Augmentation code in openpcdet can't be used for point cloud that created by LiDAR scanning

[Tony-syr]

This is in fact not a question, It is an information
I have read the code of the data augmentor and I found that they use the normal transmission rules to do the scaling and rotation, or even copy objects from scene to scene: I list the reason here:
1- In LiDAR point cloud, a local rotation of some points will result in an odd object in the scene, which changes the points' distribution.
2- A LiDAR point cloud is a discontinuous world, thus we can not use a random angle (a) for global rotation, the angle (a) suppose to satisfy the condition: a = n T where T is the horizontal resolution of the scanner, n is an integer number.
3- In the LiDAR point cloud, we can not do shifting of any kind, it changes the object's surface that is scanned by LiDAR.
