Yes. We have demos working already. Those 3D gaussian videos (or 4D that some people call) are really big so we're figuring out what's the best way to distribute and make it a great experience.
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 future it might be possible to use a single camera and have an AI/ML method figure out how all the 3D gaussians move over time, including parts that are occluded from the single camera!
