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

This paper starts off by stating some of the challenges that comes with flow visualization. It then moves on and describes the various flow visualization techniques and their respective pros and cons. One criticism that I do have is that the math embedded in this paper is making the paper harder to comprehend. Without a proper 3D or math background, it becomes increasingly difficult to follow the paper as it progresses. While the ample pictures in the paper is interesting and eye catching, it also does not help me understand the content.
