Detailed Description

like ColorUniformNoise but averaging over normal distributed noise instead.


Constructor & Destructor Documentation

ColorNormalNoise ( double  tau = 0.05  )  [inline]

virtual ~ColorNormalNoise (  )  [inline, virtual]


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
See also:
add()

Reimplemented from NoiseGenerator.
