Summary: Comp.Graphics education at Princeton (from an undergrad)
Originator: news@nimaster
Organization: Princeton University
Date: Fri, 8 Jan 1993 19:06:31 GMT


The Visual Arts department and Computer Science departments here offer courses
using SGI workstations, and have a few high-end Macs, as well. There are
currently over 150 Iris workstations in use on campus, over 60 or 70 of which
are general access (any enrolled student).  Last I heard, Princeton was the
second largest SGI location.  First being SGI itself. :)

You will, however, have to deal with the rest of the departments' requirements
for a more balanced education.  I only started studying graphics in Feb. '91,
but I still have managed to take 3 grad courses on graphics, and particularly
on animation, plus two undergrad courses in that time.  Job opportunities are
good, too -- of the 44 interns at SGI this summer, four were from Princeton,
plus one more who began full-time employment there.

The graphics part of the CS dept. has been expanding rapidly ever since Pat
Hanrahan (aka "the Graphics God") came here from Pixar in '90.  There are
several other "godly" graphics people who followed him here or were encouraged
by him to come (like Craig Kolb (RayShade), Michael Cohen (Radiosity), Don
Mitchell (just about everything), and others).  The department has several
Indigos (R3k/R4k) Elans, Crimson RE (2RM), Crimson Elan, 220/VGX, among
others.  The public clusters consist of PI/35 Magnums (DSP), 210/VGXs,
220/VGX, PI/25s, and a central compute server which is a hybrid 4D/480
(2x33MHz R3k, 6x50/100MHz R4k).  Various NeXTs and Suns are available, as
well.

VisArts and CS have had visiting professors, as well.  The ones I have worked
with are Vibeke Sorensen (CalArts) and Copper Giloth (UMass@Amherst?).

Hope this helps!

This type of data is pretty readily available, especially on the NASA

terrain data - I strongly suggest you use some of the USGS DEM data
that is available on spectrum.xerox.com.  There is a learning curve
concerning the file format - but I'd be happy to Email you source
code for some programs which will take USGS DEMs and make them

     First, did I pluralize 'index of refraction' correctly?

     Second, and the main reason that I posted, I'd like the indexes of
refraction (and 24-bit color, reflectance, and transparency) of transparent
substances.  I would like as much information as possible on the indexes of
refraction, but just the average would be fine.  I would prefer electronic
copies, ftp files, and paper references in that order.

     If I get enough responses, I will post a followup message with the
information and/or ftp location(s) where to find the information.

     Since I read mail via NNTP, the reply address in the header is incorrect.
Send any responses to the e-mail address in the signature.

Hi Folks,

I'm posting this for a gentleman named Mr. Yossi Glass who
works for DEC in Israel.  Yossi doesn't have access to the 
newsgroups directly, so I am taking care of this for him.
Please send any responses to me via email, and I will
forward them on to Yossi.  Thank you and Happy New Year !

----------------------------------------------------------------
I am looking for a way to create 3D models, and manipulate them 
from an application.  A possible way to do that would be to use 
the "create geom" module of AVS, write the data, and then read
it from an application and render it using PHIGS. 

Has anyone done something like this?  Or can I get the source 
code of a geometry viewer module of AVS that does this (using
PHIGS)."
 
Thanks,

- Yossi Glass

From the AVS User's Guide, pg 3-18, in "Starting AVS":

-parallel n

Sets the maximum nunmber of module processes that will attempt to execute in
parallel at any one time.  The default is 1 (no parallelization).  You should
set this figure intelligently for the system(s) you are running on.  If two
processors are available (a two-processor system, or a local and a remote
system) then this figure can reasonably be set to 2.

...

Modules must be in separate processes to execute in parallel.  Most modules
supplied with AVS are combined into a single executable that runs as a single
process ["mongo"?].  Thus, they will not run in parallel unless they are
divided into separate processes.  This may be done wholesale with the -separate
option (which may greatly increase memory utilization), or precisely using the
Network Editor's module group editing facility.

	I'm trying to build ghostscript on VMS.

	only the X windows driver.  When I try to build for supporting

	Has anyone gone through this and gotten the VMS version to
	work with output to a GIF (or PBM or other) file?

	I could really use any input anyone has on this or if anyone
