object is added, Told (x , y ) can be considered as zero. Entire holographic fringe pattems can be updated in real-time by this method. Fig. 3 shows the computation time by this method and conventional one. We have presented an interactive three dimensional display system and proposed effective method of increasing interactivity in it. This method is effective as long as the number of changed points is less than the half of the number of all points. Most of the cases in CAD are considered to fill this condition. Therefore we believe this method would bring a future interactive holographic display system. *Department of Electrical Engineering, Osaka City University 3-3-138, Sugimoto, Sumiyoshi-ku, Osaka, 558 Japan 1.
