I want to read a VTR file and work with its data. In my case it has 3 Components,
source = XMLRectilinearGridReader(FileName=['test.vtr']) arrayName = 'M' arrayComponents = 3 data = source.GetCellDataInformation() array = data.GetArray(arrayName) dataRange = array.GetRange(component) FieldData = source.GetFieldData() print FieldData gives me: vtkPVDataSetAttributesInformation (000000000EAE6FC0) Debug: Off Modified Time: 1066787 Reference Count: 2 Registered Events: (none) RootOnly: 0 ArrayInformation, number of arrays: 1 Debug: Off Modified Time: 1068264 Reference Count: 1 Registered Events: (none) RootOnly: 0 Name: M DataType: 11 NumberOfComponents: 3 NumberOfTuples: 2500000 IsPartial: 0 Ranges : 0, 1.53585e+006 -1.53585e+006, 1.53585e+006 -1.53585e+006, 1.53585e+006 -306523, 1.53393e+006 InformationKeys : vtkAbstractArray::PER_COMPONENT vtkDataArray::L2_NORM_RANGE SortArrays: 1 Now I would like to access this data, best case for me would be if I can use it in numpy, with the from vtk.util.numpy_support import vtk_to_numpy methods... Or should I work with a Programmable Filter Option instead? Thanks Richard
