[osg-users] CompositeViewer and osgViewer::ScreenCaptureHandler
I have 4 osgViewer::View's I want to grab and save an image from each. I tried to use osgViewer::ScreenCaptureHandler as part of the composite view but only one view is captured. Then I tried to addEventHandler() to each individual view to test capturing one at a time but it only captured one camera/window with the same view even if the mouse focus is switched from one view to another. In the latter case, I even tried creating 4 separate ScreenCaptureHandler's to addEventHandler() to each osgViewer::View. Can someone suggest how and if osgViewer::ScreenCaptureHandler can be used in this way? thanks very much! -t ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Inherithance from osg::referenced
I never had to create a class that inherits from osg::Referenced but what i gather is that it puts a contract on your class (copy semantics, etc...). It should be pretty much the same for any osg::Referenced derived class except in some exotic cases. So any osg::Referenced class should provide the needed code. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=68098#68098 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Inherithance from osg::referenced
The next best thing to doc is code. If you can't find documentation then you can try to find code that does what you want as examples. In your case it is easy as *a lot* of osg classes inherit from osg::Referenced. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=68097#68097 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
[osg-users] Inherithance from osg::referenced
Hello, I am creating a class that should inherit from osg::Referenced. Is there any guideline document available? I searched for a while and couldn’t find any. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Therefore, all the vertices are read as integers having almost the same value, so the tri-stripper creates a lot of common edges. Try setting LANG=C as a environment variable, or just before reading the file: I have issues because Qt was changing the locale for me. -- Alberto ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
