Detailed Description

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 double getTau | ( | ) | [inline, virtual] |
| 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.
