Abstract

AGGRES, a Fortran 77 program for computing a power crust of an aggregate, is discussed. AGGRES takes a finite set of points from the surface of an aggregate, i.e. a three-dimensional object with no holes that contains its center of mass in its interior, and computes a piecewise-linear approximation of the surface of the object called a power crust. AGGRES is based on an algorithm by Amenta, Choi and Kolluri for computing power crusts using power diagrams. Besides a power crust of the object, the program also produces the area of the power crust and the volume of the solid it encloses.
