Description

Inigo Quilez's Articles page collects written tutorials on procedural graphics, mathematics, and shader utility code at iquilezles.org/articles. It complements his YouTube channel and ShaderToy work with reference-style pages on noise, raytracing, distance functions, voxels, compression, and index utilities.

Major sections include signed-distance functions in 2D and 3D with analytic gradients, smooth boolean blending, domain repetition, procedural noise families, raymarching filtering fixes, point-cloud and splatting notes, and size-coding tricks. Many pages link to matching ShaderToy demos in public playlists.

Utility code snippets on the site are MIT-licensed for reuse in production shaders; artistic shader results are not automatically licensed for commercial use without separate permission. Articles emphasize efficient, branch-minimal formulas derived by Quilez himself.

Pages are free to read online with optional Patreon or PayPal support. The SDF catalog in particular is treated as a standard reference when implementing raymarching or procedural modeling in games and tools.

Widely regarded in the graphics and demoscene communities as essential reference material for SDFs and procedural primitives; code from these pages appears throughout production and hobby shaders worldwide.
