Re: 3D Vision and Linux
Note it might not be that hard to offer support for non-Quadro systems but I haven't looked at in much detail.
On Quadro cards you have the extra din-connector which provides a synchronization signal to the USB transmitter which sends the signals to the glasses. On Windows the glasses also work on Geforce cards. In that I think a signal is generated by hooking in the calls which signal that a frame is ready (wglSwapBuffers in case of OpenGL and Present in case of Direct3D). All that might be needed is someone to figure out what USB commands to send and then a basic GL wrapper like StereoGL might already work.
For professional use, I would still recommend a Quadro since even if this hack I propose works, timing can't be guaranteed in a very reliable way.
