The ActiViz product supports 2D and 3D triangulation via Delaunay methods. 
The classes vtkDelaunay2D and vtkDelaunay3D do this. You will have to 
create a vtkPolyData (with points, etc). and feed it to the classes. Once 
they execute (via Update() method) the output contains the triangulation.

There are other methods for resampling points as well such as the surface 
reconstruction filter and shepard's method.

I think it's great, nothing like having a cool program inside a power point 
slide. Of course I'm biased :-)
