Browser-tab real-time particle VFX, no engine: why AI building games as code changes everything
TheMoonMidas · x · 2026-09-07
A demo running entirely in a browser tab — no engine, no install: six spells with real-time particle simulation, refracting ice geometry, and a live VFX editor where every parameter is tunable while the scene runs. The argument: the shift is that AI now writes geometry and shaders as code instead of asset files — a game of .fbx files is one AI can only rearrange, a game of code is one it can edit. The full procedurally generated game came out under 2MB before audio. The quoted article covers "GPT-6 Astra" (unverified claims, read with caution).
