Required skill-sets

osgART is a cross-platform library that simplifies the development of augmented reality applications by merging computer vision based tracking with OSG rendering. osgART's plugin-based structure supports video input from many different video sources, spatial registration from tracking libraries, such as ARToolKit, and for a variety of photometric registration techniques.

Developing an application with osgART requires two parallel skill sets:

• Firstly, skills with a tracking library and the tools for dealing with the real-world part of augmented reality. osgART is designed to work with ARToolKit (the Augmented Reality ToolKit) which provides low-level libraries for acquisition of images of the real world from video sources, marker based tracking, services for rending using OpenGL, and a variety of utilities for related tasks.
• Secondly, skills in programming using OpenSceneGraph itself. osgART adapts ARToolKits services to a scenegraph-based approach to graphics programming, rather than the procedural approach which is more typical of traditional ARToolKit applications and low-level OpenGL programming. OSG has a C++ interface. If you have skills in the C language, these can still be used with OSG in a limited way, but learning C++ is the key to unlocking the full power of the scene-graph approach.
