ABSTRACT
This paper discusses challenges and approaches of interaction and navigation techniques for multi-perspective views (MPVs) in the context of 3D geovirtual environments. In contrast to single-perspective views, MPVs seamlessly combine multiple views from different perspectives in one image to reduce occlusion and visual clutter while providing additional context information.
3D geovirtual environments often provide a single-perspective view and use interaction techniques that are based on ray-casting. The application of ray-cast based interaction techniques for MPVs introduces a number of technical challenges. We show how existing interaction techniques can be adapted for the application to multi-perspective city panoramas. Further, we introduce interaction techniques that enable a fast and directed exploration of virtual 3D building models based on multi-perspective detail+overview visualization.
