'Joint Photographic Experts Group' It is a method of 'lossy' image compression.

The Diamond Speedstar 24X (which supports those above modes, except has
800*600*32K) comes with a utility for windows to let you switch to pick
any graphics mode desired, and the utility will automatically restart windows
in the mode you selected.

It's very convenient.  Of course, changing modes on the fly would be better,
but I don't believe windows will allow that.

Subject: RTrace package version 8.0.0

Organization: CG & CAD - INESC Norte

There is a new version of the RTrace ray-tracing package (8.0.0) at
asterix.inescn.pt [192.35.246.17] in directory pub/RTrace

****************************************

The MAC port is being prepared to be released by Reid Judd 
(reid.judd@east.sun.com) and Greg Ferrar
(gregt@function.mps.ohio-state.edu).
A working version will be available shortly!

****************************************

Enhancements were done since version 7.3.2, mainly:

1. It has no limit on the number of objects to render (there is a
command line option to control it; scenes with up to 1000000 have been
rendered!).
The same applies to light sources and surfaces.

2. It is now possible to produce animation fly-throughs easily. The scene is
read only once and successive images are produced. There are new command
line options to specify it. The fly-throughs may be controlled by the
EYE and LOOK points, the UP vector and the APERTURE angles.
All there is to do is just create a text file with the numbers and give
it to the program...


The support programs 'nff2sff', 'nffclean' and 'nffp2pp' have been
enhanced to support unlimited number of objects, etc.


****************************************

Here goes a short description of current converters from
molecular/chemistry packages to the SCN format.

The package programs are related as below (those marked with * have been
modified)

	        irit2scn
	IRIT -------------|
                          |               NFF (nffclean*, nffp2pp*)

   CHEMICAL --------------|

****************************************

The DOS port of RTrace is in pub/RTrace/PC-386 (rtrac800.arj and
utils800.arj). See the README file.
Requires DJGPP GO32 DOS extender (included), which can be found in
directory pub/PC/djgpp (and in many sites around netland).
There are also demo scenes, manuals and all the source code...

****************************************

Please feel free to get it and use it.
Hope you like it.

Antonio Costa.

About a week ago I asked if anyone had gathered (and standardized data-types) for
performing the following :
1) Ray-object intersection
2) Object-boundingbox-creation
3) Ray-object-normal

on many different base objects (spheres, cones, patches).
It is my intention to create as large a group of these routines as possible in C
code. I was wondering about suggestions for sources of public domain code
(non-standardized of course) for these. So far I have :
1) Vort
2) Rayshade3.0 (what is this up to ?)
3) An Introduction to Ray-tracing (Glassner)
4) Radiance
5) mtv

Does anyone have any other suggestions ?

Yes, it's a FAQ, but does anyone have source code for doing Heckbert
quantization?

What I want is to convert Targa files from the POV raytracer to Gif files,
but I don't want to put a whole bitmap manipulation package on the PC, and
I don't think it's reasonable to pay 80 bucks for image alchemy just for
one type of file conversion.

I've looked at algorithm articles, but I'm sure that someone has taken the
time to do this for POV.  I'd like to be able to do 1024x768 images.  If
nobody has done this, maybe I'll have to write a special-purpose converter.

The question below is directed to the AutoCAD expert, and bear with
me if this is not exactly the right forum.

Can you define different 3D objects in AutoCAD and give them some
kind of hierachical relationship between the objects ? May be something
similar or of the same idea as PHIGS ? or do you only draw one object
at a time. What if my intention is to model the dynamics of the 4 wheels
of a vehicle, with the drawing input from a AutoCAD DXF file format. Is
there any clean way for me to input the geomatrical data of each wheel and at
the sametime note the relationship (in this case I'll only expect a
geomatric relationship) between them ? How will it look like in a DXF file ?

Thanks a bunch,

-Osbert

The fact that you are asking for a 1,2,3 point perspective indicates

you actually only need a single point perspective to accomplish

Try wuarchive.wustl.edu /mirrors/msdos/graphics/...  I believe it is there.
Any of a number of SIMTEL20 mirror sites (wuarchive and oak.oakland.edu
being the best, IMO) have it under their respective ../graphics/.. directories,
as well as SIMTEL itself, under, I think, msdos/graphics.  SIMTEL is a bitch
and a half to get around in, though; I would recommend you stick to the
mirrors.  Oakland usually has the new stuff in a few days.
	If you are psycho and want to try SIMTEL, the address is:
'wsmr-SIMTEL20.army.mil'.  On all these sites, login as 'anonymous' and send
your own system login as a password.  Once you know the system begin your
password with a dash ( '-' ) to get rid of the intro stuff.

Hi,
there is a multinorm LCD projector out from Sanyo.

It is called something like L2000 or simular.

It handles NTSC and PAL and Secam.

To display your VGA screen you can use the PC2TV adaptor from Genoa
systems, which is an internal Genlock board,

or you use our TV converter, which is a SVGAtoVideo converter box,
hooked to the VGA output connector.
It also supports the 640x480x24bit mode of the Genoa 7900 true color
card (170 US$) !!!
So you have true color on LCD projector under win3.1 or with VPIC5.0 !

Our SVGAtoVideo converter box has also Y/C and RGB outputs and is
250 US$, but in this moment has only PAL standard.
NTSC will be soon available.

Email me , when you need some more info...

Best regards Stefan Hartmann.

	Ce que j'aimerais pouvoir faire essentiellement c'est creer une image avec
un programme comme PaintBrush ou PaintShow et utiliser cette image avec la commande
_putimage en C.  Est-ce que quelqu'un peut m'expliquer brievement la facon dont les
images sont sauvegarder (formats PCX et TIF surtout) qui me permettrait de les 
utiliser.  Sinon, connaisser vous des bons ouvrages de reference sur le sujet?

Merci d'avance...

	Mike.
