Pixie – RenderMan renderer for generating photorealistic images

Last Updated on July 12, 2021

Pixie is a free, photorealistic raytracing renderer for generating photorealistic images.

The software is RenderMan-compliant (it reads conformant RIB, and supports full SL shading language shaders) and is based on the Reyes rendering architecture, but also support raytracing for hidden surface determination.

Pixie is not a modeler or an animation system. It therefore does not have any graphical user interface.

The scenes you want to render are described in a text file in a language very similar to Pixar’s RenderMan. Pixie also comes as a C/C++ library which you can link against your application.

Features include:

• Supports all RenderMan 3.2 primitives.
• Quadrics: Sphere, Disk, Cone, Paraboloid, Hyperboloid, Cylinder, Toroid.
• Parametrics: Bilinear/Bicubic patches, NURBS.
• Subdivision Surfaces including crease/hole/interpolateboundary tags.
• Points.
• Curves.
• Convex / Concave polygons with or without holes and their meshes.
• Object instancing / delayed primitives.
• Displacements.
• Raytracing.
• Reyes style rendering.
• Fast multi-threaded execution.
• Possibility to distribute the rendering process to several machines.
• Motion blur and depth of field.
• Programmable shading (using RenderMan Shading Language) including full displacement support.
• Scalable, multi-resolution raytracing using ray differentials.
• Global illumination.
• Photon mapping.
• Irradiance caching.
• Support for conditional RIB.
• Point cloud baking and 3D textures.
• Point Based occlusion and color bleeding.
