GPT-6 Astra : V2 intégral contre V1 hybride

Create a single-page Three.js experience that makes me say “what the fuck”. The goal is to demonstrate the absolute maximum of your capabilities as a coding model, visual designer, technical director and multi-agent orchestrator. Build one coherent real-time 3D experience, not a collection of disconnected demos. It should feel like an interactive AAA technical showcase running inside a browser. You are free to choose the concept, art direction, architecture, interactions, shaders, simulations, camera work and technical stack around Three.js. Use your subagents aggressively. Delegate different areas of the project to specialized agents, allow them to work independently, review their work, challenge weak implementations and combine the strongest ideas into one coherent result. The final experience should demonstrate as many relevant advanced techniques as possible when they genuinely improve the result: procedural generation custom GLSL shaders GPU particles instancing advanced lighting post-processing cinematic camera work physics or simulations complex animation interactive environments spatial audio responsive interactions high-end UI integrated into the 3D world performance optimization Do not make a portfolio. Do not make a landing page. Do not make a dashboard. Do not create several small experiments. Create ONE unforgettable experience. Visual quality matters more than feature count. Continuously inspect the result yourself and iterate until it looks intentional, polished and technically impressive. The final result must run locally and be immediately usable.
