This noise module outputs concentric cylinders centered on the origin. These cylinders are oriented along the y axis similar to the concentric rings of a tree. Each cylinder extends infinitely along the y axis.
This noise module, modified with some low-frequency, low-power turbulence, is useful for generating wood-like textures.
Output values are between -1 and 1.
Frequency : increasing the frequency reduces the distances between cylinders.
Frequency = 1
Frequency = 10
