Squared euclidean distance in sided_distance()

[benemer]

Hi,

In kaolin/kaolin/metrics/pointcloud.py it says that the sided_distance() method computes

For every point in p1 find the indices and euclidean distances of the closest point in p2.

However, it seems like the underlying _C.metrics.sided_distance_forward_cuda returns the squared euclidean distance. Can you please clarify this?

Thank you

Is this challenge still pending? I would love to begin from here.
