A Graphics Engine is a software component that generates images from 3D models and scenes. It processes data related to geometry, lighting, and textures to create realistic visuals in video games and simulations. Graphics engines are essential for rendering high-quality graphics in real-time, allowing users to experience immersive environments. Popular examples of graphics engines include Unity and Unreal Engine. These engines provide developers with tools and libraries to streamline the creation of graphics, making it easier to design complex scenes and animations. They support various platforms, enabling games to run on consoles, PCs, and mobile devices.
