Graphics technology, such as 3D rendering engines and game engines, is used to create visual simulations in video games. These technologies facilitate the rendering of complex graphics, animations, and physics interactions that bring virtual worlds to life. Popular graphics engines like Unity or Unreal Engine provide developers with tools and frameworks to design visually impressive and immersive experiences. Advanced techniques such as ray tracing and shading methods enhance realism by simulating light interactions in a virtual environment. Ultimately, graphics technology enables game creators to produce high-quality visuals that engage players and enhance overall gameplay experience.
