此代码是选择器actor。一旦选择了一个actor,它就会打印相应选定actor的高位。问题是在交互器中禁用旋转和拖动,我想要包含它。

// Handle mouse events
class MouseInteractorStyle5 : public vtkInteractorStyleTrackballActor
{
    public:
    static MouseInteractorStyle5* New();
    vtkTypeMacro(MouseInteractorStyle5, vtkInteractorStyleTrackballActor);

    virtual void OnLeftButtonDown()
    {
        // Forward events
        vtkInteractorStyleTrackballActor::OnLeftButtonDown();

        for (auto it = actors.begin(); it != actors.end(); ++it)
        {
            if(this->InteractionProp == (*it))
            {
                std::cout << "Actor high: " << (*it)->GetMapper()->GetInput()->GetPoint(0)[2] << std::endl;
            }
        }

    }
    std::vector<vtkSmartPointer<vtkActor>> actors;
};

vtkStandardNewMacro(MouseInteractorStyle5);

void actorsMouseInteractor(const std::vector<vtkSmartPointer<vtkActor>> & actors)
{
    // A renderer and render window
    vtkSmartPointer<vtkRenderer> renderer =
      vtkSmartPointer<vtkRenderer>::New();
    vtkSmartPointer<vtkRenderWindow> renderWindow =
      vtkSmartPointer<vtkRenderWindow>::New();
    renderWindow->AddRenderer(renderer);


    // An interactor
    vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
      vtkSmartPointer<vtkRenderWindowInteractor>::New();
    renderWindowInteractor->SetRenderWindow(renderWindow);

    // Set the custom stype to use for interaction.
    vtkSmartPointer<MouseInteractorStyle5> style =
        vtkSmartPointer<MouseInteractorStyle5>::New();
    style->SetDefaultRenderer(renderer);
    style->actors = actors;

    renderWindowInteractor->SetInteractorStyle(style);

    renderer->AddActor(getPlatformActor());
    for (auto it = actors.begin(); it != actors.end(); ++it)
    {
        renderer->AddActor(*it);
    }
    renderer->SetBackground(.1, .2, .4);
    renderWindow->Render();
    renderWindow->SetSize(renderWindow->GetScreenSize());
    renderWindowInteractor->Start();
}

输出例如是Z中的位置:

演员高:1.800
