Two approaches in designing autostereoscopic displays capable of providing collaborative viewing of real time 3D scenery will be presented and discussed. Both techniques provide multiscopic "look around" capabilities and are applicable for situation rooms or mobile command centers. In particular, we discuss a prospective use of these displays for interactive visualization of detailed three-dimensional models of urban areas, and the specific demands associated with managing and rendering large volumes of highly detailed information. Latest advances in scanning, survey and registration in urban areas have provided a wealth of detailed three-dimensional data and imagery. Recent events have shown a severe need and demand for systems capable in a high-level 3D visualization upon homeland security posed by terrorist actions and natural disasters within urban areas, as well as for military operations in urban terrain (MOUT). The capacity to visualize sightlines, airflow, flooding, and traffic in real time 3D within dense urban environments is increasingly critical for military and civilian authorities, as well as urban planners and city managers. Development of a high-quality 3D imaging systems is critical also for such areas as medical data imaging, gaming industry, mechanical design and rapid prototyping.
