Four types of noise are available:
Turbulence is composed of several frequency bands of summed noise.
Wavy Turbulence is the same as Turbulence, except that the changes are more abrupt (wavefronts).
Fractal Brown Noise is the same as Turbulence, except that its high frequency bands are weaker.
Noise values can be output not only contingent upon animation time but also contingent upon coordinates. This offers the advantage that different values can be output within a given frame. In the example above, individual noise values are output for each object point.
As with turbulence, only minimal strength at higher frequencies.
When active, only positive values will be output.
