Havok Physics

Havok Physics is a physics engine developed by Irish company Havok, used, among others, by Fallout 3 and Fallout: New Vegas. It is designed for computer and video games by allowing interaction between objects or other characters in real-time and by giving objects physics-based qualities in three dimensions. By using dynamical simulation, Havok allows for more lifelike worlds and animation, such as ragdoll physics or intelligence in massive falling objects. The company has also released a Havok Animation. Havok was purchased by Intel in 2007.
