Detailed Description

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

LightingContext::LightingContext (  I3DExRaytracer *  raytracer, const IllumSettings &  illum, const RendEnv &  rendEnv, const RTLevelInfo &  level )  [inline]

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

const TMCColorRGBA& LightingContext::GetAmbientLight (   )  const [inline]

Returns the intensity of the ambient light in the scene
