Íñigo Quílez — 4K intros to Shadertoy
iq (Íñigo Quílez) pushed real-time raymarching in the demoscene's 4K intros, then carried those techniques to the wider world by co-creating Shadertoy and working in film graphics.
Overview
iq — Íñigo Quílez — is the rare scener whose techniques escaped the scene entirely and reshaped how a generation thinks about real-time graphics. With Rgba he made some of the most admired 4K intros ever, including Elevated, rendering whole lit landscapes from a few thousand bytes by raymarching signed distance fields.
He then took those ideas mainstream. Quílez co-created Shadertoy, the in-browser playground where countless people first learned shader programming, and has worked in film and graphics research. The maths he sharpened to fit a demo in 4 kilobytes now turns up in tutorials, tools, and production renderers everywhere.
Fast facts
- Handle: iq.
- Group: Rgba.
- Discipline: Real-time graphics; raymarching / signed distance fields.
- Beyond the scene: Co-creator of Shadertoy; film and graphics work.
Why iq matters
Quílez is the clearest single example of demoscene technique becoming general knowledge. The size-coding discipline forced elegant, procedural solutions, and those solutions — distance fields, procedural texturing, compact lighting — proved far too useful to stay locked inside 4K intros.
