FW: [vtkusers] vtkImagePlaneWidget

[Toon Huysmans]

Hi Dean,

	I tried your suggestion and it indeed transforms the widget but
it does not give the desired result:  the widget is transformed but it
slices the image at the transformed location instead of at the original
location.

The thing I want to achieve is like the registration visualization in
Amira: there the moving image is transformed and it is visualized by
slicing the transformed image using an orthogonal plane set.  This way
you can check if the registration was good without resampling the moving
image.  You can see what I mean in the attached figure.


Thanks,

Toon.

Hi Toon,

if what you want to do is specify the 
positioning of the widget's
underlying vtkPlaneSource, then do:

widget->SetOrigin(my_origin_point);
widget->SetPoint1(my_u_axis_point);
widget->SetPoint2(my_v_axis_point);
widget->UpdatePlacement();
