This web page displays the results of a number of rendering tests that compare the image quality and rendering speed of Maya’s software renderer, mental ray and Pixar’s prman.
This page demonstrates the basics of scripting using Pixar’s RenderMan scene description (rib) protocol. Writing rib files by hand focuses attention on the use of color, opacity and the fundamental concepts related to coordinate systems.
These images show the results of using the RenderMan Shading Language (RSL) to write a variety of special effects surface shaders. The notes and RSL code accompanying each image explain how each effect was achieved.
The animation and notes on this page explain how custom shaders written in the RenderMan Shading Language can be animated in either Maya or Houdini.
