Lightscape Viewset (light-08)

The light-08 viewset was created from traces of the graphics workload generated by the Lightscape Visualization System. Lightscape combines proprietary radiosity algorithms with a physically based lighting interface.

The most significant feature of Lightscape is its ability to accurately simulate global illumination effects by precalculating the diffuse energy distribution in an environment and storing the lighting distribution as part of the 3D model. The resulting lighting "mesh" can then be rapidly displayed.

There are five tests specified by the viewset that represent the most common operations performed by the Lightscape Visualization System:
