Line Integral Convolution. Line integral convolution is a texture based technique for visualizing vector fields and has the advantage of being able to visualize large and detailed vector fields in a reasonable display area. Line integral convolution involves selectively blurring a reference image as a function of the vector field to be displayed. The reference image can be anything, but to make the results clearer, is usually an spatially uncorrelated image (e.g., a noise image). The resulting image appears stretched and squished along the directions of the distorting vector field streamlines, visualizing the flow with a minimum of display resolution. Vortices, sources, sinks and other discontinuities are clear shown in the resulting image, and the viewer can get an immediate grasp of the flow fields major events. MMI
