Hi, I am a c++ and c# programmer and I had a few questions on the topic of augmented reality, mainly if there are any tutorials. I was wondering if there were any tutorials for openCV for something like this, http://www.youtube.com/watch?v=PYM4z0WIsIM, or for moving models such as this, http://www.youtube.com/watch?v=I-xITwJrPnk. I was also wondering if there was anything on the topic of markerless augmented reality. Sorry if these questions have already been answered but thank you ask well.
