I managed to connect a HD camera to vvvv. I can use the higher video resolution to track the AR-tags now. So I have a much more stable tracking than with the crappy Creative Webcam I used before. Also auto-focus and automatic light adjustments help a lot.

I made this project just for fun because of the open house at our institute this Sunday. There is actually no real use for it. Also I was a bit disappointed by myself. I wanted to do something much cooler (like a AR-Pong), but I guess my vvvv-skills are not as good as I thought.
