Alpha Shapes

Creators: Ping Fu, Gilles Bourhis, Robert Schade, Herbert Edelsbrunner, Ulrike Axen, Robin Bargar, Insook Choi

Description: Visualization of alpha shapes - a generalization of convex hulls.

Button 2 rotates the shape, based on the direction of the wand.
Button 3 explodes the shape. If the wand is pointed up, the pieces move apart; if it is pointed down, the pieces move back together.
