OpenCode builds 3D browser helicopter game

AI coding agents are quickly advancing past simple scripting tasks and are now capable of generating rich, multi-layered interactive 3D games with complex state management.

* Complex Assets and Math: Generating a 3D flight engine, collision physics, and altimeter telemetry in Three.js showcases the agent's strong mathematical and geometric reasoning.

* Agentic Orchestration: Building a multi-module game from scratch requires deep context retention and logical consistency across layout, logic, and state rendering.

* Low-Barrier Prototyping: Showcases like this indicate that high-fidelity gaming prototypes can now be built by developers in hours instead of days using agentic coding helpers.
