A low-latency, procedurally generated 3D city environment running entirely on a custom client-side engine.

Built on top of Three.js and styled with a strict high-contrast design system, this experiment renders a dynamic urban grid populated by reactive AI agents. To ensure consistent 60+ FPS performance even on mobile WebGL contexts, the rendering pipeline leverages a flat distance-squared culling sweep every 10 frames, a single-pass hemisphere lighting layout, and medium-precision WebGL buffers to completely eliminate garbage collection spikes. Standard rigid physics calculations are replaced by a fast Body-Center-Offset raycast alignment loop, keeping movement, collisions, and dynamic spatial audios instantly responsive.
