Fractal noise is a type of noise that exhibits a self-similar pattern at different scales. It is often used in computer graphics and procedural generation to create natural-looking textures, such as clouds, mountains, and landscapes. Unlike regular noise, which appears random, fractal noise maintains a consistent structure, making it useful for simulating organic forms. This concept is closely related to fractal geometry, which studies shapes that repeat at various scales. Fractal noise can be generated using algorithms like Perlin noise or Simplex noise, allowing artists and developers to create complex and visually appealing environments in video games and simulations.
