  abstract  = {One of the reasons that topological methods have a limited popularity
              for the visualization of complex 3D flow fields is the fact that
              their topological structures contain a number of separating stream
              surfaces. Since these stream surfaces tend to hide each other as
              well as other topological features, for complex 3D topologies the
              visualizations become cluttered and hardly interpretable. One solution
              of this problem is the recently introduced concept of saddle connectors
              which treats separation surfaces emanating from critical points.
              In this paper we extend this concept to separation surfaces starting
              from boundary switch curves. This way we obtain a number of particular
              stream lines called boundary switch connectors. They connect either
              two boundary switch curves or a boundary switch curve with a saddle.
              We discuss properties and computational issues of boundary switch
              connectors and apply them to topologically complex flow data.},
