what's the coordinate convention for the extrinsic in the rendered dataset?

[yshen47]

Thanks for sharing the rendered dataset. We managed to download the dataset in the provided google drive link. However, we trained on nerfstudio using provided extrinsic, but the coordinate frame of extrinsic seems not follow standard Blender coordinate system? Could you share more details on how you prepare the extrinsic? Are you generate all the data using render/render.py?
