What do you think about the sparse voxel approach, shouldn't it be more compute efficient than computing zillions of ellipsoids? My understanding of CGI prolly is t0o shallow but I wonder why it hasn't caught on much..

I believe most of the "voxel" approaches also require some type of inference (MLP). This limits the use case and ability to finely control edits. Gaussian splatting is amazing because each Gaussian is just a point in space with a rotation and non-uniform scale.

The most expensive part of Gaussian splatting is depth sorting.
