3.1. Colored Streamline

This visualization method is an enhancement of a standart visualization method, the so called streamlines. Streamlines are generated by selecting a startpoint somewhere in the phasespace, and then inegrating from there with some sort of integration (e.g. Euler, Runge Kutta, ...) over a given time (user defined) or until a given spatial length (user defined) is reached.

With this new approach, the colored Streamlines, more information than only the way of the integration can be visualized. By adding the possibility to use a colormap and some transferfunction to assign every step of the integration of the streamline a color, several different attributes can be visualized together with the streamline. One possibility is to encode the speed of the integrated streamline by assigning low speed a blue color, and the highest speed a red color, for exampel. For more attribute mapping techniques see the examples below, or have a look at the ColorMapping Section in the Tools part of this documentation.

In the two pictures above, as well as in the one below, the velocity of the streamline is color coded as described above. For other mappings see at the earlier mentioned ColorMapping section of this document.
