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.
Thank you,
Nikos

The grid is declared as GridType Collection. When I read it in
Paraview the grid is read correctly as shown in the attached
picture, however I don't get the values for the attribute. I
think the attribute is not read at all. Is there sth wrong with
this file? How should the attribute be specified for GridType
Collection?
Thank you,
Nikos
