Abstract Creating a meaningful and accurate representation of a model designed within a computer aided design system is a major objective of any CAD system developer. Among several methods of representation, the implementation of the wireframe representation, with or without hidden lines removal, using the OpenGL graphics library, presents several challenges that will be presented and discussed within this paper.
