This contribution is a small MFC sample to learn how to :

    * display a VRML file
    * use OpenGL display lists
    * superimpose wireframe on a flat or smoothly shaded mesh
    * smoothly subdivide a 3D triangular mesh (from Charles Loop)
    * implement mouse interaction (rotation and translation)
    * build a scene graph from a vrml 2.0 file (hand-made and not lex-based)
