In computer graphics, wrapping is the process of limiting a position to an area. A good example of wrapping is wallpaper, a single pattern repeated indefinitely over a wall. Wrapping is used in 3D computer graphics to repeat a texture over a polygon, eliminating the need for large textures or multiple polygons. Wrapping is also used to describe the screen space as a single spacewhere the upper and lower border constitue a continious surface such as the left and right edge. In this manner an object which leaves on the right corner re-appears on the left e.tc. It set the 'render plane' as an endless space.
