Hi! My question is pretty simple: What are some good ways to generate random N-dimensional gradients for Perlin noise?
Posted 30 January 2013 - 06:16 AM
Something purely algorithmic like mod289 is usually good enough for Perlin noise if you can't (or don't want to) afford a lookup texture.A lookup texture can represent N dimensions by atlassing, see chapter 2.1 of Shader X7.
