GPT-6 Astra + Three.js demo generates 3D trains entirely in code at runtime
gaganghotra_ · x · 2026-09-05
A demo by @tomkrcha combines GPT-6 Astra with Three.js: no 3D model files at all — both trains are generated at runtime from TypeScript/Three.js code using dimensions, profiles, and geometry functions, with wheel motion and explode/reassemble animations fully code-driven, running smoothly in the browser. The author argues we've moved beyond static models to "engineering living worlds in code."
