PhysStudio
A pile of runnable physics animation recreations: lightning, melting ice, flowing water, falling snow, pouring — all as Gaussian splatting scenes.
PhysStudio is a collection of runnable physics animation recreations: lightning striking a woodpile, ice melting and freezing back, rain wetting a scene, flowing lava, sand mixed into water, wind in the trees, magnets grabbing rigid bodies, a robot pouring water, thin-film bubbles, and more — over twenty small projects, each with code, a run guide, and a rendered demo video. Each one recreates a published physics simulation paper: the visuals are rendered with 3D Gaussian Splatting and the physics runs on NVIDIA Warp. You can click into any project in the repo to watch the animation preview, and if you’re interested, follow the guide to run it yourself and tweak the parameters. The repo belongs to Zhejiang University’s 3D vision group (zju3dv), and the first line of its README says plainly that this is a vibe-coded world simulator. The latest commit was November 4, 2026, with several new demos added between November 3 and 5, and it has 28 stars on GitHub. Note that this is not ready-to-use software — it’s a pile of research-style recreation code. You have to set up Python 3.10 yourself, install Warp, download the assets, and you’ll need a decent graphics card to run it. If you just want to play with it, the demo videos in the repo are enough.
