Abstract:
A not negligible number of information visualization techniques uses
3D-geometry to visualize data and structures. Thereby,
constantly growing data volumes influence the final visual
representation and often result in the occlusion of certain items.
Therefore, different approaches have been developed that mainly
manipulate item positions to uncover specific items of interest
or otherwise use filtering and information hiding to reduce the
amount of visible items. This paper presents a novel method to
adapt 3D-views from information visualization by the use of the
well-known illustrative technique ghost-view to successfully
address this occlusion problem. Applying ghost-views to 3D
information visualization techniques ensures the visibility of
selected items by view-dependently manipulating the transparency
of unselected data: without any manipulation of positions or
continuous context suppression. Our approach is applicable to
most 3D visualization techniques. It is interactive and easy to
adapt to existing visualization environments.
