PURPOSE:To rapidly display a three-dimensional shape at real time and to correctly redisplay a three-dimensional shape by reforming the shape of face data in full face data, executing three-dimensional shape operation and redisplaying the operated result when input data exert influence upon another three-dimensional shape, and when the data extert no influence, computing only the face data of the input data and redisplaying the comuted result. CONSTITUTION:When face data inputted by a data input part 1 exert influence upon full face data, a three-dimensional shape operation part 4 forms two-dimensional projection data from full face data shape-reformed by a full face data shape reforming part 3, clears a three-dimensional display and displays the two-dimensional projection data. When the inputted face data exert no influence, two-dimensional data projected from the face data are formed and displayed so as to be superposed to the three-dimensional display. |
