If you’ve been using 3D Gaussian Splatting (3DGS) to create 3D representations of an environment, you might be familiar with the challenge of “floaters,” which can be very difficult to remove.

In this article, we demonstrate how to train your 3DGS model using MCMC combined with a bilateral grid to achieve “floater-free” 3D models. We provide a detailed explanation of the paper “3D Gaussian Splatting as Markov Chain Monte Carlo,” covering all the equations and derivations step by step.
Additionally, we show how to seamlessly insert small objects into a large 3D Gaussian environment using techniques like background segmentation and Gaussian manipulation.
