Description

's site is the written-tutorial archive for graphics, maths, fractals, and demoscene work, with links to videos, Shadertoy shaders, and utilities. Quilez co-founded Shadertoy and documents techniques from demoscene and industry R&D.

Topics include SDF raymarching, distance primitives, procedural noise, path tracing, voxels, filtering, lighting, fractals, and 4k sizecoding, often with compact GLSL snippets for any real-time shader host.

Aimed at advanced programmers and technical artists comfortable with fragment-shader math; explanations assume vectors and implicit surfaces, not a particular game engine.

Articles are free, grouped in on-site indices, with MIT-licensed code snippets; shader artwork is licensed separately. YouTube tutorials complement the written pages.

Widely cited as the standard reference for distance-field formulas and raymarching in real-time graphics.
