Abstract

Based on principles of panorama maps we present an interactive visualiza-tion technique that generates multi-perspective views of complex spatial environments such as virtual 3D landscape and city models. Panorama maps seamlessly combine easily readable maps in the foreground with 3D views in the background – both within a single image. Such nonlinear, non-standard 3D projections enable novel focus & context views of com-plex virtual spatial environments. The presented technique relies on global space deformation to model multi-perspective views while using a stan-dard linear projection for rendering which enables single-pass processing by graphics hardware. It automatically configures the deformation in a view-dependent way to maintain the multi-perspective view in an interac-tive environment. The technique supports different distortion schemata be-yond classical panorama maps and can seamlessly combine different visu-alization styles of focus and context areas. We exemplify our approach in an interactive 3D tourist information system.
