Subject: [IML] IFW: Simple Question
If the dust from this dang tornado ever settles could someone answer a simple
question?
How do you edit points from two separate objects, at the same time?
I have a curved road. It was created in autocad because thats where the
survey data can be imported into. The curve in the road is not smooth enough
though so I brought it into Imagine to fracture and edit. Its a much quicker
operation in Imagine than autocad.
The asphalt is one object and the white skip lines are another object. But
like a road they are one seamless mesh. I need to move the points of both
objects at the same time to keep the mesh seamless. If I join them together I
will loose the uniqueness of the two groups.
I know there is a simple solution. Its embarassing to be at newbie status
when you have owned a program for so many years.
Any help would be greatly appreciated.

Well, I scarcely dare offer help, but this is my idea: move the white
skip lines
temporarily off to the side of the road, so that there is some space
between them.
Dump the attributes of the skip lines to a dummy plane object. Join the
road
and the skip lines, then edit. Then split off the skip lines again, and
reapply the attributes. Finally, replace the skip lines to their
original
position.
Alternatively, can subgroups supply the differentiation you need? I'm
guessing that you need the two objects so that you can have full control
over the attributes. Subgroups offer a subset of attributes, but you
know
this.......
The point I'm having a hard time visualizing is "two objects, one mesh".
My BVRE is not working - Charles, if I whack it against the wall, do I
void the warranty?
It will be interesting to see what the best answer is.

You may not need to edit both objects at the same time. I would
assume that your road object is not going to change so all you
do is pick the lines object first and then using shift key
select the road object. Then go into edit points mode and while
you will not be able to edit the road object you will be able to
see the vectors of it as you edit your lines object. This is a
useful feature and one that many people may not know since when
you go into edit points of an object all other objects
dissappear unless you do it this way.

Thats it! Thanks Clae, it works great.
I did'nt realize that when you joined two objects the subgroup info did not
get lost.
Several others responded to this post, S.G. good idea but I do need to edit
the vertices (points) of both objects at the same time. I dont think I could
get them back together cleanly if they were not edited at the same time.
Martin said; "The point I'm having a hard time visualizing is "two objects,
one mesh"."
The animation work is being done in Wavefront software. When the road object
was translated from Wavefront the object grouping came into Imagine as two
separate objects. So you are right Martin it is no longer one contiuous mesh.
I simply wanted to fracture both objects, smooth them out and transfer them
back into wavefront. I did not know how to join them while keeping the
subgroup info intact.
Then when transfered back into wavefront I would have had to meticulously
separated the skip lines from the road. Because they would have been one
object with no grouping. Ah the wonder of translators.
If this makes any sense your BVRE is quite a wonder.
So why am I using Wavefront when I could be using Imagine? One simple reason,
wavefront can read in an ascii text files to be used as motion input.

First, the serious answer, then a bit of humour.

There are many possibilities, depending on the specifics of your
situation. If the winding road remains horizontal all over, you can do
the following:
- If need be, raise the white line object a few units, to be able to
select its faces later on.
- Select all road faces and make a subgroup called ROAD. This is easily
done with the Drag Box in the Front or Side view.
- Select all white line faces and make a subgroup called LINES.
- Join the two objects, picking the road first.
- You'll need to reapply attributes to the LINES faces, but since there
is a defined subgroup, it's easy for you to do so, and apply any
textures or colors to that subgroup only.
- Finally, in Pick Points mode, pick all points from the LINES subgroup
and lower them back down to their former position, barely floating above
the road.
Since the road and white lines are now a single object, you can easily
edit all their points simultaneously.
If the road also runs up and down hills, simply raise the white line
object, in the beginning, high enough to clear the highest road point.
You'll end up with entirely separate sets of points in the Front and
Side view, and will be able to pick all white line (or road) points or
faces in one stroke of the Drag Box.

With apologies to EasyFlow (*), here's the actual license agreement for
Blaq's Virtual Rendering Engine. This should answer any question you may
have.
________________________________________________________________________
Bloodthirsty License Agreement
------------------------------
This is where the bloodthirsty license agreement is supposed to go,
explaining that Blaq's Virtual Rendering Engine (BVRE) is a copyrighted
package, sternly warning you not to pirate copies of it and explaining,
in detail, the gory consequences if you do.
We know that you are an honest person, and are not going to go around
pirating copies of BVRE; this is just as well with us since we worked
hard to perfect it and selling copies of it is our only method of making
anything out of all the hard work. For your convenience BVRE is
distributed on a non copy-protected diskette and you are free to do what
you want with it (make backups, move from machine to machine, etc.)
provided that it is never in use by more than one person at a time.
If, on the other hand, you are one of those few people who do go around
pirating copies of software, you probably aren't going to pay much
attention to a license agreement, bloodthirsty or not. Just keep your
doors locked and look out for the BlaqSoft attack shark.
Honest Disclaimer
We don't claim BVRE is good for anything - if you think it is, great,
but it's up to you to decide. If BVRE doesn't work: tough. if you lose a
million because BVRE messes up, it's you that's out the million, not us.
If you don't like this disclaimer, tough. We reserve the right to do the
absolute minimum provided by law, up to and including nothing.
This is basically the same disclaimer that comes with all software
package but ours is in plain English and theirs is in legalese.
We didn't really want to include any disclaimer at all, but our lawyers
insisted. We tried to ignore them but they threatened us with the attack
shark (see license agreement above) at which point we relented.
DON'T LOSE THE MANUAL
That's right; don't lose this manual. Especially don't lose it before
you have read this page. Why are we telling you this? Isn't it obvious
that you shouldn't lose the manual?
That's what we thought. Then we started getting all these calls from
people saying "Hi! I'm Joe Blow and you've never heard of me, but I
bought a copy of BVRE from FlyByNite Software and now I can't find the
manual... will you send me a new one free?".
At first we were nice guys and went along with this. Then we started
getting a bit more hard nosed about it; after all it is trivial to copy
the disk but the manual involves somewhat more work. Now we had to
agonize over each request and try to distinguish between the genuine
unfortunate ("the dog chewed it up") and the merely unscrupulous looking
for free software.
So what does everybody else do? We phoned the local Chevy dealer and
told them we had misplaced the engine out of our new Camaro; that call
didn't get us much useful information. Well ... cars aren't software. We
called Borland and gave them a song and dance about losing our Turbo
Pascal manual; they said to mail a letter to their "Lost Manual Review
Committee". Wow! What a good idea. So we immediately rushed out and set
up our Lost Manual Review Committee. The Committee meets once a month.
They don't send out many replacement manuals, but they seem to do a lot
of howling, rolling around on the floor and saying things like, "Oh wow
- listen to this one".
Don't lose the manual.
Replacement manuals are available without going through the Committee
for US$147.95 each.
________________________________________________________________________
(*) This was the actual license agreement printed in the manual of a
flowcharting package called EasyFlow, and it has been part of computer
nerd lore for a long time now. I simply substituted BVRE for EasyFlow.
See, Impulse isn't the only software company who doesn't have a pickle
you-know-where!
