Check out a couple of short, 13-frame MPEG movies:
Per-Cell Cones Movie and
Depth-Averaged Cones Movie. (Note:
you may want to tweak your Mailcap file so that mpeg_play will
loop explicitly, since these movie loops are so short.
Backwards streamlines computed from a virtual well placed at what
looks like an oil producing area. A radius of about "1200" (in the local
coordinate system) spreads the seed points out around the well. The streamlines
are depth-colorized, and some effort in tweaking renderer parameters was
needed (depth cueing and adjusting of the front/rear clipping planes) to
effectively "hide" data which is "far away".
