Aqsis Renderer README

Aqsis is a high quality, photorealistic, 3D rendering solution. It complies with the RenderMan(R) interface standard defined by Pixar.

The RenderMan(R) standard has been used in film and television visual effects since it's introduction in 1989. Pixar has used their own implementation for all of their award winning CG features, and provided their implementation for use in the visual effects of most major blockbuster films over the last 2 decades. The Aqsis project offers a way for individuals and organisations alike to gain experience with the RenderMan(R) interface without the cost of commercial software licenses.

Aqsis comprises a command line rendering tool, a tool for compiling shaders in the RSL language, a tool for preparing textures for optimal use, and various developer libraries to enable integration with third party tools.
