Spheres

Noise module that outputs concentric spheres.

@image html modulespheres.png

This noise module outputs concentric spheres centered on the origin like the concentric rings of an onion.

The first sphere has a radius of 1.0. Each subsequent sphere has a radius that is 1.0 unit larger than the previous sphere.

The output value from this noise module is determined by the distance between the input value and the the nearest spherical surface. The input values that are located on a spherical surface are given the output value 1.0 and the input values that are equidistant from two spherical surfaces are given the output value -1.0.

An application can change the frequency of the concentric spheres. Increasing the frequency reduces the distances between spheres. To specify the frequency, call the SetFrequency() method.

This noise module, modified with some low-frequency, low-power turbulence, is useful for generating agate-like textures.

This noise module does not require any source modules.
