Real-time computer graphics or real-time rendering is the sub-field of computer graphics focused on producing and analyzing images in real time. The term can refer to anything from rendering an application's graphical user interface (GUI) to real-time image analysis, but is most often used in reference to interactive 3D computer graphics, typically using a graphics processing unit (GPU). One example of this concept is a video game that rapidly renders changing 3D environments to produce an illusion of motion.

Computers have been capable of generating 2D images such as simple lines, images and polygons in real time since their invention. However, quickly rendering detailed 3D objects is a daunting task for traditional Von Neumann architecture-based systems. An early workaround to this problem was the use of sprites, 2D images that could imitate 3D graphics.

A media center application, or simply media center, is a type of multimedia and technological convergence software that is designed to be used on a large screen like a television or a projector. They are intended to be controlled by wireless devices such as a remote, game controllers, or a smartphone connected via Wi-Fi.

They usually inherit the combined capabilities of media playback, digital media library organization and aggregation, connection to a media server, music and video playlist creation, music visualizations, live TV playback, media streaming, among others. They then present the content on a 10-foot interface that’s easy to view from a couch or seat, and can have multiple views for browsing media.
