| | Suggestive contours |
 | | The picture in the center renders occluding contours, and shows that contours, on their own, can be quite limited in the information they convey about shape. |
 | | While this implementation of suggestive contours can be used to make (what we think are) pretty pictures, as illustrated in our suggestive contour gallery, it can also be used to make some not-so-pretty ones. |
 | | Finding suggestive contours requires the computation of first, second, and third "derivatives" of the surface geometry, and this computation is very sensitive to noise and under-tessellation. |
