PURPOSE:To omit display processing for useless hair arrangement and to shorten a processing time by executing hair model display processing when an hidden area is increased, and when the hidden area is not increased, omitting the hair model display processing. CONSTITUTION:When there is no hair on a required evaluating position 8, hair plotting processing is executed. An overlap buffer 8 stores an overlapped value 10 in an arrangement evaluation area 9 and the overlapped state of hair to be used for the evaluation of hair arrangement is stored in the buffer 11. When hair to be plotted is included in existing hair so as to be just overlapped, the plotting is not executed. Since the hair model 1 can be arranged so as not to observe a head model 2 and can be obtained by the minimum number of hairs required, the display processing of the hair model 1 can be rapidly executed. |
