Vector field visualization with characteristic lines, such as streamlines, is based on particle tracing and, therefore, depends on an appropriate choice for particle starting points. In this paper, two approaches for this issue of seed point positioning are described: first, a dense texture-based representation that can be implemented on GPUs; second, a topology-based approach.
