The paper mainly concentrates on the importance of imaging vector fields. The fact that special effects can be produce by using these techniques, it is worth the reading. The examples and the illustrations are so interesting as they try to create special effects on a normal image. Finally their approach boils down to the usage of many techniques that were defined before like texture generation. This paper also discusses about the influence of color, intensity, and direction in scientific visualization. This a very new concept to me, especially the direction.
The description of LIC algorithm, helped me correlating with its practical usage in photo editing software like Photoshop, premiere pro etc. I feel that some more stress should have been give on the influence that this algorithm makes in the medical field, which is a major area where visualization plays a huge role. The growth of this algorithm from DDA algorithm is well mentioned. The drawbacks of the DDA algorithm like loss of accuracy and how the new LIC algorithm solves are described in a very eloquent fashion.
