Unfortunately, I don't have the time at the moment to create a
tutorial nor do I have an example I can point you at. I can however
say that this should be doable using an unstructured grid or polydata
dataset. I guess you want to be able to create this using numpy
arrays rather than by creating a file. In this case maybe you should
take a look at tvtk:
http://svn.enthought.com/enthought/wiki/TVTK
which lets you create vtk datasets using numpy arrays. A simple
example is in the enthought/tvtk/examples/tiny_mesh.py that should get
you started.
