Voxel Collision in SuperSplat
Will Eastcott tweeted about implementing voxel collision in the SuperSplat editor, a tool for editing and viewing Gaussian splatting scenes. The feature allows for accurate collision detection within the voxel-based editing environment.
Background
- **Will Eastcott** is a co-founder and former CEO of PlayCanvas, an open-source 3D game engine that runs in the browser.
- **SuperSplat** is a free browser-based 3D editor for gaussian splatting scenes (a technique for rendering photorealistic 3D scenes from photographs). It was created by PlayCanvas.
- A "voxel collision" system in SuperSplat would let users define simple collision volumes (block-based hitboxes) inside a 3D scene, enabling basic physics interactions — things like characters walking on surfaces, objects bouncing off walls, or cursor picking.
- This matters because gaussian splatting scenes are usually just visual (a "point cloud" you can fly through), with no physics or interactivity. Adding voxel collision bridges that gap, making splats usable in games and interactive experiences.
