回复：我的vtk日记

请教一下楼楼，我在写三视图的代码，想要在一个window里面同时显示出3D的图像和切片，需要让3D的Actor可以三百六十度旋转而切片只可以点击获取他的表面信息，不能旋转，说白了就是在一个window里面要两种不同的交互方式，想用vtkInteractorStyleUser来实现
class threeViewsInteractorStyle
//:public vtkInteractorStyle
{
public:
vtkImageReslice* pImageReslicex;//切片
vtkImageReslice* pImageReslicey;
vtkImageReslice* pImageReslicez;
float fopac;
vtkRenderWindow *styleRendererWindow;
vtkInteractorStyleUser* interactorStyle;
vtkRenderWindowInteractor* pRenderWindowInteractor;
static threeViewsInteractorStyle *New()
{
return new threeViewsInteractorStyle;
}
threeViewsInteractorStyle();
void MoveEvent();
void OnLeftButtonDown();
};
#include "head.h"
threeViewsInteractorStyle::threeViewsInteractorStyle() :styleRendererWindow(0)
{
interactorStyle = vtkInteractorStyleUser::New();
interactorStyle->AddObserver(vtkCommand::MouseMoveEvent, this, &threeViewsInteractorStyle::MoveEvent);
interactorStyle->AddObserver(vtkCommand::LeftButtonPressEvent, this, &threeViewsInteractorStyle::OnLeftButtonDown);
pRenderWindowInteractor->SetInteractorStyle(interactorStyle);
pRenderWindowInteractor->SetRenderWindow(styleRendererWindow);
}
void threeViewsInteractorStyle::MoveEvent()
{
this->pRenderWindowInteractor->GetPicker()->Pick(
this->pRenderWindowInteractor->GetEventPosition()[0],
this->pRenderWindowInteractor->GetEventPosition()[1],
0,
this->pRenderWindowInteractor->GetRenderWindow()->GetRenderers()->GetFirstRenderer());
double picked[3];
this->pRenderWindowInteractor->GetPicker()->GetPickPosition(picked);
if (picked[0] >= 0 && picked[1] >= 0)
{
vtkSmartPointer<vtkInteractorStyleTrackballCamera> style =
vtkSmartPointer<vtkInteractorStyleTrackballCamera>::New();
pRenderWindowInteractor->SetInteractorStyle(style);
}
else
{
vtkSmartPointer<vtkInteractorStyleUnicam> style =
vtkSmartPointer<vtkInteractorStyleUnicam>::New(); //只有放大和平移的功能
pRenderWindowInteractor->SetInteractorStyle(style);
}
}
void threeViewsInteractorStyle::OnLeftButtonDown()
{
this->pRenderWindowInteractor->GetPicker()->Pick(
this->pRenderWindowInteractor->GetEventPosition()[0],
this->pRenderWindowInteractor->GetEventPosition()[1],
0,
this->pRenderWindowInteractor->GetRenderWindow()->GetRenderers()->GetFirstRenderer());
double picked[3];
this->pRenderWindowInteractor->GetPicker()->GetPickPosition(picked);
cout << picked[0] << "..." << picked[1] << "..." << picked[2] << endl;
if (picked[0] >= 0 && picked[1]>=0)
{
vtkSmartPointer<vtkInteractorStyleTrackballCamera> style =
vtkSmartPointer<vtkInteractorStyleTrackballCamera>::New();
this->pRenderWindowInteractor->SetInteractorStyle(style);
}
else
{
nCount++;
centers[0] += 10;
centers[1] += 10;
centers[2] += 10;
pImageReslicex->SetResliceAxesOrigin(centers);
pImageReslicey->SetResliceAxesOrigin(centers);
pImageReslicez->SetResliceAxesOrigin(centers);
pImageReslicex->Update();
pImageReslicey->Update();
pImageReslicez->Update();
styleRendererWindow->Render();
}
}
上面是代码你有什么建议吗

楼主能加你个好友吗？关于vtk的东西想请教一下
