Hi all, I'm a real beginner on OSG and I want use it with Qt 4.5 on Win32. I have to export an activeX based on OSG (dev. with VS) on a Qt application. The main purpose it's to display an osg model, and to interactive with it (mouse and keyboard). I already use the adapterWidget class, that I found on example/osgViewerQt source browser. If I just use this class, my application run properly, but, this example use setSceneData() and only this method. I must use setSceneData() and addChild/removeChild methods in my application because I need show/hide some part of osg model when the user will want it.
And if I use this method, I get some graphics bug when I rotate the model with mouse. Indeed, some surfaces disappear to the view, and if I rotate my model it gives an impression of blinking. Also some parts of my model are shown over other parts, while they shouldn't. It's seem to be a zBuffer problem (frustum?). I use setProjectionMatrixAsOrtho instead setProjectionMatrixAsFrustum. If I use frustum my model disappear... With setProjectionMatrixAsOrtho, I can change near & far values, but it doesn't change anything... I will put 3 screen-shots to show in picture my problem: [Image: http://www.monsterup.com/upload/1251290190840.png ] (http://www.monsterup.com) [Image: http://www.monsterup.com/upload/1251290190788.png ] (http://www.monsterup.com) [Image: http://www.monsterup.com/upload/1251290191958.png ] (http://www.monsterup.com) Thank in advance, and sorry for my English level, I'm French :| Cheers, cayou ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=16772#16772 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
