GUAKE CHARACTER OVERLAP WINDOWS

On the 50вЂ“75В MHz PCs of the time, it was common for this pruning step to take many hours to complete on a map, often running overnight if the map design was extremely complex.

Though difficult, this technique was occasionally used by cheaters to create windows in walls, to see normally hidden enemies approaching from behind doors and walls, and resulted in an anti-cheat mechanism used in recent 3D games that calculates a checksum for each file used in the game, to detect players using potentially hacked map files.ДЄ processed map file can have a much lower polygon count than the original unprocessed map, often by 50вЂ“80%. But it is possible to edit a processed map by opening it in a special vertex editor and editing the raw vertex data, or to add or remove individual triangle faces. Instead, the original map editor data with the brushes is retained and used to create new versions of the map. Generally, once a map has been preprocessed, it cannot be re-edited in a normal fashion because the original brushes have been cut into small pieces. The preprocessor then strips away the back faces of the individual brushes, which are outside the game space, leaving only a few polygons that define the outer perimeter of the enclosed game space. The preprocessor is used to locate two types of empty space in the map: the empty space enclosed by brushes where the game will be played and the other empty space outside the brushes that the player will never see. The brushes are placed and oriented to create an enclosed, empty, volumetric space, and when the design is complete, the map is run through the rendering preprocessor. The map editor program uses a number of simple convex 3D geometric objects known as brushes that are sized and rotated to build the environment.

The 3D environment in which the game takes place is referred to as a map, even though it is three-dimensional in nature rather than a flat 2D space. Quake was the first true-3D game to use a special map design system that preprocessed and pre-rendered some elements of the 3D environment, so as to reduce the processing required when playing the game on the 50вЂ“75В MHz CPUs of the time.
