Detailed Description

Material properties for ray tracing.

Indexing: materials are indexed as [source * Nprims * Nbands + prim * Nbands + band] (i.e. MaterialPropertyIndexer(Nsources, Nprims, Nbands)(source, prim, band); band is the fastest-varying dimension). For camera materials: CameraMaterialIndexer(Nsources, Nprims, Nbands, Ncameras).
