In scientific visualization, line integral convolution (LIC) is a method to visualize a vector field (such as fluid motion) at high spatial resolutions.[1] The LIC technique was first proposed by Brian Cabral and Leith Casey Leedom in 1993.[2]
In LIC, discrete numerical line integration is performed along the field lines (curves) of the vector field on a uniform grid. The integral operation is a convolution of a filter kernel and an input texture, often white noise.[1] In signal processing, this process is known as a discrete convolution.[3]
