Noise Type

Four types of noise are available:

Noise

Turbulence

Turbulence is composed of several frequency bands of summed noise.

Wavy Turbulence

Wavy Turbulence is the same as Turbulence, except that the changes are more abrupt (wavefronts).

Fractal Brown Movement

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.

Positive Only

When active, only positive values will be output.
