[CVPR 2024] Official PyTorch implementation of SuGaR: Surface-Aligned Gaussian Splatting for Efficient 3D Mesh Reconstruction and High-Quality Mesh Rendering (by Anttwo)

Project mention: GaussianObject: Just Taking Four Images to Get a High-Quality 3D Object | news.ycombinator.com | 2024-02-21

As with all NeRFs and Gaussian Splatting, there is no classical mesh data. But there are projects and papers working on the extracting process. Specifically for Gaussian Splatting there is SuGaR. [1]

geogram

a programming library with geometric algorithms

Project mention: Voronoi Diagram and Delaunay Triangulation in O(nlog(n)) (2020) | news.ycombinator.com | 2023-10-25

Interesting question! By virtue of being a tree, the MST produces at most 3 edges coming out of any vertex, so this should be the same in 3D. The MST then adds (sometimes) a 4th edge, so, although you could build both graphs in 3D space, you would still end up with 4 edges coming out of any vertex, I think.
In 3D space the Delaunay triangulation would produce a bunch of irregular tetrahedra, so the edges coming out from every vertex would vary between a minimum of 3, and a maximum of 12, if I get it right (ref: [1] :-).
The 3D Voronoi cells are another story... I found some implementation that you can play with to see how it looks [2] [3], each cell is of a shape called "convex polytope". It feels like these cells are packed like each of the sub-cubes of a rubik, but I'm not 100% sure :-) ... if that's true, you could jump from each vertex to the next in at most 17 directions? (hand-waves :-p)
