John,
Thanks for pointing out the camera rotation work around. I wrote the
comparison late at night and left out many features from both programs.
I stand by my statement referring to Lightwave's displacement mapping.
To obtain anywhere near the quality of Lightwave's procedural
displacement mapping would require a morph object for every frame.
Obviously this becomes cumbersome. For the sake of discussion, I'll
use the waving flag example. To get decent motion accuracy would
take 20,000-30,000 polygons. For a five second animation you would
end up with 3,000,000 polygons in your mesh. It would be very
tedious to set up all of the morph targets as well. Plus I still
don't think you could obtain the same level of accuracy. For all
intents and purposes it is impossible. I know you can do a work
around and make it less complex but at the expense of realism. About
a year ago a major client called up needing an animation involving a
waving flag. They needed it completed in less than 24 hours. This
was a huge corporation with a massive AV department. They have more
Tellys than I can count. Their animators, who exclusively use 3DS,
were unable to complete it in however long they had to work on it. I
did the entire animation in the 24 hours. Setting up the actual flag
motion took about 2 minutes. All I had to do was click two buttons
and enter the texture size. When they reviewed it they freaked.
First of all they couldn't believe I had finished it in such a short
amount of time, but more importantly they couldn't believe the
quality. One guy thought I composited a real flag in. I didn't
actually think it was that good. If I had more time I could have done
a much better job. Using 3DS I would have had to take huge short
cuts to get it done that quick. I doubt that they would have been
impressed if I had used manta wave to create the motion. Setting up
the 360 morphs with 11 million polygons wouldn't have worked. I
think I have made my point.
BTW, what was the last version of Lightwave you used?
