[osg-users] 答复: Blank screen

Hi Robert, This is the code for showing image in MFC window. (I followed the osgviewerMFC example). osg::ref_ptr traits = new osg::GraphicsContext::Traits; traits->x = 0; traits->y = 0; traits->windowDecoration = false; traits->doubleBuffer = true; traits->sharedContext = 0; traits->setInheri

Re: [osg-users] compositeView in multithreaded Win32 MFC MDI application

Well, I have tried a strategy 1 Viewer per 1 ClientWnd. I'm not using Doc/View model. It works pretty well for me. The only thing I have discovered so far: you shouldn't initialize OSG and render thread in WM_CREATE handler. This will cause a crash. Because of this, I have to initialize OSG and

Re: [osg-users] Aborting frames that take too long

I did some more research into what's going on and, on a hunch, changed my threading model from ThreadPerCamera (default for my PC) to SingleThreaded and ThreadPerContext. I found that setAbortRenderPtr does indeed lock up the camera thread on ThreadPerCamera, however it seems to behave 100% corr

Hi all, I am trying to output my volume image on full screen with MFC by changing GraphicsContext in camera. First I get GraphicsContext from camera and then close it. Then I created a new GraphicsContext with setting screen number and size of full screen and then set it to camera. It work

Hi Nguyen, It's about 15 months since I wrote the experiment V8 and Python plugins. This plugins were written as a initial test how easy it would be to support JavaScript and Python respectively - they simply link to the 3rd party library and run the script but there isn't any OSG scene graph inte
