  abstract = {While many factors contribute to shape perception, psychological
              research indicates that the direction of lines on the surface may
              have an important influence. This is especially the case when
              other techniques (shading, silhouetting) do not present sufficient
              shape information. The psychology literature suggests that lines
              in the principal directions of curvature may communicate surface
              shape better than lines in other directions. Moreover, principal
              directions have the quality of geometric invariance so line
              directions are based on the surface geometry and are viewpoint and
              light source independent, and the lines do not move above over the
              surface during animation unless desired. In this work we describe
              principal direction line drawings which show the flow of curvature
              over the surface. The technique is presented for arbitrary
              surfaces represented by either 3D volume data or a polygonal
              surface mesh....},
