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

The paper attempts to classify the geometric flow-visualization approaches. The author discusses the challenges in  the field of flow visualization and the classification itself is based on the challenges. The idea of explaining terminologies like  streamline, streakline, paths and surfaces before hand has made the understanding easy and clear. The example of tornado visualization is very interesting. It depicts us how rich a dataset can be and how different visualization techniques can help us perceive multiple dimensions of it.

Overall, this paper has been a great read to get introduction of flow-visualization. Towards the end, the author states that "as the dimensionality of the integral object increases the volume of research decreases" which makes me wonder whether some of the challenges mentioned by the author may not be actually due to lack of computing power.
