Abstract

In order to allow users to access a large-scale online virtual environment at any time or place, some form of mobile access is needed using for instance a PDA or SmartPhone. In this paper, we describe how the display part of our in-house developed large scale online virtual environment was adapted for mobile devices. We discuss the main issues encountered and describe our approach for 3D rendering of a large virtual environment on a PDA. More specifically, we use a hybrid geometry/image-based rendering approach in order to limit the memory requirements and processing power needed. Our experimental results, using both software and hardware accelerated rendering, show that this hybrid approach strikes an effective balance between image quality and rendering speed.
