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.
Thanks for the links. Going to check them out this morning.
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.
Expect a lot of progress over the next couple of years.
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.
