Member Function Documentation

void BPTPathVertex::DebugPrint ( ) const

Debug print. Prints the summary of the path vertex.

bool BPTPathVertex::Degenerated ( ) const

Check if sampled BSDF component type is directionally degenerated. e.g. specular BSDFs or directional light

Return values

true	The BSDF is directionally degenerated.
false	The BSDF is not directionally degenerated.
