True stereoscopic quad buffering in XNA

We are trying to make 3D stereoscopy work within XNA for Windows PC Games using NVidia 3D Vision, we really have no idea how this would be achieved and are just now skimming through the XNA documentation, while we found some examples for anaglyph 3D, we were wondering if there was any way to make it work with the Active glasses that NVidia bundles with its 3D Vision package.

We would also love to hear any alternatives as to how we could make this work on Xbox360, without the glasses of course.

Thanks in advance :3

Solution

To enable quad-buffering, in XNA 3.1, what you are looking for is (MSDN):

PresentationParameters.BackBufferCount = 3;

You will also want to have VSync turned on.

You may find you need to either not use the Game class or use it "unusually". If you find yourself having to write your own draw loop, the function you want is GraphicsDevice.Present.

Now the bad news is that according to the XNA 4.0 documentation for PresentationParameters, that feature has been moved or removed. But 4.0 is still in beta, so the API and documentation are not final yet.
