Computer Graphics “graphikos” means 'something written' e.g. Autograph

coined in 1960 by William Fetter, a graphic designer for Boeing

visual images or designs on some surface, such as a wall, canvas, screen, paper, or stone to inform, illustrate, or entertain

William Fetter a Boeing art director,

first person to draw a human figure using a computer. This figure is known as the "Boeing Man

explored the perspective fundamentals of computer animation of a human figure from 1960

was the first to create a human figure as a 3D model.
