Support for Spacetime Gaussians (4D)?

[mkleijn]

Hi, I was wondering if there are any plans of implementing support for 4D Gaussian splats, as described in this paper ?

That would be cool.

No plans at the moment, but I agree that it would be very cool; time-varying splats definitely seem like a promising area of research right now, and I'd love to see MetalSplatter be extended in that direction eventually.

Hi, I just recently implemented Deformable-3D-Gaussians on MetalSplatter, it is also one of the famous 4D Gaussian work. If you are interested, you can have a look at this fork. But I am a complete newbie to Swift, Metal, and MPSGraph so many things are not really optimized.

thanks for this great work. Is there any news on the 4DGS implementstion possiblity?

Thank you for sharing this fork and implementation @yunjinli, I haven't had a chance to take a look while I've been prioritizing getting MetalSplatter 1.0 out, but plan to take a look soon!
