Member Function Documentation

DBL PerlinNoiseCommon::eval01 (  const Vector3 &  p  )  const [inline, virtual]

Noise in the range [0,1] Implements Noise< Vector3, DBL >.

DBL PerlinNoiseCommon::evalN (  const Vector3 &  p  )  const [inline, virtual]

Standard normal distributed noise Implements Noise< Vector3, DBL >.

DBL PerlinNoiseCommon::evaluate (  const Vector3 &  point  )  const [protected]

Is approximatly normal distributed with mean 0 and standard deviation STDDEV (this value is measured empirically and not analytically)
