Questions tagged [perlin-noise]

Ask Question

Perlin noise is an algorithmic (computer-generated) effect developed by Ken Perlin, often used for simulating elements in nature and for procedural terrain generation, especially in situations with low levels of memory. It is also pseudo-random, and can be in any number of dimensions. An improved version of this now exists, also developed by Ken Perlin, and also covered by this tag - simplex noise.
