RenderMan

From Wikipedia, the free encyclopedia

The name RenderMan can cause confusion because it has been used to refer to different things developed by Pixar:

  • RenderMan Interface Specification (RISpec), Pixar's technical specification for a standard communications protocol (or interface) between 3D computer graphics programs and rendering programs
  • RenderMan Shading Language
  • PhotoRealistic RenderMan (PRMan), a RenderMan Interface Specification-compliant rendering software system developed by Pixar based on their own interface specification
  • RenderMan, also commonly used to refer to other renderers because of their compliance with the RenderMan standard
