THE THIRD DIMENSION
Letters
-------
Dear Tony
I am trying to create controls on a border but I cannot find
the (bounding?) box that you stretch around the icons on my
border. Where is it?
Anon
Dear Mr/Mrs/Miss Anonymous
You will find the box in the very top left corner of the screen.
Simply pull it to the centre of the screen to resize it by
moving your mouse pointer to the top left of the screen, holding
your left mouse button down while dragging the box to where you
can see it.

Dear Tony,
Thanks for another great issue of our Diskmag.
I've tried out your tutorials on flexicubes and the worm object.
I am not that good in creating something decent from a flexicube,
but i made some fancy objects that could well be handled with
the setsize (x,y,z) command. So on this disk you will find two
datafiles and a soundbank for Amiga/Atari:
flex1.3wd
flex2.3wd
flexi.3sm
I used the border and colours from the Start border which i
have changed a bit to suit my needs. You will find the 'Border.iff'
also on this disk.
Best wishes from Mieke.
Well Thankyou Mieke! I am glad that you liked the tutorials.

Dear Tony
I really enjoyed using the brushes from the last issue. Can we have
some more please? As I am very new to the kits and always getting
stuck, perhaps you could go over the basics again for me sometime
in the near future please. I realise that you have done this before
but I don't yet have all the back issues.
Thankyou!
Adrian L Cunningham.
Yes Adrian! There is another sheet of brushes on this months disk.
The basics of the kits will be covered again quite soon.
Tony

I have just imported my kit 1 datafile into 3D kit 2 and every
control seems to have slowed down. What has happened? Using the
right mouse button on a control moves me as slow as using the
left one.
David Porter
Dear David
Go to the Controls menu in kit 2 and have a look at how the
buttons have been set out. The chances are that the controls are
all set to Left mouse button only. Simply alter all of them to
show Either button and everything will be OK again. This problem
seems to happen a lot when you convert a kit 1 datafile to a kit
2 one so always check the controls.

