Ray tracing

Definition

Ray tracing is a rendering technique used in computer graphics to create realistic images by simulating the way light interacts with objects in a virtual environment. This process involves tracing the paths of rays of light as they travel through a scene, reflecting off surfaces and refracting through transparent materials, resulting in highly detailed and visually rich graphics that enhance the artistic quality of video games.
