Abstract
A computer-generated hologram (CGH) is an autostereoscopic method for displaying images without the need for special glasses. To achieve realistic 3D displays using a CGH, hidden surface removal is a key technique for displaying multiple 3D objects. However, an established method for object-light calculation considering hidden surface removal is currently not available. We describe a new algorithm considering hidden surface removal using a Z-buffer that has information for ray arrival direction. The method can display multiple-view-point 3D images and compute object light faster than the conventional method. The results of optical experiments using holograms generated by the method show us 3D images with hidden surface removal.
