There are a lot of tools to do this easily today, for free! Take a look at Postshot, or Brush. You can literally take a video with your mobile phone, toss it in Postshot, and a few…

Yeah you're right, using float16 gets us 0x7C00 buckets of resolution only. We could explicitly turn it into a log encoding and spread it over 2^16 buckets and get 2x the range the…

We have a WebXR demo we built during Spark's development that showcases 3DGS running on Quest 3 or Vision Pro: https://lofiworlds.ai Make sure to enable hand tracking so you can "t…

I'm one of the developers of Spark, a new open-source 3D Gaussian Splatting renderer (sparkjs.dev). While developing Spark, we built a WebXR demo that lets you experience a stream …

It's an interesting idea, and with spark you could test this by adjusting the parameter maxStdDev to control how far out it draws the splat. I agree with you though that in general…

We are purposefully trading off some sorting precision for speed with float16, and for scenes with large Z extents you'd probably get more Z-fighting, so I'm not sure if I'd recomm…

Spark allows you to construct compute graphs at runtime in Javascript and have them compiled and run on the GPU and not be bound by the CPU: https://sparkjs.dev/docs/dyno-overview/…

Most 4DGS reconstruction methods right now are exactly that: setting up many cameras and recording them simultaneously so you can reconstruct each instant in time as a 3DGS. In the…

Yes, Spark does instanced rendering of quads, one covering each Gaussian splat. The sorting is done by 1) calculating sort distance for every splat on the GPU, 2) reading it back t…
