55 C lessons on SDL's GPU API — written with Claude Code

WHAT IT SOLVES

SDL3 shipped a brand-new GPU abstraction layer. Docs are sparse, tutorials basically don't exist, and the only real path is diving into source code blind

WHY IT'S INTERESTING

★ Volume as quality

55 lessons — from hello triangle to full pipelines

Not a single demo — a full progressive curriculum. 55 standalone C files, each teaching one GPU concept. The author treated SDL3's GPU API as the subject of a deep study, not a passing experiment. That's commitment

★ The irony

Low-level graphics tutorials, built with AI

The most interesting tension here: these lessons teaching you to hand-roll GPU calls in C were built with Claude Code. One person used an AI coding tool to create a curriculum in one of the hardest programming domains. In a way, the repo itself is a live demo of where AI assistance actually works — and where it still needs a human who knows the domain
