In that case you might have to learn how to program and use VTK.  This
will definitely take a little time and effort.  If you do plan on
using VTK then I'd recommend that you get familiar with Tcl, Python or
Java.  My personal favorite is Python.  Once you get handy with the
programming language, learn how to script VTK applications with it and
you should be able to do what you want.  OTOH if C++ is your strength
and you dont want to bother with learning another language just write
your application in C++ using VTK.  The VTK users guide and the VTK
book should guide you through this.  As I said, either way this will
take some work.

How are your data points organized (are they structured or
unstructured)?  Either way, VTK can handle them.

If you are looking for a readymade solution look at Sebastien's links
page (http://www.barre.nom.fr/vtk/links.html) and look for an
application that suits your needs.  You might want to take a look at
