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

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

The center of concentric spheres is the 0,0,0 coordinate (upper left corner in 2D representations). If you want to center the spheres, you have to use the Shifter modifier using -0.5x -0.5y -0.5z values.

Output values are between -1 and 1.
