I am trying to display arrow (using vtkArrowSource) on the vtkHandleWidget as
follow:
vtkArrowSource *arrSrc = vtkArrowSource::New();
vtkPolygonalHandleRepresentation3D *axes =
vtkPolygonalHandleRepresentation3D::New();
axes->SetHandle(arrSrc->GetOutput());
vtkSmartPointer<vtkHandleWidget> widget =
vtkSmartPointer<vtkHandleWidget>::New();
widget->SetRepresentation(axes);
widget->SetInteractor( renderWindowInteractor );
widget->SetEnabled( 1 );
but nothing comes on screen.
Instead if I use vtkOrientationMarkerWidget in place of vtkHandleWidget I
can see the arrow:
vtkArrowSource *arrSrc = vtkArrowSource::New();
vtkPolygonalHandleRepresentation3D *axes =
vtkPolygonalHandleRepresentation3D::New();
axes->SetHandle(arrSrc->GetOutput());
vtkSmartPointer<vtkOrientationMarkerWidget> widget =
vtkSmartPointer<vtkOrientationMarkerWidget>::New();
widget->SetOrientationMarker( axes );
widget->SetInteractor( renderWindowInteractor );
widget->SetEnabled( 1 );
What could be the reason of vtkArrowSource not working with vtkHandleWidget.
