Reaction: Imaging Vector Fields Using Line Integral Convolution

The paper focuses on Line Integral Convolution, an algorithm for imaging vector fields. The paper gives concise explanation and mathematical model of the algorithm. It also compares the images created by this algorithm with those created by DDA convolution, to depict the effectiveness of the algorithm. The paper explains how integration of periodic motion filters with LIC can produce the motion effect. It also discusses how images can be fine tuned using normalization technique along with LIC. Some of the example images like checkerboard and Flavian Amphitheater under post-processing section are particularly interesting.
