Description

An interactive 3D historical simulation of a Tupinambá war fleet paddling through the Bertioga channel, featuring dynamic weather, historically accurate attire, and procedural wildlife. The project was directed by the author through a fleet of 32 AI agents that managed research dossiers, Three.js coding, and Blender scripting.

Why this is interesting: Extreme technical ambition using 32 parallel agents to achieve high historical accuracy in a complex WebGPU 3D scene.

Prompt

Clone dgreenheck/tidewater. He made a really good visual experiment with Opus 5.5 and I want something at the same level, but in pre-colonial Brazil: a Tupinambá going up a river into enemy territory, set in Pindorama. The idea of this folder is to make several demos portraying historical moments of humanity with three.js and 3D. Do you think we’re capable not only of producing this level of 3D visuals in the browser, but also of doing the correct historical research?
