noise functions

Noise functions are mathematical tools used to generate natural, random-looking patterns within digital environments. They produce smoothly varying values that mimic the irregularities found in nature, such as terrain shapes, clouds, or textures. Unlike pure randomness, noise functions create continuous and coherent patterns, making them essential in computer graphics and sound design for realistic effects. They are often used to add detail and variation while maintaining control over the overall structure, resulting in more organic and believable visuals or sounds in digital projects.
