Built entirely with Claude Code, this WebGPU desert demo measures GPU cost by subsystem

A developer built a procedural desert explorer entirely with Claude Code and Three.js.
- The browser demo is a third-person desert world built from a GPU clipmap: no meshes, textures, or downloaded assets, with all terrain generated in shader code.
- Sand deforms permanently underfoot and erodes back over time; the experience also includes GPU cloth for a robe, a per-pixel sky simulation, and sand spells that carve craters and build rideable dunes.
- Claude Code was used for the whole stack: TSL shaders, compute kernels, physics integration, and Node tooling.
- The key workflow was giving Claude its own measurement tools: a headless Chrome harness booted the app, captured screenshots, and reported per-subsystem GPU cost so changes could be guided by numbers.
- The demo is live on a WebGPU-capable browser.
