The ARToolKit video tracking libraries calculate the real camera position and orientation relative to physical markers in real time. This enables the easy development of a wide range of Augmented Reality applications. Some of the features of ARToolKit include:
* Single camera position/orientation tracking.
* Tracking code that uses simple black squares.
* The ability to use any square marker patterns.
* Easy camera calibration code.
* Fast enough for real time AR applications.
* SGI IRIX, Linux, MacOS and Windows OS distributions.
* Distributed with complete source code.
