Common Geometry Module (CGM): A Generic, Extensible Geometry Interface

摘要

Geometry modeling has in the past five years emerged as a commodity capabilityseveral geometry modeling engines are available which provide largely the same capability, and most high-end CAD systems provide access to their geometry through APIS. However, subtle differences still exist between these modelers, both at the syntax level and in the underlying topological Model. A modeler-independent interface to geometry is critical to solving many of the geometry-based problems which exist in applications like mesh generation. The Common Geometry Module, or CGM, provides such an interface to geometry.
