With VTK you can use texture maps to texture a polygonal dataset. You
could just as easily specify the data attributes along the surface of
the sphere and visualize that. You could do this as either a
structured grid, polygonal data set or an unstructured grid depending
on the nature of the data you have. You might want to read the
section on creating data files here:
http://mayavi.sourceforge.net/docs/mayavi_talk.pdf
You might want to try out tvtk
(http://svn.enthought.com/enthought/wiki/TVTK) if you are looking for
a Pythonic way to create your data set.
cheers,
