Jerry,
I'm a Mac user who is interested in the Amiga but has never tried Lightwave. I
have also never used the SGI programs…. So what can I contribute to this
conversation? Hmmmm…
Well last summer a dealer here in NY hosted a series of in depth
demos by Alias, SoftImage, and Waverfront (at the time I was
considering switching to SGI). I went to them all and was blown away
by their realtime capabilities. For instance in the Alias
PowerAnimator demo they had a smooth rendered sphere on the screen,
and could draw a spline on it's surface and then cut out a section
all in realtime. They could also apply a texture and once again move
it around in realtime until it was positioned correctly.
PowerAnimator has some nice atmospheric effects also. You can shine
rays of light through fog without having to cheat using cones etc.
You can simulate gravity, magnetism, "blow" things around with wind
etc. One nice modelling feature was the ability to take an object (a
sphere for instance) and push & pull parts of it (like clay) into
whatever weird shape you want…all in realtime. They created a
detailed face very quickly this way. They also created a killer whale
the same way; defined an undulating path (sine wave shaped) for it
with a spline; then animated it along the path…the cool thing was
that when it came to peaks & dips in the path, it would actually flex
the way a real killer whale would…in realtime (wireframe)! There
are also nice inverse kinematics features, animatible procedural
textures, and a nice randomize feature in the timeline that would be
great for doing things like flocks of birds, bubbles etc.
This was all just in PowerAnimator. Wavefront had realtime
particle effects, SoftImage had great animation features like being
able to modulate objects movement from a microphone hooked up to the
computer etc etc etc. Alas I will stick with my Mac for the time
being. Even though these packages are getting more reasonable, the
hardwear is still up there (a fully loaded Indy packs a lot of bang
for the buck, but it's still very costly and SGI also makes you pay a
high yearly fee for technical support).
Long winded enough??????

P.S. What is a Raptor????!!! Is this a code word for the Screamer,
perhaps a baby Screamer?? I'm confused!
