Long Distance Distribution of Virtual and Augmented Reality Applications

Thesis by Mathis Csisinko

Supervision by Hannes Kaufmann

Abstract

Collaboration is an intriguing and promising aspect in Virtual and Augmented Reality systems, whether participants are co-located or not. At least, distant collaboration requires distribution capabilities to replicate the Virtual Environment on all participating sites.

Studierstube is a Collaborative Augmented Reality system, providing reliable distribution in a limited way. This thesis extends these capabilities to long distance distribution, supporting ordinary IP-based networks like the Internet. Collaboration between participants located in different cities, countries and even continents becomes possible.

In order to apply these new features, Construct3D, a dynamic geometric construction tool in 3D for educational purposes, was adapted. By reducing the data amount to transmit, distribution efficiency was increased. Furthermore, robustness, exibility and scalability capabilities were improved. Distribution and collaboration features directly profit from all these efforts.
