4DGS Renderer

A Gaussian splat reconstruction of a garden, showing a round wooden table, planting, and a brick house behind it.

A dynamic scene playing back in the player, frame-time overlay running.

Gaussian splatting is a way of capturing real places in 3D that looks photoreal, but it doesn't work with normal mesh-based renderers. DGS-JS is a renderer that plays those scenes in a browser on WebGPU.

Highlights

  • Millions of splats re-sorted every frame, off the main thread in a Web Worker.
  • A WGSL compute pass that drops the splats you can't see and writes its own draw calls, so the CPU never stalls.
  • Plays dynamic scenes, splats that move over time rather than a static capture.
  • Published on npm as a single HTML element, decoding .dgs through WebAssembly.
