Mrdoob's Interactive Ball Pool Simulation
Article: NeutralCommunity: Very PositiveConsensus

This page features Ball Pool, an interactive physics simulation created by mrdoob. It includes a direct link to the project's source code on CodePen for editing and experimentation. The demo showcases dynamic movement and collision detection in a web browser environment.
Key Points
- The project is an interactive physics simulation called Ball Pool.
- It was developed by the prominent web creator mrdoob.
- The source code is hosted and editable on the CodePen platform.
Sentiment
Overwhelmingly positive. The Hacker News community is genuinely impressed by the demo's visual quality and cross-device performance. Technical commenters appreciate the rendering innovations, and the few criticisms are minor notes about SSGI quality and browser compatibility rather than fundamental objections.
In Agreement
- The demo showcases impressive real-time rendering quality that would have required dedicated hardware just years ago, now running smoothly in a browser
- Three.js's new WebGPU-based SSGI and TRAA nodes represent meaningful progress in web graphics capabilities
- The demo runs well across a surprisingly wide range of devices including phones, laptops, and older PCs
- Mrdoob's long history from Flash-ActionScript to three.js to this demo represents an inspiring arc in web graphics
Opposed
- The SSGI implementation is slow for what it is, especially without denoising, and shadows appear grainy
- WebGPU on Firefox/Linux can cause serious issues including system freezes and desktop environment flickering
- Some question what makes this demo particularly special or noteworthy beyond being a polished tech showcase
