Reaction : Over Two Decades of Integration-Based, Geometric Flow Visualization

In this paper, geometry-based flow visualization techniques form the focus of discussion. The author makes a very good observation that although technology is moving forward there is a gap between data sets and visualization. A key observation is the fact that although there are a lot visualization tools, there is no once such tool that gives good results to the various flowing visualization. Also there is considerable focus on 2D and 3D unsteady flows can be a problem to focus in future.
