One of the primary spatial properties of an object, it is the position of an object relative to rotational space. If position describes where an object is placed, orientation describes how the object is placed.
In a literal sense, orientation only figures in when there is rotational movement involved. However, orientation can also describe in the absence of actual rotation - such as left-right in a side-scrolling game, or a 2D sprite's "direction" in an isometric playing field. Questions under the purview of this tag deal with both forms of orientation of entities, for tasks such as determining, storing, or fixing the orientation.
