Seed function and pass any number in the interval [-2²⁴, 2²⁴-1]¹ After you have decided the dimensions that you are From this github page I can see you are actually able to pass a seed as an argument to the OpenSimplex class. 4. cs I. As a matter of probability, it is increasingly rare to get values near -1 or 1, especially with smooth noise such as OpenSimplex. perlin4: 4-dimensional perlin noise. 0. I'm saying OpenSimplex has worse complexity than Simplex Noise due to a larger kernel size. The algorithm borrows the surflet summation idea from Simplex noise, but is based off of the lattice of a Simplectic Honeycomb instead of a skewed scissor-simplex lattice, and uses a slightly larger surflet radius. The implementation includes 2D, 3D and 4D noise. In a virtualenv (see these instructions if you need to create one): pip3 install opensimplex This resource allows you to configure and sample a fractal noise space.
