Line Integral Convolution

Definition

Line Integral Convolution (LIC) is a visualization technique that uses the concept of line integrals to create flow-like images from vector fields. This method takes scalar data and generates textures that represent the underlying flow, allowing for a better understanding of molecular properties and dynamics. By effectively visualizing complex data, LIC helps in interpreting molecular interactions and behaviors, making it a valuable tool in computational chemistry.
