This page assembles some results (five images and seven animation sequences) of a project at our department in spring, 1996. The images are provided in JPEG format and the animation sequences are given as short MPEG video clips. A video compromising all the MPEG clips has been produced as well. This work has been done in the scope of our research topic ``Visualization of Complex Dynamical Systems''.

The first image (plate 1, ~52KB) shows a streamsurface of a dynamical system. Our streamarrows texture was applied to this streamsurface.
The second image (plate 2, ~82KB) shows the same streamsurface. This image was generated by applying a particular spot noise texture to emphasize the inner-streamsurface evolution induced by the dynamical system. A hash-shaped spot (see the image at the right side) was used to generate the texture (~31KB).
The third image (plate 3, ~93KB) shows two streamsurfaces. The one to the left is the same surface as in figure 1 and 2, the other streamsurface was generated by letting the time run backwards instead of forwards. This image was taken from animation sequence 3b (see below) and changed just a little bit.
The fourth image (plate 4, ~88KB) shows the same configuration as figure 3, but the plane ``cutting away'' parts of the visual representation has been moved deeper into the model. This images was also taken from animation sequence 3b (see below) and changed just slightly.
The fifth image (plate 5, ~28KB) shows the AVS net that was used to render animation sequence 2a (see below).

The animation sequence 1a (~1.3MB) shows the streamsurface show in all of the images being constructed.
The animation sequence 1b (~110KB) show the streamarrows texture smoothly applied.
The animation sequence 1c (~350KB) should be cycled and shows the streamarrows texture being animated (moving along the streamsurface).
The animation sequence 2a (~1.4MB) shows the same streamsurface as in the previous clips, but from another viewpoint. Additionally the inverse system is represented by another streamsurface being constructed.
The animation sequence 2b (~450KB) was generated by applying a streamarrows texture to the second streamsurface as well and animating both. This sequenced can be cycled.
The animation sequence 3a (~330KB) uses again another viewpoint. Now both rolls of a streamsurface are viewed from the side. This clip may be cycled as well.
The animation sequence 3b (~2MB) was generated by moving a plane slowly through the model cutting parts ``above'' the plane away by making these parts semi-transparent.
