Abstract:

There has been a growing research interest in investigating techniques to combine real and virtual spaces. A variety of “reality” concepts such as Virtual Reality and Augmented Reality and their supporting technologies have emerged in the field of design to adopt the task of replacing or merging our physical world with the virtual world. The different realities can be tailored to enhance comprehension for specific design activities along a design life-cycle. This paper presents state- of-the-art applications of these “reality” concepts in design and related areas, and proposes a classification of these realities to address suitability issues for the effective utilization of the concepts and technologies. Their potentials and implications in certain design activities are also discussed.

Abstract:

We are presenting a software development framework called OSGART for Rapid Application Developement (RAD) in the domain of Mixed Reality (MR). This toolkit is being developed as an extension to OpenSceneGraph [3]. It implements a hierarchical, scenegraph based approach to marker based AR using the AR Toolkit [4]. Due to its’ tight integration with OpenSceneGraph it provides a valuable test environment for bi-directional transition between immersive Virtual Environments (IVE) and Augmented Reality (AR).

osgSWIG on Windows in combination with wxPython

OpenSceneGraph implements a comprehensive scenegraph API for OpenGL. This project utilises SWIG to generate various bindings for Python, Ruby, Java and Lua. This toolkit came to live while working on various projects around AR and VR at the HITLabNZ. HITLabNZ agreed we need to involve more people and allowed me to open it up and I subsequently moved it into a repository on Google Code under the new name osgSWIG.
