Turbulence filter.
Library: ilvbmpflt
This bitmap filter lets you create images using the Ken Perlin turbulence function. It allows synthesis of natural textures such as cloud or marble. The basic algorithm sums for each pixel the values of a pseudo-random function using different scales and frequencies. You can specify the number of repetitions (octaves), the frequencies in each direction, and whether the filter generates turbulence of fractal noise. See "Texturing and Modeling", Ebert et al, AP Professional, 1994.
