  abstract = {Drawings made with precise pen strokes accurately reveal the
              geometric forms that give subjects their characteristic shape. We
              present a system for non-photorealistic rendering of precise
              drawing strokes over dense 3D triangle meshes with arbitrary
              topology. During an automatic pre-process, we construct an
              extended version of the edge-buffer data structure to allow the
              calculation of shape measures at each mesh edge, by adapting
              numerical methods used in geomorphology. At runtime, feature edges
              related to shape measures are extracted and rendered as strokes
              with varying thickness and pen marking styles. Stroke thickness is
              automatically adjusted by considering surface curvature. Pen
              marking styles and visual effects of ink distribution are both
              controlled by the user. We demonstrate precise drawing strokes
              over complex meshes revealing a variety of shape
              characteristics.},
