  abstract = {The shape of a complex surface can often be conveyed with just ``a
              few good lines''. Line rendering is particularly beneficial when
              visualizing implicit surfaces, as the cost of extracting
              sufficiently accurate iso-surfaces can be very high. We are
              exploring the use of low-resolution iso-surface meshes generated
              in real-time [Schmidt et al. 2005] to interactively render
              implicit surfaces in a pen-and-ink style. Our approach utilizes
              silhouettes and feature contours extracted from coarse meshes as
              an initial approximation to the actual surface contours. These
              coarse feature lines are then iteratively refined using the
              implicit functions, producing smooth and highly interactive
              results.},
