Are the camera extrinsics normalized s.t. pointcloud is zero-centered?

Hello,

I noticed that the camera extrinsics provided by the [Co3D dataset are adjusted s.t. the pointclouds are zero-centered.](https://github.com/facebookresearch/co3d/issues/64) Have the camera extrinsics for the CoP3D dataset been adjusted in a similar way (CoP3D's pointclouds don't seem be zero-centered).

Start by reading the linked Co3D issue and comparing its description of camera extrinsics with the CoP3D pointclouds mentioned here. Done means establishing whether CoP3D uses the same zero-centering adjustment and documenting a clear answer for the dataset users.
