MFC单文档中进行plc点云显示

 1     m_viewer.reset(new pcl::visualization::PCLVisualizer("viewer", false));//初始化pcl::viewer对象    
 2         m_viewer->addCoordinateSystem(); //设置对应的坐标系
 3         m_viewer->setBackgroundColor(0.0, 0.0, 0.0);//设置背景颜色
 4         m_viewer->initCameraParameters();//初始化相机的参数
 5         m_win = m_viewer->getRenderWindow();//将view中的渲染窗口的句柄传递给vtk window
 6         m_iren = vtkRenderWindowInteractor::New(); //初始化vtkwindow交互的对象 
 7         m_viewer->resetCamera();//使点云显示在屏幕中间，并绕中心操

10         CRect rect;
11         GetClientRect(&rect);//实时获取MFC窗口大小
12         m_win->SetSize(rect.right - rect.left, rect.bottom - rect.top);//根据当前窗口的大小设置vtk 窗口的大小
13         //m_viewer->addCoordinateSystem(1);
14         m_win->SetPosition(0, 0);
15         m_win->SetParentId(this->m_hWnd);//设置vtk窗口的句柄
16         //m_iren->SetRenderWindow(m_win);//将vtk交互对象与vtk window绑定 
17         //m_viewer->createInteractor();
18         //m_viewer->setCameraPosition(0, 20, 0, 0, 1, 0);

56         //9.将actor绑定到Render
57         aRenderer->AddActor(skin);
