CloudCompare forum

I'm trying to understand the distance between these two points. I understand the distance is 0.4 between points but the other values I do not understand ?

I was looking at Peel 3D by Creaform an impressive programs for 3D scanning data although expensive. Some features as found on the software main page is the ability to split off an object among other things that I can't completely describe available in Cloud Compare ?

I want to find the distance between points but in the tree the point cloud is disabled therefore how can I enable and select points on the mesh to find the distance ?
