ABSTRACT:
A system and method of locating a selected point in a bounded area of a three-dimensional graphical environment is described in which boundary points are assigned to boundaries of the area wherein boundary axes are formed (20), a selected boundary is determined by determining the consecutive boundary axes that the viewing orientation vector lies between (21), and a selected point on the selected boundary is determined dependent on angles formed by the selected boundary, the first and second boundary axes, and the viewing orientation vector (22). The selected point coordinate is compared and matched to image object coordinates (23) to determine the selected image object.
