Feature: Dynamic Gaussians

[Winter-Dry]

What a amazing work!!!!!!

I have thoroughly enjoyed using it and have found it to be an essential component in rendering with Three.js. I believe it has great potential.

I wanted to bring to your attention a feature that I believe would significantly enhance the functionality and user experience of this project. After careful consideration and feedback from fellow users, I suggest the addition of SpacetimeGaussians. I believe that this enhancement would make this repository even more versatile and appealing to a broader audience.

With both statistic and dynamic 3D Gaussians, I find myself even more excited about the possibilities this enhancement could bring.

Thank you for your time and consideration.

This certainly does look very cool! I currently have several features I plan on adding in the near future, so something like this would have to wait until after those are done, but in terms of the mid-term to long-term road map, this looks like something worth considering. I'll have to dig into it a bit more.

@mkkellogg happy to help/fund development of this feature!

I'm lumping in another issue into this one: #115. I think 4D support is something I'd like to support long-term, possibly using an approach like this one: https://fudan-zvg.github.io/4d-gaussian-splatting/

@mkkellogg I think this is a great idea and will have wide implications. Video models like openAI sora are getting very good and this feature might become a critical piece in the future of content creation
