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

This paper mainly talk's about Flow Visualization techniques development over last 20 years.It starting author has inform about challenges in flow visualization.I find paper informative and useful for newcomer in field as it provides covers complete details about flow visualization.Paper also contains classifications and terminologies of flow visualization which helps in understanding forthcoming techniques to visualize flow.

All the techniques whether 2D/3D or Surface based/Volumes based were defined very clearly.Paper contained lot of images which were helped to understand and visualize working and output of these techniques(as it was hard to understand just by write-up. Eg. Streamline seeding surface Fig 4).Author has suggested that there are less research on higher dimension and lot of researches are done and are ongoing on seeding and streamline. Paper is very absorbing(interesting) however length of paper impacts reading quality toward later end of paper.
