3D graphics are digital models generated in the circuits of a computer. The technique, first produced in research laboratories for the purposes of visualising space for flight simulators, is now widely used in the fields of science, medicine, industry, entertainment and art. Be they precisely recorded and modelled renderings of real objects and spaces, results of mathematical computations or the product of a computer artist’s imagination, such pictures offer us novel virtual worlds that can be manipulated and with which we can interact.
