三维体渲染颜色不透明度调整

先上图片：

再上代码：

vtkSmartPointer< vtkRenderer > aRenderder = vtkSmartPointer< vtkRenderer >::New();
	vtkSmartPointer< vtkRenderWindow > aRenWin = vtkSmartPointer< vtkRenderWindow >::New();
	vtkSmartPointer< vtkRenderWindowInteractor > aInteractor = vtkSmartPointer< vtkRenderWindowInteractor >::New();
	 
	aRenWin->AddRenderer(aRenderder);
	aInteractor->SetRenderWindow(aRenWin);
	vtkSmartPointer mouseCallback = vtkSmartPointer::New();
	aInteractor->AddObserver(vtkCommand::LeftButtonPressEvent, mouseCallback);
	mouseCallback->SetClientData(NULL);

问题： 怎么把vtk的窗口与QT结合。就是让第一个窗口Win32OpenGL    #1显示在一个QT控件中？
