Reaction: Imaging Vector Fields using Line Integral Convolution

The paper discuss about two main onvolution techniques DDA and LIC,diffrences in approachs, their performance considerations and usage.DDA approximate local vector using straight line whereas LIC relies on a central location from where rendering can be done in diffrent direction.Both the alogrithms have applications in diffrent areas like motion imaging and rendering linear fields. LIC is definately provides better quality but at the cost of performance and speed as LIC is believed to be slower than DDA. Paper is well-organized and supported with examples and images but clear understanding. It also leaves scope for lot of improvements.
