I also found this interesting bit (more on this page):
"Yet the biggest new feature by far in CAD-3D 2.0 was the ability to render to the new "delta-compressed" animation format developed by Mark Kimball. The basic idea was to start with a picture, and then for each subsequent "movie frame" store only the parts that change, rather than storing each frame as an entire picture, thus wasting data. Mark Kimball implemented this process as an Atari ST desk accessory called Cyber Smash."
This is exactly what Magic Lantern (ver. 2.0), written by Michael Todorovic's company, Terra Nova Development, did for 24-bit graphic cards for the Amiga. I've got it & it's pretty impressive.
