Once the illumination and view angles are determined, LESS calculates the proportions of the four components within each pixel (red rectangle) using ray tracing and subsequently generates the four-component images. In the figure, different colors signify different component, and gap fractions are calculated based on the ratios of the four-component images within a pixel.
