Euphoria is a game animation engine created by NaturalMotion
is based on a full
simulation of the 3D character, including body, muscles and motor nervous system.
Instead of using limited animations, the characters' actions and
reactions are produced in real-time; they are different every time,
even when replaying the same scene. While it is common for current video
games to use simple ragdolls for animations generated on the fly,
Euphoria uses a more complex method to animate the entire thing of
physically bound objects within the game environment. The engine was to be used in an Indiana Jones game that has since been cancelled. According to its web site, Euphoria runs on the Microsoft Windows, OS X, Linux, PlayStation 3, PlayStation 4, Xbox One, iOS and Android platforms and is compatible with all commercial physics engines.
