鼠标点击左键进行交互的方法
第一种方法:
继承原来的交互样式,对其中进行修改

class MouseInteractorStyle : public vtkInteractorStyleTrackballCamera
{
public:
static MouseInteractorStyle* New();
vtkTypeMacro(MouseInteractorStyle,vtkInteractorStyleTrackballCamera);
virtual void OnLeftButtonDown(void);
};
vtkStandardNewMacro(MouseInteractorStyle);//必须加!!!! 如果不加,使用vtkSmartPointer会进行报错
void MouseInteractorStyle::OnLeftButtonDown(void)
{
vtkInteractorStyleTrackballCamera::OnLeftButtonDown();
printf("left button down\n");
}
//class MouseInteractorStyle : public vtkInteractorStyleTrackballActor
// {
// public:

// vtkTypeMacro(MouseInteractorStyle,vtkInteractorStyleTrackballActor);
// virtual void OnLeftButtonDown(void);
// };
// vtkStandardNewMacro(MouseInteractorStyle);//必须加!!!!
// void MouseInteractorStyle::OnLeftButtonDown(void)
// {
// vtkInteractorStyleTrackballActor::OnLeftButtonDown();
// printf("left button down\n");
// }

{

//===================圆柱的
vtkSmartPointer<vtkPolyDataMapper> cylinderMapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
cylinderMapper->SetInputConnection( cylinder->GetOutputPort() );
vtkSmartPointer<vtkActor> cylinderActor =
vtkSmartPointer<vtkActor>::New();
cylinderActor->SetMapper( cylinderMapper );
//设置圆柱的颜色
cylinderActor->GetProperty()->SetColor(1.0, 0.0, 0.0);
//==================渲染器

//将圆柱actor添加到渲染器中
renderer->AddActor( cylinderActor );
//设置渲染场景的背景颜色 也就是窗口的颜色
renderer->SetBackground( 1.0, 1.0, 1.0 );
vtkSmartPointer<vtkRenderWindow> renWin =
vtkSmartPointer<vtkRenderWindow>::New();
renWin->AddRenderer( renderer );
//设置窗口的大小
renWin->SetSize( 640, 480 );

//设置窗口的名字

//iren->SetInteractorStyle(0);
iren->Initialize();
iren->Start();
return EXIT_SUCCESS;
}
方法二:使用vtkcommand的方式

}
int main()
{
vtkSmartPointer<vtkCylinderSource> cylinder = vtkSmartPointer<vtkCylinderSource>::New();
//设置圆柱的高度
cylinder->SetHeight( 3.0 );
//设置圆柱的直径
cylinder->SetRadius( 1.0 );
//设置圆柱有多少个侧面
cylinder->SetResolution( 10 );
//===================圆柱的

vtkSmartPointer<vtkActor> cylinderActor =
vtkSmartPointer<vtkActor>::New();
cylinderActor->SetMapper( cylinderMapper );
//设置圆柱的颜色
cylinderActor->GetProperty()->SetColor(1.0, 0.0, 0.0);
//==================渲染器
vtkSmartPointer<vtkRenderer> renderer =vtkSmartPointer<vtkRenderer>::New();
//将圆柱actor添加到渲染器中
renderer->AddActor( cylinderActor );
//设置渲染场景的背景颜色 也就是窗口的颜色
renderer->SetBackground( 1.0, 1.0, 1.0 );
vtkSmartPointer<vtkRenderWindow> renWin =
vtkSmartPointer<vtkRenderWindow>::New();
renWin->AddRenderer( renderer );
//设置窗口的大小
renWin->SetSize( 640, 480 );
renWin->Render();
//设置窗口的名字
renWin->SetWindowName("RenderCylinderAndCone");
//将窗口添加到WindowInterctor中去
vtkSmartPointer<vtkRenderWindowInteractor> iren = vtkSmartPointer<vtkRenderWindowInteractor>::New();
iren->SetRenderWindow(renWin);
vtkSmartPointer<vtkCallbackCommand> mouseCallback =vtkSmartPointer<vtkCallbackCommand>::New();
mouseCallback->SetCallback(MyCallbackFunc); //很重要!!!
iren->AddObserver(vtkCommand::LeftButtonPressEvent, mouseCallback);
//iren->SetInteractorStyle(0); 如果不加上这一句 点一下之后 圆柱体会旋转 之后会打印"You have clicked : " << ++cntPress << " times"
//所以建议加上iren->SetInteractorStyle(0);这一句
iren->Initialize();
iren->Start();
