Nerfstudio Releases gsplat 1.1

Roughly five weeks after the release of gsplat 1.0, the Berkeley based team are back with a new update to their Gaussian Splatting method, gsplat.

This release comes with several updates, with the highlight being able to choose the densification method utilized. Users will be able to pick from the default method, absgrad, or MCMC.

New users will also be happy to know that a guide to installing gsplat on Windows is also contained in this update and can now be found on the ReadMe page of gsplat.

For a full look at the changelog, please see below:

Multiple densification strategies are now supported in gsplat, including

• DefaultStrategy(): The original 3DGS densification process.

• DefaultStrategy(absgrad=True): Densification process from “AbsGS: Recovering Fine Details for 3D Gaussian Splatting”

• MCMCStrategy(). Densification process from “3D Gaussian Splatting as Markov Chain Monte Carlo”
