Hi,
i want to display my Graphics card OpenGL and GLSL supported version as a
string.
I tried to do this by retrieving the contextID from my view window and the use
the GL2Extensions class.
But whatever i try, the contextID is always 0.
I run a single-threaded app and everything is inside my main loop.
Code:
osg::ref_ptr<osgViewer::Viewer> viewer = new osgViewer::Viewer();
viewer->setSceneData(root);
viewer->setUpViewOnSingleScreen(1);
viewer->setCameraManipulator(new osgGA::TrackballManipulator(),true);
viewer->realize();
unsigned int contextID;
while(!viewer->done())
{
viewer->frame();
osg::GraphicsContext* gc = viewer->getCamera()->getGraphicsContext();
contextID = gc->getState()->getContextID();
}
The GraphicsContext and the State are valid pointers, but the contextID is
always 0.
I'm running OSG 2.9.10 on a Windows 7 64bit, NVIDIA GT 430, latest drivers, two
screens.
What am i doing wrong?
What's the easiest way to just output the OpenGL and GLSL versions?
Thank you!
Cheers,
Stephan[/code]
