Abstract
A graphics processing apparatus for computing the distance between two three-dimensional graphic elements without reducing the user's operating efficiency is provided. The graphics processing apparatus selects, from among three-dimensional objects displayed on a display, graphic elements between which the distance is to be computed, determines a projection reference in accordance with a viewing direction and geometric information on the graphic elements, and determines a projection plane in accordance with the projection reference. The graphic elements are projected onto the determined projection plane, and the minimum distance between the selected graphic elements is computed from the projected graphic elements.
