Cluster/Aggregate Points

Post by markallan »

Hi,

Is there a function that will allow me to identify 'clusters' of points based on a search radius? For example, I currently have a single point cloud with clusters of points across a surface and large empty spaces between them. I'd like to select all points that fall within 1m of each other and separate them into a separate cloud. When the distance to the next cluster is >1m, then it would be a separate cluster.

Thank you for any help!

There's a 'connected components' method (http://www.cloudcompare.org/doc/wiki/in ... Components). It's only limitation is that you can't set a precise distance between the clusters (just an octree level) which roughly correspond to this distance.
