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.
