A generalized shape descriptor from wire frame models on a CAD/CAM system

Abstract One of the goals of geometric modeling is to enable the construction of a central database for information storage, retrieval, and updating of three-dimensional mechanical components, assemblies, and systems. Because the information is intended for a wide variety of purposes, a geometric model must not only be complete but also be neutral. Therefore, the vital issue is how to best represent the fundamental geometric data. An algorithm is developed for the automated conversion of wire frame data to solid geometric which would give the combined advantages of easy data input and the enormous descriptive power of solid geometric form. How the translated data could be interpreted and coded for manufacturing applications is also explained. The concept of a generalized shape descriptor has been introduced in this context.
