Perlin Noise

Perlin noise is a type of gradient noise developed by Ken Perlin in 1983. It has many uses, including but not limited to: procedurally generating terrain, applying pseudo-random changes to a variable, and assisting in the creation of image textures. It is most commonly implemented in two, three, or four dimensions, but can be defined for any number of dimensions.

How to interact: Click the canvas to generate a new random noise pattern. Each pattern is created using coherent noise that produces organic, flowing shapes.

Applications:

• Terrain height maps for landscapes and mountains
• Cloud and fog textures
• Procedural wood and marble patterns
• Natural-looking randomness in games and animations

Unlike pure random noise, Perlin noise creates smooth transitions between values, making it ideal for natural phenomena simulation.
