To move freely you must be deeply rooted. Bella Lewitsky (1916-)
After stream arrows for stream surfaces and a visualization
technique based on Poincaré maps, a local visualization
technique focusing on critical point is presented .
Critical points, i.e., system states where there is no evolution
at all, usually are properties investigated in the very first
place. Examining the neighborhood of the critical points often
tells quite important principal characteristics about the entire
system behavior. Thus, it's logical to come up with visualization
techniques focusing on that kind of information.
