Recently, a lot of development in this area has been in gaussian splatting and from what I have seen, the new methods are super effective. https://en.wikipedia

Yeah some very impressive stuff with splats going on. But I haven't seen much about going from splats to high quality 3D meshes. I've tried one or two with pretty poor results.

  There have been a few papers published on the topic, but it's "early days". Expect a lot of progress over the next couple of years.

    Splats to meshes is an isosurface extraction problem, fundamentally. It's one of the great unsolved problems of computer graphics and having a good general algorithm would have massive ripple effects for any problem involving meshes. It's a rabbit hole and I only really understood it when I realized that the minimum time between any GH committer's hobby example and implementing the 2003 state-of-the-art is ~4 years. Fingers crossed that Gaussian Splatting makes the rewards high enough that resources get poured on this.

The parent explicitly asked for a mesh.

  The second link I posted contains n flow from splats to meshes

  You can never be sure what someone's real intent is. They might mean "something meshlike". Personally I usually reply by asking for more info (I always have the XY Problem in my mind) but that is time consuming and some people assume you're being pendantic (I am however correct more often than not - people have posed the wrong question or haven't given critical parts of the context)

    Yeah, I am explicitly asking about meshes, which is why I said that and also referenced photogrammetry. Sometimes people know what they're asking for help with. Thanks for the links. Going to check them out this morning.

      Just to be clear I wasn't singling you out. I don't know anything about you. And furthermore I also often post questions that lack sufficient context. My point was that it's always okay to ask for clarification or to assume that there was maybe some broader contact context or to offer a suggestion that doesn't follow the most literal interpretation of the question as asked.
