Running on NeRF Synthetic Dataset

[ChikaYan]

Dear Authors,

Thank you so much for the brilliant work and for sharing the code!

May I ask if it is possible to run the code on NeRF synthetic dataset? Specifically, when loading the camera poses "cam_world_pose" from meta jsons, does the code expect the cam_world_pose to be in Blender format, or openGL format? What is the difference between "cam_world_pose" and "transform_matrix" in NeRF synthetic dataset?

Many thanks!
