In our previous work, the computer-generated hologram was calculated by using the large number of object data from different viewpoints. When the fringe pattern was calculated, the calculation area is divided into small segments, and each small segment is calculated from one object data. The reconstructed image of the computer-generated hologram should not show the hole or overlap on the different viewing position. The small segment needs the several viewpoints information, especially the reconstructed image is close to the hologram plane. Therefore, the reconstructed image of the previous computer-generated hologram is concerned about the possibility of the hole or overlap. In this paper, we have proposed the improved hidden surface removal method which uses the virtual window. The calculation area, which is determined by the virtual window, is added to the object data. To apply the improved hidden surface removal method, we have achieved the more correct reconstructed image. |
