Abstract

It is noted that computational description of complex geometric shapes can be greatly simplified using so-called combinatorial geometry packages. Such programs have wide application, particularly in ray-tracing and transport problems where the system geometry code can become a sizable fraction of the total program. The authors describe the implementation of one such package, the MORSE-CG, and discuss in detail how it is operated within version 4 of the Electron-Gamma Shower (EGS4) code system of W.R. Nelson et al. (1988). Several geometries representative of common radiation detectors are considered.<>
