Fastest Perlin-Like 3D noise algorithm?

Question

It\'s been well over 20 years since Ken Perlin first invented his noise. Has anybody managed to make a faster kind of 3D noise generator with properties close to Perlin\'s (

Answer 1

You want Simplex Noise.

• less computationally expensive
• not based on a square grid, so no obvious directional artifacts
• scales better to higher dimensions: O(N^2) vs Classic Perlin's O(2^N) for N dimensions

There's a good explanation here. Apparently Ken Perlin's example implementation is not the most easy to understand code.
