Would it be possible to have a renderer that renders a cartoon/cell shader style to look soemwhat like the SH3D logo, with black contour lines and cell shaded areas?
I don't think it answers to your question, but if you want, I can send you the "real" model I did for the illustrations of this survey (see also the different versions I did for the survey itself).
You could post-process the SH3D image with a tool such The Gimp. Applying posterization and cartoon filters won't quite look as clean as the posted example, but it will certainly achieve the black shadowing.
