Floater Free Gaussian Splats

[abrahamezzeddine]

Is your feature request related to a problem? Please describe.
This is not really an issue because it might be an inherent problem in the initial development of gaussian splats but I am wondering if there is any plan to implement a floater free functionality for gaussian splats? When rendering a room for example, there is a lot of free floaters in the air. Culling this depending on alpha helps a little bit, but there are still plenty. Providing such solution would really put this application at the forefront of developing good gaussian splats.

Describe the solution you'd like
Perhaps delete floaters that have no "semantic" meaning? Such as automatically removing outliers in the point cloud before creating the splat itself?
