This article explains how to generate resolution independent versions of 3D meshes rendered by OpenGL/MFC programs, i.e. how to export the rendering results to vectorial formats such as encapsulated postscript (EPS) and Windows enhanced metafile (EMF) formats. The main goal consists of being able to
