one of my students wants to capture images of people in a museum in order to create a collage of all visitors per day. i wrote a difference tracker for my diploma in 2003 for Processing .68. it did not work anymore with the latest version of Processing. but it took me only half an hour to get it working again.
i want to rewrite it in order to work as java node in x3d and instantviewer for experimenting with people’s silhuettes in 3d..
