Reaction: Imaging Vector Fields Using Line Integral Convolution

I was not familiar with vector field and this one was a good but a tuff read for me. Interesting to read about the LIC - Line Integral Convolution for imaging 2D and 3D vector fields. I had studied line drawing algorithm - DDA in undergrad and it was a good refresher here.
A good example of the photograph of flowers processed using the LIC and the blurring effect. Also in the implementation sections it was interesting to know how this LIC technique applies to the maps with the example of wind velocity visualization.
