  • Three-dimensional graph displaying system
    Patent number: 5664077
    Abstract: A three-dimensional graph display system for displays M.times.N in number of two-dimensional graph data in a three-dimensional graph appearance. The system determines one of angular ranges derived by dividing 360.degree. into a given number of equal angular width ranges, in which a rotation angle designating a viewpoint of the three-dimensional graph is involved and selecting one of reference rotation angles set for respective angular range, corresponding to the determined angular range, selects one of a plurality of reading out orders established with respect to respective reference rotation angles for reading out the height data of the individual graph image at back side at earlier timing than that of the individual graph image at front side, corresponding to the selected reference rotation angle, as the order for reading out graph image height from M.times.
