucibat)

 Hey Randy!

Nice Solution!

The problem, of course, was:
=========
> That is, the same deformation should take place
> if the object remains stationary in Stage, and the Path moves
> through the object.  You *could* have a flag as a stationary object,
> and make a wavy path move through it, and create a rippling flag.
>
     (Details of solution omitted for brevity...)
=========

As the path moves in a -Y direction, the plane moves +Y. Kinda like a
treadmill.  Nice!

I wonder if you checked for a small change in the end position of your
plane, though.  For a while, I kept getting one.

Like you found, to hold the plane's position, the distance it travels
must equal the distance between the endpoints of the path.  The "length
of path" in Stage is not that distance, however, but rather the length
of the curved path. I had to go to Detail to make a path of known
distance between endpoints, and use that distance, to get it "stationary."

I *guess* this is what p. 270 sidebar means.  Although the object *is*
moving, it's not too apparent. It doesn't seem to work without the object
following the path, and that creates change in position.  And even though
the start and endpoints are the same, using the distance I describe, the
plane still changes position as it begins to follow the path-- it just
ends up back where it started. I also checked and this was possible with
2.9, also.

But, anyway, cool effect!  Thanks for the input!

This does not seem right unless you want the object to remain perfectly
still for the first 5 frames.  Set the first object to 1-1 (wingleveled).
Then set the second object for 2-6 (wingup)  In frames 2-6 the wings will
start at leveled, and by frame 6, be completely up.

TO all imagine fans,
            Does anyone know when these updates are coming out, i.e
building up  to Imagine4.0 (or just 3.9 will do!)?  As I realized that the
promised beta-spline objects will take up far less disk space (a sphere may
contain 400 faces, whereas a geometric primative sphere may only have a few
parameters) and also the wireframe view would look less cluttered.  I think
we owe it to ourselves, my good friends, to make sure these important issues
are addressed!    Is this too much to ask??

Hi ...

Can i get Imagine 3.0 to think that an object is solid.
(A nice glass cube)

And can i make a drill efx, putting a small sphere inside the cube??

Hi fellow imagineers!

First excuse me wasting bandwidth, but it may be of concern for all
those working on different platforms.

I want to transfer data from PC to Amiga with a Streamer-Tape
(Typ 6150) (The big cartridges).

The Problem: I need a programm which is existent on both platforms
and can write on a streamer-device.

Any help appreciated,
  Peter

Subject:  genlock objects / Matte Painting
Date:  Mon, 13 Jun 1994 10:01:19 -0400
From: "rob (r.d.) hounsell" <[e-mail]>

Folks,

  I've discovered (perhaps belatedly) that although the attributes requestor
screen capture printed in the Im3.0 manual has a "genlock" button, the manual
doesn't mention it and it doesn't exist in the requestor on my screen. In fact,
I don't see anything about genlock in the index.

  So, how do I accomplish what I believe is called matte painting? I have a
scene in which there is only a small area that is animated, while the rest is
static. To save rendering time (2.5 hours / frame) I want to render the whole
screen for the first frame just once, and have the area that the action takes
place in genlocked (i.e. black); there is an object that masks it nicely. Then,
I would render the rest of the frames using only the objects that are moving by
using layers in the stage editor (so I can get the right reflections on the
animated objects - at least I think that's the way it works...) and then
composite them in ADPro. (sounds like a good REXX application...)

  Since I don't have the option of using a genlock object, I could make it
bright and force the colour to be black, but then (according to "Understanding
Imagine 2.0) that would cause reflections of the object in the matte scene to be

black rather than the real colour.

  I can't just render the mask object alone and use it as an alpha channel
because it is clipped by other objects.  The only thing I can think of is to
have a copy of the scene in which objects that clip the mask object are black
and the mask object is white, and then render it in colour shaded mode to get an

alpha channel mask.  I suppose touching up a copy of the overall scene in DPaint

would work, but I was hoping that there was a genlock workaround.

Thx
Rob

I called Impulse last week, to ask about the $100 interim upgrade program.  What

I was told was to hold off on buying it until the first upgrade is available.  I

was also told the first upgrade would probably be a new 3d spline editor to go
with or replace the current 2d spline editor in 3.0.  The person I talked to sai

it would probably be a month or two before this was ready.

 I am not sure if Imagine can do what you want. If you set the Genlock
 function I think it only makes the background color zero, an does not
 take in consideration the object. The problem is that if color zero
 is used in the rendered object it is transparant also. What you could do
 is move the pic into dpaint alter the pallete to make color zero really
 stand out, fill the occurances of color zero in the pic with another color
 and then rest color zero to it's original setting.

Anybody have an idea as to what sort of resolutions are used in computer

the ones playing at a theatre near you.  I realize most computer generated
imagery is often mixed in with live footage or traditional animation and
therefore don't take up the whole screen, but what kind of resolution does
the industry currently use to generate frames that fill the screen without
having noticeable pixelization. Regardless of software/hardware used.

From: [e-mail] (Peter Jennings)

I recently purchased the book, 3D Modeling Lab with its accompanying copy
of Imagine 2.0 for the PC. I am finding the software to be extremely
fragile, regularly collapsing points together, hanging and crashing to the
"abnormal termination, please call Impulse" message.

I know I didn't pay much for this copy, so I don't expect any support from
Impulse on it, but I have some questions.

Is there a bug fix version of this program around that doesn't crash quite
so often? Is anyone using this version of the program successfully?

Is there a reference manual or equivalent for the features which are not
discussed in the accompanying book?

All I was after when I purchased the book was the forms editor portion of
the program in order to create simple objects for use in stereograms. Is
there an inexpensive PC or Mac program that anyone knows of with a similar
interface for editing 3D shapes. I like the way Imagine lets me create
objects, but I just wish it would keep running.

Ya, I did notice this but thought if I could get you aimed in the right
direction you could get it to work properly with some more testing. I
did'nt have the time to get it perfect, and just wanted to see if I could
get close to what the manual says.

Great! I geuss I should have checked the path there instead of in the
Stage, but I just wanted to get things in the Stage and start
testing them out so that I could report something to you before I
had to go to sleep. Thanks for figuring out the small glitch in it,
Looks like it was a good team effort..hehehehe

Ya, I'm sure it is as there was no other way I could get it to work, and
it does a fine job of it. Though it maybe a bit limited to certain types
of paths it is a good effect to have in our arsenal.

I would greatly appreciate it if someone would be able to

  What has me frustrated is that the 2 options are still in the
preferences but there seems to be now way to activate it...bit of a

    What genlock does is as follows:

    Suppose you have a brushmap of a logo or something and you want to
'decal' it onto your object.  ie: perhaps you have a name and you want to
make it look stenciled on a wood crate object.

    Normally you would make 2 objects, the crate and the decal, and for
the decal object 2 maps.  A color map and a filter map.

    However, genlock will take color 0 of the brushmap and leave the
object at that point untouched.  Thus you can directly map the brush onto
the box with any color you want, so long as the bkg section is color 0.

    I don't think this helps with what you want to do.

Sorry to answer so late I just got back from being sick. I am finally done

anyway I have not used the parameters you are describing. What I have done
in the past is just decrease the amount of time in the action editor to
make an increase in speed then more time to slow it down. In fact I usually
use Aworks for my final anim because I can then add music and fluctuate the
speed on a frame by frame basis, overlay text, and access imagefx tools and
macros to modify to my hearts content.....

        I will check out velscal when I get back tonight and see what more
I can find out.

From: Allen=[e-mail]

  I was thinking about the recent posts about how some particles were left
hanging in the air at the end of an animation.  Could it be that the
animation needed more frames in which to finish the effect?  If you give the
special effect parameters that would require, say, 100 frames to complete,
and then tell Imagine to render 80 frames, some of the particles would be
hanging in mid flight at the 80th frame.
  I've only played with particles once (the tutorial in the manual) but I
don't remember there being a TIME parameter like in animated textures, where
you can specify that the texture animates from 0 to 1 in however many frames
you set for it in the action editor.  If I remember right, special effects
don't work the same, frame-wise.
  Now that I think about it though, there IS a parameter or two that accept
values as a number of frames, but I think it was distance traveled or wind
speed or something along those lines; nothing for the entire special effect
itself.
  Can anyone shed more light on this?  If I'm wrong, sorry for waisting band-
width.

Does Imagine3.0 allow you to render a portion of an image, like Real3D does?
If it does it would be nice if you only changed something little and you only
wanted to render that change, i.e a user-defined box or somthing.

On a different note, I like the sound of all the peripherals for Imagine which
will be released e.g The Object Digitizer and a few months ago I had the idea
of transforming a pair of stereoscopic images into a 3D scene using image
processing.  I realise this does have it's problems but does anyone have
some useful information which would help me?

Thank you all,

   I have also found the confetti texture unsuitable for animation.
 Actually, I don't think the Imagine starfield is that bad for animation but
it would be better if there were some option for different star sizes,
intensities and colors.
  This has been a topic on the IML off and on for the past couple years that
I know of (from reading the IML archives).  Has anybody actually been able
to put together a good, animatable starfield, especially one that you can
fly through ala Star Trek Next Generation?  I tried Steve Worley's
suggestion in Understanding Imagine, which would probably be OK if you had
all the stars at a fixed distance away from the foreground object but
doesn't really work if the stars are at varying distances and the object is
traveling amongst the stars.  If the basic star is a fixed size and copied
numerous times, and moved off into the distance, they tend to get smaller
and less bright which is what would be expected.
   I think the primary problem is that trying to achieve a real-universe
effect is not achievable with this level of a program and desktop computer
without resorting to some artistic license.  If everything is modeled to
scale, the program's limitations are exceeded on one end of the scale or the
other.  The maximum octvolume allowed by Imagine is about 16,000 units.  If
we place ourselves at the center of this "universe", and use real life
dimensions and say that the radius to this limit is where the closest star
to us would be (Alpha Proxima ~ 4 light years), then scale that 8000 units
to be 4 light years ((6 x10E12 miles/ly X 4 ly ) / 8000 units), we get
approximately 3x10E9 or 3 billion miles per Imagine unit (sorry for the
English dimensional units).  And this is just to model the distance from
Earth to the nearest star (other than our own star).  So, if we model a
1-mile long starship, it would end up being 1/ 3 billionth of an Imagine
unit long.  If you try to model all the stars within a 40 light year radius,
then the dimensional scales become even larger.
   The bottom line to all this is that no one from Earth (as far as I know)
has actually achieved light speed or faster-than-light-speed travel yet and
traveled among the stars.  So all the flying starfield, doppler-compression,
dimensional compression/expansion effects we are so familiar with are pure
fantasy.  And 3D modeling/animation tools are perfect for portraying these
fantasies.  These fantasies tend to be visually stimulating but
scientifically inaccurate.  For example, the flying starfield effect would
require one to be traveling at many times the speed of light, to have stars
whizzing by you, which would require light doppler compression to go well
past the blue end of the spectrum, which would probably mean that they would
not be visible at all to the bandwidth of the human eye.
  So, to achieve the desired visually stimulating effects, we have to
develop work-arounds.  I think the best starfield would consist of multiple
"shells" of different size "star" objects.  The "shell" furthest out would
consist of the largest star objects, then progressively become smaller as
they got closer to the center.  In the center area, there would be a dense
cluster of smaller star objects to achieve the flying starfield effect.
 This does work as I have been working on a simple version (limited number
of stars) but the redraw times get to be really long.  So, to develop a
convincing  model is going to take awhile.  If somebody has already done
this, and would be willing to share the model, it would be appreciated.

Yes.  It's called 'set zone'.  You can render any portion of the
perspective window.  Once set, can also be used in the project editor.

Will the object be solid, or will i just end up with a glass shell cube
with a glass shell sphere inside with air in rest of the space.
Well more like vacum(?), i want glass not vacum(?).

> >How do I do Star Fields (animatable)?

Here's how I've done this a few times in the past.  It works pretty well,
with only one drawback, but that should be fixed with Im30.

- Get an IFF of a starfield.  I used Distant Suns.  If anyone wants, I can
upload the pics I've used (if I still have them).

- Create a sphere primative.  You can use a few less sections than the
defaults, but not too many less.

- In Pick Points mode, chop off all the bottom points, you you only have
a dome.

OLD WAY:

- Map the IFF onto the dome, using the default alignment.

NEW WAY:  (untested)

- Make a state called DEFAULT

- Scale the object so it's totally flat.

- Make this a state called FLAT.

- Map the IFF onto the flat dome, but realign it from above.

- Lock the state to FLAT

- Reset to DEFAULT state

BOTH WAYS (continued):

- Make the object bright and phong shaded.

Voila!

Put this object in your scene and scale it so it surrounds everything.
If you stars both above and below (I've only used this for the sky, not
space), but another one (with a different IFF) below.

In the OLD WAY, you can only look at parts of the sphere, because the
stars will be smeared at the edges (although I worked around this by
pulling around some of the points, but it's still somewhat limiting).  Now
with brush tacking, this shouldn't be a problem.

This has worked great for me, and even allows for 'real' stars.  I can
place my favorite constellations wherever I want them.  Distant suns does
a good job.  With only a 4-16 color IFF, you get different brightnesses
and sizes, very realistic.


For 'warp speed' effects of stars whizzing by, try this.

- Open DPaint if 4 or 8 colors, lo-res or interlace, not hi-res
(experiment.  It all depends on how far and how long you want your
whizzing stars)

- Make a ten frame (or 20 or 30) animation.

- Create a gradient from pure white to pure black.

- Make a small brush filled with that gradient, like this: (0=black, 7=white)

777777
666666
555555
555555
333333
333333
333333
111111
111111
111111
111111
111111
111111

It doesn't need to be this big, but it could be, again it depends.

- Make a full screen wide line from this brush, i.e.

*
777777777777777777777777777777777777777777777777777777777777777777777777777777
.
.
.
111111111111111111111111111111111111111111111111111111111111111111111111111111


- Pick this up as a brush and clear the current screen.  (the background
should be black)

- Move the handle of the brush to the top left (the * above).

- Position the brush just off the bottom of the screen and stamp it down.

- In the animation move requester, move the brush just off the top of the
screen (the exact # of pixels will be height of screen + height of brush
+ any slop) over full length of the animation.

