Real-time computer graphics

Real-time computer graphics is the subfield of computer graphics focused on producing and analyzing images in real time. The term can refer to anything from rendering an application's GUI to rendering a complex 3D scene for a video game, but it is most often used in reference to real-time 3D computer graphics, as the fields of real-time image processing and image analysis are typically referred to specifically, and with modern computers, 2D rendering is trivial to perform in real time.
