55 GPU lessons from hello-window to SSAO, each a standalone C program with Claude Code skills baked in.

Strengths

•Comprehensive progression from fundamentals to advanced (SSAO, shadow mapping implied) respects learning curve; each lesson is runnable and self-contained.
•"Why not just what" philosophy and Claude Code skills mean AI agents can actually build on these patterns instead of hallucinating graphics code.
•Modern SDL GPU API is timely; most graphics tutorials still teach OpenGL or WebGL, not current SDL3 production path.

Weaknesses

•Audience is inherently niche: SDL3 GPU is new, and graphics programming attracts a small slice of developers.
•No shipped game projects or portfolio proof-of-concept showing these lessons produce real-world output beyond standalone demonstrations.

Post Description

Open-source tutorial series teaching real-time graphics programming with SDL's GPU API. Covers everything from Hello Window to SSAO, with math lessons, engine lessons, and a UI track building font rendering from scratch. Every lesson is a standalone C program with commented code explaining why, not just what. The whole project was built with Claude Code. Each lesson also distills into a reusable Claude Code skill — copy them into your own project and build games with AI that actually understands the GPU patterns.
