If you're interested in shader coding, you've likely come across the work of XorDev. He's best known for GM Shaders, a shader programming resource for GameMaker. As a professional Graphics Programmer, he works on shader effects across games, the web, and software, sharing his expertise and techniques.

A few days ago, he gave the community a great gift by publishing all of his tutorials on FragCoord, an online shader-sharing platform he made as an alternative to Shadertoy. The platform has been available since February of this year and receives new publications from users every day.

These aren't really step-by-step tutorials, they're legacy GM Shaders' deep dives into math concepts for graphics programming, shader fundamentals, and procedural techniques, covering things like noise, ray marching, fractals, and beyond. There's also Xor's collection of "Minis": 21 ready-made shaders you can use for different effects, including glass, tiles, halos, mosaics, and more.

Check out XorDev's tutorials here, and follow him on X/Twitter for tweet-sized GLSL "code golfing" shaders and more cool content:
