Over the previous month it looks as if Gaussian Splatting (see my first post)
is experiencing a Cambrian Gaussian explosion of recent analysis. The seminal paper
got here out in July 2023, and beginning about mid-November, it looks like each day there’s a brand new paper or two popping out,
associated to Gaussian Splatting in a roundabout way. @MrNeRF and @henrypearce4D preserve a wonderful checklist of all issues associated to 3DGS,
try their Awesome 3D Gaussian Splatting Resources.

On no account an exhaustive checklist, simply random collection of fascinating bits:

Ecosystem and tooling


Unity Gaussian Splatting

The Unity Gaussian Splatting mission that I created with intent of
“eh, lemme attempt to make a fast toy 3DGS renderer in Unity, and perhaps mess around with knowledge dimension reductions”, has considerably surprisingly
reached 1300+ GitHub stars. For the reason that previous blog post it acquired a bunch
of random issues:

  • Help for HDRP and URP rendering pipelines in adition to the built-in one.
  • Nice grained splat enhancing instruments in type of choice and deletion (short video).
  • Excessive stage splat enhancing instruments in type of ellipsoid and field formed “cutouts”. @hybridherbst did the
    initial implementation, after which shortly afterwards all different
    3DGS enhancing instruments acquired just about the identical workflow. Good!
  • Means to export modified/edited splats again right into a .PLY file.
  • Quicker rendering by way of extra tight oriented screenspace quads, as a substitute of axis-aligned quads.
  • I made the gaussian splat rendering+enhancing piece an precise package deal (OpenUPM page),
    and clarified license to be MIT.
  • (not a part of github launch, however in newest fundamental department) Extra positive grained enhancing instruments (transfer particular person splats), potential to bake
    splat remodel when exporting .PLY, and a number of splats could be merged collectively.

The mission incorporates some bits that aren’t gaussian splat associated, however is likely to be helpful elsewhere:

Aaaand with that, I’m pondering that my toying round will finish right here. I’ve made a toy renderer and integration into Unity,
discovered a bunch of random issues within the course of, it’s time to name it a day and transfer onto one thing else. I think there will probably be one other
kphjillion gaussian splatting associated papers popping out over the following 12 months. Will likely be fascinating to see the place all of this finally ends up at!
