r.surf.fractal(1)

NAME
r.surf.fractal

DESCRIPTION
r.surf.fractal creates a fractal surface of a given fractal dimension. Uses spectral synthesis method. Can create intermediate layers showing the build up of different spectral coefficients (see Saupe, pp.106-107 for an example of this).

Use this module to generate naturally looking synthetical elevation models (DEM).

NOTE
This module requires the FFTW library for computing Discrete Fourier Transforms.
