Member Function Documentation

virtual sheep::Real toxic::IEDF::Evaluate (  const Context &  context, const sheep::Vector3 &  direction )  const [pure virtual]

Evaluates the function. The emission direction is expressed in local space. Implemented in toxic::LambertianEDF.

sheep::Real toxic::IEDF::GetEmittedRadiance (  const Context &  context, const sheep::Vector3 &  normal, const sheep::Vector3 &  direction )  const [inline]

Utility function. Parameters: normal  On the light source, expressed in world space or object space. direction  Away from the light source, expressed in same space as the normal. Definition at line 88 of file iedf.h. Referenced by toxic::Sphere::ComputeIrradiance(), and toxic::IAreaLight::ComputeIrradiance().

virtual void toxic::IEDF::Sample (  const Context &  context, sheep::Vector3 *  direction, sheep::Real *  prob )  const [pure virtual]

Samples the function in order to obtain an emission direction. The probability with which the direction has been chosen is also computed. The emission direction is expressed in local space. Implemented in toxic::LambertianEDF. Referenced by toxic::IAreaLight::GeneratePhotonRay().
