Calculating shadowing and masking on a rough surface
Heliyon, 2023 Existing research has confirmed that light attenuation has an intrinsic effect on light reflection from rough surfaces. In this study, a technique is developed to solve the shadowing and masking problems of visual representation on a rough surface.
