Spatial data commonly consists of a geographic element and related attribute data; therefore spatial ETL transformations are often described as being either " geometric transformations "-transformation of the geographic element-or " attribute transformations "-transformations of the related attribute data.

Primitive vertex attribute data may be inserted frame by frame into a command buffer by a rendering API . This involves significant bandwidth and processor time ( especially if the graphics processing unit is on a separate bus ), but may be advantageous for data generated dynamically by the CPU . It is less common since the advent of increasingly versatile shaders, with which a graphics processing unit may generate increasingly complex effects without the need for CPU intervention.
