Member Function Documentation

distribConcentric()

void SLRaySamples2D::distribConcentric ( SLbool  evenlyDistributed )

private

Makes concentric 2D-samples points within a circle of certain radius. With the parameter evenlyDistributed=false will the samplepoints be denser towards the center.

mapSquareToDisc()

SLVec2f SLRaySamples2D::mapSquareToDisc ( SLfloat  x, SLfloat  y  )

private

Concentric mapping of a x,y-position Code taken from Peter Shirley out of "Realistic Ray Tracing"

point() [1/2]

SLVec2f SLRaySamples2D::point ( SLuint  x, SLuint  y  )

inline

point() [2/2]

void SLRaySamples2D::point ( SLuint  x, SLuint  y, SLVec2f  point  )

inline

samples() [2/2]

void SLRaySamples2D::samples	(	SLuint	x,
