A npr renderer for Wings?

[Dimitri]

Given that Wings is an excellent modeler for presentations of various objects, it would be very useful to have a simple line art (npr) renderer implemented in it. A renderer which will render the hard edges with lines in various thicknesses and keeping the face color information too (producing a contour line around the whole objects also, of course). Such a renderer would add a lot to the app's functionality as a whole. It would upgrade it to a nice illustration producing app… excellent for presenting accurate line drawings.

Does anyone has some idea of how such a thing can be achieved (and if it is possible to be achieved), as to the programming side of the idea?
