The PointClouds objects can be clustered.

Basic K-means clustering

after selecting a point cloud and clustering it, the new created point clouds are added to the graph.

public void Kcluster(){
 BoundedCloud c = (BoundedCloud) first((* pc:de.grogra.pointcloud.groimp.PointCloud, 
    (pc.getCloud() instanceof BoundedCloud) *)).getCloud(); 
 Cloud[] res = de.grogra.pointcloud.tools.KMeans.cluster(c,2,4);
 for(Cloud y : res){
 [
  ==>>^y;
 ]
 }
}
