2. 代码实现
代码如下:
class CellPickerInteractorStyle : public vtkInteractorStyleTrackballCamera
{
public:
static CellPickerInteractorStyle* New();
CellPickerInteractorStyle()
{
selectedMapper = vtkSmartPointer<vtkDataSetMapper>::New();
selectedActor = vtkSmartPointer<vtkActor>::New();
polyData = vtkPolyData::New();
//xvec.resize(5);
//yvec.resize(5);
//zvec.resize(5);
last_picked_actor = NULL;
}
virtual void OnLeftButtonDown()
{
//打印鼠标左键像素位置
if (this->Interactor->GetControlKey())
{
std::cout << "Picking pixel: " << this->Interactor->GetEventPosition()[0]
<< " " << this->Interactor->GetEventPosition()[1] << std::endl;
//注册拾取点函数
this->Interactor->GetPicker()->Pick(
this->Interactor->GetEventPosition()[0],
this->Interactor->GetEventPosition()[1], 0, // always zero.
this->Interactor->GetRenderWindow()->GetRenderers()->GetFirstRenderer()
);
//打印拾取点空间位置
this->Interactor->GetPicker()->GetPickPosition(picked);
cout << "Picked value: " << picked[0] << " " << picked[1] << " " << picked[2] << endl;
//获取此次的标记点。
this->last_picked_actor = GetActor();
markPoint.push_back(last_picked_actor);
if (this->last_picked_actor)
{
//标记出来
this->last_picked_actor->SetScale(0.02);
this->last_picked_actor->GetProperty()->SetColor(1.0, 0.0, 0.0);
this->Interactor->GetRenderWindow()->GetRenderers()->GetFirstRenderer()->AddActor(this->last_picked_actor);
}
}
vtkInteractorStyleTrackballCamera::OnLeftButtonDown();
}
};
int main(int, char* [])
{
// Read a stl file.
reader1->SetFileName("bunny.stl");
reader1->Update();
TheStlPoly->DeepCopy(reader1->GetOutput());
// Create a mapper and actor
vtkSmartPointer<vtkPolyDataMapper> mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputData(TheStlPoly);
actor->SetMapper(mapper);
actor->GetProperty()->SetOpacity(1);
// Create a renderer, render window, and interactor
vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();
vtkSmartPointer<vtkRenderWindow> renderWindow = vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->Render();
renderWindow->SetWindowName("PointPicker");
renderWindow->AddRenderer(renderer);
vtkNew<vtkNamedColors> colors;
renderer->SetBackground(colors->GetColor3d("CadetBlue").GetData());
vtkSmartPointer<CellPickerInteractorStyle> pointPicker = vtkSmartPointer<CellPickerInteractorStyle>::New();
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor = vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetInteractorStyle(pointPicker);
renderWindowInteractor->SetRenderWindow(renderWindow);
// Add the actor to the scene
renderer->AddActor(actor);
//renderer->SetBackground(0, 0, 0);
// Render and interact
renderWindow->Render();
renderWindowInteractor->Start();
return EXIT_SUCCESS;
}
