3D cluster visualization

Hi,

This is a question about the MDS 3D cluster visualization that gCluto implements. I'd like to map and display certain points from my high-dimensional space (I'm clustering documents retrieved over Medline) directly on the 3D surface, in other words add more information to it.

I'm aware that it's probably not possible with the current version of gCluto, that's why I'd like to know if it could be done using some other package (for R or Matlab for instance). The way I see it, I would import Cluto's output (the command-line version) in that other tool, and plot the height map with the customization I need.

Thank you for your help and for putting such high quality software publicly available,

Christian
