Building an Interactive WebGL Fluid Simulation App with Claude

vinishkapoor · reddit · 2026-08-12

A developer leveraged Claude to build a complete interactive web experience based on Pavel Dobryakov's open-source WebGL Fluid Simulation engine (MIT licensed).

With Claude's assistance, the developer constructed a custom UI layer (including a settings panel, auto-animate mode, and screenshot capture), full-screen mode, responsive design, and front-end visual polish. The application renders fluid dynamics based on Navier-Stokes equations in real-time via WebGL shaders, supports click-and-drag interaction, and is completely free with no ads.
