For their diploma in Software Engineering at the Dresden University of Technology Pedro and Karsten researched methods of animating a 3D tree model in realtime, especially in the wind. Therefore they developed this program which has several options to simulate different conditions. Very interesting is the possibility to produce "local wind". This is wind force that influences only certain regions of the tree. It can be used in computer games, for instance to display the shock wave of nearby explopsions.
