Detailed Description

Info about the point being shaded and the lighting of the scene. Used for shaders that implement their own lighting.

Member Function Documentation

void LightingContext::CalcReflectDir ( const TVector3 & rayDir,

const TVector3 & normal

) const [inline]

Computes the direction in which a ray reflects on a surface. The result is stored in fReflectDir

Parameters:

rayDir is the direction of the incomming ray

normal is the normal at the intersection point between ray and surface
