C# Class LibNoise.Primitive.SimplexPerlin

Noise module that outputs 3-dimensional Simplex Perlin noise. This algorithm has a computational cost of O(n+1) where n is the dimension. It's a lost faster than ImprovedPerlin (O(2^n)) Quality is not used here. This noise module outputs values that usually range from -1.0 to +1.0, but there are no guarantees that all output values will exist within that range.

Inheritance: ImprovedPerlin, IModule4D, IModule3D, IModule2D
