coordinate frame

[bmmi7]

Hi, I saw this line about coord frame conversion in splatfacto https://github.com/nerfstudio-project/nerfstudio/blob/fba4aa990342b019bb854da88cde3081b33a7f58/nerfstudio/models/splatfacto.py#L680

this seems the conversion btw opencv and opengl, but why it is applied there? and what is gsplat convention in the comment above this line.

thanks!

This is because nerfstudio uses the Blender / OpenGL convention, but gsplat uses OpenCV!

okay convert back again...

if I use colmap dataparser in nerfstudio for splatfacto, I should set assume_colmap_world_coordinate_convention=False and orientation_method=none?