- When you run the animation, you should see a smoothly looping line.

- Save these frames from the save frame requester (NOT ANIM).  If you
have 30 frames, put 30 in the number of frames box.  DPaint saves the
frames like this:  Name###, so to make these frames Imagine readly, put
the name pic.0 in the name field.  Dpaint will add three digit numbers on
to that, pic.0001, pic.0002, etc.

- OPTIONAL  In ADPro, crop out all but 1 pixel vertically of each frame.
You only need a brush one pixel wide, but Dpaint won't save this way.
(this is why you shouldn't use hi-res, because all that bandwidth will be
wasted anyway).

- In Imagine, created a tube with only a few circle sections and on
verticle section (unless you want to deform it).

- Scale it so it's long and skinny.

- Make it bright and phong shaded

- Map the dpaint frames onto the tube as a filter/transparency map.
(Pick Inverse video so the white in the dpaint frames is the 'show' and
the black is the transparent)

- Make the color in the attributes white, or whatever color you want the
stars to be.

- Drop a few of these around your scene, pointing from the distance and
nearby the camera.

Play with the length of the anim, the size of the gradient, width of the
tube, etc. to adjust the effect.

If you want to reposition them, there's only one position, not a
beginning and an ending, and the tube itself will show you where the star
is going to whiz and how big it will be when it gets there.

It's worked very well for me.

good luck

Light  refracts at surface transitions only.  You would have to create a

Since there is no other way to determine your actual experience using either
3DS or Imagine, I must say that the general tone of your message reeks of a
total lack of information about either program.

Imagine/PC 2.0 worked fine for me, as does v3.0. I don't miss Essence, Pixel
or Vertex. The v3.0 textures have provided me with a lot of new options. As
have some of the new tools.

3DS is more mature program than Imagine, with great renderings, booleans
work better than Imagine, excellent support, and plenty of 3rd party
developers producing new IPAS products. The manuals and tutorials are
thorough, the program is incredibly stable, and yes the price is out of the
reach of most hobbyists. Tough. 3DS and Imagine do have similar function,
each takes a different route to the same end, however I actually prefer my
3DS output for everything except certain raytrace effects that Imagine can
do, if I have the time to kill waiting.

have you tried the thicken command in vertex? it may give the illusion of

If you turn up the refraction value, you should be able to get the effect
you want.  None of the objects are truly 'solid'.

I found out why. In scanline the light goes through objects (which probably is
why there doesn't exist any shadows), but in trace mode, the light was trapped
inside the box. The fix is to use just an axis or make the box a fog object.

Hi, Guys!

If you don't mind MBI, the cube will appear solid by simply increasing
the index of refraction in the Attributes requester.  Glass is around 1.5,
and diamonds are around 2.5.  See what you think!

I'm not sure what you meant by a "drill effect," though.

  As I recall reading somewhere, there is a simple way to make a virtual

  I have a friend who recently (poor fellow) hand-positioned hundreds of
  such stars.  The effect was adequate, but a little regular.  I suppose
  the next step to the 'stars-replicated-along-a-sphere-as-path' would be
  to introduce some irregularity to their relative positions.
    Like someone said recently, though: Sky's the limit, so take full

ya I saw it in the prefs and think maybe it not -7 but -1 across all of
them, if you go and click in the black box it will reset it to 000000, if
you move all the sliders up one its 101010, but at defualt it is 010101,
which I believe maybe -1? heck I really am only geussing and have no
idea, but it can't hert to try.

Subject: Where did veneer and twinkle textures come from?

From: JOHN ROWE <[e-mail]>

Hi all!

I just checked out the great sample 3.0 texture pics in Im3tex.

Thanks to Steve and Ed for making this available.

One question though: I noticed a couple of textures in there whose names do not

appear in the texture.txt file accompanying my Imagine 3.0 nor in its texture
directory.

For example Veneer and Twinkle, although there were others as well.

Where did you get these additional textures?  Or am I missing something here???

Thanks in advance.

Best Regards from Down Under, John

I believe it will, but you may need to join the two objects as one. I
have done crystal balls this way and they look like crystal balls not
vacuum glass balls as you put it. heheh The only way to find out is try
it. If it looks good then thats all that should matter.

Ya this is how Wavefront does it, and probably LightWave too, so you
maybe right. I am not sure if Imagine will actually do it or not, but
have gotten shperes and cubes to look like they were working correctly
with single objects and boolean objects that were joined together.

        Sorry but there isnt a bug fixed version of Imagine2PC (except
buying new  3.0 release): the  only known bug fixed is the  conversion

#include   ---- Signing Your Animations (Chap11)---------------------

    If you want to put your name on your projects, here's a quick and
easy way to do it.  This technique will not work effectively if you
alter your camera's focal length during the animation (read: Changed
your camera's size bar).  It allows you to put things like "+1992
Carmen Rizzolo" in the lower-right hand corner of your animations.
But if you put my name in your animations, I get royalties! :)  The
following steps will be the last thing you do in your animation.
Just before you do your final rendering; do as follows.

    Boot up DPaint.  Make your screen resolution Hi-Res, 2 Colours.
Make your background colour (Colour 0) anything but black.  Make your
foreground colour (Colour 1) Black or a shade of grey.  The ligher
the grey, the more transparent your text will be.  Type out what you
wish and grab it as a brush.  As you grab your text with the box,
give about 3-8 pixels space away from the edges of the text on all
sides. Don't come in too close because it might get chopped off when
Imagine performs it's 'auto image-mapping' feature.  Save your brush.
Kill Dpaint.

    Boot up Imagine.  Enter the detail editor.  Add a PRIMATIVE;
PLANE. 1x1 section is all you'll need.  Scale your plane so that it's
closely the shape of your brush.  You might need to come back here
and fix the size after a few test renderings if the perspective is
thrown off by your plane being too wide or something.  But don't
worry about that too much right now.  Enter the plane's attributes.
Make the COLOUR whatever you want the colour to be when rendered.
Make the REFLECTIVITY 0,0,0 unless you feel artsy.  Give the FILTER
guns all the way up.  SHININESS and everything else, 0.  Make the
object a BRIGHT object by clickin on the BRIGHT button.  Now Click on
the BRUSH 1 button and load up your IFF bush. Make it a FILTER MAP
and tell it to USE GENLOCK.  This mean that Imagine will disreguard
the background colour of your IFF brush.  Hit OK and back out of your
attributes requestor.  Here comes the tricky part.

    Add an axis.  In the TOP VIEW, move your axis below, and to the
left of your PLANE object.. By the way, Your plane object should look
like a straight line from the TOP VIEW.  Your axis' Y axis should be
pointing north if you haven't changed it (Still, TOP VIEW).  Click on
the Axis, and then SHIFT-CLICK on the PLANE.  Now select GROUP.
Click on your axis again and enter ATTRIBUTES, and give your group a
name if you wish. Exit Attributes and SAVE your GROUP.

    Enter the ACTION EDITOR.  Go to the bottom of the pile, and
select the ADD BUTTON to enter the ADD mode.  Double-click on the
POSITION BAR of the bottom-most entry; which is was blank.  After
you've double- clicked on the POSITION BAR, frame 1 of the blank
slot, load up your Signature object.  Click on RENAME, then click on
your new object. If your Signature object it named SIG, call it
AA.SIG.  Now select SORT in the pulldowns.  Your signature object
should be up at the top of the list now, just below GLOBALS.. This
make it easy to do the next step.     Go through your script and make
the POSITION and ALIGNMENT BARS mimic the POSITION and ALIGNMENT BARS
of your CAMERA.  Now your Signature object will follow the camera,
and appear to not be part of your animation, but a superimposed
graphic.  Save and enter your STAGE EDITOR.     In the STAGE EDITOR,
Pick the Signature object.  Since it's in the same place as the
CAMERA, you might need to use FIND BY REQUESTOR to access it.  Once
it's blue (or purple), SCALE it down, down, down. Make it very tiny
so that it's very close to the CAMERA, and nothing will come between
your signature object and the CAMERA.  You might need to now SAVE,
and go back to the DETAIL EDITOR to MOVE and SCALE the SIGNATURE's
PLANE object (NOT the whole GROUP! -just the PLANE child object!) so
that the size and position of the text is in the lower- right hand
corner of the screen, and nice'n small.  You might have to go back
and forth from the STAGE and DETAIL EDITORS to get it just right.
Remember, if you just pick the whole group and SCALE and MOVE, you
won't see any changes back in the STAGE EDITOR.  You must Select the
PLANE when you perform your chages.. Important point here. When
you've got everything just right, it's time to render.

    This series of steps is actually much less complicated than is
seems. Once you do it a few times it'll be like second nature.  And
it's much easier than editing each and every rendered image; putting
your name in.  Of course, it's also cheaper then using a Choma or
Luminance Key system to super-impose text onto video.  Have fun!!

Same as above: rendering (3DS) is equivalent to scanline mode in Imagine.
You are right, 3DS havent many bugs.

Oh yeah, I forgot a step.  The star pic has to be really big.  In Distant
Suns, set the pointer tool to 'centering' (as opposed to 'info' or 'name'
or whatever).  This recenters the picture wherever you click.  Find the
portion of the sky you want to start with.  Save that as iff.1.  Click on
the center of the right edge of the screen (DS will recenter).  Click on
the right edge again.  You should now have the next 'sector'.  Save that
as iff.2.  Click on the bottom center twice.  Save as iff.4.  Click on the
left edge twice, save as iff.3.

Composite these quadrants together using ADPro.

I used 4 sections in this example to make it simpler, I think when I did
this for real, I used 9 sections.

This does require that you have enough memory, but if you render the pic
to 4 colors in ADPro, it should be reasonable (certainly don't use
24-bit).  The advantage is that you get a very realistic looking sky,
with real world star information.

I'll upload a star pic when I get a chance.  I've moved my modem to
another computer, (an old Mac w/o superdrive) so I can't do it till I
move it back to the Amiga (which is rendering).  Give me a couple weeks,
unless someone needs it right now.

(I've never uploaded to Aminet before, how do you do it?)

Hey Mike,

    And I wonder if that's why the stars work so much better in

DistantSuns.

Subject: Re: Solid and Drills.
Date: Wed, 15 Jun 1994 08:19:25 -0400
From: [e-mail] (Jude Anthony - DMC)

My understanding of solidness in polygon programs:

With a normal, solid object in the real world, light refracts thusly:

     -----
     |   |____    (Cheesy ASCII drawing)
     |  /|
 ____|/  |
     |   |
     -----

You can see how the light bends at the interface between the solid and the air
only.  In polygon based programs, a similar effect takes place.  When a light
ray reaches a polygon, it bends depending on the index of refraction of that
polygon.  So, a box constructed of polygons (like above) would bend light
exactly the same way as a solid box.  This makes it look solid.

To create the cube-with-sphere-vacuum effect you originally asked about, you
would need to create a cube, put a sphere inside it, _join the objects_, and
give the resultant object a refractive index, like of crystal or glass.  Since
the light bends only at the polygons -- just like light through solids --
you'll get the illusion of a solid cube with a spherical space in the middle.

Incidentally, this is the same sort of thing you have to do with bottles.  If
you make a bottle shape, it will appear to be entirely solid.  Therefore you
would need to make a bottle shape with a bottle-shaped hole in it, using the
same techniques described above.  (In any case, that's what I had to do with
my ship-in-a-bottle render.)

Although I'm not certain about this, grouping the objects might do the same
job.  That way, if you needed to move the bubble around, you could create a
second group to morph to.  (Just a weird thought that came up.)

Hope this helps!

Essentially, you create the outer AND inner shells of the object.  For
instance, a cube shell would look like:

      ________

Well, you get the idea.  I had a better discussion in the "Solids and Cutting"

Hi everyone!

I know I sent this request before, and I would like to express my
gratitude to everyone that replied. I have another request:

Is there any _Public_Domain_ program that converts DXFs or 3DS files
into Amiga Imagine V2 format. Being a student at college, funds are
hard to come by. I was fortunate enough to get Imagine V2 from Amiga
Format coverdisk, so those who have already sent me information about
Interchange (and the others ones that slip my mind that moment),
please understand why I send this request.

I have access to the following Software: (PC) AutoCAD, 3D Studio (Not sure
what versions though), (AMIGA) Imagine V2, and thats about it.

Thanks
Tele.

P.S. Also for those who seem to be getting a bit wrapped up the
cuurent flame over 3DS vs Imagine, don't mail-bomb me for this, but
please would you remember that some of us have enough problems
handling all the IML mail already, and our Sysops are getting a bit
stroppy over our bulging accounts! Thanks for understanding.

Well, Imagine is a surface modeler(is that the right term) as opposed to a
solid modeler.  This means that only the surfaces of object effect the rays
of light.  So if you have a sphere with glass attributes, Imagine will
make it appear solid(full of glass).  (Why would it do this if it is a surface
modeler?  Tell us uncle Tom.)  This is because Imagine didn't bother to look
inside of the object to see what it is made of, and just assumed that it
was made completely of glass.

To make a hollow glass sphere in a solid modelers, you would just cut out the
center of a solid glass sphere.

In Imagine(heres where I start making this up, ie not sure if this will work),
you might want to try putting a sphere with complete transparency and default
index of refraction(air) inside a glass sphere.  But then you won't even
see it.  So maybe the transparency of the glass with the refractive index of
air.  Hmm, probably still won't model the real world correctly.  Its really
hard to do with Imagine and just spheres.

But...heres a way that I guarantee(money back) to work(maybe).  It requires that

your glass sphere has a small hole in it.  First, think about when you `spin'
a wine glass in the detail editor.  It looks better if you have an inside
of the glass.
ie your outline looks like this          not this
         \\                                 \
          |                                  |
          =                                  -
so you wind up with this                 not this
         \\//                                \  /
          ||                                  ||
          ==                                  --
and your wine glass is completely inclosed, has an inside surface and an
outside surface.

Do this with a sphere...

           % = axis of rotation

          _____  %
         / ____| %
        / /      %
        | |      %
        | |      %
        \ \______%
         \_______%
                 %
                 %
Now spin it.

There may be a better way.  Two spheres inside of each other may work(I haven't
tried it).  But I know the above will work.

Well, I'm done rambling.

