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.N displays of a two-dimensional array of the graph image height storage means, reads out the graph image height data according to the selected reading out order and generates plotting data of the three-dimensional graph by arranging the read out graph image height data in a plotting pattern constituted of M.times.N of grids on a plotting memory in a predetermined plotting order. The plotting data is read out and output as the three dimensional graph.
