Reaction: Imaging Vector Fields Using Line Integral Convolution

The authors present a new method for imaging vector fields using line integral convolution (LIC). A comparison is made between DDA convolution and Line Integral Convolution. The flaw in DDA convolution is that it renders vector fields unevenly, small scaled surfaces loss detail. LIC is an alternative presented on this paper that doesn’t have this flaw, because it uses a different approach for approximating vectors.

The paper is a little complicated and the authors go through all the technique. He discusses its application, implementation, and advantages. Its advantages include: removing the aliasing error, its flexibility (ability to interface with other techniques).
