Detailed Description

Interface and basic class for noise generator.

It is suitable for single noise channels but also multidimensional noise.

Member Function Documentation

virtual void add	(	double *	value,
		double	p1,
		double	p2
	)			[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())
	p1	first parameter for random number distribution
	p2	second parameter for random number distribution

Reimplemented in ColorUniformNoise, ColorNormalNoise, and SineWhiteNoise.

virtual double generate	(	double	min,
		double	max
	)			[pure 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

Implemented in WhiteUniformNoise, WhiteNormalNoise, ColorUniformNoise, ColorNormalNoise, and SineWhiteNoise.

virtual void init

(

unsigned int

dimension

)

[inline, virtual]

initialization with the the given dimension for multidimensional noise
