Member Function Documentation

Eval()

virtual Color PGENLib.BRDF.Eval ( Normal  normal, Vec  inDir, Vec  outDir, Vec2d  uv  )

virtual

Reimplemented in PGENLib.SpecularBRDF.

ScatterRay()

virtual Ray PGENLib.BRDF.ScatterRay ( PCG  pcg, Vec  incomingDir, Point  interactionPoint, Normal  normal, int  depth  )

virtual

Abstract method to be implemented in the BRDF derived classes.

Parameters
