You should be able to utilize your GSoC student then. (=

Could probably pull this off using some of the old nevrax code for pixel programs.

I added support for OpenHMD here: https://bitbucket.org/piglop/ryzomcore/commits/2d1c89a19629cc5770157c6218dd89b1babce3c1

When enabled, the player view is forced to "first person" and the rotation is controlled by the Oculus Rift.

I only tried it on Linux but OpenHMD should work on Windows and OS X.

This is very basic. The player model should have a specific rendering (ie. without the head) and there's absolutely nothing about adapting the view to the Oculus display. I tried to implement stereo rendering but I couldn't find a way.

Thanks, piglop! We'll probably need to fix some first person bugs though!

Can you also provide a simple class that (1) returns a CQuat with the orientation, (2) can shift the UCamera to the two neccesary eye rendering points, and (3) provides the necessary data for the shader?

Have asked ThibG as well for a binding with his libvr library, so we can compare the different possibilities.
