POLYBRICK: Adventures in the Domain of Parallelepipeds

Abstract

A collection of programs tries to recognize, which one more successfully than its predecessor, 3-dimensional parallelepipeds (solids limited by 6 planes, parallel two-by-two), using as data 2-dimensional idealized projections. Special attention is given to the last of those programs; the method used is discussed in some detail and, in the light of its success and failures, a more general one is proposed.
