We report on a light-field display based virtual environment
enabling multiple naked-eye users to perceive detailed
multi-gigavoxel volumetric models as floating in space, responsive
to their actions, and delivering different information in different
areas of the workspace. Our contributions include a set of specialized
interactive illustrative techniques able to provide different
contextual information in different areas of the display, as well
as an out-of-core CUDA based raycasting engine with a number of
improvements over current GPU volume raycasters.
The possibilities of the system are demonstrated by the multi-user
interactive exploration of 64GVoxels datasets on a 35MPixel light
field display driven by a cluster of PCs.