Recipe for a hollow glass sphere is as follows:
    Create a primitive sphere. Copy, paste, and scale it down so that
    there is a little space between them. Give the larger sphere the
    attributes of glass, and make the smaller one transparent. Group, render
    and serve with drinks(Preferably tequila, but marguiritas will do.).

Voila! A hollow glass sphere.

See ya,

I know what you mean, since Imagine, in its current incarnation, doesn't
support the display database, but I can say that it promotes pretty well
using the Retina promotion utility.  I'm currently running Imagine at
1280x1024.  Everything appears to work as before with the exception that
mouse tracking wraps at the right edge of a view when moving an object.

For example, when I grab an object in the top view and drag it toward
the right, it (and the cursor) pop to the left side of the view.  I can
release the object, grab the object at a point farther to the left and
continue to push it right off the view.  This anomaly doesn't show up
when a view occupies the whole screen.  I can work around it, but it
would be nice to have a modeling tool without the glitch.

Do other boards present the same problem with running at 1280x1024?
Will a new version of the Retina libraries help?  Experiences welcomed.

Subject: Essence and Imagine 3.0
Date:     Wed, 15 Jun 1994 17:51:00 -0400
From: [e-mail] (David Wyand)

Hi All!

I'm surprised that this hasn't been mentioned before.  Essence I and II
Vol. 3.0 doen't work with Imagine 3.0!  Now, before you all panic, I
have the solution.  Just use the new super Dave-o-Matic(TM), and
possiblly a wordprocessor that can load/save ASCII and has a
Find/Replace function :)

Here's the problem:  Take for example the bump texture from Essence I.
To get it to work with Imagine 3.0, you have to get the installer to
save the .ITX extension (just like for 2.9).  The bump texture is then
saved as:

bump.ITX
     ^^^(Remember this upper case ITX.  Its important later on :)

This is what Imagine 3.0 would seem to expect:

bump.itx

All of Imagine 3.0's textures have a lower case itx, and it doesn't seem
to like the upper case ITX (the textures don't show up in the load
texture requesture).  This is very un-Amiga of Imagine.  It should not
matter, but it does.

Here's the fix (you had to wait a long time for this, didn't you :)
Copy the Essence installer script and icon from disk one to RAM:.  Load
up you Wordprocessor (I use TransWrite) and open the Installer script.
Do a Find/Replace from ITX to itx (make sure that you have CASE
SENSITIVE turned on).  Then save the script (and make sure that you
don't save over the original icon).  Now, with disk one in the drive,
double click the NEW installer icon in RAM:.  Everything should work
fine, and all of the textures should be reinstalled with the lower case
itx.

The alternative to all this is to manually rename all 100 textures :)

Discliamer: I am not responsible for any damages that may occur by
taking any or all of my advice.  USE A BACKUP!  To make you feel better,
it works for me!

Maybe something like this belongs in the FAQ...

This is partially true in the sense that once you have arranged  the
background elements (excluding text) you must save the b/g which fixes
the elements (as with a painting package). The b/g can be saved as a 24bit
iff at this stage. The text can know be editted/created over the fixed b/g,
or more elements added such as boxes,other brushes etc.
As you say it would be ideal to edit the imported brushes at any stage ie
through layers.

The value can be changed in the input box say to 0,0,0 but when you leave
the input box the value is reverted to 0,0,6 ! This is very frustrating.
When genlocking through the opal without Montage all is fine. With Montage
through the opal there is a slight milkyness when genlocking.

Has anyone else had this problem ?

I presume the opal genlock colour is 0,0,0 I'll have a look when i get
home, but there is definately a difference between what opal normally uses
and what montage forces opal to use as colour 0.

Can anyone shed any light (preferably colour 0) ?

    This is an echo, of Mr. T's request.  I just locked onto an

there's no way to translate them to TDDD, but I'd love to render this

Light only bends where there is an interface.  I believe that the object
you want to make is a glass box that has a big air bubble (the sphere)
inside of it.  If this is so, a box with a sphere in it would work
correctly.  Set the index of refraction to that of glass.

   |Light Beam

         |
         |
         | Light Beam

In the above, we have the box and sphere.  The lights comes in from the
back (it doesn't matter which directio), refracts at the air/glass
interface, and travels in the box.  Then refracts at the glass/air
interface of the box/sphere.  Then again at the air/glass, and finally
at the glass/air at the front of the box.  It does not matter that this
is not "a true solid" as refraction only happen at the interface.  Hope
all this helps!

From: Michael Halleen <[e-mail]>

I put together a star pic as described in my star backdrop posts.
It's 1920x1200x2bits, and is about 17K in size, much smaller than I
thought it would be.  It took about 12Meg to create (I could have done it
in less if I coverted all the sectors to 2 bit images first and composed
on a gray backdrop rather than a color one).

I apologize to the guy from Germany who's been asking for this.  I haven't
been saving your messages, so I don't have your Email address.  Hopefully
this will get to you in time.

The star info is not scientifically accurate, the click-center technique
is not perfect.  But you can find the constellation Orion in the center
bottom of the pic.

Good luck!

From: Kelly Petlig <[e-mail]>

Well, it was mentioned that Essence doesn't work with Imagine 3.0 ... it
should be rephrased to Essence v1.0 doesn't work with Imagine 3.0, as
v3.0 works just fine.  If you EVER plan on upgrading to Forge, you will
NEED Essence 3.0 (2.0 was skipped).  Essence 3.0 installs itself with
.itx extensions ... of course, this was covered in the newsletter by
Apex.  Also, I'll use this time to announce my review of Forge in Amiga
Report 2.19 (ar219.lha on aminet)

     The installer for the new version of Essence includes the ability to
change the extentions to something that works correctly. It's worth the
money (IMHO) to get the alpha-channel utility. It's a wonderful boon
although it often takes some thought to implement (Forge helps a lot).

    I have a Merlin graphics accelerator that lets me promote ANY program

promoting Imagine in any resolution from the range : 2048x2048 , 1600x1200 ,
1280x1024 , 1024x768 , 800x600 ..it doesn't have a hitch!! NO problem at all
Moving , Scaling , Bending , Scretching  and ALL the other functions that
IMAGINE provide are running in EXELENT speed without ANY problem at all . Like
running it in amiga resolution WITH ONE DIFFERENCE!! Higher resolution modeling!

i
    In fact , IMAGINE has a problem !! Just try to promote Imagine and go
to Action, Project ,Preferences editor! Bliahh!!!!. NO using of the extra
space . No centered screen!!! Sure it is a program that it wasn't ment to use
higher graphics card!! * BUT WHY?? * WHY other editors works and they don't??
WHY Impulse doesn't follow the market needs ?? It is like C= when developed
the AGA chips the other clones had already forward to 24Bit cards!! GREAT lose
od interest!! (BTW Who is the new MAMA for the AMIGA?? ANY NEWS??)

                        Yours sincerely,

From: [e-mail]

Hi Mike,

There are a couple of ways to do this:
-  Lightwave will import 3ds, Save it as Lightwave, use Pixel3dPro
-  Use InterChange, it might have a 3ds converter ??
-  Use T3DDD lib, it might also have a 3ds converter.

The first suggestion I know it will work but the others I'm not sure. Can't
you use a pc program to convert 3ds to DXF ??

BTW how to get and where are those objects

Greetings Joop :-)

Interchange 3.0 should be able to handle this(as John Foust on here will
probably add),It does convert 3DS files...BTW,how large is this Aztec
City model,filesize-wise?

Subject: Amiga "Melt" executable and Farewell
Date: Thu, 16 Jun 94 05:01:03 GMT
From: "Glenn M. Lewis - ICD ~" <[e-mail]>

Hi, All!

    I promised to many people on this list that I would create an
Amiga executable for my "melt" program that appeared in the July '94
issue of Dr. Dobbs Journal.

    It turns out to be so small that I decided to attach it to the
end of this message.  I hope this does not upset anybody, and if it
does, I apologize.

    Usage is: "melt 10 normal.iob norm" for example, to create 10
extra melted frames of "normal.obj", using the file root "norm",
thereby creating "norm000.iob", "norm001.iob", etc.  I highly
recommend that you run this program from a RAM: disk so that your
drives don't get thrashed too much.  :-)  It is heavily I/O-oriented.
Also, I compiled it to work on the broadest range of Amigas, so it is not
a speed demon.  Be patient.

    I, too, was one of the original subscribers to the IML when
Steve Worley got it started many years ago.  This is, in fact, how we
met, and started tossing cool ideas back and forth for Essence and a
number of other projects.  Thanks, Steve, for starting the IML!

    But it is time for me to (temporarily) say "good-bye" as I am
under a great deal of pressure at my full-time job to crank out a lot
of [working] code in short order or I may not be able to take a trip
I've planned on for a long time.  Therefore, I must have no
distractions and am signing off of the IML for the first time.
Hopefully I will be back within a month or two.  Have fun, all, and
keep on rendering!

                        -- Glenn Lewis

OK, sorry to hear they did'nt solve your problem..I did a similar

three times and all landed on the ground fine..Hmmm? Are you sure the
distance to the ground matches the distance they are to fall. Doesn't seem

Travel Distance 450
Ground          -87.4961

your actual object would have to be at global Z 362.5039. Is this were
you have it? If not this maybe the problem..

Did you try 0 in the Min Angle from Z?

I know you said that scaling them made them disapear, and if thats good
enough for you then thats cool. But If you want them to stay on the ground
after they fall, then this will not do. Just trying to figure out why I
got it to work OK and these figures did'nt help you. Hmmm?

 The Installer asks if you want to have the proper extension required added

Ok, then why is it that apparently you cannot build a true magnifying glass

I have and use Essence 3.0.  Do you have a later version?  I know all
about the alpha-channel, and have used it a lot.  My point of the post
is that Essence _3.0_ produces texture files with .ITX (note, its in
capitals) and that Imagine 3.0 does not like this extension to be in
caps.  It must be lower case for Imagine 3.0 to recognize this.

Essence 1.0 DEFINATELY does not work with Imagine 3.0, but its WAS
Essence 3.0 that I was talking about, and is what I have.

Yes, Essence 3.0 does put the .ITX extension on the texture siles if you
want it to.  The problem, and the whole point of my post was that it
puts a capital .ITX and not a lower case .itx.  My copy of Imagin 3.0
does not accept a texture if it has an uppercase .ITX, only a lower case
one.  That's why I suggested using a wordprocessor to change the install
file.

Does your copy of Essence put .ITX or .itx, and if its the upper case,
does your Imagine 3.0 read it just fine?

  The Aztec city is not "incorrectly produced" and is not a loss.  Contrary
to John Foust and Scott Kervin, the .DXF converters in InterchangePlus and
Imagine 3.0, as well as Pixel3DPro, are far from being completely compatible
with AutoCAD .DXF output.  It is NOT because these objects are inferior
because they are on the 'net.  3D Studio reads all these objects just FINE!
 InterchangePlus and Imagine 3.0 will NOT!  If these guys ever get off their
arrogant high horses, they might find out for themselves.
  The Aztec city takes over 20 Megabytes of RAM to render in Imagine.  .DXF
usually does not have color or texture attributes and this is the case for
this group object.  It could probably be edited to be a really awesome
object but it will take a lot of work to apply all the brushmaps and
textures to get there.  The guy that made it deserves a lot of credit for
all the work he put into it.

I sliced the top off of sphere, gave it a non-zero refraction (I've
forgotten the actual number), cloned it, put them back to back,
put something behind the lens that I wished to enlarge, and pointed
the camera through the lens.  Voila.  Remember to use trace mode.

Hey guy,
    You CAN make a magnifying lens with Imagine.  I believe the
tutorial was in one of the early FAQ's.  It's all in the difference
between a sphere that's just a glass bubble, and a sphere that's solid
glass.  Index of refraction, if any of us passed our high school physics
class . . .

Gee, Ted, I'm sorry I'm so "arrogant" because I take the time to
explain my understanding of DXF to the readers of this mailing list.
Let's see, the list has lost Glenn Lewis and Mark Thompson in the
last few days, and even Impulse doesn't like to read this drivel on a
regular basis...

3D Studio is made by Autodesk, the people who foisted this DXF
"standard" on the world.  It's a poor standard because it is subject
to free and loose interpretation.  I can think of several ways to
represent something as elementary as a polygon: SOLIDs, TRACEs, LINEs
with thickness and elevation, closed POLYLINEs in the shape of the
outline of the polygon, 3DFACEs for triangles and quads, polyface
meshes with hidden internal edges, and I'm sure I'm forgetting a
method or two.

That's not getting into topics like the mapping between layers, line
types, pen numbers, blocks, inserted blocks, blocks within blocks,
text, etc. that are all subject to interpretation by any 3D developer
who decides to import or export DXF.

There's plenty of DXF files that will cause 3DS to woof, too.  What
do you expect a triangle-based program like 3DS or Imagine to do with
a lone polyline hanging in space?  At least InterChange handles those.
3DS in fact ships with two different DXF translators, one inside the
program, and one external, and they behave differently.  Yes, I do
expect that a $3,000 program from Autodesk will do what it claims to
do.

I've never said that InterChange's DXF translator was perfect.  I've
never said "it'll eat anything from the Internet and spit out a
ready-to-wear Imagine object" either.  In fact, I go to great lengths
to explain *exactly* what it handles and when.

And don't flame Kervin because he's had no troubles with the
converter, either.  It's perfectly possible for two people to have
completely different experiences with the translator.  On the other
hand, if you're really working with AutoCAD and RTFM, our translator
will do what we say it will do.

Please, compare the translation and the manual and the tech support
and the price of InterChange to any other 3D translator.

What really irks me is the fact that Pixel gets mentioned when DXF
comes up.  Please, go ahead and quote the entire two or three
sentences from their manual that explain how they handle DXF.

Is that the kind of support you like?  I'm not even sure if the phone
will be answered if you call Axiom for tech support on Pixel Pro.
And they've even referred *their* customers to *us* because they know
their DXF support really bites.

Meanwhile, 3D magazines ask to reprint the explanation of DXF from
InterChange's manual, and it's in the Toaster manual, and even one of
our other competitors *plagiarized* vast sections of our manual until
we caught them.

Oh, and I'm sorry that I haven't examined, converted and reviewed
every object on Avalon for your personal pleasure.

