Abstract:

3D virtual environments are increasingly used as general- purpose medium for communicating spatial information. In particular, virtual 3D city models have numerous applications such as car naviga- tion, city marketing, tourism, and gaming. In these applications, points- of-interest (POI) play a major role since they typically represent features relevant for speci c user tasks and facilitate eective user orientation and navigation through the 3D virtual environment. In this paper, we present strategies that aim at eectively visualizing points-of-interest in a 3D vir- tual environment used on mobile devices. Here, we additionally have to face the "keyhole" situation, i.e., the users can realize only a small part of the environment due to the limited view space and resolution. For the eective visualization of points-of-interest in 3D virtual environments we propose to combine specialized occlusion management for 3D scenes to- gether with visual cues that handle out-of-frame points-of-interest. We also discuss general aspects and de nitions of points-of-interest in the scope of 3D models and outline a prototype implementation of the mo- bile 3D viewer application based on the presented concepts. In addition, we give a rst performance evaluation with respect to rendering speed and power consumptions.
