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.
