Tile graphic
As tiled rendering (also briefly Mz. Tiles called English. Tiles ), a (computer) graphics called, like a mosaic composed gives a much-larger overall picture.
Computer games
The tile technology is often used in computer games because the tiles are easier to calculate and use less memory , which was a sensitive topic until the 1990s of computer technology - until the advent of the 3D accelerator . The use of tiles leads to a certain, also aesthetically comprehensible, computer game form with tile-based landscape structure (English tile-based design ). Today, tile-based landscapes are more traditionally developed because of the special optics or for Flash games that do not use the 3D functions of the graphics card.
Tile-based games
Tiles stand out because they can be seamlessly combined with other tiles. This creates an overall picture from many tiles. The composition and calculation of these tiles to form an overall picture is an internal module of the game, which is called the tile engine . The advantage of the additive arrangement is a large memory saving.
Iso games
In addition to square, draufsichtigen tile designs like many platformers Run - and shoot-'em-up -Play there isometric tiles that give a three-dimensional impression. With them, the playing surface is usually half a height compared to the length and width information, but this is not necessarily specified here. Here the - more complex - calculations are carried out by the Iso engine . Certain operations, such as checking the Z-index, which calculates the spatial depth arrangement and thus the overlap of the tiles, are carried out e.g. B. with ATI graphics cards calculated via a tile. Either the entire tile is discarded or the entire tile is displayed ( clipping ). Traditional tile sizes are 32 × 32 and 64 × 64 pixels .
Even with isometric games, such as simulations and racing games , the tile set is rectangular or square. Individual areas of the tiles are transparent; The superimposed arrangement gives the impression of a seamless inclined surface.
The tile set is saved in a file that records the arrangement of several different tiles to form the final overall picture.
Web design
Tile technology is also used in web design for easier handling or to save the amount of data to be transferred. A common application is background graphics, in which, for reasons of economy or for visual reasons (more uniformity for less distraction), a repeated pattern is created by seamlessly joining a single tile.
Geospatial services
Another application is geodata as very large or high-resolution raster graphics which, as expected, are not needed as a whole at once. These are divided into tiles with the help of geospatial services and the required parts of the overall picture are transmitted and displayed.
Web Map Tile Service is an Open Geospatial Consortium standard for map tile servers.
Archives
Some archives use services such as Zoomify and DFG-Viewer to provide digitized data on their website.
Dezoomify offers a service for displaying the entire image file .
