Rendering is a general term for methods that display a realistic-looking three-dimensional solid object on a two-dimensional output device (normally screen or paper). Perhaps the simplest way to render an object is to display its surface as a wireframe. The next step in rendering is to display, as a wireframe, only those parts of the surface that would be visible in real life. More realistic rendering is achieved by shading–computing the amount and color of the light emitted from every point of the surface. Complete realism may be achieved by simulating surface texture, reflections from neighboring surfaces, and shadows cast by all the objects in the scene.
