My name is Inigo Quilez, I was born and grew up in San Sebastián (a.k.a. Donostia), a beautiful city in the Basque Country, in Europe (Spain). I enjoy mathematics, computer graphics and skiing (you can beat me at computer graphics, but not at skiing), among other things. I have a resume, a Shadertoy account, a Youtube channel, a Facebook page and a Twitter stream.

I like playing with computer graphics, then create articles, video tutorials and demos with the learnings, and share them on this page. If you want to support me, you can do so in Patreon where you'll also get updates on what I'm doing and links to private LIVE tutorial stream. You can also do a one time payment in PayPal, or you can also buy some prints of my works, in Redbubble.

Lastly, if you plan to use any of my shaders commercially, or need some consulting for your startup, company of film studio, or coaching for your projects, please contact me at so we can discuss it.


This is the place where I host articles, tutorials, code, and presentations related to maths, fractals, demoscene and computer graphics.
video tutorials

Video tutorials and live coding sessions on using maths to create images. Some of the live coded ones are almost a decade old, from before live coding was trendy!

These are the libraries and frameworks that I use for my C++ and JS demos, experiments and products. I do update these often. Also, use at your own risk.

If you want to buy high quality framed prints or posters of my shaders, you can order them here in different sizes, finishings and prices.

This is where I archived the demoscene pieces I created from 1998 to 2012, mostly featuring realtime rendering and procedural content.

Shadertoy is a website that I co-created together with Pol Jeremias where you can create, share and learn realtime computer graphics.

With Graphtoy you can design, graph and explore mathematical functions, which is very useful during procedural and shader programming.

This is not a blog on computer graphics. it's more of a place for me to write thoughts on maths, life, politics, society and other topics that cross my mind.
