Description
Parque is an interactive installation with an ecological message where the growth of a forest is determined by the amount of attention it receives. By making upwards movements with their bodies, children can create new trees or grow existing ones. If a tree is left unattended for too long it will shrink and eventually disappear.

    some technical information:
    this was created in c++ using the amazing openframeworks library.movement detection is done using openCv's optical flow and a customopenCV based contour tracker that calculates persistent contouridentification over time. Computer vision is all running on a separatethread to keep things fast.
    Trees and grass are constructed using particles and springs through asimple 2d Verlet physics engine based on this article here: teknikus.dk/tj/gdc2001.htm
