astups/artag is a fork of ARToolKitPlus 2.1.1 ARToolKit is a software library that can be used to calculate camera position and orientation relative to physical markers in real time. This enables the easy development of a wide range of Augmented Reality applications. ARToolKitPlus is an extended version of ARToolKit's vision code that adds features, but breaks compatibility due to a new class-based API. ARToolKitPlus does not come with integrated support for VRML nor does it come with a camera library. So far, astups/artag only changes the way to build the project. Instead of using qmake it uses CMake. The other changes are only here to make it compile under Linux. This version is supported by the ASTUPS, contact: astups [at] gmail.com