I'm going to give you a free clue:  Smart, nice, intelligent people
drop out of this mailing list because of all the whiners who know the
price of everything, and the value of nothing.

Thanks, Stethem, for your post.  And I was hoping it was something on my

also held onto the object file, in hopes I'll be able to get it to load.

    Someone else suggested I try the -a option when I unzip the file,
since Imagine claims it can't find the ENTITIES file when I try to unload
the version I unzipped with just the straight unzip command.

     Essence 3.0, Imagine 3.0 and Forge all work correctly with proper
installation (for me). Perhaps try installing it again.

Hi everyone,

    Well i still haven't found a button to activate this but i'm not
100% sure that it's need anymore.

    I tried a few quick tests by setting making sure the 2 entries in
the prefs were both on 000 (default i think).  Rendered a picture with a
ground and a couple of objects with the 'sky' parameters in globals all
set to 000.  I then rendered another picture with no ground and the same
settings and was able to composite the 2 in adpro and dpaint as well.

   I don't reallt know if this was possible on 2.0/9 as I have always
automatically set the Genlock flag.

Anyway thayt's just what i tried. Let me know if anyone finds out
anything else ...

Hi there. My understanding of the upgrade for Essence is as follows:

If you own Essence I, you would have to pay for the I & II 3.0 upgrades
(since you don't own II, how could you upgrade it?)

If you own Essence II, you get the II upgrade free. You'd have to pay for
the I 3.0 upgrade (since you don't own I, how could you upgrade it?)

If you own Essence I & II, you get II 3.0 for free, but have to pay for
the I 3.0 upgrade...

Hope that helps...

Hiya. Alpha channels are a special way of handling textures. For example,
by using alpha channels, you could have a chessboard where the black
squares are, say, veinedmarble, and the white squares are wood or
something. Alpha channels is the tool that allows you to do this sort of
thing.

Hope this helps!

I downloaded aztec city and when decompressed it has the dxf extension. I

some of my tricks are thus....
I don't just convert directly to imagine. convert to another format then Pov, LW

Vetex imports very well and has some very nice clean up features, the face
counts etc. give you a lot of detail on how close you are to a clean

at first would not convert to imagine. One last thing there are very few
objects I have not been able to convert directly from within
interchangeplus. I usually just double click on the converter and size
things up a bit then convert, this gives a bit more accuracy and detail.

   Allright, here is the status on the "magnifying glass" issue up to now as
far as I understand it.  Thanks to everyone who replied on this.  It does
seem, however, that most people are convinced that you can actually build a
fully functional magnifying glass in Imagine.

   My verdict: There is definitely a difference between the way Imagine and
Real 3D handle a magnifying glass.  Real 3D does appears to render a more
real (pun) magnifying glass than imagine IMO.  I have done some tests with
Imagine and PovRay with similar "lenses" and scenes (and so has Andy Jones
with Imagine and Real 3D, thanks for the great example Andy!).  I don't have
Real 3D, but PovRay is similar in the sense that it has CSG objects.  The
CSG lenses seems to actually correctly concentrate the light (it doesn't
burn the object behind it however ;-) whereas the Imagine lens will cause a
bright "shadow" with a dark border.  As well, even though the Imagine lens
will magnify the "image" behind it, it doesn't seem to be able to correctly
"reverse" the image as the Real (double-meaning) lens.  Andy has a simple
little example image (10K) which shows some differences, however subtle (but
effective) due to the closeness of the lens to the object being magnified.

   These differences do seem to be linked to the fact that the Imagine lens
is a glass shell whereas the CSG lens is a glass volume.  I'll let the
physics experts explain the details however.

   Please don't get upset and flame me if you don't agree, present your
arguments,  I'm opened minded.  I did see a difference however!

regards,
Alain.

What does 'CSG' stand for?  Are the Real 3D lenses parabolic or spherical?  I
read one post which described how to make a lens in Imagine using a slice from
a sphere.  If we are comparing this spherical lens with a parabolic lens it
could explain the differences.  Has anyone tried to make a parabolic lens with
Imagine?  Shouldn't be too tough:

    -Use a plane to slice a cone - the intersection should be a parabala
        -Spin the parabala to get a parabolic dish
    -Copy, rotate 180 deg., join and Voila (BTW, how do you spell 'voila')

        Cryptic to say the least! At the risk of sounding thick could some
more explaination to the "route" be forthcoming. I have run across many DXF
files that I have wanted to give or take from other imaging software. I
don't have a copy of Vertex, I use Freeform3D for any outside object
support for Imagine. Incidently, Freeform3D is quite impressive, what with
it's rail morphing functions and its "bones", now in both the horizontal
and vertical axes. The authors support is both timely and he is highly
receptive to enhancement suggestions. But, I digress, has anyone been able
to get DXF to and from Wavefront?

Subject: Animated brush map problems
Date: Fri, 17 Jun 1994 12:57:41 -0500 (CDT)
From: Michael Halleen <[e-mail]>

Hello,

I remember hearing someone asking about this on this list a while back,
but I don't remember hearing the answer.

With the 'transistion frames' removed from the action editor, I've been
having trouble using animated brushmaps in Im30Amiga.

Here's what I'm doing.  I've got a scene with a small video monitor in
a room.  I've got three different three second clips of digitzed video
that I want to appear in the monitor at different times, seperated by
intervals where the monitor is off.

The video clips are in the directory ac:s/v/ and called
video1.0001-.0090, video2.xxxx, and video3.xxxx.

First I tried creating three different states for the monitor object
STATE:1 used video1, etc.  The screen portion of the monitor is a
seperate object that is a child in a group.  I tried both updating the
object and the group, choosing the 'properties' button both when creating
and updating, but when I changed groups using 'set to', it didn't change the
map.

So then I created three seperate objects, screen.1, .2, & .3, each with a
different map.  In the action editor, I put .1 in place, but because of
the 'no transition frames', I had to enter two actor bars for the second
and third screens.  IOW, one actor bar lasting one frame, another lasting
89, otherwise I would get a morph.

Screen .1 worked fine, but when it got to .2, it gave me 'error opening
ac:s/v/video2'.  It was looking for the filename with no number
extension on it, and yes I *did* set the max sequence number in all the
objects.

What I had to do was render the first sequence, then delete the .1 actor
bar altogether, then make one single actor bar for .2 and render that
sequence.  Ditto for .3.  I suppose I could also have created two cloned
objects, one for each .x.

Is this the way it's supposed to work?

   Hi All.

   Do Imagine 3.0 know that colored light bend differntely then
   non colored light.(Well non colored light is colored to, i know)
   Well the color red have another wave lenght the green.

   The magnify glass made me think, if we can make a magnify glass,
   can we make a prism??

This question was discussed to great length about a year ago, and I believe
the answer was no.  Imagine does not take into account the fact that light
is made up of different wavelengths, and that those different wavelengths
bend at diffferent angles when passing through objects.  Of course this
was when 2.0 was out, maybe it has changed, but I seriously doubt it, this
would probably make rendering times increase exponentially.

From: [e-mail] (Lesk)

I just read my message to the IML and I was not very clear about a couple
of things(School is out and so is my bRaIn.....). To those who pay a fee
for mail I apologize for having to make this correction.

1. Interchange plus has worked on hundreds of DXF's, aztec is the first I
have not been able to convert.
2. Since DXF is at best flaky, converting frequently leaves extra faces
points etc. that need to be cleaned up. That is where vertex comes in
handy.
3. Converting a dxf to say Lightwave then pov then wavefront then Imagine,
really allows interchangeplus to do some cleaning of its own.

I wanted to make sure it was clear about interchangeplus. I have found it
to be very usefull, and in my original post it sounded as though I was
saying the oppisite.

Sorry for the confusion.

Subject: ToolManager Buttons (BINARY)
Date: Fri, 17 Jun 94 13:51:08 -0600
From:  (Matthew J. Feifarek)[e-mail]

Here are some ToolManager DOCK icons that I've been using.  It occurred to me
that some of you might like them.  I don't have AGA, so I'm running an 8 color
WB, so they're limited in that respect.  I hope you like the palette... or that
you can easily switch to one you do.  Basically it's similar to the 4 standard
colors plus a monochrome ramp of 4.

They are in Dpaint's animbrush format, which ToolManager handles in a very cool
way.  I have more I've made, but they're not Imagine related :)

Have fun.

PS. I _USED_ imagine in their creation even, so they're totally legit. ;o)

From: Andy Jones <[e-mail]>

Hi Gary,

> What does 'CSG' stand for?  Are the Real 3D lenses parabolic or spherical?  I

Constructive Solid Geometry. These are primative objects such as a Sphere, Cube
etc which are described using a mathematical formula and are truely volumetric.
They can't be point edited like the polygonal surfaces found in Imagine, LW,
etc. You can stretch, size, shear, them etc and use BOOLEAN operations on them
to create more complex shapes. They render very quickly and no matter how close
you get to them you'll never see any facets, it's a bit like Postscript fonts
compared to bitmap. They suit some applications extremely well and suck for
others which is why Real also has phong shaded freeforms as well as cubic
b-splines.

In the lens example I created I used a spherical lens. The reason Real can make
a 'true' lens is because CSG objects are volumetric and the BOOLEAN operations
are considered when calculating the refraction through the volume. Unless you
really need to make an accurate lens I wouldn't worry about the differences,
refraction alone will give a good enough effect.

     The file on avalon.chinalake is in .DXF.  .DWG is AutoCAD Release 12
binary format.  AutoCAD will read these in, otherwise you are out of luck,
AFAIK.

     I agree, InterChangePlus is an excellent product.  However, the .DXF
importer is far from totally compatible with all .DXF, and if the .DXF
belches on Imagine V3.0, Pixel3DPro and Caligari, it will belch on
InterChangePlus.  Also, InterChangePlus has some kind of problem with its
.iob saver but the TurboSilver saver is just fine and loads into Imagine
smoothly.  The nice feature of Pixel3DPro's Imagine saver is that it would
save the object as a grouped object (nice for editing) which InterChangePlus
won't.  Too bad that the Pixel3DPro's Imagine saver also has a problem with
generating bad edges, duplicate points, etc.

>"Imagine's DXF import is broken."  Give me a break....no program handles

     Please, 3D Concepts is REALLY BAD!  It may have come from AutoDesk but
it must have been written by somebody that was completely disassociated with
AutoDesk.  The version for Windows is so slow as to be almost completely
unusable. And its .DXF importer is equally as bad.   Also, to add fuel to
the .DXF discussion, when .DXF was established as a graphics standard way
back when ( BTW, .DXF stands for Drawing eXchange Format), you could get
AutoCAD for $70US and it only supported 2D drawings.  So, the 2D format is
rock standard.  Every program I know of that uses .DXF importers will import
a 2D .DXF, no problem.  Now, AutoCAD is somewhere around $7000 but it has 3D
CAD capability.  3D CAD has been steadily evolving and so has the .DXF
standard.  It also depends on how the CAD 3D model was saved out.  Even
AutoCAD users have difficulties bringing .DXF back into AutoCAD without
knowing how they were saved.
   Also, regarding your last statement, "But no-one tries".  Can't disagree
with you more about this.  I have tried and tried and tried (but maybe I am
no-one?).  Have you heard of DXFer, ACAD, DXFto3DS, etc. etc.?  There are
lots of people trying everything to find a smooth way to convert .DXF to
Imagine.  I just don't think there is a really smooth method of doing this.

The problem has to do with line feed carraige return and those other unseen
characters. The pc handles text differently as well as many of the servers
that transfer your mail. I beleive there is a text converter out on the net
that takes care of this conversion PC, Mac etc.to amiga but I don't

"Some kind of problem"?  Would you care to describe this problem in
more detail?

Huh?  You've got that backwards: InterChange translates sub-objects,
while Pixel doesn't.  And InterChange also creates Imagine "groups"
(a very different Imagine concept than sub-objects) from collections
of faces with the same material attributes.

No, even 2D DXF isn't standard, and plenty of CAD companies have
trouble with it.  DXF is a poor standard for 2D and 3D, for the same
reasons.  I have never heard that AutoCAD once cost $70 and today
AutoCAD sells for about $2800.  You tempt me.  You make me want to
stand up and scream "You have no idea what you're talking about."

Lesk just confirmed that he has had the same problem.  It would seem
that early copies of Essence had capital .ITX until Imagine 3.0 was

From: "Steve J. Lombardi" <[e-mail]>

Does anyone know if the Imagine staging language will work with 3.0?
I never used it with 2.0, but would like to try it out now. It seems
that since the staging file has changed in 3.0 that the staging language
would have to be upgraded. If there is a 3.0 compat version out there-
what is the name on aminet?

Well, it would seem that you're right.  The first disks that went out

Subject: DXF files
Date: Sat, 18 Jun 94 18:25:04 EDT
From: [e-mail]

  Everyone has to keep in mind the DXF files are only as standard as anything
else in the computer industry.  Hundreds of different programs use DXF for
thousands of different things.  Some use polygon, some, solid, some don't use
faces, some don't even use 3D space to represent 3D objects, and I haven't
even touched on the 2D aspect of DXF that many programs use.  To expect any
one company to handle all of the possible formats of DXF is silly.

  But enough DXF flames.

  Here is a possible solution for you PC users.  There is a program for
Windows called 3D Design Plus, made by CompuEasy. (I think)  It is basically
a 3D CAD program, but I have found that if I import a DXF, that gives Imagine
trouble, into the program and then export it out as a DXF, it does not give
Imagine problems anymore.
  This is a good 3D CAD program for around $75, that has some good DXF
translation built in.  It will also import 2D DXFs, for extrusion into the 3D
world.

Why not try it?

Here's what I think: it won't be possible.  While Imagine can model a
magnifying glass, and other lenses to distort an imagine, it cannot bend
a light source.  You cannot build a lens to concentrate a light to a
point (such as to burn 3D ants :)  This also means that it doesn't work
the other way.  You can't focus a light, or, as far as I know, reflect a
light (ie: you can't have a light point in one direction and reflect it
in another to light up an object.  I think that would take something
like radiosity).

Hi Lesk!

I don't believe that FORGE was really written to open Imagine textures.
At least, that's my understanding.  Essence textures contain an extra
IFF chunk that helps FORGE along.  Also, there's the datatbase of
texture info that FORGE comes with.

