Projecting pixels in the renders (depth maps together with the camera_matrices) generated by blender back to 3d point cloud

Thank you so much for sharing the blender_script ! I was wondering what is the version of blender that is used.

To build own training data, it would be really appreciated if you could share more about how to re-built the 3d point clouds from the renders and camera matrices generated by blender.
