Level of detail

LOD ( English Levels Of Detail - levels of detail ) - a technique in programming three-dimensional graphics , which consists in creating several options for one object with different degrees of detail, which switch depending on the distance from the object from the virtual camera. Another method is to use one basic, “roughly approximate” model and several external add-ons to it. Each subsequent add-on to the main model is supplemented by detail elements in proportion to the add-in number. That is, at the greatest distance the only main model of the object will be displayed. As the latter approaches the player’s camera to the rendering pipeline, subsequent add-ons of parts will be sequentially connected.

The meaning of the reception is that displaying highly detailed objects located at a great distance from the virtual camera is impractical, expensive in computing resources. Using LOD can significantly reduce the requirements for computer resources when displaying graphics on the screen, whether it is rendering or output in real time ^[1] . Using LOD, however, is associated with a widespread bug, in which the low-poly model of the object is displayed in the near future.
