A computer geometry model of the ZSU-23-4 (a quad 23-mm self-propelled antiaircraft gun) was obtained in Ballistic Research Laboratory-Computer Aided Design (BRL-CAD), a combinatorial solid geometry-based modeling system. The BRL-CAD file served as input to a software package (ECLECTIC) that generated a flat, triangular, all-metal facet representation of the ZSU exterior structure, containing approximately 78,000 facets. The facet model served as...
