Detailed Description

A collection of methods to sample Value Noise.

All noise methods instead produce values from 0 to 1.

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.
