We propose a new method of synthesizing computer-generated holograms (CGHs) at an arbitrary viewpoint from
multi-view images under a natural light environment. This method generates a CGH of an arbitrary viewpoint
using multi-view images from randomly arranged cameras. The method is based on a distance transformation
and a rotation of a light wave. The distance transformation interpolates a ray on the space, and the rotation is
achieved using a shift on the frequency space. A hologram was made using our method, and we confirmed that
optical reconstruction enabled us to reconstruct images of full-parallax.
