Vive does not use quad buffer rendering. Roughly speaking, you will need to render a large buffer containing images for both eyes (side-by-side stereo) pre-distorted to match the distortion of the optics in the HMD. The SDK provides the tools for doing this. There is a project integrating the Oculus Rift with OSG already, maybe that you could use as a starting point - the HMDs work very similarly even though the APIs are obviously different. Another option is the OSVR toolkit - their Render Manager supposedly (didn't test it myself) works with Vive and it may be easier to integrate. Regards, J.
