Version 1.0 of the Havok SDK was unveiled at the Game Developers Conference (GDC) in 2000. The Havok SDK is multi-platform by nature and is always updated to run on the majority of the latest platforms. Licensees are given access to most of the C/C++ source-code, giving them the freedom to customize the engine's features, or port it to different platforms although some libraries are only provided in binary format. In March 2011, Havok showed off a version of the Havok physics engine designed for use with the Sony Xperia Play, or more specifically, Android 2.3<ref>[https://www.engadget.com/2011/03/05/havok-physics-engine-comes-to-android-2-3-demoed-on-xperia-play/ Havok physics engine comes to Android 2.3, demoed on Xperia Play]</ref>.

Havok is a middleware software suite developed by the Irish company Havok. Havok provides a physics engine component and related functions to video games.

On September 14, 2007, Intel announced it had signed a definitive agreement to acquire Havok Inc.[1] In 2008, Havok was honored at the 59th Annual Technology & Engineering Emmy Awards for advancing the development of physics engines in electronic entertainment. On October 2, 2015, Microsoft announced it had acquired Havok.[2]


Products

The Havok middleware suite consists of the following modules:[3]

  • Havok Physics: It is designed primarily for video games, and allows for real-time collision and dynamics of rigid bodies in three dimensions. It provides multiple types of dynamic constraints between rigid bodies (e.g. for ragdoll physics), and has a highly optimized collision detection library. By using dynamical simulation, Havok Physics allows for more realistic virtual worlds in games. The company was developing a specialized version of Havok Physics called Havok FX that made use of ATI and NVIDIA GPUs for physics simulations;[4] however, the goal of GPU acceleration did not materialize until several years later.[5]
  • Havok AI: In 2009, Havok released Havok AI, which provides advanced pathfinding capabilities for games. Havok AI provides navigation mesh generation, pathfinding and path following for video game environments.
  • Havok Cloth: Released in 2008, Havok Cloth deals with efficient simulation of character garments and soft body dynamics.
  • Havok Destruction: Also released in 2008, Havok Destruction provides tools for creation of destructible and deformable rigid body environments.
  • Havok Animation Studio (discontinued): Havok Animation Studio is formally known as Havok Behavior and Havok Animation. Havok Behavior is a runtime SDK for controlling game character animation at a high level using finite state machines. Havok Animation provides efficient playback and compression of character animations in games, and features such as inverse kinematics.
  • Havok Script (discontinued): Havok Script is a Lua-compatible virtual machine designed for video game development. It is shipped as part of the Havok Script Studio.
  • Havok Vision Engine (discontinued): On August 8, 2011, Havok announced their acquisition of German game engine development company Trinigy and their Vision Engine and toolset.
