stands for Ray Traced Global Illumination . It is a high-end graphics feature used in modern video games and 3D rendering to simulate how light realistically bounces off surfaces and fills an environment. 🌟 Key Informative Features
Historically, video games relied on "baked" lighting (pre-calculated lightmaps) or simplified screen-space approximations to simulate how light travels. physically simulates the behavior of light rays as they bounce off surfaces within a 3D environment. rtgi 01702