I just tried the included BATHTILE texture from Imagine 3.0.  The two
usual requesters came up (the one about the texture missing the IFF
chunk and the missing database).  If you wanted to not have the second
requester pop up, you could always edit the FORGE database to include
the Imagine textures.  As for the first requester, the only for that to
go away would be to patch the Imagine textures.

I wonder what that RNGS chunk does anyway?

This however, will not work well if you have reflective objects that you
want to render, especially if you want them to reflect the background,
and yet render on a black screen. This is where the genlock option was so
useful!

Why not use Global or Localized reflection maps if you want background
reflection?  These don't show up as part of the background but will give
reflections.

Hi PC fellows,
        this is just an extract from an italian computer magazine,
Commodore Gazette, about doing lens with Imagine:

-enter the detail editor
-add primitive sphere (not add sphere, add primitives and then sphere):
 circle=48, vertical sections=24
-pick sphere, pick points, drag box pick method
-multiple select all points except for the first (top) 5 lines (sections)
-delete selected points (functions menu)
-pick object (pick method menu)
-move ONLY the axis (shift-m) to the bottom line of points/section
 (looked from front view): do this step more accurate, use zoom in
-copy selected obj and paste it
-invoke transformation req, scale it -1 to z axis
-select the two objs and merge them
-invoke atts req:
 color and filer=255,255,255    harness=100 to 130   index=1.2 to 2.0

        This method is much  realistic  one,  positioning  lense  above a
plane (e.g a brush mapped one) and  moving lense far from it, Ya get also
the tipically effect of getting an upset image.

PLEASE NOTE: do not use spin or sweep function  (drawing  profile) coz so
             Ya cannot manually draw a perfect shape (as sphere primit.)&
             Ya get an increment of rendering time.

Hi!

>Can you explain alpha channels please.

Do you mean alpha channels in general, or Essence alpha channels?

Generally, an alpha channel is used when you wish to merge two or more
pictures together.  Let's say you want to put an airplane from one
picture on the sky of another.  An alpha channel is a grey-only picture
that tells the software what part of the airplane picture you want to
paste onto the sky.  What you would do is make a white picture of the
plane on a black background (some programs use the reverse: black on
white).  Then, when you merge the picture of the plane on top of the
sky, the software uses the alpha channel of the plane to paste ONLY the
plane, and not the other crud in the plane picture.

You don't have to just use black and white in an alpha channel.  Using
greys tells the software to only partially (transparently) paste parts
of one image on top of another.  In the above example, if you used a mid
level grey, instead of white, the plane would be partially transparent,
showing some of the sky through it (almost ghost like.  A ghost plane!).

Essence alpha channels work the same way, but use the reflection of
Imagine objects to tell an Essence texture where to apply itself.  Sort
of like restricting a texture to a subgroup of faces, but you are able
to fade the texture out (remember those greys?).  I don't think I can
explain how to go about this any better than the Essence 3.0 manuals.

Hi Mike,

    When you asked me about the length of time it was taking you to

anything for a long time.  Well I have a couple of things you might like
to try to speed your trace times up..here goes :)

Preferences Editor....

        EDLE 50 (Depends which one your using)
        AARC 50 (  "        "   "   "    " and how many jaggies)
        RSDP 1  (pretty good speed improvement)

  Of course this all depends on whether you need reflections or not too.
I had a 320x256 image that scanlined in 11.4 and traced in 15.5.

  Something to note though, with the above things changed in the Prefs
editor, scanline will only produce a black image.  I had to reload my
normal prefs.  Could you rety this out on your machine and let me know
whether it does the same?

See ya

Subject: Rectangular, Parallel Lights--BUG!
Date: Sun, 19 Jun 1994 16:05:00 -0400
From: [e-mail] (David Wyand)

Hi All!

Could someone please confirm this:

In Imagine 3.0, you can have parallel rectangular light sources (yay!).
I think that I have found a bug with them.  In the detail editor, make a
plain axis.  Edit its attributes and click on light.  Make the light
parallel and rectangular.  Also click on NO Lens Flare (we don't want
this light to flare for this example).  Rotate the axis so it points
down and raise it in the world Z-axis to some height.  Adjust its size
so that it reaches the ground (zero Z) and has some width and height.
Save it.  Make a ground (dark colour) and save that too.

Oh ya, the reason for making the light in detail is so that a texture
can be added to it.  Add the default French Windows, if you'd like (it
doesn't matter, the bug works with or without it).

Go into Stage, and load in the light-axis and ground.  Be sure that the
light is pointing at the ground and that the camera is pointing at the
place where the light will be shown.  Make this lighted are take up
about 1/3 of the rendered screen.  Now quickrender.

Here's the bug: the rectangular light source goes off into infinity in
one direction, and is limited (as it should be) in the other.

Go back into detail (save the stage!) and turn off the 'No Lens Flare'
button (ie: allow the light to flare if we used the global texture, but
don't use it for this).  Save the axis.

Go back into Stage and quickrender.  The rectangular light source is
limited on both axes!

The bug: The parallel, rectangular light source is limited by its axes,
as it should be, when you do not choose the 'no lens flar' button in the
light requester.  If you do choose this, the light goes on for infinity.

Thanx for checking this out...

                                        -Dave

   Agreed.  Imagine's refraction is accurate and therefore realistic.  I did

good, it just gives a slightly different result from a CGS lens because it

Hmm, kinda what I guessed.  This really has little to do with whether an
object is solid or just a surface.  As you can see by the magnifying effect,
Imagine does calculate the lens correctly even though it is only calculating
at the surface.  That is because that is how it works in the real world.
Light only refracts at the border of two mediums, and the middle of the glass
has little effect on the light(OK, so speed and color and other things may
be effected, but let's not be anal.  I'm not a physicist, after all.)

The reason you can't burn ants in Imagine (this is a guess), has to do with
the way Imagine "casts rays".  When projecting the ray from the object
to the lightsource, it seems like something isn't being done "right"(not
that this is a bug, just the way they did it)  Perhaps Real cast their
rays from the lightsource(is this posible?).  Or perhaps when (in Real)
a ray encounters a transparent object with a different index of refraction,
multiple rays are cast from the hit point back to the transparent object
to determine if it is focusing light.  Hmm, interesting problem.  Anyone
know how this is handled?

In any case, it has little to do with the object being solid modeled or
surface modeled (I think:)

Maybe I'll post this to rec.comp.graphics.????  and see if someone knows.

VistaPro has the option of saving landscapes as a TurboSilver Object, which

Hey, Soren, you said on Jun 20 :

Because a reflection brushmap is just that.  It's a brushmap.  It doesn't know
anything obout the other objects, unless you say, render a picture of the object
s
and use that as your reflection map.  Reflection maps are most useful if you hav
e
chrome objects.  Just make a map with a black background, and a lot of squiggly
white lines and white puffy areas, with smooth gradation to the black.  Then app
ly
that to your chrome object.  If you want real-world reflections, I believe you
must use ray-tracing.  Scanline rendering will only let you reflect the ground a
nd
sky colors, I believe.

I decided with all the posts about the Aztec city DXF that I want
to have a look at it. I converted it with AccuTrans 3D directly
and without a problem got it to load into Imagine. It is pretty
impressive and the person who did all the work deserves a lot
of credit for an astounding piece of work. I used Gigamem to render
it but had a few problems. Can someone report the best setup for
Imagine & Gigamem. The only way I could get it to work was to
use only virtual memory. If I tried use normal memory first it
would tick off all the chip & fast and only a little of virtual
and eventually when it ran out of chip & fast would crash. I was
using 5MB buffer with 300k cache with a 40MB partition. In the
meantime I better search for my Gigamem manual because it might
help.

It appears the RNGS chunk sets the min/max limits to the textures, for
the sliders, that is.  I haven't experimented with it directly, but I
probably will for some bigger or smaller ranges that I want to experiment
with easier than typing it in.

    It's virtually impossinle to get an accurate, perfect
reflection like the kind you're looking for with most renderers. Read
the other posts about magnifying glasses/prisms/wavelengths. The
reflective nature of a compact disc relies on a sort of primastic
effect. Something that can't be done with a ray-tracer.
    You can simulate it fairly well by modelling a CD and giving
it highly reflective attributes (like chrome). The rainbow reflection
would come from the interaction between the object and a custom global
reflection map. If you create a global reflection map that looks like
a rainbow of colors you'll probably get good results with the CD
reflection thing.
    Hope it helps...

    Correct. Mainly, I believe, because you're not tracing a
photon from a light source to the camera. It goes the other way. A
"photon" or ray is emitted from the camera. What it hits determines
what you see.
    I'm not sure, but I think radiosity is just a more complex
simulation of "real world" conditions. Instead of tracing a ray to an
object and finally to a light a radiosity rendererer would trace a ray
to an object, determine what should happen at that point and then
shoot more rays out of the object itself. One ray could turn into
hundreds as soon as it hits another object. Of course, this is just
speculation...
    Even if you could manipulate light in a "real world" manner a
prism would still not be possible unless the nature of the
electromagnetic spectrum were taken into consideration with the
renderer.
    Light, as we all know, is made up of different wavelengths.
White light (255,255,255) in Imagine is not a combination of every
wavelength in the visible EM spectrum. It is 100 percent of red,
green, and blue. So, it's not "white" light in the real sense.
    To do a prism effect you have to tell the renderer that every
color is made up of different wavelengths of light, and that your
refractive materials are made up of physical substances capable of
manipulating the colors on the basis of their wavelengths. Etc, etc.,
etc...
    Needless to say, it would take a lot of calculation...

I've just joined this group and have little to no experience with rendering in
either Imagine or Real3D.  But I do know this much.....

As stated earlier, the light is only effected where an air/glass interface is
met.  In the case of the Real3D object which is modeled as a solid there are
two air/glass interfaces (one on each side of the lens), just as a REAL lens
would have.

But in the case of the Imagine lens which is modeled as a lens "shell", with
two thin glass shells stuck together, there are really FOUR air/glass
interfaces.  One one EACH side of EACH glass shell.  IMH(and unresearched)O,
this would signifigantly affect the way the rays would travel.

Yes and no. A 'magnification' in Imagine isn't optically correct whereas in
Real you can be because it considers the resultant volume of the object after
the boolean operation. As I said before, the results aren't very different. But
you can see one object magnifying correctly whilst the other distorts the image
and shows more of the background in the lens. Refraction alone also turns to
rotate the image at the edges - a chequered pattern being a good example, a
true lens won't take the background to the east of the lens and rotate it north
and south, it will just bend it a bit... This is hard to explain.. I'll try and
get an image on aminet in the next couple of days...

> The reason you can't burn ants in Imagine (this is a guess), has to do with

My guess is that Real considers refraction through the object when calculating
shadows. You can burn ants in Real...

I use it with "Virtual Memory First."  This is because Imagine makes lots
of relatively small allocations (I think I have things set to ... let's see
... start GigaMemPrefs ... Min.Size 512) to make sure that MOST allocations
go to virtual memory.  You could tweak that if you only want larger chunks
in VM but a Min.Size of 512 work pretty well for me and overall penalty
with speed is something I can live with.

Subject: Staging has bad IFF
Date: Tue, 21 Jun 1994 01:32:46 -0500 (CDT)
From: Michael Halleen <[e-mail]>

Hello,

Has anyone else had this problem:

I was preparing to render some test frames (400x250), before going to bed
(it was about 1am).  I rendered one, 'show'ed it, selected the rest, and
pressed generate (not Make) when Imagine (3.0/Amiga) tells me that the
staging file has a bad or malformed IFF structure, or something like that.

This is VERY bad, because I was supposed to meet with a client tomorrow
at 8:30 AM and show him that rendering.  Now I've got to reconstruct my
last week's work (from my last backup), and I'm not going to do it
tonight cause I have to work all day tomorrow and I need to sleep.

On a related front, I think, has anyone had a problem where if you render
a scene as an Moive, and don't delete files after using them, using the
default directories, Imagine tries to write both the pix and the anims to
the same location on the hard drive?  I can not, since 2.9, generate a
Movie on the same hard disk as the pix, it always generates errors that I
need QBTools to fix, and the fix is to delete some files.  I always
redirect the Movie to my syquest.

Is this a hard drive problem?  I have a Seagate 345 MG and an IVS
Trumpcard Pro SCSI controller.

The bad iff problem seemed to generate similar errors on the hard drive,
although as I mentioned, I was not doing a movie when this error
happened, it immediately followed a still render (one that worked
perfectly, btw).

Thanks for any help.

Nik, what if you used a Global Brush Map in the Global Requester? That

You need to make another object with some changes made to the texture and
then load it into the frame you want your texture to animate to. This
should give you a time line bar to the new object, which will be your
animation sequence for the texture. Theres more to this, but this should
give you a good start and work for a basic texture animation or morph on

Don't have the object, but the best I can think of is use a brushmap with
a CD patterns on it and apply it to a chrome disk, then make a disk and
extrude it to the thickness of the CD and give it a Glass attribute with
an Index of Refr of maybe 1.50 to 3.55. quite a margin but I'm not really
sure of this, You'lle need to experiment. Then fit the first disk inbetween
the glass one. Should be halfway desent.

I would think this would work, But maybe you should use Generate First
and then use the palette from that picture. Also you should try and find
a frame that has all the objects you are going to use in your
animation as the First one...Though I have heard from others that there is
still a problem with this keeping the palette locked throughout the animation.
But I have not experienced this problem yet as I haven't been able to render
as many anims as I would normally have by now.

The .fp version of Imagine is already 040 optimized, and I would suspect
it autodetects an '040 if you have the '040 libraries installed.  Of
course, at this point, that might be expecting too much from Impulse.  I
know when I got version 1.1 the speed increase was two fold over 1.0
because they optimized it for the '040 ... I don't know how much that
holds anymore, since they use PeeCees for development now.

Actually, the shell of an Imagine object is infinitesimally thin, so it bends
light only once at the shell... not twice.  This makes for an equivalent
number of refractions (2), so an Imagine lens is pretty close to a CSG lens.
I've got a nice version of one, and I think I've found the problem everybody
is experiencing.  Essentially, in order to get good refraction out of an
Imagine lens, you need to pump up the polygon count.  My low-count lens does
magnify, but it introduces anomalies, probably related to the low number of
polygons and the calculations necessary to do Phong shading on them.  My
high-count lens does a beautiful job of magnifying.

