  abstract =   "This paper presents several strategies to interactively
               explore 3D flow. Based on a fast illuminated streamlines
               algorithm, standard graphics hardware is sufficient to gain
               interactive rendering rates.  Our approach does not require
               the user to have any prior knowledge of flow features. After
               the streamlines are computed in a short preprocessing time,
               the user can interactively change appearance and density of
               the streamlines to further explore the flow. Most important
               flow features like velocity or pressure not only can be
               mapped to all available streamline appearance properties
               like streamline width, material, opacity, but also to
               streamline density.  To improve spatial perception of the 3D
               flow we apply techniques based on animation, depth cueing,
               and halos along a streamline if it is crossed by another
               streamline in the foreground. Finally, we make intense use
               of focus+context methods like magic volumes, region of
               interest driven streamline placing, and spotlights to solve
               the occlusion                  problem.",
