Parque is an interactive installation with an ecological message wherethe growth of a forest is determined by the amount of attention itreceives.
By making upwards movements with their bodies, children can create newtrees or grow existing ones. If a tree is left unattended for too longit will shrink and eventually disappear.
It intends to show children a direct relation between human action and the preservation of natural environments.
This installation was commissioned by the city of Almada to be part ofa permanent exhibition at Parque da Paz, a beautiful park in Almadathat now celebrates its 10th birthday.

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
