[vtkusers] importing unstructured grid data from numpy array

[Florian Bruckner]

hello,

I would need a method to read unstructured grid data from a numpy array.
Does anyone know a function like vtkImageInputFrom/ExportToArray.py that
also handles unstructured grids? or is there a possibility to transform
image data to unstructured grids?

i only found the tvtk library, but in order to use it I will have to
install the whole ETS project. In addition the documentation of this
library mention that it is more 'pytonic' to use tvtk but that it should
also be possible to do the same things with pure vtk.

thanks 
FloB
