See repo for prompt. Feel free to contribute to format or benchmarking. MIT Open Source.
Doesn’t with for me, iOS Safari :/
It's working on Android Chrome browser
The viewer uses WebGPU... I could support WebGL for greater compatibility.
Something’s way off with these numbers. The page says it encodes video at 640MB/s which is quite large even for 4D data and doesn’t match the filesize of the demo splat (7.4MB / 2sec, or ≈3.4MB/s).

In fact they say the raw file size of the demo splat was only 427MB, so maybe the 640MB/s was a statement about encode speed? Why write it that way instead of “this demo splat was encoded in 0.6sec” or even just “the time to produce the original splat took longer than the time to encode this video format”?

A gaussian gif. Coming to porn sites soon. The file format name works for them. But imagine whole movies shot in this format. The fly-on-the-wall fantasy of movies, without being locked in place for the whole shot. Narrative possibilities like being able to examine just how close the Tyrannosaurus Rex is to your rear view mirror. Clues in a mystery only visible on rotation. Hidden bonus scenes.

I hope this catches on just to be able to watch the evolution of cameras to capture it.

So a video game?
A video game playthrough in a file, game not needed.
I feel like I did this one already: https://github.com/seanwevans/4splat
Wow dude. That is a hell of a README. Great job!
Admittedly just scanned this but that’s lossless, right?
Do you know what kind of compression ratios you get out of curiosity? Presumably it would be lower than this format (because this format is meant to be lossy not lossless) but very curious as a baseline.
Your readme is really mobile unfriendly, FYI
Does switching scenes in the demo work for anyone? There are what, 3 hidden panels in the HTML there? But none of them have a "switch scenes" button.
Whats the 4 in the "4D" here? A layman like me thinks this looks 3D.
The application is cool, but there is little novelty here. All of the employed techniques are well-established.

I suggest removing "novel" from the title unless you wish to seriously disappoint some people.

I tried to apply existing mp4 H265 like compression to 3D splats. Do you have any links to other 4D splat formats?
I'm so tired of HN putting sites on the top with zero human authorship. I have to listen to Claude-voice enough at my job.
> a splat is static iff a single quantized value

What is up with LLMs and "iff"?
