The possibility to use a nerfstudio trained gaussian splat

[abrahamezzeddine]

Hello,

I am wondering if it is possible to use an already trained nerfstudio splat instead of having to train a gaussian splatting with this model and append/export the semantic segmentation into another splat model or something like that?

Nerfstudio creates a COLMAP structure as well as a finished .ply file.

The splat model has following attributes, which I assume are similar to the original 3DGS model?

Sure, it's a good idea. I will try to add this function later to let OmniSeg3D-GS use the available Gaussian splat file.
