houdini-pbrt-v4 for SideFX's Software Houdini is a scene exporter for the pbrt-v4 renderer. The goal is to provide complete coverage for the features avaiable within pbrt-v4 through an interface familiar with Houdini user.
Support the amazing project that is pbrt and indirectly provide more test cases for the renderer. More selfishly a common use case in a vfx production environment is to add functionality to an existing 3rd party rendering engine. Often the internals of that engine are closed making it difficult to experiment with new algorithms. With pbrt the development of new approaches can be developed within a well documented and open system. By providing an exporter for Houdini to pbrt makes translating larger production scenes into a test environment much easier.
