Detailed Description

Interface and basic class for noise generator.

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

Constructor & Destructor Documentation

NoiseGenerator ( )

inline

virtual ~NoiseGenerator ( )

inlinevirtual

Member Function Documentation

virtual void add ( double *  value, double  noiseStrength  )

inlinevirtual

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 in SineWhiteNoise, ColorNormalNoise, and ColorUniformNoise.

virtual double generate ( )

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 SineWhiteNoise, ColorNormalNoise, ColorUniformNoise, WhiteNormalNoise, WhiteUniformNoise, and NoNoise.

virtual unsigned int getDimension ( ) const

inlinevirtual

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

inlinevirtual

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
