Abstract
A navigation system and method for viewing a data landscape in an information visualization system employs constraints and positions for the rendering viewpoint which are defined relative to a bounding box enclosing objects within a volume of interest. The bounding box is resized to reflect changes in objects within the volume of interest including the addition or deletion of objects and/or the resizing of objects. The bounding box is also correspondingly repositioned whenever the volume of interest is repositioned. Constraints and/or positions defined relative to the bounding box are updated accordingly and are employed to control the movement and re-orientation of the rendering viewpoint within the volume of interest by the user. The user can select and/or define other volumes of interest within the data landscape, the bounding box for the entire landscape being the largest possible bounding box and the default volume of interest, and select predefined positions and orientations for the rendering viewpoint and/or store selected positions and/or orientations for future use.
