Hi Michele, The OSG manages extensions on a per StateAttribute level, with each subclassing needing extensions maintaining its own Extension structure pre graphics context. Note each graphics context can have different extensions support, although this is not the usual setup, it worth being aware of. Once the extension structure is set up (done the first time that attribute is called by the graphics context) you can querry the extension supported from any thread.
You can also the osg::isGLExtensionSupport(char*) method from a thread with graphics context current if you have a specific extension you want to check. Given the above GLEW won't actually give you anything extra. Robert.
