Noise

Noises are useful for the development of procedural effects specially with a natural and organic appearance, such as clouds, water movement, landscapes and marble textures.

Perlin Noise

Section titled “Perlin Noise”

Perlin Noise has revolutionized digital design by creating natural-looking textures and patterns. Unlike random noise, Perlin Noise produces smooth, coherent variations, making it ideal for simulating organic structures. This technique, developed by Ken Perlin in the early 1980s, was first used to generate realistic textures for the movie Tron.
