Using Claude Opus 5 for Massive Crowd Rendering in the Browser
willeastcott · x · 2026-07-30
A developer used Claude Opus 5 via vibe coding to build a massive army scene running in a browser tab.
The project was created to test two new features added to the PlayCanvas engine:
- Crowd rendering: Rendering a whole army in a single instanced draw call.
- Volumetric fog.
This demonstrates how LLMs can be used to quickly generate code for complex 3D engine feature testing and web-based graphics experiments.
