I came upon this idea after setting the Hellboy engine to wireframe rendering (no textures, no flat shading, vector edges only). The picture I saw looked strangely stylish, so I thought to myself "It may be good to have a 3D game made with a vector engine, where each vector represents not the edge of a polygon, but a stroke of the artist''s pencil. I guess it can be more radical than overused cel-shading." Unfortunately, I''m not that good of a coder, so I''m not going to implement it myself. Anyone interested?
