Parallel streamline placement is still an open problem in flow visualization. In this paper, we propose an innovative method to place streamlines in parallel for 2D flow fields. This method is based on our proposed concept of local tracing areas (LTAs). An LTA is defined as a subdomain enclosed by streamlines and/or field borders, where the tracing of(More)
Illumination is an important way to provide cues for spatial perception, and special lighting models are proposed to illuminate lines in 3D space. To achieve better spatial perception of streamlines, a new streamline illumination method is proposed in this paper, which is based on the fact that a streamline is a sample of a stream surface. In our method, a(More)
In order to emphasize features in flow textures while preserving the orientation of flows in 2D fields, a new method to generate flow textures with non-uniform streamlets is proposed in this paper. In the method, a control grid is built and divided into different regions that reflect the complexity of the underlying flow field. The resulting regions are(More)
