Detailed Description

A collection of methods to sample Perlin Noise.

The single-frequency Perlin noise methods produce values from -1 to 1. The multi-frequency Perlin noise methods instead produce values from 0 to 1.

Turbulence noise is a variant of Perlin noise where the absolute values of multiple frequencies are summed.

Tiled versions have offsets used for moving the tiling area to another spot in the noise domain. For the tiling dimensions, the integer parts are used to offset the cells, while the fractional parts are used to offset sampling within the tile. Animating these offsets will result in popping when they cross integer boundaries as the sampling switches to another tile. Frequency and lacunarity are integers for the tiled versions because they must be aligned with cell boundaries.

The 3D Perlin noise code is based on Ken Perlin's Improved Noise reference implementation. The 2D versions use 16 gradients, which produces a slightly more wavy pattern than the 3D versions.
