  abstract = {We present a method to view-dependently control the size of shape
              features depicted in computer-generated line drawings of 3D
              meshes. Our method exhibits good temporal coherence during level
              of detail transitions, and is fast because the calculations are
              carried out entirely on the GPU. The strategy is to pre-compute,
              via a digital geometry processing technique, a sequence of
              filtered versions of the mesh that eliminate shape features at
              progressively larger scales. Each filtered mesh retains the
              original connectivity, providing a direct correspondence between
              meshes. At run-time, the meshes are loaded onto the graphics card
              and a vertex program interpolates curvatures and positions between
              corresponding vertices in adjacent meshes of the sequence. A
              fragment program then renders silhouettes and suggestive contours
              to produce a line drawing for which the size of depicted shape
              features follows a user-specified ``target size''. For example, we
              can depict fine shape features over nearby surfaces, and
              appropriately coarse-scaled features in more distant regions. More
              general levelof-detail policies could be implemented on top of our
              approach by letting the target size vary with scene attributes
              such as depth, image location, or annotations provided by the
              scene designer.},
