The following is an informal review of SIGGRAPH '85 held in San Francisco last week. This review is by no means comprehesive. In fact, it is mostly subjective! BOOTHS ------ As measured by crowd depth, the following booths were most popular: Lucasfilm - far away the most crowded(Commodores aisle was smaller ...|:-). Demo of the Pixar. Commodore - I never did get close enough to actually see the just released AMIGA. GE - GE's 3-d version of their projection display was a real crowd pleaser. Cubicomp - featured live demos of the Picture Maker 3D system. Robert Bosch - live demo of animation system Abel Graphics - demo of animation system OUTFITS ------- No question about it, Rob Pikes black and yellow polka dot harem pants! Second place was the orange Hawaiian prints of the Symbolics people.

SIGGRAPH was interesting this year. My "fave rave" was Steve
Gabriel's paper on rotationaly invariant splines. His "physical proof"
of 720 degrees of rotation should have been videotaped. (was it?)
Here is a question; more of a homework problem: The PIXAR demo
showed a "real-time" 2-D FFT on a 128 * 128 image. It looked more like
10 transforms per second, so let's say it took 100mS to do the transform.
The CHAP (channel processor) board on the wall had 4 29116's, each with
their own 16-bit multiplier. Assuming a 100nS cycle for the 29116,
and free to guess about the PIXAR's internals, how many CHAP boards
were in the system?
ps: I don't know the answer. I really just want to hear people's
ideas on architectures for novel FFT techniques. The choice of decimating
in time or frequency is some help; but if we assume that the PIXAR has
some high speed -block- access to the image-store, that could be the clue.
One last SIGGRAPH note. Did everyone attending see the ABEKAS A62
digital disk recorder? It would seem that you "shaded cone heads" would
need something like that to deposit your pictures into. Is this going
to replace the SONY 1" still-frame widget. why/why-not?

Write-once disks video-disks provide approx. 30,000 frame/side and are virtually indestructable. Why erase when you don't have to? Simson L.

Someone suggested that write-once video disks would replace the Sony single-frame 1 inch VTR. Not yet, at least not in some applications. The Sony writes standard, broadcast-quality video onto tape. The Abekas stores frames and then plays them back in real time for recording on an ordinary VTR; I don't know if the Abekas is broadcast-quality but there certainly are framestores that are. The write-once video disks are NOT broadcast quality. Better than half-inch VTRs probably, but not good enough for commercial video production.
