procedure ApplyFog(var Color: TVector3; const Position, VertexPos: TVector3; const AFogType: TFogTypeOrNone); |
Apply fog to the color of the vertex.
This can be used by software renderers (ray-tracers etc.) to calculate pixel color following VRML/X3D specifications. After all the lighting is summed up (see TX3DGraphTraverseState.Emission and TLightInstance.Contribution), process color by this method to apply fog.
Does nothing if AFogType = ftNone. In this special case, it's also allowed to call this on Nil instance.
