tilebaserad

Tile-based, or tilebaserad, describes a design in which the world, scene, or data is built from discrete units called tiles. Tiles are usually uniform in size, such as squares or hexagons, and serve as the basic unit for storage, rendering, collision detection, and navigation. The approach enables modular composition and scalable data management, since larger worlds can be loaded piece by piece.

In video games, tile-based systems lay a grid over the playable world. Designers place tiles to form terrain, buildings, and objects, enabling straightforward level editing and deterministic collision. Movement and pathfinding can operate on the grid, though many titles blend grid layouts with continuous movement. Advantages include simplicity and memory efficiency; drawbacks include limited visual variety and visible seams.

In geographic information systems and web mapping, tiling divides maps into tiles at multiple zoom levels. Tile-based services deliver only the tiles needed for the current view, speeding up panning and reducing bandwidth. Standards include tiled map services and Web Map Tile Service, and the use of XYZ tile schemes. Tiles support offline caching and scalable map delivery.

In computer graphics hardware, tile-based rendering processes the scene in tiles to reduce memory bandwidth and improve cache efficiency. Mobile and embedded GPUs commonly use tile-based renderers, keeping tiles in on-chip memory before composing the final image. This approach trades architectural complexity for energy efficiency.
