Why voxel generator use reverse_index? #76

Closed tianweiy closed 4 years ago

tianweiy commented 4 years ago

line here the reverse_index is set, so that the returned coordinates is zyx format, I am wondering why we want to use reverse_index?

I found similar issue in the spconv repo (https://github.com/traveller59/spconv/issues/62#issue-455566367) and wonder if anyone figures out the reason.
