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。

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, vtkWin32RenderWindowInteractor
vtkWin32RenderWindowInteractor *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Render
inline 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。
