When I try to transform the "Collection" grid from cartesian coordinates to cylindrical coordinates using the following script:
pdi = self.GetInput() pdo = self.GetOutput() newPoints = vtk.vtkPoints() numPoints = pdi.GetNumberOfPoints() for i in range(0, numPoints): coord = pdi.GetPoint(i) x, y, z = coord[:3] r = x * cos(y) t = x * sin(y) newPoints.InsertPoint(i, r, t, z) pdo.SetPoints(newPoints) pdo.GetPointData().AddArray(pdi.GetPointData().GetArray(0)) pdo.GetPointData().AddArray(pdi.GetPointData().GetArray(1)) pdo.GetPointData().AddArray(pdi.GetPointData().GetArray(2)) I get the following error: Traceback (most recent call last): File "<string>", line 26, in <module> File "<string>", line 7, in RequestData AttributeError: GetPoint The script works well if the grid is not of GridType Collection.
