can I get kd_tree sorted pointcloud by kd_tree.py

[peterjohnsonhuang]

Hi, First,thank you for the contribution. I want to know that is it possible to get the sorted pointcloud by your code, since I found that the 'tree[-1]' output of make_cKDTree() is a pointcloud which have same size of input pointcloud and seemed to be spatial sorted. However, there are some overlapping points in it which makes it a little different from the original pointcloud. Thank you again. Best wishes
