Hi ! Maybe I am an old-fashion programmer, but I don't think you are allowed to initialized an array in this way. The braces should delimit constant values... The best I can remember, the compiler should outputs errors for your line :
double Tuple[3] = {xm_array -> GetValue(i), ym_array -> GetValue(i), 0.0}; Which one do you use? Then for your specific problem, I recommend you to use the InsertNextTupleValue from vtkDoubleArray instead of InsertNextTuple, that is a pure virtual function of the parent class vtkDataArray. I hope expert programmers will take a look at this !
