PSFPTVertexProcessor Struct Reference

Detailed description

A simple implementation of the TPTVertexProcessor policy interface required by all the PTLibCore functions. This class is responsible of processing each vertex generated by the path tracer, including:

• the computation of NEE weights
• the computation of scattering weights
• the accumulation of emissive surface hits
• the accumulation of NEE samples
