The first computer graphics were the output of text and numbers on electronic displays, though computer graphics today typically refers to creating images and not text. This field can be divided into two general areas: real-time rendering, and non real-time rendering. Development in computer graphics was first fueled by academic interests and government sponsorship. However, as real-world applications of computer graphics(CG) 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. However, all the "computer graphic" effects in that film were hand-drawn animation, and the special effects sequences were produced entirely with conventional optical and model effects.
Perhaps the first use of computer graphics specifically to illustrate computer graphics was in Futureworld[?] (1976), which included an animation of a human face and hand - produced by Ed Catmull[?] and Fred Parke[?] at the University of Utah.
With the birth of the workstation computers (like LISP machines, paintbox[?] computers and Silicon Graphics[?] workstations) came the 3D computer graphics, based on vector representations of virtual objects. (See this article.)
Some major advances in 3D computer graphics have been:
