Perlin-Noise

Perlin Noise is a fractal noise function based on pseudo-random Gradientwerten. Through the seemingly random appearance of Perlin Noise This is often used in image synthesis to simulate natural phenomena such as clouds, landscape topologies or water. Perlin Noise is based on the superposition of frequencies. At the highest usable frequency of a different value is calculated for each pixel. The lower the frequency, the more values ​​have to be interpolated between the two pixels, resulting in a shallower gradient.

The texture synthesis goes back to Ken Perlin, who developed it in 1982 for the film Tron, for which he won an Oscar in 1997.

Successor

In 2001, Perlin introduced the Simplex Noise, which requires less computing power.
