Procedural three.js world with sound and free-roam browser demo
Continuing the experiment: the most complex fully procedural world I can get out of three.js. Zero downloaded assets, sound included. This time the lead is Opus 5.5. One prompt + a reference image → a plan. Then I kicked off 3 plan steps by hand. Never asked it to fix anything. What you see is the first pass, zero correction rounds. 3h36m active · 445 requests · +5,010 lines · ~$60 at API pricing Reference in the replies 👇 #threejs #tsl
