Hi Nil,
try this:
vtkRenderWindow *renderWindow =
mitk::BaseRenderer::GetRenderWindowByName("stdmulti.widget4");
axes = vtkSmartPointer<vtkAxesActor>::New();
widget = vtkSmartPointer<vtkOrientationMarkerWidget>::New();
widget->SetOrientationMarker(axes);
widget->SetOutlineColor(0.9300, 0.5700, 0.1300);
widget->SetInteractor(renderWindow->GetInteractor());
widget->SetEnabled(1);
widget->InteractiveOn();
It looks good to me, but we have never really tested if there are side
effects when using interactive vtkWidgets in the QmitkRenderWindow
If you don't want to move or resize the widget in the running
application, I recommend to call:
widget->InteractiveOff();
Regards,
Christoph

Hi all, is there a way to add a vtkOrientationMarkerWidget to the 3D
view? I successfully added a vtkAxesActor with this code
vtkRenderWindow *renderWindow =
mitk::BaseRenderer::GetRenderWindowByName("stdmulti.widget4");
mitk::BaseRenderer* renderer =
mitk::BaseRenderer::GetInstance(renderWindow);
vtkSmartPointer<vtkAxesActor> axes = vtkSmartPointer<vtkAxesActor>::New();
renderer->GetVtkRenderer()->AddActor(axes);
But it's useless without a vtkOrientationMarkerWidget.
So I try to add the following code (mostly from
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/DisplayCoordinateAxes)
vtkSmartPointer<vtkOrientationMarkerWidget> widget =
vtkSmartPointer<vtkOrientationMarkerWidget>::New();
widget->SetOrientationMarker(axes);
widget->SetOutlineColor(0.9300, 0.5700, 0.1300);
widget->SetInteractor(renderWindow->GetInteractor());
widget->SetEnabled(1);
widget->InteractiveOn();
The application always crashes in vtkOrientationMarkerWidget .cxx,
ExecuteCameraUpdateEvent() near line
vtkCamera *cam = this->CurrentRenderer->GetActiveCamera();
I think it's because this->CurrentRenderer is a bad pointer, something

Oh, if there's an MITK way of displaying the axis in the 3D view, it's
even better! Thanks for your time.
