Series
Apple's GPU API, built up from the smallest thing that draws to a finished renderer — Veta, a kart racer for the Mac whose world is a flat map seen in perspective, the way Mode 7 drew one. Twelve posts in four parts: the basics, the things you reach for once the first triangle works, Metal 4 and the fallback that keeps the game running without it, and three on shaders. Every listing is code that ships.
