Funny, it almost sounds like a straight efficiency improvement of Plenoxels (the direct predecessor of gaussian splatting), which would mean gaussian splatting was something of a a red herring/sidetrack. Though I'm not sure atm where the great performance gain is. Definitely interesting.

How is plenoxels a direct predecessor of gaussian splatting?

They both emerged out of the pursuit of a more efficient solution for addressing the inefficiencies in NeRF, which was mainly due to expensive ray marching and MLP calls. Before the emergence of Gaussian splatting, grids, such as plenoxels were all the rage. Of course, Gaussian splatting here refers to the paper, “3D Gaussian Splatting for Real-Time Radiance Field Rendering”
