Description: Light direction refers to the angle at which light rays strike a surface. This concept is fundamental in computer graphics, as it influences how objects are perceived in a three-dimensional environment. Light direction affects lighting, shadows, and reflections, which in turn determines the visual appearance of rendered objects. Technically, light direction can be described using vectors that indicate the origin of the light, and it is utilized in lighting algorithms to simulate how light interacts with surfaces. Proper manipulation of light direction allows artists and developers to create more realistic and appealing scenes, enhancing viewer immersion in virtual environments. Additionally, light direction can be static or dynamic, depending on whether the light source moves or remains fixed, adding an extra level of complexity to graphical representation. In summary, light direction is a crucial aspect of computer graphics that directly impacts visual quality and the perception of objects in a three-dimensional space.
