楼主
使用vtkAxesActor和vtkOrientationMarkerWidget在QVTKWidget中添加一个坐标系，出现了如图所示的错误，将vtkOrientationMarkerWidget这段注释掉就能运行成功，求各路大神指点指点
主要代码如下：
vtkSmartPointer<vtkNamedColors> colors =
vtkSmartPointer<vtkNamedColors>::New();
vtkSmartPointer<vtkSphereSource> sphereSource =
vtkSmartPointer<vtkSphereSource>::New();
sphereSource->SetCenter(0.0, 0.0, 0.0);
sphereSource->SetRadius(1.0);
sphereSource->Update();
vtkPolyData* polydata = sphereSource->GetOutput();
// Create a mapper
vtkSmartPointer<vtkPolyDataMapper> mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputData(polydata);
// Create an actor
vtkSmartPointer<vtkActor> actor =
vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
// A renderer and render window
vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();
vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->SetWindowName("Display Coordinate Axes");
renderWindow->AddRenderer(renderer);
ui.qvtkWidget->SetRenderWindow(renderWindow);
// Add the actors to the scene
renderer->AddActor(actor);
renderer->SetBackground(colors->GetColor3d("SlateGray").GetData());
// Create an axesActor and widget
vtkSmartPointer<vtkAxesActor> axes =
vtkSmartPointer<vtkAxesActor>::New();
vtkSmartPointer<vtkOrientationMarkerWidget> widget =
vtkSmartPointer<vtkOrientationMarkerWidget>::New();
double rgba[4]{0.0, 0.0, 0.0, 0.0};
colors->GetColor("Carrot", rgba);
widget->SetOutlineColor(rgba[0], rgba[1], rgba[2]);
widget->SetOrientationMarker(axes);
widget->SetInteractor(renderWindow->GetInteractor());
widget->SetViewport(0.0, 0.0, 0.2, 0.2);
widget->SetEnabled(1);
widget->InteractiveOn();
renderer->GetActiveCamera()->Azimuth(50);
renderer->GetActiveCamera()->Elevation(-30);
renderer->ResetCamera();
