Euphoria is a game engine animation software developed and created by NaturalMotion based on Dynamic Motion Synthesis, NaturalMotion's proprietary technology for animating 3D characters on-the-fly "based on a full simulation of the 3D character, including body, muscles and motor nervous system" on next-generation consoles. It is most well known in its incorporation into the Rockstar Advanced Game Engine (RAGE), which Grand Theft Auto IV and Red Dead Redemption runs on, for its use in advanced character simulation animation and ragdoll physics.
The software allows characters and even players to perform enhanced animated movements more naturally and interactively by utilizing "on-the-fly" programming animation, combining artificial intelligence, biomechanics and physics. Euphoria covers nearly all in-game animated behaviors, including firearm usage, hand-to-hand combat, jumps and climbs, recoveries and interactions with in-world objects.
In addition to enhanced animation cycles, Euphoria is also designed to perform more life-like animations and an underlying sense of self-preservation giving each character unprecedented interactivity and realism.
Euphoria is optimized to run on next-generation consoles such as PlayStation 3, Xbox 360, and PC and is powering on most Rockstar Games such as Grand Theft Auto IV, Red Dead Redemption and Max Payne 3.
