why use origin [0.5, 0.5, 0.0] as the origin for lidar bbox about second.pytorch

[traveller59]

The origin of KITTI official label format is [0.5, 1.0, 0.5], after convert camera box to lidar by rect and transform matrix, the origin become [0.5,0.5, 0.0]. Change this shouldn't affect performance.
you may need to change lots of functions if you want to change this, be careful.

Thanks for the reply. As I am trying to use my own lidar data and it seems the center loc in annotation is at the actual center of the bbox. So I may need to change all [0.5,0.5,0.0] to be [0.5,0.5,0.5].

I will follow the logic of the code and try to modify it one by one.
Do you have any idea that where related function might be called?
