Member Function Documentation

virtual void add	(	double *	value,
		double	noiseStrength
	)			[inline, virtual]

adds multidimensional noise to the value field.

Generic implementation calls generate for each channel. Overload this if you need different behavior.

Parameters:

value

field where noise is added. Must have length dimension (init())

Reimplemented from NoiseGenerator.

virtual double generate

(

)

[inline, virtual]

generate somehow distributed random number parameterized with min and max.

valid only for ONE random number, use add() for adding this kind of noise to several channels

Reimplemented from WhiteNormalNoise.

virtual void init	(	unsigned int	dimension,
		RandGen *	randGen = 0
	)			[inline, virtual]

initialization with the the given dimension for multidimensional noise

Parameters:

	dimension	dimensionality of vectors to be used by add
	randGen	pointer to a random generator. If zero a new one generated internally
