An algorithm of mapping additional scalar value in 2D vector field visualization

Vector field visualization is the most challenging task in the scientific visualization. The algorithm of Line Integral Convolution based on texture image can depict the details of the vector field. To Display multidimensional information on the output image, Some methods such as color mapping, tone mapping are developed to show the direction, orientation and magnitude of the vector field. In this paper, we propose a new method that mapping additional scalar values to the local contrast of the output texture.
