Reaction: Imaging vector fields using line integral convolution

A vector field can be thought of as a vector to each point in a plane. This understanding of the vector field was not apparent while reading the paper. The paper talks about mapping these vector fields into two and three dimentional space using Line Integral Convolution. One thing to notice is that the paper talks about deriving the method of line integral convolution from DDA convolution which is informative. The pictures depicting the variation of Local streamline L are very informative.
