Perlin's Noise Algorithm
Summary
The article explains what noise is, distinguishes random noise from coherent noise, and then walks through Perlin's Noise algorithm. It includes step-by-step explanations of gradients, permutation tables, dot products, and interpolation, with code snippets and visual examples. It serves as a practical tutorial for procedural texture generation in 2D graphics and game development, as well as historical context about Perlin's algorithm.
