CAD-EGS Project: Using CAD Geometrics in EGS4

摘要

The objective of the CAD-EGS project is to provide a way to use a CAD system to create 3D geometries for use within EGS4. In this report, we describe an approach based on an intermediate le, written out by the CAD system, that is read by an EGS4 user code designed for the purpose. A prototype solution was implemented using a commonly used CAD system and the Virtual Reality Modeling Language (VRML) as an intermediate le format. We report results from the prototype, and discuss various problems arising from both the approach and the particular choices made.
