About the translation of camera in HyperNeRF dataset and coords convention

[MobiusLqm]

Hi, Thanks for your wonderful work.

1. in your codes line 164-165 of scene/hyper_loader.py , you use T = - camera.position @ R instead of T = camera.position ,Could your please tell What's the reason behind it?
2. Addtionaly, as far as i know , 3d gaussian splatting uses opencv coords convention, but hypernerf dataset uses openGL convention. Why don't you convert it to opencv coords? Looking forward to your reply! Regards.
