Detailed Description

like ColorUniformNoise but averaging over normal distributed noise instead.

Constructor & Destructor Documentation

ColorNormalNoise ( double  tau = 0.05 )

inline

virtual ~ColorNormalNoise ( )

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 from NoiseGenerator.

virtual double generate ( )

inlinevirtual

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 double getTau ( )

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