Dear Tony,
Well thanks once again for the monthly disk-mag. For a moment
there I thought you'd collapsed under the weight of committments
and were struggling to get beck on your feet!
( No chance of that Nigel. I just keep going and going...Tony)
Over here in the wild west I keeps plugging away as usual at
the old PC, the Kits (as much time as I can), and the odd flight
sim just to keep my wings.
(Flight Sims? My idea of heaven when it comes to computer leisure
time, as well as the kits of course....Tony)
Finding new evidence for my Roman reconstruction is a slow
process at the moment. I've been in touch with my friendly
archaeologist to find out what is going on, and it seems finances
have been cut and his job is now under threat. Now this won't do!
I've told him! Anyway, their usual annual publication for the
layman, detailing what has been going on over the last year, has
not been published yet - and apparently might never be. My
contact was kind enough to send me some up-to-date information
and I'll be working on that over the coming months, but it
saddens me greatly how society doesn't seem to care about its
heritage unless it can build a theme-park around it, or dig it
up and build housing estates on it. I know all the arguments, I'm
not naïve, and I realise that if left well alone, future
generations can carry on where we leave off. The trouble is once
active caring stops, people tend to destroy without a second
thought, put up buildings with ill-considered foundations, or
simply obliterate through ignorance.
Did you see the news article about the VR tour of Stonehenge
now available on the internet? I only caught the end of it and
was kicking myself for not seeing it all. Then I realised the
graphics looked just slightly familiar. Now near where I work
they've just opened one of these new-fangled internet-cafés where
you pays yer money and gets half an hour sitting at a PC
exploring the web-sites of the world. The news had mentioned the
internet, and I knew the Third Dimension had a presence there;
so I went along to the café to see what was what. The first place
dialled into was the Third Dimension's home page - incidentally
I didn't need to add the final "/index.html" on the address, this
only confused the browser software (Netscape). I see that it's
based at Greenwich University, and that that noble institution
takes no responsibility for what appears on its pages! A
promising start, I though! Never the less it looked like a good
advert for the Third Dimension to me, and hopefully it will pull
in some more members. I did my best to search around for various
things (bear in mind it was my first 'go' on the internet) and
was hoping to down load a few juicy worlds to explore. The café
will sell you a blank disk for the very purpose at ú1 each - they
don't let you bring your own, which is fair enough I suppose.
Anyway I didn't find any, but that is probably just me getting
confused. In a couple of weeks time I'll have another go.
(This prompted me to write the net article which has a list of
sites for you to explore...Tony)
The next 'site' I visited was Superscape's home page because
I recognised their work in the Stonehenge news item. Sure enough
there was a press release about Stonehenge, plus several other
worlds you could down-load. Now still being keen to experiment
I thought I might as well try afterall and asked the chap in
charge for one of his lovely diskettes.
Anyway, after eventually having to go to the Intel home page
(they co-sponsored the Stonehenge project) to track down the
world, I saved it out to my disk. I was about to explore further
but the people in charge informed me I had run out of time. Half-
an-hour doesn't last long on the web. I should have known! The
old "I'll just be on the computer for ten minutes, dear" is a
phrase we've all used, and know full well is going to be more
like two hours!
(It sure is!....Tony)
The Stonehenge world only just loaded into my out of date
version of the Superscape Visualiser, but still allowed me to
have a good old look round despite it being the wrong version.
This run-time module allows you to view in several resolutions
so I could use 320x200, 640x480 or a whopping 1024x768, all in
256 colours! Needless to say the thing was painfully slow at the
highest resolution; never the less the graphics are great. You'll
find a selection of screen-grabs on the enclosed disk. Sheng002
and 009 are in 640x480, the rest are in 1024x768. (Incidentally
I think that the lumps and bumps and hedgerows are actually
bitmapped textures if viewed with the correct version of the
viewer.)
I must say the quality of kit worlds and borders appearing in
the Third Dimension never ceases to amaze me, and the set of
robot brushes included last month shows what can be done with
this very powerful feature. As far as the kits are concerned I
suppose there is really no point in trying to coax the authors
into bringing out a newer version, or complaining about bugs.
What we have is what we're lumped with, and it's down to the
ingenious amongst Third Dimension readers to show what can be
done.
(Re- the Authors - Seen that, done it!, It didn't
work!...Tony)
I have to admit though, that my 'little' project has virtually
no FCL in it at all, apart from the odd video and area to area
transportations, however I can see there are a lot of
possibilities for great improvements by using it. For an example,
I'm starting on a completely new area (don't expect any instant
results yet though - it's still in the planning stage!) based in
and around a Roman bath-house.
Standing back and thinking about a project is always a good
idea - a bit like deciding on the fields and indexes required of
a database before you go ahead and start adding the data. If
you're not careful there can be some serious flaw in your
structure which is hard to correct later.
I have to think what is required of the finished bath complex
- where it is possible to explore, what I want people to see and
how I expect their surroundings to react to their presence. So
for example, I can have a hot room, rather like a sauna, with a
carefully programmed fade to give the impression of a foggy,
steam-filled room. I can have a warm room with a pool of
shimmering blue water (fade again so we can see the bottom) and
benches all around. I can have a cold room with a plunge bath of
icy water to close the pores afterwards. Outside there are to be
the furnaces and stoke holes, perhaps with the odd flickering
flame made from red/orange coloured triangles overlapping each
other and going vis-invis in an endless loop. Ther should be
smoke too, coming from chimneys - perhaps the kit 2 spheres with
a grey fade applied, rising vis-invis in a column....
Populating my world with people is the only downside to the
project - quite simply it ruins the overall effect. I did try in
the early stages (oohh, way back in 1991 I should think - well
as soon as kit 1 came out, anyway!) and had this chap coming over
to greet the new explorer at entrance one, area one. Sadly he
looked more like a stack of cardboard boxes, and despite the
useful text window he spoke through offering help, was soon axed
as he looked too much like the buildings he was standing against
(see the statue on the horse in my demo areas for the general
idea). I did try using a brush bitmap when kit 2 came out but
decided it was too tricky to get right. Like all good simulations
and VR available today, people rarely figure - except in arcade
games and the like - because although we can accept a cube is a
box-like building, it's much harder accepting a couple of boxes
as a person (forget about Rik Mayall's 'Dave the cardboard box'
for now!).
Last year (or maybe '94 - time flies doesn't it?) English
Heritage and IBM created a set of virtual Roman baths from what
I think was a French site. This was done photorealistically along
a fixed, pre-recorded viewing path. It was so realistic I began
fiddling round with conventional ray-tracers and CAD packages as
a means of recreating our ancient past. However what no one apart
from readers of the Third Dimension seems to realise, is that
none of this stuff is real-time. It might be in three or four
years time if technology goes on developing the way it has
recently, but not just now. The Kits and one or two other
packages - few and far between at an affordable level - may not
offer us the detail, but they certaily allow us freedom to roam,
to interact - and to jump into the cold-plunge of a Roman bath
and shudder with the cold! For me this ability far outstrips the
realism of other techniques. You only get a feeling of space, of
area, volume, claustrophobia, if you can move yourself and get
information from your surroundings - just like we do in the real
world.
Well, there you go Tony, a bit more waffle kit-wise. I'm
currently trying to update my CAD 2D drawing of my Lindum project
to incorporate the new information I've received. Detail is still
sparse but at least I've something more to work on now, and I'm
aiming for a second demo with a few more features than I usually
put in, as per my paragraphs above.
Best regards
Nigel.

To Mieke:-
Thanks for the information about Imagine, I was sure that the
Amiga magazines would give the programme a good coverage! You
probably know that PC Format magazine (is this available in
Holland?) has started a tutorial at last. So I'm getting tips
from there. In fact this has been the only reason for me to buy
it - at ú4.99 a throw, perhaps it would be cheaper to buy a book!
-----------------------
Dear Tony
Thanks for another great issue. I really enjoyed the Imagine tutorial
and really admire your dedication towards the 3D kits and the help
that you give.
Yours Martin Dodcross.

To Tony:
I see that you are still supporting the Atari machines, Tony.
There seems to be less disks coming out for this each month.
I hope that you will continue to support our platform.
