Parametric Animation

Parametric animation is an animation technique used in computer software, such as in computer games, that blends two or more separate animations together to form a new animation. This new animation is constructed in real-time by the game engine, and is not stored in a separate file like a regular animation. The technique was first used in an early build of the Half-Life mod, Team Fortress 2, and it not only heavily reduces artist workload during game development, it provides for much smoother animation as well.
