<<Here's one I thought of today: how about an .APX that at render time compares the current camera view with the object, and renders the object as-is but also renders a new object which basically "outlines" the 3D object as seen from the current view, thus providing a 2D-like cartoon look?>> Looking at some Disney characters right now I see that they are not only outlined but all the inner sections( lips, checks, etc ) are also given a line. So while it may appear at first that you could just do an edge-finding search, it is more complex that that since you don't want to display all the edges only particular ones. I have worked out an algorithm to create such lines for any given object, even to produce smoothed outline edges from faceted objects including the silhouette which is necessary for cartoon characters. Given that the routine would output an image, I think this would be best coded as an .IXP that works on the objects in the scene to produce the "outlined image".
