Decomposing Three-Dimensional Shapes into Self-supporting, Discrete-Element Assemblies

This study investigates a computational design approach to generate volumetric decompositions of given, arbitrary, three-dimensional shapes into self supporting, discrete-element assemblies. These assemblies are structures formed by individual units that remain in equilibrium solely as a result of compressive and frictional contact forces between the elements. This paper presents a prototypical implementation of a decomposition tool into a CAD software, focusing on user-controlled design to generate such assemblies. The implementation provides an interactive design environment including real time visual feedback, in which the design space of self-supporting block assemblies can be explored and expanded. Some surprising results of such explorations are included and discussed.
