Clustering 3D point cloud

Hello Rooters,

I am having a 3D point cloud, and i would like to detect how many cluster are there.

So are there any classes available in ROOT that provides clustering of 3D point.
or if there are classes that allows me to get Voronoi Diagram of 3D points.


You can draw the Delaunay triangles but not the voronoi diagram.
There is parallel coordinates plots (via TTree) which are good at showing clusters.

Thanks couet,
Is there any example of parallel plot in Root Tutorial. So that i can get idea about how can i get clusters

Thanks couet,
I will go through, but will it work for 3D points also.

parallel coordinates are meant to be used with N-Dimensions.
