Reaction: Imaging Vector Fields Using Line Integral Convolution

The authors introduce this paper with the usefulness of imaging vector fields. They discuss about the techniques that can be combined to produce special effects in the images. Through the first part of the paper, the authors have discussed about the vector visualization algorithms and their features. The authors discuss about spatial resolution technique, vector field technique, reaction diffusion technique and three dimensional texture generation techniques. But the authors cite the need for an algorithm that can image dense vector fields independent of both predefined sampling placement constraints and texture generation techniques and should work in two and three dimensions.

The Line Integral Convolution algorithm described in this paper is quite interesting for the post processing in images. I particularly enjoyed reading through the implementation and application of the same. The examples illustrated for the post processing techniques and creating a three dimensional effect on the image was quite interesting. After the discussion, I was left wondering about the actual usage of this technique. There is quite a possibility of the effect causing some disturbance in sight when such images are used over a larger display. Again as mentioned, the accuracy of this algorithm is also an area that needs further clarification and research. Also considering the current panoramic technology, the relevance of this algorithm is again a question, in my opinion.
