**************    Call for Demos   ****************

The Museum of Science and Industry in Chicago is creating a 7000 sq.
ft.  permanent exhibit on Imaging Science which will open in the Fall
of 1993.  The museum is currently looking for working demos in the
following areas:
 
*  Virtual Reality
*  Scientific Visualization
*  Visualization of Earth Surface Data (esp. Chicago Area)
*  Physical Model Simulation
*  3D Object and Scene Rendering
*  Image Processing & Enhancement
*  Artistic Imaging
 
The museum is particularly looking for real time, interactive demos
that would appeal to a broad, non-scientific, non-technical audience.
 
The demos *must* adhere to the following requirements:
 
*  Be *FULLY* working.
*  Have complete source code available which the museum can modify.
*  Be visually exciting.
*  Demonstrate an important aspect of Imaging Science technology
    and its uses.
 
This is a great chance to put your hard work where it will be
inspirational to the next generation of thinkers, while earning well
deserved public recognition of your endeavors!

   How can I save the animated screens to a file.

2. If it is possible to do the above, is it possible to transfer

> Thought this newsgroup might be able to help me out
>

I am part of a company that is developing software for people
involved in animation, i.e., professional animators (computer based)
and amateurs.  Without saying too much, the product will be a companion 
product to products like (found on the amiga computer) dpaint (anim files)
lightwave, real3d, etc.  Simply put, the pruduct will greatly improve
the problem associated with single frame recording animation to tape.

The product that we are developing has a rough pricing of $1000 US.  Our 
preferred target market is the professional animator, however, at a $1000
it's possible that amateurs may also be interested.

What we need is information about people that we intend to market
to.  Any information would be helpful, especially references to magazines, 
and articles that can back up particular claims.

Here's a brief list of the kind of information we are looking for:
(the purpose of all this is the development of business plan)
	- How big is the market, i.e., how many people do animation?
	- How many are professional and how many amateurs?  Are there
		any other ways to seperate the different markets?
	- What platforms are people using to develop animations? 
		Unix (which hardware, I bet Sun), amiga, PC, etc.
	- What kind of budgets do professional animators have?  
	- What is the total US budget for animators?
	- What can be said of the capital acquisition for animation
		studios?  What is it like?
	- What methods of advertisment are most effective towards
		animators?
	- What magazines are read by animators?  That is where should
		magazine advertisment dollars be spent?
	- What generally could be said about animation studios?  Are
		they grey suit or blue jean type companies? 
	- What resources contains information that can answer many 
		of the above questions?  Any professional research
		firms anyone recommends?
	- How big of problem is it to single frame record animation
		to tape?
	- What file formats should the product be compartible with, in the
		amiga world the follwogin jumps to mind: anim5, iff24.

I also sell for a company out of Boulder, called Set Technology, that supplies
a 486 box, 32 MB of ram, 500 MB hard disk, both floppies, 1/4" 150 MB tape,
ethernet, graphics board (1024x768), Sony 17" monitor, SCO UNIX, X11, NFS, 
and AVS for $9,995.

>This is a 50Mhz 486, AVS4.0 with advanced memory sharing,
heirarchical module creation (modules within modules) and executable building

This is a completely integrated, tested, ready to use system.
Set is a source code licensee of the AVS software and has the only 486 port.

Under terms of their agreement with Advanced Visual Systems, Inc., they are
precluded from selling only the AVS software seperately.

The price for AVS, qty 1, to commercial users on typical WS's (SUN, HP, SGI,
IBM6000) is $6500.

Please contact me if you require more info re AVS.

Chuck's coming over in a week so I can tell you how screaming fast this
configuration is.  I asked him over the phone to load the read field, iso-
surface, color map, and render modules and rotate that little hydrogen
thing around.  Apparently AVS uses a 'bounding box' to give interactivity
to the 'virtual spaceball'.  So the cubeythingy moves in real time and
when you let the button go, the new image is rendered.  A couple seconds.

Upshot? p5 upgrade will require a motherboard swap (although most
chips and controllers can be reused) and should come 'in a year'.

Competition? Iris Indigo is reasonable but only for 8bit graphics.
24 bit will cost you $25,000+ (correct me if I'm wrong).

