sheep::Point3 sheep::CosineHemisphereSampling (  sheep::Real  xi1,
sheep::Real  xi2
)  [inline]
 

Returns a point chosen with a cosine-weighted distribution on the surface of the unit hemisphere (see above for definition). The vector from the origin to the returned point is unit-length. Note: when doing stratified sampling, there should be 4 times more samples for xi2 than for xi1, since xi2 is used to compute the Phi angle.

Todo:
Turn the multiplication into an addition.
