Hmm, true. I violated my own principle of trying not to do too much in the constructor. However, you should be able to figure out how to use the underlying utility functions compute_planes() and linear_interpolate_grid() from the LinearInterpolator code and Triangulation's docstring to describe its attributes. -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco ------------------------------------------------------------------------------ Register Now for Creativity and Technology (CaT), June 3rd, NYC.