Output? laser disk is best for reasons of random access, single frame
viewing, cost, archiving, reliability, space, and ease of use.

I suppose there should be some duplication in the function of all the
IBM Explorer, IRIS Explorer, and AVS modules.  Count on AVS for having
more because it's been around longer.  Khoros is 'being ported to AVS'
whatever that means.

Have you heard of GRASS(?) This thing showed up which was built by
the Army and can draw graphs.  Looks fairly extensive and has
a user community of GIS folks.  Anybody use this?

Visualization '92: 
		   Oct 18 through Oct 23 1992, Boston, Mass.

The Visualization '92 conference and the 1992 
Boston Workshop on Volume Visualization are seeking student volunteers. 
Volunteers will work  twenty hours or less in exchange for
complete free registration in the conference.  As the two
conferences are being held at the same location on
successive dates, the same students may volunteer  for both
conferences.  Come learn about the state of the art in 
volume visualization and the use of computer graphics to
study complex scientific phenomena.  

Student volunteers will be responsible for their own
transportation and lodging for the conferences.  To assist
in costs, limited shared rooms will be made available on a
first-come first-serve basis.  All students who are enrolled
full time in the fall 1992 are eligible.

(I tried this on Comp.sys.sgi a couple of weeks ago, but nobody
responded....)

(NOTE: forgive the repetitive use of the word "clever" in
the following post.)

Hello, everybody!

I really hope this doesn't start a big "when are we gonna
have Phong shading in hardware" thread.  That's not what I'm
after. :^)  (Anybody besides me remember that guy at the SGI
user's group meeting back at SIGGRAPH '87 or '88 that stood up
and demanded Phong shading?)

The best analog for what I'm after is a technique similar in
cleverness to the Stencil Shadow's algorithm that was published
a couple of _Iris Universes_ ago.

What I want to know is if anybody's figured out some clever
way of simulating bump maps on a VGX?  I would assume that
the process would involve rendering your object unshaded using a
texture map to represent a change in normal direction.  Somehow
you'd get approximate polygon slope information from either taking the
derivative of the Z-buffer or using a second pass where you render
your object using color to represent normal information.  The last
step would be a pixel-by-pixel computation of some sort, possibly
using the stencil bitplanes in some clever way.

Remember, I'm not looking for displacement maps or true bump maps.
I'm looking for SYNTHETIC bump maps, where the majority of the
work is done in hardware.  I'm not looking for a real-time interactive
technique, and I don't care if it looks ugly on the screen while it's
doing it.  I want it for a frame-at-a-time animation technique.  Images
would be video resolution.

Has anybody done this?  Does what I'm suggesting make sense?  Should
I just give up the idea of having bump-mapped objects in my animations?
Say it ain't so!

Thanks a million flat shaded polygons per second!

Garnted, alpha shapes are more complex than the convex hull, but
that's exactly the point.  The convex hull is simple, true, but it has
one disadvantage, namely that it's convex. :) Alpha shapes can be
non-convex, or even disconnected... and thus (have the potential to)
capture "shape" far better.  Take for example a point set that
resembles a torus, ie, a donut.  The convex hull of this set won't
show most of the torus' features, esp, not the tunnel, ie, the donuts
hole.  Alpha shapes do...  Or for example, consider a point set where
you have several clusters easily visible to the human eye.  The convex
hull would just make one big blob out of it.  Alpha shapes can be
usesed to seperate the clusters.

For a more formal discription of the concept "alpha shapes" I would
suggest you get the techreport (from the department or from me):

        Edelsbrunner, Mucke.  Three-dimensional alpha shapes.
        Technical report UIUCDCS-R-92-1734.  Dept of Computer
        Science, UIUC.  1304 W Springfield, Urbana, IL 61801.
        March 1992.
        
For a informal discription it's best to ftp Alvis from
ftp.ncsa.uiuc.edu and play around with it.  That's exactly why we
built the tool!  We think alpha shapes can have an enormous potetial
for scientific computing.  Many people work with three-dimensional
data, and would need some geometric structure in it.  Alpha shapes can
do that.  There is still a long way to real-life applications, but the
main goal of Alvis was/is to make the new concept known to the
scientific community.  You know, a paper doesn't impress anybody, but
if you have a code and can show things to people, that get's attention.
