    ABSTRACT: DEEP SPACE is a large-scale platform for interactive, stereoscopic and high resolution content. The spatial and the system design of DEEP SPACE are facing constraints of CAVETM-like systems in respect to multi-user interactive storytelling. To be used as research platform and as public exhibition space for many people, DEEP SPACE is capable to process interactive, stereoscopic applications on two projection walls with a size of 16 by 9 meters and a resolution of four times 1080p (4K) each. The processed applications are ranging from Virtual Reality (VR)-environments to 3D-movies to computationally intensive 2D-productions. In this paper, we are describing DEEP SPACE as an experimental VR platform for multi-user interactive storytelling. We are focusing on the system design relevant for the platform, including the integration of the Apple iPod Touch technology as VR control, and a special case study that is demonstrating the research efforts in the field of multi-user interactive storytelling. The described case study, entitled “Papyrate’s Island”, provides a prototypical scenario of how physical drawings may impact on digital narratives. In this special case, DEEP SPACE helps us to explore the hypothesis that drawing, a primordial human creative skill, gives us access to entirely new creative possibilities in the domain of interactive storytelling.

    ABSTRACT: Principles of stereoscopic vision have long been used in geographic data processing and visualization. In recent years, a number of mainstream digital devices and systems with stereoscopic capabilities are marketed to public, making True 3D visualizations more accessible. This trend may potentially impact how spatial data is visualized in everyday life. In low-bandwidth environments, however, level of detail (LOD) management approaches have to be applied for efficient processing of large -True 3D-spatial datasets. In order to outline future research needs in True 3D visualizations, this paper presents a survey on current support provided in common Geographic Information Systems (GIS). The survey is designed to document whether the visualization modules of the selected systems a) can display 3D b) can display stereoscopic 3D c) can manage different levels of detail when displaying raster graphics. We document the names of visualization modules and report the types of stereoscopic operations, stereoscopic viewing methods and raster LOD management approaches in surveyed software. The analysis shows that all surveyed GIS support non-stereoscopic or stereoscopic 3D visualizations and a form of raster LOD management. Present raster LOD techniques in the surveyed systems are efficient for level switching when scale changes, however, unlike in other graphics processing software, none of them utilize human visual system inspired approaches. We hope that findings from this study will allow both researchers and practitioners to assess the current state of True 3D and raster LOD management support in widely used GIS software.
