You can use tvtk/mayavi2 for this. Here are examples of unstructured
grids that you can take a look at:
A polygonal data set with pure TVTK:
https://svn.enthought.com/enthought/browser/branches/enthought.tvtk_2.0/examples/tiny_mesh.py
A 3D unstructured grid where data is generated with tvtk and viewed
with Mayavi2:
https://svn.enthought.com/enthought/browser/branches/enthought.mayavi_2.0/examples/unstructured_grid.py
The nice thing about both is that they integrate well with numpy
arrays and use views of your numpy array data.
For more information on the tools see:
