Question related to 3D mesh models in general: has any significant work been done on models oriented towards photogrammetry? Case in point, I have a series of photos (48) that capture a small statue. The photos are high quality, the object was on a rotating platform. Lighting is consistent. The background is solid black. These normally are ideal variables for photogrammetry but none of the various common applications…

48 images is an incredibly small number for high quality photogrammetry. 480 wouldn’t be overkill. A couple of hundred would be considered normal.

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.
