Cell

Cell noise is a versatile VSL object, which is especially useful in bump mapping. Cell noise is a combination of 'noise bubbles' in 3D space. It has the following options:

  • Octaves: The amount of iterations in cell noise computation. The final cell noise is a sum of several iterations of cell computation. Every iteration has 'Octave ratio' times higher frequency and lower amplitude.

  • Base value: Defines the base value of the noise signal.

  • Amplitude: Defines the maximum range from the base value.

  • Amp. Variation: The amount of random variation in amplitude between cells. 0 = All cells have equal amplitude, 1=Amplitude varies from zero to maximum amplitude.

  • Size: The relative size of cells. The size 0.5 produces cells that do not overlap but slightly touch each other (if variations are zero).

  • Size variation: The amount of variation in cell size. 0=all cells have equal size, 1=size varies between zero and the maximum value defined by Size.
