Explanation of close/far depth bounds during generation of the .npy file

[EarltShirt]

Hello, thanks for your great documentation, I'm currently working on generating a npy file suiting your criterias. My main problem is determining and computing the close/far depth bounds : What are they, how can I compute or find them ? Thanks a lot for your time.
