Hi Manish,
I have integrated Chipset and no additional 3d graphics card installed .
Yes, I gathered as much from the error messages that you posted.
Is Software rendering is possible ?
For shadows, you really need Framebuffer Objects to get any acceptable performance. I have seen some integrated chipsets that will make OSG fall back from Framebuffer Objects to pbuffers (as yours does) and then work with pbuffer but more slowly. In your case, it seems that your driver doesn't even support pbuffers.
You might try upgrading your integrated chipset's driver, perhaps that will make it support pbuffers, but I doubt the performance will be acceptable. So you'll probably have to disable shadows when running on that chipset. Note that it's the application's responsibility to detect the hardware or use config files or some other mechanism to disable features that aren't supported / are too slow on the current hardware.
Hope this helps, J-S -- ______________________________________________________ Jean-Sebastien Guay [email protected] http://www.cm-labs.com/ http://whitestar02.webhop.org/ _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
