Cyber Studio CAD-3D is a 3D-modeling and animation package developed by Tom Hudson for the Atari ST computer platform and published by Antic.
The application was a basic polygonal 3D modeling and rendering program. An operator could assemble a scene out of geometric primitives or custom extruded or lathed objects. Various view ports were available to adjust lighting and camera positioning. The limited rendering functionality allowed for flat shading in 16 shades. Rendered images could be exported in Degas Elite or NeoChrome format.
By making changes between rendering separate cels CAD-3D could be used for simple animations. Without its scripting extension Cyber Control changes had to be made by hand.
As of 1987 the software was packaged together with Cybermate, a Forth-based authoring language created by Mark Kimball. This was supposed to be used to edit, sequence and present the animation files along with sound. The scripts allowed an operator to control when and how fast a video or audio segment played, and whether it should do looping.
In many ways Cyber Studio CAD-3D can be considered an early precursor to 3D Studio Max.
