Shortly after the inclusion of OpeNeRF into Nerfstudio another method has been added. This time it's NeRFtoGSandBack, which allows for the shuttling between NeRFs and 3DGS within Nerfstudio.

The command for OpenNeRF is quite simple, with it using: ns-train nerfsh. There is not yet any indication how much VRAM NeRFtoGSandBack takes to run.

The foundation that Nerfstudio has created makes it easy for authors to open their methods up to the public to try them out. If you are a researcher or just want to implement a method, Nerfstudio has provided documentation on how to do so. The full documentation page for From NeRFs to Gaussian Splats, and Back can be found here.

From NeRFs to Gaussian Splats, and Back comes with an Apache 2.0 license to match Nerfstudio, making it easy for people to build ontop of and use commercially.
