Abstract:
Despite the relative sophistication of modern surface design systems, many graphical renderings of surfaces are rather crude. The paper discusses several possible renderings, including various line drawings methods, realistic and functional shading, and combinations of line drawings and smooth shading. It concludes that a good choice is the superposition of contours or sections on either realistic or Gaussian curvature shading.
