hello, I am intertsted in your great work.Thanks. I have a problem about what does "ret_unique_cnt" mean?
“ret" and "cnt" are short for what?

Hi,

This is a part of PointNet++. ret - return cnt - count ret_unique_cnt - returns the number of unique points that were selected in the grouping operation of PointNet++. So if you send in N points and ask for K groups, ret_unique_cnt determines the number of unique points in each of the K groups.
