Description: Light refraction is the phenomenon that occurs when light changes direction as it passes from one medium to another with different optical density. This change in direction is due to the variation in the speed of light in different materials, causing light rays to bend. Refraction is a fundamental principle in optics and can be observed in everyday situations, such as when a pencil appears to bend when submerged in water. In 3D rendering, refraction is used to simulate how light interacts with transparent or translucent materials, such as glass or water, creating realistic visual effects. The correct implementation of refraction in computer graphics is crucial for achieving images that mimic reality, as it affects the appearance of objects and their surroundings. Rendering algorithms, such as ray tracing, use mathematical models to calculate how light refracts when passing through different surfaces, allowing digital artists to create scenes with a high degree of realism. Refraction influences the perception of space and depth in virtual environments, making the user experience more immersive.
