I have heard that the U.S. government want to develop the use
of PHIGS and GKS. That is why SGI is searching a PHIGS to put

Is it true ?

Okay, since you brought it up :^)....

Do you think SGI has any plans for incorporating MPEG or JPEG
compression/decompression chips into their hardware architectures?

I imagine that you'd need a set of JPEG library routines like

jpg_compress(FILE *jpg_file,unsigned long *parray)

or 

jpg_memory_uncompress(unsigned char *jpg_array, unsigned long *parray)

or

jpg_mem_lrectwrite(unsigned char *jpg_array, left,right,bottom,top)

This would be _really_ cool and, IMHO, very do-able.  It seems like
the major stumbling block would be SGI's willingness to commit to
the JPEG or MPEG standards.

Let's say I rendered a minute or so of animation, and since I didn't

and lay the images to tape, will there be artifacts introduced by the
JPEG compression? Any pixel flickering or shading strangeness going

Date: 14 Dec 92 17:23:06 +1300
Organization: University of Waikato, Hamilton, New Zealand

On the QuickTime 1.5 developer CD, there's a music video called "Theology".
It's got an instrumental, Pink-Floydish number for the sound track, but the
video is spectacular--it's all synthetically rendered. It starts out as an
egg-like object on a mound in a landscape, and then evolves into a
Stonehenge-type monument, then the interior of a cathedral-like building, and
more, with shapes morphing into one another. The movie file is 15MB in size,
and it runs for 3 minutes and 4 seconds.

The only pity is, it's done at 160*120 resolution. I suppose they figured
the 15 frames per second wouldn't tax low-end machines at this size (it even
plays smoothly directly off the CD), but it would have been nice to have a
larger version available, for those who could play it.

The thing I'm wondering about is, there are no credits for that movie that I
can find, either in the movie's user data (which I checked with Dumpster), or
anywhere else on the CD.

Does this video sound familiar to anyone else? I'd be interested to know who
did it.

Ahem;
	IMHO, they have been taking a wait-and-see attitude after what happenend
to NeXT with C-Cube JPEG compressor.  NeXT had planned to offer JPEG in
hardware on this board, but the C-Cube CL550 codec failed to perform as 
advertised. Now that decent silicon is available, I'd expect SGI is working
on it...of course, the NeXT thing may have nothing to do with it, but as
these things go it's a pretty small industry.

Hi Everyone. I hope this is the right place to ask this question
It is related to an artical that I read in a computer magazine
refering to doing animations of starships in flight.

Now what I want to know is when you see a shot of a spaceship
say on StarWars how do they compose the shot (ie how do they do
it?) what is the process for doing this, I will tell you what I
know and I hope that someone can help or point me in the right
direction without flaming me. After all it is Christmas.

From what I know they first film the stars ie a background plate
then they film the model against a blue screen. Why?

Next they do the same to get just lights and engine outlets?
Why not do this in the same shot as the model or are the lights
rotoscoped onto the film later?

Now and this is where I get really lost they create a black
negative of the ship to use as a mask when exposing the file
But why. Is the reason for this because the stars and the ship
can't be filmed together. My final question is do you have to
go through any of this when creating a computer animation of
say a starship, or is it just a simple case of pasting a ship
onto a backdrop of stars.

Thanks for Any help Gary.

   The video is the newest from Todd Rundgren and his Nutopia company.
This premiered at a party at this last SIGGRAPH.

    Perhaps you had seen Todds previous video, "Change Myself"? That one
and this one were produced with the Lightwave portion of Newtek's
Video Toaster. For the last two people who are unfamiliar with this
product, it's a board that plugs into a Commodore Amiga 2000 and
provides 2 framebuffers, a 4-input switcher and SEG/DVE, paint, color
processing and a state-of-the-art 3D modeling, animation and rendering
program for $2400 US.

    Todd is a big Mac fan (he developed Flowphaser) but Lightwave was
more powerful than anything available on the Mac. "Change Myself" was
one of a handful of fully computer animated music videos, and the first
to be created entirely by the musician. 

    "Theology" is intended to be a final "proof of concept" of using
networked Amigas and Macs to create commercial animation. Photoshop
(and I believe Fractal Design Painter) was used to create the amazing
texture maps, which were then netted to the Amigas into an advanced
version of Lightwave for animation and rendering. 

    One of the heartbreaks of this last SIGGRAPH was "Theology"s absence
from the film and video show, and the final tape was not ready in time
for consideration. IMHO, the selection commitee had an anti-Amiga bias.

Well, to fit this topic into this newsgroup, here is a peace token for the
net police : "Matts are also used in computer animation, you just don't
have the same problems or have to worry as much."  Now on to some  discussion
of why people use bluescreen techniques.

First, the background is filmed separately.  Why?  Because it is much
harder to try to have the background really in back of the model so you
can film them together.  Also, this technique allows you to play with scale.
That is, your background is a house, and you want a giant spaceship landing
on it.  You don't want to have to build a giant spaceship, so you film the
house first, then you get your model of the shapship out and film it much
closer to the camera.  Then you put the shots together.

Second, why a second "beauty pass" for lights?  Well, this is probably
because you have to light the model in the model filming stage.  The engine
lights they use are quartz halogen with some fumes blowing over them to create
the smoke or haze effect.  Now, if you expose film for the lighted model, any
engine you had on at the time would be drowned out by the  bright lights you
are using to light the model.  Either that, or your engine lights are so
bright that they will be overexposed if you expose for the ship.  Remember,
film has a narrow exposure lattitude.  So, you film the ship in one shot
with its proper lighting and exposure, then you turn out the lights and
film the engines and running lights with thier proper exposure.  Now you
put all of them together.

Now, the matte.  Mattes are used in film and computer graphics.  In graphics,
they are usually called masks.  The purpose of a mask is to "punch a hole"
into your background that is exactly the shape of your shaceship or whatever.
In film, this is because when you overlay pieces of film, stars would show
up through your spaceship without first having a black matte to block them.
In computer graphics, this is so you can have an object move over a complex
background while having the background "show through" all the right places.
Remember that computer shapes are stored as rectangles.  If you drew the shape
without a mask, you would see this rectangular boundary.  By using a mask
first to punch a whole, you can use simple AND/OR instructions to draw your
shape into the hole.  A mask tells the computer what parts or boundaries of
the rectangular shape are to be background, and which are to be the shape.

I'll appriciate if you e-mail the information directly to me.