VistaPRO, etc...  I don't have a 24bit card (just DCTV) but it looks like
they busted 3.1 loose and I'm thinking about an upgrade.

Thanks.

Subject: EGS Animations and Magic Lantern
Date: Tue, 21 Jun 1994 12:23:49 -0500
From: [e-mail] (Cedric Georges Chang)

Previous posts have asked about animations on EGS cards.  I mentioned that
Magic Lantern can create anims (as well as sync sounds to them).  I went
ahead and did some tests with Magic Lantern so that people can have a better
idea of what it can do.


The Animation
-------------
The animation used in the testing is part of an old Imagine Project of mine.
It consists of a space station; the first 40 frames of the 120 frame anim
has the camera panning and moving towards the station, the last 80 frames
show the internals of the station in motion.  Overall the deltas (changes
between frames) aren't bad; the black background negates the the large deltas
usually associated with camera pans, and the station in action just consists
of a two plates crushing the external tank of the space shuttle into a thin
sheet of metal.
I hope to do this same type of test again but with an animation with more
complicated motions.  I'm sure a more complicated anim would give higher
file sizes and slower framerates.


The Results
-----------

   Resolution   Dithering   File Size            FrameRate
   ----------   ---------   ---------            ---------
   320x240x24       -         3.9 MB             28 frames/s
   640x480x24       -        14.2 MB             14 frames/s

   640x480x8      none        3.6 MB             28 frames/s
   640x480x8      random      3.9 MB             28 frames/s
   640x480x8      floyd       9.5 MB             27 frames/s

   640x400 DCTV     -         1.8 MB             30 frames/s

The 120 640x480x24 images used to make the anim are 36.7 MB.


The Testing
-----------
I chose the Spectrum output format, which also happens to work on my Piccolo
card.  For some reason double buffering doesn't work correctly with EGS cards,
so all of the anims except the DCTV one were played single buffered.  The anims
were set to play at a maximum of 30fps.  They were compiled in 'Super Charged'
mode, the equivalent of long word compression.  Anims play faster, but are
slightly larger than the byte or word compression options.

The 8bit conversion and dithering was done with Art Department Professional.
The 8bit anims used a fixed palette.  For dithering, floyd looks the best, but
isn't well suited for anims.  Random is meant specifically for animations.

I timed the anims by having them play five times in a row and dividing
600 frames by the time.  I rounded down the results.

The testing was done on an A3000 with a 28MHz 68040 and an EGS Piccolo.  All
of the anims were played from ram.


My Opinions
-----------
The 320x240x24 format seems the best use of Magic Lantern with EGS.  The file
size is reasonable and it has a high framerate.  Though the animation appears
small on the screen, it looks very good.  At 14.2 MB, the 640x480x24 is too
large to be practical.  It is also slow which tends to compound the problem
of single buffering; you really notice the screen redrawing.  Double
buffering should help in smoothing out the anim.
After looking at the 24bit anims, the 8bit stuff just doesn't cut it.  With
no dithering, you get the banding effect instead of smooth shades of color.
Random dithering looks okay, but the images are much grainier; they have that
dithered look to it.  Floyd works well in this case, but the file size balloons
upwards.  All of the 8bit anims played fine single buffered; the higher
framerate smoothes out the animation.  If you look for it, you can see parts
of the screen being redrawn, but it's no big deal.
DCTV comes out ahead with its highly compressed format and high framerate.
The negatives of DCTV are that certain items don't come out well, such as
sharp text, color gradients,  or images with fine detail.  I still see DCTV as
my main staple for anims.

Hi all, I'm trying to add bones to a tube without much success.  I want
the tube to smoothly bend at the midpoint like a Slinky, but when I
Update Bones, my tube fractures around the bones.

Could some kind soul please email me the recent bones thread, or even
better, an object that I can compare mine to.  I'm working with a
default tube - radius 50, length 100, 24 sections.  I've got 5 axes for
bones, and 10 bones subgroups.  I think I might either have the bones
subgroups assigned wrong, or my bones aren't "knitted" together
properly, hence the fracturing.  What does "knit" mean anyway (Imagine

Subject: Refraction: 2.9 vs 3.0
Date: Tue, 21 Jun 1994 12:19:03 -0400 (EDT)
From: Curcio Nicholas <[e-mail]>

Hi, all!  I just recently traced a scene with I3.0 that I previously did
with I2.9.  The reason was to use the better anti-aliasing.  Well, after
33 hrs of rendering (compared to 18 hours with 2.9) I got to view my
1280x960 trace of a glass top table.  The refraction by the tabletop was
VERY different from 2.9.  It looks like my index of ref. value was about
doubled.  I'm only using n=1.10.  Not much refraction, but 3.0 makes it
look huge!  All of the settings in preferences were the same for both
traces.  (Except for the new aa of course.)  Has anyone else noticed a
difference???  This 'higher' refraction would also explane the much
greater rendering time.

Now, on the magnifying glass thread.  (I can't resist.)  I'm an
engineering student, and I have a STRONG physics background.  (I also have
my Encyclopedia of Physics handy. :)  Light rays refract at different
angles depending on whether they are going from less dense to more dense
or more dense to less dense mediums.  For instance, if a light ray goes
from air to glass, (entering the lens) it bends towards the normal, BUT
when a light ray goes from glass to air, (exiting the lens) it bends away
from the normal or closer to the surface.  Since imagine doesn't have
solid objects, I guess it always assumes it is going from less dense to
more dense.  Some of you say you can make realistic lenses with know
problem.  I tried your techniques to no avail.   Try looking at a real
lense sometime, Imagine's don't come out even close.  The best results I
can get are by using only HALF of the lens.  Just make the other half have
n=1.00 and it looks pretty good.

Later

Comparing a solid lens to a empty shell is comparing apples with oranges.
This is pretty easy to verify:  Look through an empty round drinking
glass.  You'll see that things on the other side are a different sizedue
to the lens effect, but are still right-side up.  Now, fill the glass with
water and look through it again.  Everything is now upside down.

I haven't played with lenses in Imagine for a long time now, but I do
recall having everything flipped upside down when using a 'real world'
lens (with Imagine 2.0, I think).  I think that someone needs to model a
'real' lens in Imagine and try things out rather than just speculate.
Hmmm...maybe I'll give it a try.  I might even still have that old object
somewhere.

   I don't think so.  The .fp version is simply a 68020/68881 version, it
hasn't been compiled in order to be optimized for the 68040, instruction
scheduling, 68882 and whatever else the 68040 boasts.  It may not sound like

   Hello.  I have another question about Imagine.  I am using 2.0, and I
want to know if there is an easy way to string a bunch of poses of an object
into a convenient cycle-type object when each pose is not just a change in
orientation, but also a change in the arrangement of points; for example,
say I create a series of objects which when view sequentially would give the
impression of a wave passing over the surface of a single object.  Is there
a better way to enter this into the action editor than setting the whole
chain up as a single object entry, then changing the object path in each frame
of the action bar.  That seems so tedious.
   Also, I'll ask my other question again.  Can you do particle-animation with I
magine 2.9?
 ...with Imagine 2.9?

I don't think that Imagine is looking for a stand alone palette file,

successfully by specifying a picture that has the palette that I want.
I'd suggest saving a small brush that has your pallette in DPaint and

I'd have to disagree on this point.  It is my understanding that you get
the effect of having four interfaces only when you actually have four
faces (huh?).  What I mean is, Imagine's surfaces are only two
dimentional.  For them to have a inner and outer face (so that each face
counts as two) the face would need to have thickness.  If what you said
was true, it would be impossible to model refraction as as soon as the
ray enters the solid and gets bent, it would instantly unbend as it
leaves the surface.  As the faces are super thin, you would not see ANY
refraction.  As this is not the case (there is refraction), a lens with
two faces (one at the front and one at the back of the lens) only bends
light at two points: where the light enters the lens, and where the
light exits the lens.

Imagine doesn't do boolean operations at render time.  Real has to since there
are only the primatives to work with(if you are working with primatives).
As you said below, it works the same in Real with the B-splines(I assume
when you use B-splines, no booleans are being done)

Volume isn't so much the effect as the angle of incidence(in fact, I don't
see how volume plays into this at all)((AND I AM NOT TALKING ABOUT AN AIR
FILLED LENS)).  Remember, once inside of an object, light will travel in
a straight line.  Unless that medium isn't perfect in its content.  In a ray
tracer, the glass would be perfect.  This means that Imagines logic of
only needing to calculate at the surface holds true.

I am very curious as to how this is done.  I posted to comp.graphics.algorithms.

This was my main point.  If Imagine or Real3Ds refraction model is off a bit
(hard to say which one), so it is.  The point was that if Imagine implemented
the casting algorithm to burn ants, it could be done with surface
modeled objects instead of needing solid objects.

One reply I got on my post suggested the need to cast rays from the light
source to get "caustics".  These caustics would then be applied to the plain
where the ants were getting burned.  Not sure if I understand it completely,
but I suspected that casting rays from the camera to the lightsource and
still burning ants would be tricky at best.  Can you get the programmers of
Real to give you a clue as to how they did it?

(if anyone wants us to take this offline, just shout.  I'm not sure how many
people are interested in this)

And one last thing, as Jude suggested, try increasing the number of polygons
in the lens in Imagine.  Maybe they(the two images) will look more alike.

From: Kelly Petlig <[e-mail]>

Theoretically someone could add their own RNGS iff chunk to each Imagine
texture with some sort of patch file.  Unfortunately someone (the
programmer) would have to get all the practical limits from the manual (or
readme file) and put them in the RNGS database.  A quick glance at the
Forge database only shows the "loading defaults" for the textures, not the
ranges.  This does seem slightly redundant as the textures themselves
also have defaults ... but it does allow easy changing by an end-user.
So, the patch would have to set the color ranges to 0..255 and maybe
there is some way to "notify" the color window that this is a color.  The
patch would have to set the fade values and the like to 0..1, and the
rest to logical ranges also.  (I'm rambling a bit)  I think Steve should
publish the RNGS chunk somewhere (maybe upload it to aminet).  I haven't
been able to get ahold of him through E-Mail (Apex address) for almost a
month, hopefully he's still reading this.

One other note, I have in my archives (Ok, on my BBS) the texture and
objects format for Imagine 3.0 in "PC" cr/lf format.  If anyone wishes I
could e-mail them a copy.

Localized reflections will probably work. I guess I forgot this feature.
It wasn't documented in 2.9 and I haven't played with 3.0 much.
Still, it would be nice to have the Genlock sky option still there.

Subject: Cloud formations
Date: Tue, 21 Jun 1994 18:10:36 -0700 (PDT)
From: Kelly Petlig <[e-mail]>

Someone (I can't remember who) was asking about how to make fractal cloud
formations for use in Imagine.  I have a suggestion that may or may not
work for your application.

First of all, Imagine doesn't seem to "shade" fog objects ... so the
bottom of a cloud doesn't get darker than the sides or top.  This may
look OK if the clouds are few, as the land will reflect light to the
bottom of a real cloud, but if the entire sky is cloudy the clouds should
be darker on the bottom than the sides or top (you probably won't render
the top, so it may not matter).

What I did was go into VistaPro (everyone has it, right?) and make a
random landscape, set fractal to four or eight and do it as "island".
Set sea level to about how you want the cloud percentage to be (in other
words, make water level high for fewer clouds).  Then enter -1.0 in
VScale, to make a negative landscape.  Now you can do yet another sea
level, but this would be for the maximum variation of the cloud thickness
(keep reading if I lost ya).

Background info:  Clouds usually sit in "ranges" of altitudes, although
thunderheads usually go through several ranges.  By setting the upper and
lower sea level, the clouds still appear to have a top and a bottom to
them.

Save the clouds as an Imagine object (set your poly to 2 or 4 ... 8 for a
quick and rough test)  Ha, now comes the tricky part:  VistaPro saves the
landscape as 256 separate objects, you need to combine them all!  If you
saved the landscape with poly at 4, it may not be a problem.  With poly
at 2, there may be too many points to join ... for now.

In Imagine, with the landscape loaded, pick a handful of objects and join
them.  At this point, you can either add a plane on the top of the
landscape just a few units higher than the highest points, or you can
mirror the object on top of itself.  If you want to mirror it, try
deleting all the points past a certain level (the "top" sea-level) and
then extruding it (using "mirror")

I have not tried this, and it really isn't meant as a tutorial, just a
"hmm, why haven't I thought of that" jump-start.

Ahh, yes, I dare say I have a bit of experience in this.  Since Imagine
doesn't have alpha channel support (3.1 maybe?) yet, you really can't do
that.  Here's a work around ... render your image with no anti-aliasing.
Looks jaggy you say?  If the other video source is a collection of
stills, you can do the following:
Scale images to double size.
render Imagine pics at double size, no anti-aliasing
combine images
halve images

simple, eh?

You can try doubling the width only, but you'd have to change your
Imagine aspect ratio, etc.  I usually just go for the double route.

         OF COURSE!  That's why we LIKE to render.  The challenge!  And, of
     course, we like to find sneaky alternatives to emulating
     real-world physics otherwise, we'd have all taken up photography
     and had plenty of pictures with nice reflections, shadows,
     highlights, refractions, even inter-object 'radiosity' effects.
    Seriously, though:  the suggestion of a prismatic global reflection
    sounds like a real good idea to me.  I tried to make one using two or
    more of Impulses 'Angular' texture mapped onto a disc-shaped object
    within a certain 'subgroup' of the object.  Seemed to do the trick but
    I imagine that it wouldn't look as good animated as would the global
    raflect map.  Ah, perhaps rotate the angular texture about as it
    changes from one set of settings to another.... anyone?

Subject: LENSE
Date: Tue, 21 Jun 94 23:55:03 -0300
From: [e-mail]

Ok guys & gals...I've been sitting idly by reading all the post regarding
making a lense in Imagine it Real 3D, and how each handles light as it passes
through it.

SOme people mentioned that Real 3D uses CSG "solid" objects and treats them
like solids...(whatever that means).  They also compared POV's CSG objects as
also creating realistic lenses because it's objects are treated as being solid.

