Hello Robert,
Thanks for the hint. But i did not understand the idea of "Current OpenGL context" And the class that you specified requires a context id to instantiate GL2Extensions object. Any more reference into that matter would be of great help Regards Sajjad ---------- Forwarded message ---------- From: Robert Osfield <robert.osfi...@gmail.com> Date: 2009/3/19 Subject: Re: [osg-users] OpenGL EXTENSION support To: OpenSceneGraph Users <osg-users@lists.openscenegraph.org> HI Sajjad, 2009/3/18 ami guru <dosto.wa...@gmail.com> > Is there any class or interface in OSG that can query and print out the > supported extensions within the OpenGL driver ? > There isn't a single method that returns a list of all supported extensions, but there are various methods for getting OpenGL function pointers and checking whether a specific extension is supported. See include/osg/GLExtensions. Please note you'll need to have a valid graphics context, and for the extensions to be initialised before the functions will work as you can only do OpenGL calls from a thread with a valid graphics context. If you have happy do debug work on your app, then enable the verbose debug messages and this will output the lists of supported extensions for you. set the env var OSG_NOTIFY_LEVEL to DEBUG.
