A method and apparatus are presented for displaying three-dimensional navigable display space containing an aggregation of graphical objects and an overview of the aggregation of display objects. An altered perspective is provided by compressing the horizontal dimension of the displayed objects so that a user can see a representative overview of the entire aggregation of display objects that have been selected for display together on a display screen. The compressed component is expanded so that the objects appear wider as a navigator approaches the displayed objects. A spotlight shines down on objects responsive to a data query. The spotlight serves as a navigation aid to the navigator so that highlighted items are visible from a distance and can be easily located. The user\s view of the display space is altered so that the navigator perceives that he is traveling in a straight line when approaching a display object in a display space in which the horizontal dimension of displayed objects is compressed in accordance with the apparent distance between a displayed object and the navigator.
An apparatus for increasing the number of objects displayed within a three-dimensional graphics display landscape in a display view on a computer graphics display, wherein said display view displays objects located within the three-dimensional graphics display landscape in a field of view extending
An apparatus for increasing the number of objects displayed within a three-dimensional graphics display landscape in a display view on a computer graphics display, wherein said display view displays objects located within the three-dimensional graphics display landscape in a field of view extending from a viewpoint comprising: means for laying out objects within the three-dimensional graphics display landscape; means for compressing said objects laid-out within said three-dimensional graphics display landscape along at least one dimension, wherein said means for compressing compresses said objects at a magnitude which is a function of the location of said objects relative to a predetermined landscape base point along said three-dimensional graphics display landscape; and means for expanding at least said compressed objects located within the display view, wherein said means for expanding expands said compressed objects by a magnitude which is a function of the location of said viewpoint relative to said predetermined landscape base point; and means for applying a perspective transformation to said expanded objects based on said viewpoint to render the display view.
