[vtkusers] plotting contour of 3D numpy array.

[picca]

Hello

I am a newbie in the vtk community so sorry if this question have
already been solved in the mailing list.

In fact I am using pyvtk and I tryed to use the Contour3 object for a 3D
numpy matrix.

but I need a x, y, and z array and I only have a 3D numpy array like
this one

m = numpy.array((120, 120, 66))

How can I just plot this matrix ?
