Has anyone out there had any experience getting explorer 
running on a SUN? I've heard of a few ways to do this..
apparently NAG in the u.k has, or is about to have, a port 
that uses the XGL stuff on the Sparcs. Another option is
to get Nths Protable GL library for which Sparc compatible
explorer executables maybe obtained. The third is to get
similiar product from Dupont. I'd be interested in hearing 
about anyones experience good or bad with these or any other
options.

You might want to connect the output of your dscribe module to
PrintLat module.  This should help you to verify whether the data
is read in correctly.  Send me mail if you still have problem on

It isn't alpha planes that you need, it's blend hardware.  You can write
a little program to find out if you have the proper hardware with a call
to getgdesc().  To the best of my knowledge, it is not available on PIs.

Have you ever seen Lightwave 3D for the Amiga?  The Scene Layout screen
can be set with buttons for visability of items other than the object
such as camera, lights, grid, overlay (NTSC,Letterbox).  When you make
the lights visible, you see a full 3D lighting instrument with barnd
doors.  You can then click on the light button so that you have control
of the light.  You can then click up/down through the lighting sources
and pick the light you want.  From there you can just move the mouse to
rotate or move the light where you want it.  You can see this in a
perspective view and any of the other views as well, you can do it in
the camera view if you want.

It's very elegant.  The only items I can think of that would make it
even better is something to show the actual cone angle, falloff and edge
angle.  If that was in there, you would be able to see exactly where
your light is shining and how large an area it is actually going to
affect.

Mark,

To answer your question about Touch Screens, I know that IBM
makes what it calls the TouchSelect that fits over your 
current monitor.  I haven't seen it in action, so I can't
really recommend it, but if you'd like to get a price,
you should be able to get it by calling 1-800-228-ULTI.

I have just one little thing to add:  I have noticed that in some cases if
I start with a GIF that isn't very good, eg too grainy or off-color dots
showing up, I can run it through a JPEG compressor using 256 color quant.
and get an IMPROVED picture!  In particular it seems to be able to smooth

I think you misunderstood what I have said.

TL> Or are you really arguing that the variable compression

In that point, I simply argued that it HAS been misused and will continue to
be. I also argued that one way GIFLITE is superior to JPEG in that is does not
require a great deal of time to convert it into a format that can be easily
displayed.

You should see the performance monitor on the Sequent when I peg all 24
CPU's at 100% when I go converting JPG's to GIF. Or the extensive time it
takes on my PC, for that matter.

Summary: Comp.Graphics education at Princeton (from an undergrad)
Originator: news@nimaster
Organization: Princeton University
Date: Fri, 8 Jan 1993 19:00:33 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!

For an NTSC television, the standard display for Photo CD is 768x480, which
takes 1.10 megabytes if stored at 3 bytes per pixel.  (768x512x3 for PAL is
1.18 megabytes.) The low-res picture is 384x240, the "4x" picture is
1536x960, and the "16x" picture is 3072x1920.  The 5th image is a
"thumbnail" sized picture that is used to build the hardcopy index, and it
is 100x100 (or maybe 192x192, I forget which).  Total size for all 5 images
is 8 or 9 megabytes, which is Kodak's software compresses to about 4.5
megabytes per picture.

A print created from the "16x" image is supposed to be indistinguishable
from a print created from the negative at a "1-hour" photo shop.  It is said
that at the highest resolution, the grain in the film shows up before you
can see any of the artifacts of the compression algorithm.  If this is so,
than Kodak has a lossless compression for their application.

As the graphics coordinator of the Pittsburgh Supercomputing Center I can
add our ten cents worth. Many people seem to think that writing a useful 
utility is the tricky part. This is just not true. Almost by definition
the effort
involved in any successfull system will be dominated by support, and efforts to
reduce the support requirements of a freely available system are the most 
important part of its development. 

Once you decide to try for some reasonable amount of bug fixing the most
difficult scenario to deal with is the unauthorized user who makes changes to
the source code which (perhaps unkown to him) introduces new bugs. Trying
to deal with these, knowingly or unknowingly, is a frustrating experience 
guarranteed to pursuade most people never to release anything on the net
ever again. SDSC deals with this, perfectly reasonably, by not releasing
source.
This is cannot be all peaches and cream for them however, because it means 
they must maintain a very large number of binaries and the
machines/environments
to produce them.

In our case the PSC has been distributing several packages for over five years
now, our biggest "seller" being the CGM interpreter GPLOT, via anonymous FTP
(don't send me mail, it's on ftp.psc.edu). We worried about this problem
from the
start and decided to approach it by making the source freely available but
copyrighting it to explicitly prevent the redistribution of changed
sources/binaries.
And yes, we still have had people do this, and I have sent them nasty messages
telling them to stop. We also provide as many binaries as possible.

Other centers have other approaches; the software tools group at NCSA
explicitly
places their code in the public domain (please correct me if anyone wants to),
and it is still not clear to me whether there even is a "best" approach.
In defense
of SDSC, we have noticed a clear trend towards more of our users taking
binaries
directly rather than wishing to deal with the sources and I expect this
trend to
continue as compilers, etc., become unbundled. However, I can believe that
the availability of source gives even these users a warm fuzzy feeling, simliar
to a decent warranty on a piece of electronics.

One thing that is definitely true, if you worry too much about 100% of users
being able deal with your source, you are locked into arcane and unproductive
programming practices and out of advances such as ANSI C and C++, let alone
more aggressive approaches such as SmallTalk and Common LISP.
