vtkPerlinNoise

Section: Visualization Toolkit Filtering Classes

Usage

vtkPerlinNoise computes a Perlin noise field as an implicit function. vtkPerlinNoise is a concrete implementation of vtkImplicitFunction. Perlin noise, originally described by Ken Perlin, is a non-periodic and continuous noise function useful for modeling real-world objects.

The amplitude and frequency of the noise pattern are adjustable. This implementation of Perlin noise is derived closely from Greg Ward's version in Graphics Gems II.

To create an instance of class vtkPerlinNoise, simply invoke its constructor as follows

  obj = vtkPerlinNoise
