Example "delauney" in osgexamples hasn't helped me. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=41812#41812 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Using your method, I will receive a convex surface, while the convent is necessary to me. -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=41828#41828 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

[osg-users] How to abort rendering
Hi all! I have a problem with rendering. My application always render by demand. When I start camera rotation it render in a draft quality (for better performance), when I stop rotation it start to render in production quality. But in this case application become frozen until end of rendering. Is there any opportunity to abort production rendering if I want to rotate camera again? Or may I render production quality picture in background thread and draw it to screen only when it ready? I mean, my application never should be blocked by rendering. Thank you!
