关于多视图

acmiyou

有没有人用OSG 在MFC里头实现 类似附件的多视图的显示.

为什么 我使用CompositeViewer::addView却没法显示 而且会闪烁..

1. void CompositeOSG::addView(HWND hwnd)
   
2. {
   
3.         osgViewer::View* view = new osgViewer::View;
   
4.         viewer->addView(view);
   
5. 
   
6.         view->setSceneData(rootNode.get());
   
7. 
   
8.     // Add a Stats Handler to the viewer
   
9.     view->addEventHandler(new osgViewer::StatsHandler);
   
10.    
    
11.         RECT rect;
    
12.     // Get the current window size
    
13.     ::GetWindowRect(hwnd, &rect);
    
14. 
    
15.     // Init the GraphicsContext Traits
    
16.     osg::ref_ptr<osg::GraphicsContext::Traits> traits = new osg::GraphicsContext::Traits;
    
17. 
    
18.     // Init the Windata Variable that holds the handle for the Window to display OSG in.
    
19.     osg::ref_ptr<osg::Referenced> windata = new osgViewer::GraphicsWindowWin32::WindowData(hwnd);
    
20. 
    
21.     // Setup the traits parameters
    
22.     traits->x = 0;
    
23.     traits->y = 0;
    
24.     traits->width = rect.right - rect.left;
    
25.     traits->height = rect.bottom - rect.top;
    
26.     traits->windowDecoration = false;
    
27.     traits->doubleBuffer = true;
    
28.     traits->sharedContext = 0;
    
29.     traits->setInheritedWindowPixelFormat = true;
    
30.     traits->inheritedWindowData = windata;
    
31. 
    
32.         osg::GraphicsContext* gc = osg::GraphicsContext::createGraphicsContext(traits.get());
    
33. 
    
34.         view->getCamera()->setGraphicsContext(gc);
    
35.         view->getCamera()->setViewport(new osg::Viewport(traits->x, traits->y, traits->width, traits->height));
    
36. 
    
37.         view->getCamera()->setDrawBuffer(GL_BACK);
    
38.         view->getCamera()->setReadBuffer(GL_BACK);
    
39.         view->setCameraManipulator(new osgGA::TrackballManipulator);
    
40. 
    
41. }

我用MFC 分割了两个子视图..结果只会显示背景.没能显示模型.其中的rootNode 初始化为cow.osg..
并且显示的窗口会闪烁..


附加的图是我用OpenGL 画的..>_<

试一试addSlave()，MFC窗口似乎在重绘上存在一些问题
