[vtkusers] How to put 3D geometry object in vtkImagePlaneWidget?

[Jochen K.]

Hi kooitt,

I assume your cone is simply too tiny and therefore invisible.
I would size the cone according to the bounds of the volume. For instance:

double bounds[6];
reader->GetOutput()->GetBounds(bounds);

cone->SetHeight((bounds[1] - bounds[0])/ 3);
cone->SetRadius(cone->GetHeight()/3.14);

with best regards
Jochen
