VTK：VTK嵌入MFC成功

          VTK作为医学显示库，得到较多使用。作为较为上层的设计，对OpenGL进行了封装，并且有Windows、Linux、安卓等开发版本，可移植性较强。

          不过VES暂时没有编译成功。

          以下是嵌入MFC-IDC代码，有个缺陷，暂时没能修改。

代码：

showPointsInVtk(short* &depthImage, int HeightDepth, int WidthDepth,int IDCX){//double arr[3];vtkPoints * points = vtkPoints::New();int n = 0; int idx = 0; int Length = 3 * HeightDepth*WidthDepth;//首先读取点云数据到点表points同时指定点对应的id:for (int i = 0; i < HeightDepth; ++i){int LastPixel = i* WidthDepth;for (int j = 0; j < WidthDepth; ++j){int y = depthImage[3 * (j + LastPixel)];int x = depthImage[3 * (j + LastPixel) +1];int z = depthImage[3 * (j + LastPixel) +2];points->InsertPoint(n, x, y, z);n++;}}printf("%d\n", n);vtkPolyVertex * polyvertex = vtkPolyVertex::New();polyvertex->GetPointIds()->SetNumberOfIds(n);        int i = 0; //建立拓扑关系        for (i = 0; i < n; i++){polyvertex->GetPointIds()->SetId(i, i);}vtkUnstructuredGrid * grid = vtkUnstructuredGrid::New();grid->SetPoints(points);grid->InsertNextCell(polyvertex->GetCellType(),polyvertex->GetPointIds());vtkDataSetMapper *map1 = vtkDataSetMapper::New();map1->SetInputData(grid);vtkActor *actor1 = vtkActor::New();actor1->SetMapper(map1);actor1->GetProperty()->SetColor(0.194, 0.562, 0.75);vtkRenderer *ren = vtkRenderer::New();ren->AddActor(actor1);ren->SetBackground(0, 0, 0);//renWin和iren分别是vtkWin32OpenGLRenderWindow, vtkWin32RenderWindowInteractorvtkWin32RenderWindowInteractor        *iren = vtkWin32RenderWindowInteractor::New();vtkWin32OpenGLRenderWindow             *win = vtkWin32OpenGLRenderWindow::New();vtkInteractorStyleTrackballCamera    *style = vtkInteractorStyleTrackballCamera::New();win->Clean();win->SetSize(480, 360);win->BordersOn();win->AddRenderer(ren);iren->SetRenderWindow(win);iren->SetInteractorStyle(style);//搭上一个显示用的MFC窗口框架。         CWnd *viewer_Wnd;        viewer_Wnd = this->GetDlgItem(IDCX);            HWND hWnd = (HWND)viewer_Wnd->m_hWnd;         HWND hParent = ::GetParent(hWnd);        //::ShowWindow(hParent, SW_HIDE);        ::ShowWindow(hParent, 1);        win->SetParentId(this->m_hWnd);        iren->Start();        map1->Delete();        grid->Delete();       actor1->Delete();        polyvertex->Delete();        ren->Delete();        win->Delete();        iren->Delete();        return 1;}

显示效果：

 

 注意事项：

使用

iren->Start();

导致renter不能更行，修改为以下代码可以完成动态更新：

把 render和win放在初始对话框初始化，其他代码修改为：

this->win->Render();

//在 对话框初始化时初始化Renderinline int Ciisu2vrMfcsDlg::showPointsInVtkG(short* &depthImage, int HeightDepth, int WidthDepth, int IDCX){//double arr[3];vtkPoints * points = vtkPoints::New();int n = 0; int idx = 0; int Length = 3 * HeightDepth*WidthDepth;//首先读取点云数据到点表points同时指定点对应的id:for (int i = 0; i < HeightDepth; ++i){int LastPixel = i* WidthDepth;for (int j = 0; j < WidthDepth; ++j){int y = depthImage[3 * (j + LastPixel)];int x = depthImage[3 * (j + LastPixel) + 1];int z = depthImage[3 * (j + LastPixel) + 2];//这里压缩四倍是比较好的方法//int z = (depthImage[(j + LastPixel)]) ;points->InsertPoint(n, x, y, z);n++;}}vtkPolyVertex * polyvertex = vtkPolyVertex::New();polyvertex->GetPointIds()->SetNumberOfIds(n);int i = 0;//建立拓扑关系for (i = 0; i < n; i++){polyvertex->GetPointIds()->SetId(i, i);}vtkUnstructuredGrid * grid = vtkUnstructuredGrid::New();grid->SetPoints(points);grid->InsertNextCell(polyvertex->GetCellType(),polyvertex->GetPointIds() );vtkDataSetMapper *map = vtkDataSetMapper::New();map->SetInputData(grid);vtkActor *actorG = vtkActor::New();actorG->SetMapper(map);actorG->GetProperty()->SetColor(0.194, 0.562, 0.75);vtkRenderer *ren = vtkRenderer::New();ren->AddActor(actorG);ren->SetBackground(0.13, 0.40, 0.15);this->win->AddRenderer(ren);this->win->Render();//自己写一个重载-更新函数！map->Delete();grid->Delete();actorG->Delete();polyvertex->Delete();return 1;}

后记：

        效果还不错，就是和OpenCV结合时有点麻烦，命名空间冲突。
