PearRay is an experimental ray tracing application framework to create photorealistic or artistic single images or animation sequences. It’s in active development, but still misses some of the ‘required’ features to be fully production ready.

Based on DataLisp, BoostOpenImageIO and the Qt library it features a render viewer with an internal spectrum viewer and project settings.

A official Blender integration plugin is available here.

It’s in active development. The source code is available on GitHub.


Current features include:

  • Depth of Field
  • Spectral rendering
  • Multiple Importance Sampling
  • Texture Mapping
  • Bidirect Raytracing
  • Progressive Photon Mapping
  • Environment Mapping
  • Many Materials

Planned features:

  • OSL (Open Shading Language)
  • VCM (Vertex Connecting and Merging)
  • Displacement Mapping
  • Motion Blur
  • Animation
