ABSTRACT:
When an indicating area in a three-dimensional space is entered from an input unit, an indicating area-object distance determination unit determines the distance between the indicating area and an object in the three-dimensional space on the basis of the coordinates of the indicating area and the representative coordinates of the object, which are stored in an object coordinates memory unit. A color parameter is read out from a display color memory unit in accordance with the determined distance, and the numeric value of a saturation, i.e., one of the color attributes of the object, which are stored in an object color memory unit, is rewritten with the readout color parameter. The rewritten numeric value of the saturation, together with object shape data from an object shape memory unit and object coordinate data from the object coordinates memory unit, is applied to an object display data generating unit, thereby generating object display data. This object display data is displayed on a display unit by a display control unit.