Well, POV's objects are treated as solid when they are being created and when
they are CSG'd.  However, when they are traced, only the surfaces of the
objects are known by the renderer...just as in Imagine.  I assume the same is
true for Real 3D...only because to calculate every single position within an
object would take forever to render.

The noticeable differences in lenses rendered in Imagine & Real 3D most
assuredly come from differences in the lense construction, as well as
differences in the rendering engines.  If you want to create better looking
lenses in Imagine, try using more triangles, and try upping the number of
internal reflextions allowed in the preferences editor.

Don't think you can, I use to use the color I thought was closest to what
I might be genlocking over, but you can't do that now. So the best I can
give ya is to turn of anti-aliasing. or set it to a minimum and use your
genlock to fade those colors down a bit..

t34dos is a series of PC executables based on the Amiga TTDDD package.
Essentially, it allows you to convert Imagine TDDD format objects to a textual
format, easily editable by hand or by computer, and change the textual
descriptions back into Imagine TDDD objects.  Could be great for minor
modifications, computer-generated objects, etc.

TTDDD stands for "Textual Three-Dimensional Data Description."

Well, since you asked for _anyone_...

I took a disastrous try at this once.  Absolutely ugly.  I decided I'd just
digitize stuff from now on, but since then I got _an_idea!_

Looking at my CD collection, I see that there's a gray-looking disk, with a
plastic coating.  When I move the CD, I get angular-looking ranges of color
that move in opposite directions around the CD.

If I were to model this, I'd try making a gray, partly-reflective CD disk,
with two or three thin, transparent disks on top, and a plastic,
non-refractive, lightly reflecting disk _enclosing_ the whole bit.  To each of
the thin, transparent disks, I'd give one or two angular textures, and I'd set
up a second object to morph the textures in different directions.

This would be really easy if Imagine did diffraction, but this is as close as
I can get, I think.  If you're really desperate, give it a shot.  Hell, I
might try it tonight.  I like that comment someone made on "less speculation,
more effort."

Just my two cents.

Hello!

    I am (was?) a C= developer and I've had 3.x up and running on my
A3000 for many months. Imagine 2.0 and 3.0 work just fine on it as well
as VistaPro 3.05, ADPro, and DeluxePaint 4.1. The DCTV stuff works fine
except that I have the old 1.0 version of the software and the screen
must _not_ be overscanned or you will not be able to see the image
screen, just the toolbar. The only problem with Imagine is that if you
click on a quickrender screen (rather than type esc) then the system
will slow to a CRAWL and hang for about 45 seconds. This mostly happens
when I run arq, but I haven't really tracked it down yet. Everything
else seems to work fine. Drop me a line if you have any other questions.

> Rain. HELP!

well for rain you need to rotate the Z axis of the texture so that it
faces away from what polygons you want it on, so if you had a defualt
plan you you would have to rotate the the plan X 90 and then rotate the
axis only back to 0, then you would load the texture onto it and it will
be facing the right direction Z would be up. To fit it to the plan so
that it rain on all of it, as rain only works within the distance of your
axis size box, you would select rain in the tecture box and select info
and then Tranform Axis, now set the size of x, y,and z to 50.00. Then go
and set the texture settings to what you like.But to animate it you need
to set Dist Travelled to 0.000000 and then save this object as rain.obj1.
Now go back in the texture and set the Dist Travelled to .999999 and then
save this object as Rain.obj2. Now after setting up a project
load Rain.obj1 in the first frame of the animation in the Action Editor
and then load Rain.obj2 in the next frame buy clicking it once and then
moving to the last frame and click it once. When you get the requesters
for the objects you may want to use Discontinuous Knots for both objects.
The beam me up texture would work in a similar way except the Z axis is
not as critakle as with the rain, its as simple as that..the .999999 is
actually only if you want it to loop so you could actually make the rain
fall faster by adding more of these object sequences together during the
animation length. If you just need it to sprinkle throught you could
probably set the Dist Travelled in the texture to 1.000000.

Hmmm? when you say 24 sections, do you mean Verticle sections or circle
sections..I think you may need to add some verticle sections. It won't
bend an actual polygon which sounds like what your trying to do..you need
to make 11 verticle sections and size the section apart and then set
your axis's starting from the second section up, every other one so that
your tube will bend at these points. Then make your subgroups for all the
sections. Just so I don't have to go threw the whole process, if you want.

From: Stethem Ted              5721 <[e-mail]>

  3D Studio has motion blur, field rendering, alpha channel, soft shadows,
extremely good anti-aliasing, almost total .DXF compatibility, runs under
OS2 and Windows, is networkable,  promotes to higher resolution screens
dependant on the graphics card, uses JPEG, Targa, GIF, FLC (animated) for
brushmaps and textures (uses brushmaps to create textures), uses any size
bitmap for backgrounds regardless of the render resolution, tweens morphs,
has camera sizing with actual lens sizes (as well as multiple cameras),
multiple 3rd party routines for single point dynamic particles, explosion
and other effects,  has a built-in Materials editor that renders preview
textures about 10 times faster than Forge and renders scenes about twice as
fast as Imagine (on equivalent clock speed platforms).  It is being used as
the main rendering tool for the games Rise of the Robots, 11th Hour plus at
least a dozen more.  The price has been reduced to about $1800.
  Imagine is primarily a moderately priced artists rendering tool, not a
high-end CAD rendering tool.  As such, it is probably unrealistic to expect
the same performance with all the features at the same price.  However, 3D
Studio performs many additional functions that Impulse has said they have
found "impossible" to do without severe time penalties,  while rendering at
twice the speed of Imagine (of course render time is dependant on several
variables but this comparison is with equivalent scenes, objects and
additional effects).  There is more than one way to skin a cat and they
don't all have to be messy.

Well at $1800 dollars it is out of my price range, and so does not exsist.
I can't understand why people keep posting this sort of message to the IML.
Fist Imagine runs on  amiga and Dos boxs. I own only an Amiga, and could by
Lightwave standalone for half the cost of 3D studio. LW's credits make 3D studio

look pretty sick for the money. Does 3D studio Ray Trace? I have seen things
 done in Imagine that really stand up to most of the other renderers. It boils
down to the users creative ability. All programs have strength and weak points.
At a recent LW users group a very skilled 3D creator stated it was not as user
friendly as LW, and Imagine. One could compare 3D studio with Renderman also,
but to what end. I use the Amiga and have all types of support software. How
many 3rd party programs are currently running under OS2. Imagine 3.0 offers
many features for the buck, and I doulbt that any other package offers this
balance of features for the dollars spent. As for high end cad rendering,
How do we define this? My first thought is many that post these comparsions
don't really know enough about Imagine to get the best possible results from
it. I read most of the graphics mags(many dos related) and so see the reviews
of the other 3D products. recently I saw an article on a soda can ad done
with 3D studio. nice but nothing really special. Does 3D studio support
procedural textures ? If not then it is sorly lacking. LW has them coming
and bitmap wraps are nothing new. I can scan at 800dpi 24bit and save
the image as .tiff,bmp,gif,targa,and many others. Of course I use ADPro
to convert to IFF24. I try to keep all my images in one format anyway
so listing a bunch of formats a program supports does not impress me.
So we all know that many programs vary greatly in features, and some
feature are more usefull than others. Imagine's Procedural textures
mean more to me than Motion blur(There are AREXX programs that will do
this as a post process). BTW many of the finished products we see have
had post processing on one kind or another done. Very few go from
render to finished products. Forgive the typos ect, Im at home and very tired.

Take heart. If you REALLY want to get depressed, REALLY, just price one of those
 SGIs with a Reality Engine and the R4400 to back it up, tack on a minimum of 64
 mb memory and a two gig drive. NOW, lets buy some software. These prices would
shock Mac users. A good SGI rendering package will cost you what most people pay
 for a car. That's without the maintenance aggreement. If time is money, most of
 us have a LOT more time than money. Sort of like complainng that your Miata jus
t can't keep up with a formula 1 race car. Different league, different game. Som
etimes their paths cross but mostly not.

For what it's worth, if the Amiga is still being developed and manufactored in t
he years beyond 2000, it will probably out perform your SGI of today, but not th
e SGI of its day.

Subject: Aztec to Imagine
Date: Fri, 24 Jun 94 18:56:54 CST
From: Jeff Niebergall <[e-mail]>

To those of you that have asked me to upload the Aztec city object
I must report bad news. At the present time my internet connection
only allows ascii transfers. I have tried every way I can think of to
upload this thing and I am stumped. I would try sending it uuencoded
to some one who could upload it but my experience with uuencoding
is limited. The encoded file is 1.1 meg by the way. What is the
max size a ascii mail msg to send it as part of one? If need be
how do I break up the complete file into smaller one that can
be sent?

(this part is Imagine related at least)
The other option is use what I did to convert it. Accutrans 3D.

Here is the contact and pricing for it.

The object is very impressive but be forwarned that you need more
than 20MB of ram to render it or VM.

  Actually, things may develop faster than you think.  Sega, Nintendo, and
Sony all have next generation consoles in development and will be previewing
them at the Consumer Electronics Show this week in Chicago.  The Nintendo
console will actually use a Silicon Graphics R4400, possibly a WindowsNT
operating system, and is expected to cost about $250 (that is the price
being promised right now).  And from an article in EE Times about the new
Sony machine:

  Sony Corp.'s month-old Computer Entertainment division demonstrated a
prototype of its 32-bit Playstation videogame system last week and revealed
that the heart of the machine is a single chip from LSI Logic Corp. that
integrates the ASIC vendor's R3000 MIPS processor core, graphics
transformation engine (GTE) and video decompression engine (VDE).
  Production of the half-micron, 3.3-V, 1-million transistor Playstation CPU
is now ramping in Japan and Santa Clara. The chip has a multitasking
architecture that allows for simultaneous operation of the 34-MHz CPU, GTE
and VDE, which combine for a total of 220 Mips.  When the performance of
Sony's separate graphics processing unit (GPU) is added in, the Playstation
is rated at 500 Mips, according to Sony.
  Brian Halla, executive vice president of LSI's Products group, said the
GTE can calculate up to 1.5 million transforms/second.  That enables Sony's
GPU to generate 360,000 polygons/second, Sony said.  Using JPEG compression,
the system can deliver 30-frame/s video.

   While a lot of people denigrate video games, it is a well known fact in
the electronics industry that video games push the envelope of technology,
are able to change more rapidly than desktop computers,  and bring the price
of once exotic technology down to the consumer level.  In case you haven't
noticed, 3D animated graphics is very hot in video games.  If you consider
that a fairly complicated 3D object, maybe 60,000 polygons, takes several
minutes to render on your current platform, and then consider that the Sony
console will be able to render 60 times that amount (360,000 polygons) in
one second, then you should be able to see where this is going.  The current
3D rendering methods on desktop computers rely on software calculations for
the rendered image.  These new, low-cost hardware rendering engines will
eliminate the need to do all of these calculations in software.  Already,
3DO and Atari Jaguar are being redesigned to become plug-in boards for PC's.
 These video game consoles will become incredibly fast  graphics accelerator
cards for PC's.  Modeling, at least without a digitizer, will still be
mostly manual but with almost instantaneous screen redraws and near
real-time test renders, will be speeded up considerably.   So, the era of
desk top near real-time ray tracing may not be that far off and not that
unaffordable.

Take heart. If you REALLY want to get depressed, REALLY, just price one of
those SGIs with a Reality Engine and the R4400 to back it up, tack on a
minimum of 64 mb memory and a two gig drive. NOW, lets buy some software.
These prices would shock Mac users. A good SGI rendering package will cost
you what most people pay for a car. That's without the maintenance
aggreement. If time is money, most of us have a LOT more time than money.
Sort of like complainng that your Miata just can't keep up with a formula 1
 race car. Different league, different game. Sometimes their paths cross but
mostly not.

For what it's worth, if the Amiga is still being developed and manufactored
in the years beyond 2000, it will probably out perform your SGI of today,
but
not the SGI of its day.

Hey Stethem, et al,

    Your post made my mouth water.  And I have to say that I think we
with our 24bit Imagin-ations are already equal to if not superior to
Silicon Graphics in quality of imagery.  I have a friend here in Huge
Eeen named Paul Scott who works with SGI machines all day long, and he
was the first high-end user I got to admit--and hell, not even admit, he
volunteered the statement--that 24bit is 24bit, and he'd seen stuff done
on our Amiga's that was at least as good as the best they'd ever done.

    What we lack in hardware/software capability, we make up for with
ingenuity--and patience.  That's the only place we fall way behind,
SPEED.  And with the Screamer, or Raptor or SpeelWeenie or whatever
NuTek's calling that mips monster they're unleashing, combined with
existing Toaster capabilities, and hooked to the new Flyer--hey y'all,
beta versions are already on their way to Oregon--I think we're about to
pass SGI even in the speed department.  And though prices are going to up
the ante a little even for the most serious 'hobbyist's' budget, they'll
still be beans on the dollar compared to what it costs to enter the SGI
realm.

    Excuse these overlong paragraphs, but listen:  the twenty-first

From: "Randy R. Wall" <[e-mail]>


 > I would like to know how tu use the animated textures such as BeamMeUp and

 well for rain you need to rotate the Z axis of the texture so that it
 faces away from what polygons you want it on, so if you had a defualt
 plan you you would have to rotate the the plan X 90 and then rotate the
 axis only back to 0, then you would load the texture onto it and it will
 be facing the right direction Z would be up. To fit it to the plan so
 that it rain on all of it, as rain only works within the distance of your
 axis size box, you would select rain in the tecture box and select info
 and then Tranform Axis, now set the size of x, y,and z to 50.00. Then go
 and set the texture settings to what you like.But to animate it you need
 to set Dist Travelled to 0.000000 and then save this object as rain.obj1.
 Now go back in the texture and set the Dist Travelled to .999999 and then
 save this object as Rain.obj2. Now after setting up a project
 load Rain.obj1 in the first frame of the animation in the Action Editor
 and then load Rain.obj2 in the next frame buy clicking it once and then
 moving to the last frame and click it once. When you get the requesters
 for the objects you may want to use Discontinuous Knots for both objects.
 The beam me up texture would work in a similar way except the Z axis is
 not as critakle as with the rain, its as simple as that..the .999999 is
 actually only if you want it to loop so you could actually make the rain
 fall faster by adding more of these object sequences together during the
 animation length. If you just need it to sprinkle throught you could
 probably set the Dist Travelled in the texture to 1.000000.

