Douglas Brown has made Tracker better by releasing 3.1 version which has auto tracking function. I emailed him about the possibility of adding it and you know what, he is the man! He added it about 3 months time. cool!
anyway, my friends in school wanted me to conduct PD on the use of this wonderful tool. so i am exploring it again, the other time was Oct-Nov 2009.
I realised to get all the videos in his website, just unzip the http://www.cabrillo.edu/~dbrown/tracker/webstart/tracker_sampler.jar and in the folder video You can find everything, including the parachute_monkey.mov
I will be making a youtube to explain how to use it for video modeling purposes.
