How to Create Physics Simulations with Vibe Coding | GPUSims

Physics simulation using Vibe Coding

In this tutorial, I walk through the complete "vibe coding" workflow to build a high-performance 3D N-body physics simulation running directly in the browser.
Using WebGPU and AI, we can separate the mathematical formulation from the rendering mechanics, making it incredibly fast to bring complex STEM concepts to life without writing every line of WGSL code from scratch.

We use GPUSims to handle the heavy lifting of the WebGPU pipeline while the AI focuses on the physics algorithms.
I will show you exactly how to prompt for a schema, generate the compute shaders, and even have the AI write a full educational article about the observable phenomena in the simulation.