I would be willing to try having you send the whole thing to me in one huge
uuencoded chunk.  PLEASE contact me directly by email so I can tell you to
what account to send it, as the account from which I'm posting here is
unable to handle that volume and would bounce the whole mess back to you.

Hi Dave,

I've been checking out your bug, and found some interesting stuff.

The blank sides occur even if you put the Altitude map on directly,
without changing from a Color map. I got it when rotating the
Perspective view to the left or the right.

It's not an object construction bug, but rather a Perspective Window
problem.  You can see that all sides are correct by rotating the
object without changing the Perspective view. Also, the blank sides
occur irrespective of the orientation of either the object axis or
the brush axis -- it's always the side viewable when rotating the
Perspective view to the left or right.

It doesn't occur 100% of the time.

Interesting stuff!

Personally, I don't believe that Imagine is optimized for the 040 at

the 040 was around...  Besides, from what people have said before,
that have to turn the writeback caches off on the 040, or Imagine will

Does any one has a solution to this?

When applying the brush with ordinary color mapping I can't see any seams

As I recall, when Imagine 2.0 was released, there was a huge increase in
speed for '040 owners, and only a slight increase for '030 owners.  How
huge?  I seem to remember something like 2 to 3 times the speed.  The
only version I think that had to have the copyback cache turned off was
TurboSilver ... Lightwave worked with '040s but not with 2.0, so
Lightwave users had to hack their '040 software to run at 1.3 and I at
first copyback had to be turned off with everything while loading.

Official word is "It's been '040 optimized since 1.0"  Take that how you
want.

In the attributes requestor, save the attributes to ram: after setting up your c
olor map the way you want it. Now load the attributes back in immediatly. You no
w have a second color map defined. Enter that map and change it to bum (altitude
), but do not edit it. The altitude and filter maps must have identical settings
 to the color map when you are using tiles. Hope this helps.

Subject: EGS Spectrum & Imagine
Date: Mon, 27 Jun 94 08:16:00 PDT
From: Stethem Ted              5721 <[e-mail]>

  To whom it may concern:

   Several times in the past, people have left questions about how various
graphics boards worked with Imagine and which was the best one to get.  It
seems that these messages never got many responses and I was always one of
those people that would have been interested in hearing more about this.
  Well, the price of the GVP EGS 2Meg Spectrum board came down a couple of
hundred dollars so I got one.
  I am finding that Imagine screen redraws with the Spectrum are about twice
as fast as with the normal Amiga ECS.  This is really nice for modeling and
editing.  At this time, I don't think there is any increase in rendering
speed and I wouldn't expect there to be one.  Also, the Spectrum will
promote Imagine with no problems so far.   I have a 1950 monitor so 800x600
is about the maximum for me but it is very workable (and so much better than
600x400).  I have only had the board over the weekend so this is no in-depth
review but I am very excited and happy with it so far.  Also, this is not an
endorsement for the Spectrum, just some info you might find useful if you
are looking for a 24-bit graphics board to enhance your Imagine work.
  The only problem I had is that Creative Computers is shipping the board
with EGS V6.0.  I had several nerve-wracking hours installing that and
eventually being locked out of my computer and having to boot from Workbench
floppies to get any kind of screen back before remembering somebody saying
EGS V6.0 is full of bugs and there was an EGS V6.2 out.  So, if you get this
board and find it is coming with EGS V6.0 install disks, don't even try to
use them.  GVP has the V6.2 available on their BBS for free downloading on
the first log-in.  BTW, EGS is great when it is working right.

There are several bitmap viewing utils available in various places.
Specifcially VPIC, DISPLAY, and CSHOW are among the most popular.  They
support a wide array of graphic cards and should do what you need (ie

This sentence wasn't properly worded ... sorry for those who took it a

I can only say what I've been told, and if others don't believe me, don't
take it out on me.  I didn't own Imagine 1.0 or even have an '040 until
2.0 was out, so I don't know anything about how it was programmed.

Thanks for the tutorial. Looks good as long as two spotlights doesn't
intercept, because then the intercepting area goes black and not whiter. Looks

Any way around this?

Yes, as this article was originally written for Imagine 2.0 and some one
wanted me to send it to them I did, and made the mistake of not
conferming how well the effect Controlled Falloff had on the light, in the
lights requester for 3.0 when I added this part to the tutorial. It does
work but not quite as nice as Diminishing Intesity as there seems to be
more Falloff than Diminishing Intesity gives, and makes it harder to set
the Liner texture to the falloff length.

I have sense been trying to get some spotlights done to send to the net and
found this in the proccess. Sorry for my error, but to correct
it all you need to do is use Diminishing Intesity instead of
Controlled Falloff. This will give you the effect you want. Also make
sure that you set Ambient in your globals to about 80, 80, 80 as this
will help stop Imagine from rendering black within your beam and try
setting the Filter of the Bright cone to 180, 180 ,180, or 200, 200, 200
as this will help as well. Sorry for any trouble this may have caused
you. I have also found that these spotlight don't work as well as they
seamed to have in 2.0 and 2.9. Not sure why but they seam to get some
weird dithering  with the Controlled Falloff and Diminishing Intesity
setups when hitting the ground then when I used them in 2.0 & 2.9. Its
not a perfect spotlight but the best I have come up with in Imagine that
will also work in fog.

I am also not sure as of yet if it
is possible to get the Softedgelite to work or GlobalHaze textures, as I
have had trouble getting them to look properly, and have not had the time I
would like to devote to experimentation of such a spotlights. I have not
given up but, am not making great progress at the moment do to other
pending projects. If any one else has time for this type of
experimentation I would appreciate any input. THANKS in addvance.

My name is Daniel Bracher and I study computer science in Federal

Imagine since Turbo Silver 3.0 (that's a joke). I really love
Impulse. I'am starting to program CG in C++, and I have some
information in graphic formats and CG routines. So if some wants to
exchange some info, please feel free to contact me. After the
University finishes the period, I'll organizate my routines and list
them to you.
I have some impressions about all I've read in IML.
- I think that Impulse doesn't make Imagine with 'Amiga Look' because
to get the easiest way to port to PC (argh ...). Besides, CBM is a
task held company.
- Imagine on SGI ... Impulse has to remake it's interface from the
ground. It's very dumb comparing to Wavefront, TDI, Alias, etc ...
And add a lot of features on Imagine, too.
- Why don't Impulse hire Steve Worsley to write Imagine manuals.

So back to rendering

BTW, I am attending to a course in my university ministrated by Allan

I worked with 3DS and I don't know what you mean with shitty rendering.
The quality you get is great and it is MUCH (!) faster than imagine
(and not half as buggy)!
You're right about the slice problem, but it is a little better than
in imagine, because the first boolean operation works almost every
time (in fact I experienced no time the first one caused an error).
Biggest advantage of 3DS: If you want a good looking scene QUICK,

Regarding the Aztec City DXF file....I have downloaded the file from AutoDesk's
forum on Compuserve.  The descriptive file and the text file were very
promissing.  Upon unzipping the file, I discovered that it was not in DXF
format but rather in AutoDesk's DWG format.  This may be the problem that many
people are finding.  To date I have found no converter or any application that
will read DWG.

With regards to the DXF to 3DS converter that Syndesis included on their disks,
and on compuserve...it's incredibly efficient.  I have been able to
successfully convert AutoCad DXF release 12, AME SOLMESH files.  And if you
never ran into that format...you're lucky.  I have found nothing else that
would accurately read it.

"Imagine's DXF import is broken."  Give me a break....no program handles every
aspect of DXF....including AutoDesks 3D Concepts (and they wrote the friggin
DXF "standard").  There is a route that you can take to convert most any DXF to
a DXF format that will be read by Imagine.  But no-one tries.

Subject: Imagine Mapping Bug
Date: Tue, 21 Jun 94 23:59:46 PDT
From: [e-mail]

Here's a funny little Imagine bug.  It's in Amiga versions 2.0 and
3.0 (I never noticed it before) but not in PC version 3.0.

1.  Make a cube.  Add a 1 x 1 plane primitive and extrude using the
default settings.  You could use the default plane settings too.  In
fact, it even works if you make a cube by sweeping a bracket.

2.  Set the cube's axis in its center.  This isn't necessary but
results in more uniform brush mapping.

3. Select Attributes and turn Phong off. This is important!

4.  Add a brush map, Wrap X and Wrap Z. Use defaults for all other
settings.  Use a nice uniform bumpy image.

5.  Change Perspective view Angle so that you're looking down at the
upper front right corner of the cube.  You can see front, top and
right sides.

6. QuickRender and note expected results.

7. Change the brush map to Altitude. Leave all else the same.

8. Render again. Note right side is blank (!).

The only way I was able to fix this was by deleting all of the
cube's faces and edges, then re-connecting the remaining points into
new faces--pretty easy.

Guess I'll drop a note to MH.

Well, If I understand what you want, you could make several morph groups
of your wave and other objects, and make time line bars between them in
the action editor, Then you would only have to morph the one group. The
most important thing to remember is when you make the object group is to
keep all of the objects in the same order, you can check this with the
FIND command. And also when you move the points of an object in this group
you must leave the axis in the exact posision and alingment as the first
group or you will get unexpected results. If you have textures or wraps
on this object you will have to calculate any rotations or movement you
will do to the points and move the texture/wrap axis accordingly to match.
This is how I made a scuba diver, jelly fish, shark and stingray as well
as other assorted fish swim in an animation I did called Treasure Hunt
that is on the Amigamations Videotape. I had to morph all of the
different movment of all the groups..Wish we had bones and States back then..

The seam in the tileable altitude map is NOT a bug.  Imagine adds a 1 pixel
border (color values 128,128,128) to the brush when tiling it.  That is how it

Hi All!

Wow, not a lot of mail these past couple of days.  Are you guys on
vacation , or something (you don't have to answer if you are :) ?

As no one has responded to my lighting bug, here we go again:

The bug would appear to be when you choose a rectangular, parallel
lightsource.  In detail, add an axis and make it a parallel, rectangular
lightsource.  Also, set it so it doesn't flare.  Make the x-axis
something like 20 and the z-axis 40 (ie: rectangular).  Save it off.
Now create a ground with a dark colour, and save it too.

Now goto stage and load in the axis and ground.  Place the axis above
the ground with the axis' y-axis pointing towards the ground.  Move the
camera so that it is pointing at the ground where the light hits.
Render.

Here's what happens to me: along one of the lights axis (I forget which
one), the light on the ground is not constrained, but extends to
infinity (as if the size of the light along that axis is infinite).

After playing around, I found that setting the light to not flare causes
this bug.  If you do set the light to flare, then the light behaves
normally.

Anyone else confirm this?  Mike?  Scott?

If they chose to implement it that way, or not, it's still a bug, because
it serves no purpose, could be easily supplied by my own brush map, and I
get no choice to rid myself of the unwanted border.  A bug is a bug by any

I was able to place an advanced order for the 3D digitizer with Impulse. They st
ated that we will have 30 days from the date of their next news letter mailing t
o order the digitizer at the $500 price. That means less than 30 days from the t
ime you get the news letter. Impulse seems willing to take advanced orders and t
hey stated that they will not charge your card until the product ships. They als

s same unit works on both platforms). If you decide to place your order now, you
 should confirm what I've said here, and not go on my word alone. This is not an

There was supposed to be a doc on the disk about the new textures.It was
neither installed on my system nor is it present on any of the disks...

Anyway the Spike.FX makes your object go all spiky by pushing out points
in a random pattern(that can be repeated),it'll do this in a number of
cycles if you want.Baloon.FX sort of scrunches up your object and will
return it to it's original shape if you want...By scrunches I mean like
the effect you get when crushing up a paper bag or something similiar.


Hope that helps,hey why not just experiment with them,that's what
working with Imagine is all about...usually. :)

Hi,

At the moment I am looking into buying a 3D package for
animation. Imagine is one of the candidates, but I need more
information. Could someone suply me with the address and
faxnumber of the makers of Imagine (Impuls?).
I am a kind of superuser in a group of anthropologists. Some of
them need short films of for instance balls rolling through a
chamber. We have got some 3D software on a Mac (Swivel,
Stratavision and LifeForms), but even something 'simple' like a
ball rolling is impossible to do (easily) with it.
There are 4 programmes that might fit our purposes that I know
of: Imagine, 3dStudio, Real3D and ElectroGIG. The platform we
will probably be using is PC, preferably Windows. If there are
people on this list who have extensively used more than one of
the aforementioned programmes, I would greatly appreciate it if
you could send a comparison.
These are the three main things I am looking for.
-Ease of use: some rather computer-illiterate people should be
able to use it
-Modelling speed: I do not want to animate a rolling ball by
rotating it frame by frame. Rotate and Boing effects like in
Imagine would be great
-Future: We are not sure yet if we will be using the
possibilities of 3D software in the future (visualisation, etc.),
so it should be able to do more than just the two aforementioned
things.

Please keep in mind that I am not a subscriber, so send your
answers to me personally ([e-mail]). If there are no
objections I will send a digest of your answers to the list.

Thanx in advance,

Subject: Imagine 3.0 for the PC
Date: Fri, 1 Jul 1994 09:24:03 -0500
From: Frank Kang <[e-mail]>

I'm considering purchasing Imagine 3.0 for the PC after having used
version 2.0 that came with the 3D Modeling Lab book.  One thing that
is not clear to me is the video resolution 3.0 supports during
editing.  2.0 seems to support only VGA and I find that a bit
hindering.  Does the current version support higher resolutions -
ideally at least 1024x768?

If not Imagine, I'll probably get Caligari Truespace.  That depends,
however, if it supports ray tracing.  It wasn't clear from the
crippled demo I have whether it does more than scan line rendering.

Subject: No lensflare toggle bug

From: "" <[e-mail]>

Hi,
   I've also just encountered the bug with the no lensflare button in the
lights requester.As has been mentioned on the IML beforehand when you
activate this all your lights work at full strength,even if you have
diminish intensity set...and even if only one light has this flag set all
the lights are affected in the scene!

I hope Impulse can squash this bug quickly by the time they redo the
global lensflare FX.
