Perlin on Noise

A Perlin noise flame ballHere’s a lovely little presentation in which Ken Perlin talks about his noise function – Perlin noise – which he thought up while he was working on TRON (the original,) and which everyone in graphics uses when they want some vaguely naturalistic looking noise. Clouds, wall textures, height maps – it’s all Perlin.

He explains how he came up with it, the basics of how it works, and different ways to tweak it for different applications. Great stuff.
