Whether there is support OpenGL in QNX?

Kinda? But not really. Checkout the Photon3d Packages.

Whether includes Photon3d in QNX Momentics NC? Please explain that such Mesa, whether it is included in QNX Momentics NC and how all this is bound up with OpenGL?

where can I get this photon3d packages?

QNX 6.5 comes with support for OpenGL ES. The rub is that with OpenGL to do much, you need hardware acceleration. There are three chips supported, all on embedded boards. If you have something simple to do, like the “gears” application then the software support might be enough. In another posting today I mentioned my experience with Mesa, which was not very good.
