  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."
