Reaction: Imaging Vector Fields Using Line Integral Convolution

        This paper talks about Line Integral Convolution, A method for imaging two and three dimensional vector fields.  The LIC Algorithm takes an input image , vector field and generates an output image by filtering the input image along local stream lines defined by the vector field . "The LIC implementation is a module in a data flow system like that found in a number of public domain and commercial products. This implementation allows for rapid exploration of various combinations of operators. The algorithm can be used as a data operator in conjunction with other operators. Specifically, both the texture and the vector field can be preprocessed and combined with post processing on the output image. "
    It talks about DDA covolutions a generalization of traditional line drawing techniques and the spatial convolution algorithms. This summarizes LIC and also its applications.
