For those of you who are still interested in my free marker-based flash AR tracker, I updated qtrack to v1.0. There were actually only few minor changes, however. 1st, I changed detector code to avoid v0.9 marching squares bug; interesting side effect of this change is that now literally anything that remotely resebles a quad can be used for the marker (like those examples on the right). 2nd, I added requested option to track the marker in NetStream-ed video. 3rd, there is new makePlaneTransform method that should help you with molehill setup (but no molehill demo included for now). 4th, some minor stuff you wouldn’t care about.
On a related note, back in December I promised to make Alternativa3D AR video tutorial for russian xmas, that would include qtrack and other trackers available through FLARManager. I did not finish that video in time, so for this post I uploaded qtrack part only (and chances are that FLARManager part will be only available in text version of tutorial). The video is in russian, but you can try english subtitles. Enjoy:
