Since we want to perform Augmented Reality, we will need to have another technique to overlay the virtual content over the video view. There are different ways to do that, and the best method is certainly to use a common view, which will integrate the virtual and video content nicely. A powerful technique is to use a managed 3D graphics library based on a scenegraph model.
