Questions tagged [terrain]

Terrain, or land relief, is the vertical and horizontal dimension of land surface. Terrain is used as a general term in physical geography, referring to the lie of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. In games, terrain is the "land" or "world" on which the game environment, roads, buildings, vehicles, characters are placed and interact with each other.
