Claude Sonnet 5.5 turns one prompt into a three.js scene
From a single sentence, Claude Sonnet 5.5 built a real-time three.js scene with rotating dome, falling snow, stars, orbiting camera, and code-generated ambient music.
No 3D models. No textures. No stock music. Just a sentence. I wanted to see how far a single short prompt goes with zero downloaded assets: "a quiet observatory on a snowy mountain at night" Claude Sonnet 5.5 turned it into a real-time 3D scene in three.js: a rotating dome, falling snow, a warm lit window, a field of stars and a camera slowly circling it all. The ambient track was generated by code too. Honest notes: → The first render had a tree blocking the camera, blown-out snow and square snowflakes. A few fixes later, this is the result. → It's low-poly, not Pixar. But it's one sentence and a few tweaks. Why I tried it: everyone's comparing AI models on 3D demos lately, and I wanted to see what one short prompt actually gets you.
