[vtkusers] vtkActor::GetCenter() Problem

[Wenlong Wang]

Dear all,

I'm running the example here
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Filters/TransformPolyData . There
are two spheres created from vtkSphereSource.

I create two arrays* double p1[3]* and *double p2[3]*. After the renderer
add these two actors, I applied vtkActor::GetCenter() to them. However, I
found the returned points are all (0, 0, 0). But they are obviously in
different position. So does that mean the returned value is the model
coordinates?

Many thanks in advance.

Best wishes
Wenlong
