3D rendering is the process of generating a two-dimensional image from a three-dimensional model using computer software. This technique is widely used in various fields such as architecture, video games, and film to create realistic visuals. The rendering process involves simulating light, materials, and textures to produce lifelike images that can be used for presentations or entertainment. There are different types of rendering techniques, including real-time rendering and offline rendering. Real-time rendering is often used in video games, where images must be generated quickly, while offline rendering is used for high-quality images in movies and animations. Both methods play a crucial role in the visual experience of digital content.
