Visual exploration of large and complex 3D steady and unsteady flow fields is critically important in many areas of science and engineering. In this paper, we introduce FlowGraph, a novel compound graph representation that organizes field line clusters and spatiotemporal regions hierarchically for occlusion-free and controllable visual exploration. It works with any seeding strategy as long as the...
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 view-dependent tiny surface passing through...
