motivation geo-media technology
provides interactivity, immersion facilitates the communication of 3D geo spatial data
applications to cartography: increase immersion into 3D geovirtual environments support for depth-cues
planar stereoscopy: well understood – rendering: straight forward supported by graphics hardware / driver
non-planar stereoscopy: provides high field-of-view and image resolution 2
problem: non-planar projection surfaces
rendering of digital 3D city and landscape models: high amount of geometry and texture data real-time constraints (> 20 frames per second)
current generation of graphics hardware (GPU) no native support for non-planar projection surfaces requires specific rendering techniques classified into image, geometry, and ray-based
approaches
hardware-accelerated stereoscopic imaging: available stereo hardware modifies vertex pipeline stage cannot be used for rendering non-planar
