Displays supporting stereoscopy and head-coupled motion parallax can enhance human perception of complex 3D datasets. This has been studied extensively for datasets containing 3D surfaces and 3D networks but less for so volumetric data. Volumetric data is characterized by a heavy presence of transparency, occlusion and highly ambiguous spatial structure.(More)
Dynamic view parameter adjustment can reduce visual fatigue issues in stereo displays. In a multi-scale virtual environment, which has geometric details ranging over several orders of magnitude, these adjustments are particularly important. We evaluate how two adjustment techniques interact with 7 degree-of-freedom navigation in desktop VR and a CAVE. The(More)
Learning and gaining knowledge of Roman history is an area of interest for students and citizens at large. This is an example of a subject with great sweep (with many interrelated sub-topics over, in this case, a 3,000 year history) that is hard to grasp by any individual and, in its full detail, is not available as a coherent story. In this paper, we(More)
