Static Public Member Functions
static plSimdVec4u	UInt (const plSimdVec4i &vPosition, const plSimdVec4u &vSeed=plSimdVec4u::MakeZero())
	Returns 4 random uint32 values at position, ie. ranging from 0 to (2 ^ 32) - 1.
static plSimdVec4f	FloatZeroToOne (const plSimdVec4i &vPosition, const plSimdVec4u &vSeed=plSimdVec4u::MakeZero())
	Returns 4 random float values in range [0.0 ; 1.0], ie. including zero and one.
static plSimdVec4f	FloatMinMax (const plSimdVec4i &vPosition, const plSimdVec4f &vMinValue, const plSimdVec4f &vMaxValue, const plSimdVec4u &vSeed=plSimdVec4u::MakeZero())
	Returns 4 random float values in range [fMinValue ; fMaxValue].

Detailed Description

Noise based random number generator that generates 4 pseudo random values at once.

Does not keep any internal state but relies on the user to provide different positions for each call. The seed parameter can be used to further alter the noise function.
