Histogram-based Visualization and Analysis of Vector Fields using Stream Line Projection Plots

  • Field lines in vector fields, e.g. stream lines, path lines, streak lines or time lines, play an important role in the analysis of vector fields. They improve the classification of flow features and its characteristics in particular. Because of the variety of structural information in field lines the effective processing, analysis and visualization play an important role. More effective techniques may contribute to an improved understanding of struc- tural phenomena in a wide range of applications of vector field visualization, such as gaseous flow (e.g. development of cars and aircrafts), design of machines (e.g. turbines), chemistry (e.g. simulation of molecules) and fluid flow in technical or medical applications (e.g. bloodvessel and ocean simulations). This master thesis focuses on the histogram-based visualization and analysis of vec- tor fields using field line projection plots, stream lines in particular. The goal of this work is to develop a hand full of selection criteria to answer specific applica- tion relevant questions about the characteristics and structures of their vector fields. Therefore we present a powerful analysis tool for vector fields or more precisely for their field lines.
