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

This paper mainly talks about the geometry based visualization techniques. It also talks about the side of visualization that deals with motion. Today the field of visualization has advanced to a great extent. Motion and user interaction plays an important role in graphical representation. I think it has been adopted universally. And this is where flow visualization comes into play which has been discussed briefly in this paper. The author also talks about the various challenges faced in flow visualization. I think the biggest challenge now a days is the length and vastness of the data sets. They are so huge that a lot of time is consumed in deciding how to display the available data.

Then the author has discussed various techniques in flow visualization like the direct method, texture based LIC techniques and geometric method which is based on the geometry of objects and last but not the least the feature method.

Another interesting discussion according to me was the example of the tornado using stream surface in comparison to flow volume.
