我正在用 Metaio 开发 AR 的东西。我有双摄像头，并试图基于 metaio SDK 的 MFC 模板项目制作双 opengl 渲染窗口。http://dev.metaio.com/sdk/documentation/first-app-running-template-on-each-platform/windows/index.html

我尝试制作双窗口并打开不同的相机，例如：

首先，包含MFC窗口和metaio SDK实例的窗口类

class CMyWindow : public CFrameWnd, metaio::IMetaioSDKCallback
{
        CMyWindow();
        ~CMyWindow();

...
        metaio::IMetaioSDKWin32*    m_pMetaioSDK;
        metaio::ISensorsComponent*      m_sensors;
        metaio::GestureHandlerWindows* m_gestureHandler;
}

然后是一个 winApp 类，如：

    class CMyApplication : public CWinApp
{
public:
    virtual BOOL InitInstance();
}

在 InitInstance() 方法中，我组成了两个窗口，例如：

BOOL CMyApplication::InitInstance() 
{
    // we have to call this right at the beginning
    AfxEnableControlContainer();

    // start the main windows, and init ARBrowser
    try
    {
    m_win = new CMyWindow;
        //get cameralist
        metaio::stlcompat::Vector<metaio::Camera> cameraList;
        cameraList = m_win->m_pMetaioSDK->getCameraList();
        //check whether there is two camera.
        assert( cameraList.size() == 2);
        //sync these two camera parameters
        for(int i = 0; i < cameraList.size(); i++)
        {
            metaio::Vector2di res = metaio::Vector2di(RES_WIDTH,RES_HEIGHT);
            cameraList[i].resolution = res;
        }
        //assert(cameraList[0] == cameraList[1]);
        m_win->m_pMetaioSDK->startCamera(cameraList[0]);

        m_pMainWnd = m_win;
        m_pMainWnd->ShowWindow( m_nCmdShow );


        //the other window
        m_win_right = new CMyWindow;
        m_win_right->m_pMetaioSDK->startCamera(cameraList[1]);
        m_pMainWnd = m_win_right;
        m_pMainWnd->ShowWindow( m_nCmdShow );
}catch( std::exception& e )
}

但是，渲染无法正常工作，我看到两个空白窗口。注意到打开了两个摄像头，我发现跟踪状态如果达到模式就会弹出一些东西。我猜是渲染问题。我想检查 metaio 的自定义渲染部分。

有什么建议么？欢迎讨论。
