- It is pretty amazing, and as they say "It just works"
-
- Let me start being saying that I am doing most of the RenderMan work on
- a Cube. Performance for interactive RenderMan is quite reasonable. It
- will skip complicated operations when it starts to fall behind. For
- instance, if I am rotating around a complicated object, it might just
- show me the start and the stop point of my rotation. Interactive
- RenderMan can be controlled, via some of its primitives, to improve or
- lessen the quality of the rendering, which has a inversely corresponding
- effect on the speed.
-
- Photorealistic RenderMan is a different story. It basically acts like a
- printer. You can configure your NeXT (or better yet, all the NeXTs on
- your network) to act as renderers. Then you just send your file to the
- machine and wait for the output. The speed of the rendering depends
- heavily on the quality of your image, the complexity of your scene, and
- the complexity of your shaders. As a rough benchmark, I can generate an
- image of the teapot with one light with most shaders in a 72x72 (1 inch
- x 1 inch) window in 10-20 seconds.
-
- The point is that you use interactive RenderMan to do your on screen, or
- rough draft work, and then let photorealistic renderman crank on the
- final version of the hours in may take.
