Hi list,

I have a 3 dimensional numpy array describing a sort of MRI image.
I woud like to fetch the vertices and faces of an iso_surface plot for some
contour as numpy arrays? Is it possible?

I've been ducktyping for a while trying to understand the structure of the
object returned by mlab.pipeline.iso_surface and ended up in some VTK
structures that are somewhat hard to understand without any docstring!

Is there any other python alternative to mayavi for this task?

Thank you!
Vincent
