Computer graphics

Computer graphics is the field of visual computing, where one utilizes computers both to generate visual images synthetically and to integrate or alter visual and spatial information sampled from the real world. The first major advance in computer graphics was the development of Sketchpad in 1962 by Ivan Sutherland.

This field can be divided into several areas: real-time 3D rendering , computer animation, video capture and video creation rendering, special effects editing , image editing, and modeling . Development in computer graphics was first fueled by academic interests and government sponsorship. However, as real-world applications of computer graphics in broadcast television and movies proved a viable alternative to more traditional special effects and animation techniques, commercial parties have increasingly funded advances in the field. It is often thought that the first feature film to use computer graphics was 2001: A Space Odyssey , which attempted to show how computers would be much more graphical in the future.
