Abstract
Techniques for creating large-scale computer holograms whose number of pixels exceeds several billions
pixels is described. The fields of virtual objects are calculated employing a technique called the
polygon-based method that numerically produces the fields of the polygonal surface sources of light.
The silhouette method that shields light behind the objects is also used to remove hidden surfaces and
reconstruct occluded three-dimensional (3D) scenes. The calculated fields of virtual 3D scenes are
numerically interfered with a reference wave, and the created binary fringe pattern is printed using a
commercially available, laser lithography system. The computer holograms created by these techniques
yield almost all depth cues without any additional equipment such as glasses and give viewers a strong
sensation of depth that has never been achieved by conventional 3D systems.
