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 (see init()) p1  first parameter for random number distribution p2  second parameter for random number distribution Reimplemented in ColorUniformNoise, ColorNormalNoise, and SineWhiteNoise. Definition at line 93 of file noisegenerator.h.

virtual double generate (  double  p1, double  p2 )  [pure virtual]

generate somehow distributed random number between parameterized with p1 and p2 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 See also: add() Reimplemented in ColorUniformNoise, and ColorNormalNoise. Definition at line 76 of file noisegenerator.h.

double uniform (  double  min = -0.1, double  max = 0.1 )  [inline, protected]
