That does not really address the problem with set_active_attribute(). > goal? Why are you doing this isosurface? I want to find points where two contours intersect: where real and imaginary parts of my Phi both = 0. To simply look for |Phi|=0 is not useful since it would require extrapolation (I am not guaranteed to have a point |Phi|=0 in my data, in fact, I am almost guaranteed NOT to have such a point). So, I turn extrapolation problem into an iterpolation problem by first taking one contour of the first array, changing the active attribute and taking another contour. Since now the first contour has filtered out all points NOT on the first contour, the second contour gives me the intersections of the two. I tried to look for VTK filters to do something similar, but could not find any. I do not even want to plot anything, just find those points. Mayavi is well suited for that since it does the interpolation for me as well.
