Hello, After staring at http://www.paraview.org/Wiki/Python_Programmable_Filter for a while, the way to access the data for a specific variable name still eludes me. This is the python code from the wiki on Add the Colors variable to a PolyData
============================= input = self.GetPolyDataInput(); output = self.GetPolyDataOutput(); colors = vtk.vtkUnsignedCharArray(); colors.SetNumberOfComponents(3); colors.SetName("Colors"); numPoints = input.GetNumberOfPoints() for i in range(0, numPoints): colors.InsertNextTuple3(255,0,0); output=input output.GetPointData().AddArray(colors) =============================== How do I from the next filter, access the variable name "Colors" that I created? Any help is much appreciated. thanks -simon
