[vtkusers] QVTKWidget Camera vs vtkOrientationMarkerWidget

[Luis Vieira]

Now I did other test, just taking of the of the code Ren1.ResetCamera() and Ren1.Render() and the exception is the following:

 

First-chance exception at 0x00007FFF82201433 (vtkRenderingCore-7.0.dll) in vKoreStructuralVectoringD.exe: 0xC0000005: Access violation reading location 0xFFFFFFFFFFFFFFFF.

Unhandled exception at 0x00007FFF82201433 (vtkRenderingCore-7.0.dll) in vKoreStructuralVectoringD.exe: 0xC000041D: An unhandled exception was encountered during a user callback.

 

 

viewPortAxActor->GetXAxisCaptionActor2D()->GetCaptionTextProperty()->SetColor(1, 1, 1);

              viewPortAxActor->SetXAxisLabelText("E");

              viewPortAxActor->GetXAxisCaptionActor2D()->SetWidth(0.05);

              viewPortAxActor->GetXAxisCaptionActor2D()->SetHeight(0.05);

              viewPortAxActor->GetYAxisCaptionActor2D()->GetCaptionTextProperty()->SetColor(1, 1, 1);

              viewPortAxActor->SetYAxisLabelText("N");

              viewPortAxActor->GetYAxisCaptionActor2D()->SetWidth(0.05);

              viewPortAxActor->GetYAxisCaptionActor2D()->SetHeight(0.05);

              viewPortAxActor->GetZAxisCaptionActor2D()->GetCaptionTextProperty()->SetColor(1, 1, 1);

              viewPortAxActor->SetZAxisLabelText("Up");

              viewPortAxActor->GetZAxisCaptionActor2D()->SetWidth(0.05);

              viewPortAxActor->GetZAxisCaptionActor2D()->SetHeight(0.05);

 

              vtkSmartPointer<vtkOrientationMarkerWidget> viewPortOMWidget = vtkSmartPointer<vtkOrientationMarkerWidget>::New();

              viewPortOMWidget->SetOrientationMarker(viewPortAxActor);

              viewPortOMWidget->SetInteractor(mainViewPort->GetInteractor());

              viewPortOMWidget->SetViewport(0.7, 0.0, 1.00, 0.3);

              viewPortOMWidget->SetEnabled(1);

              viewPortOMWidget->InteractiveOn();

 

              //Ren1->ResetCamera();

              //Ren1->Render();

              

              //mainViewPort->GetRenderWindow()->GetInteractor()->Start();

Hi Luis,

Try setting the interactor from the widget: 

myWidget ->SetInteractor(myQVTKWidgetCAmera->GetInteractor());

Hello vtkusers,

 

Anybody knows how to use vtkOrientationMarkerWidget with QVTKWidget interactor? I have been trying to implement the VTK example (http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/DisplayCoordinateAxes) and it worked smoothly. However, within  my QVTKWidget Camera, and I caught  the following exception:

 

ERROR: In C:\VTK\VTK-7.0.0\GUISupport\Qt\QVTKInteractor.cxx, line 147

QVTKInteractor (000000F46583D670): QVTKInteractor cannot control the event loop.

 

Following my vtkOrientationMarkerWidget snapshot:

vtkRenderWindow* renwin = vtkRenderWindow::New();

myQVTKWidgetCAmera->SetRenderWindow(renwin);

Ren1 = vtkRenderer::New();

myQVTKWidgetCAmera->GetRenderWindow()->AddRenderer(Ren1);

 

vtkAxesActor* myAxActor = vtkAxesActor::New();

vtkSmartPointer<vtkOrientationMarkerWidget> myWidget = vtkSmartPointer<vtkOrientationMarkerWidget>::New();

              myWidget ->SetOrientationMarker(myAxActor);

              myWidget ->SetInteractor(myQVTKWidgetCAmera->GetRenderWindow()->GetInteractor());

              myWidget ->SetViewport(0.7, 0.0, 1.00, 0.3);

              myWidget ->SetEnabled(1);

              myWidget ->InteractiveOn();

 

Ren1->ResetCamera();

Ren1->Render();

              

myQVTKWidgetCAmera->GetRenderWindow()->GetInteractor()->Start();

 

Thank you very much for any help,
