Typhoon is an unofficial open source implementation of the Tempest math library circa 2010.
The Tempest math library is a collection of 3D-math-centric classes and functions created by the talented folks at Blizzard Entertainment for use in their games.
This project attempts to provide a version of Tempest compatible with the version used in the final release build of World of Warcraft: Wrath of the Lich King in 2010: 3.3.5a (12340).
In the spirit of documenting what is presumed to have existed at the time, this project makes every attempt to maintain the canonical names, layouts, and side effects of the original implementation of Tempest. At the same time, it attempts to ensure portability and compatibility with modern 64-bit systems.
Why?
It's fascinating to explore the development practices used to build a modern major video game.
Why 3.3.5a?
The game and its libraries have become significantly more complex in the intervening 10+ years. By picking 3.3.5a, it's possible to imagine this implementation will eventually be complete.
Will this let me cheat in the game?
No. Tempest is a math library, and none of its routines are particularly relevant to the anti-cheat measures found in the game.
Can I use this in my own development projects?
It's probably a bad idea. The original library remains closed source, and this project is in no way official.
This project is released into the public domain.
