A new integral photography (IP) technique is presented in which printing technology is used to make not only an IP image but also a fly's eye lens. IP is one of the best methods for 3D displays because both horizontal and vertical parallax can be obtained without having to wear special glasses. A fly's eye lens, which integrates a large number of small convex lenses in array form, is the key component of IP. However, such lenses had to be purchased from a limited number of commercially available options since using a metal mold to custom make them was extremely costly. This situation changed substantially with the emergence of a 3D printer that could produce highly precise and transparent lenses easily and inexpensively. We therefore used our original software to model a fly's eye lens that comprised many minute spherical lenses as a triangular mesh. The resulting STereoLithography (STL) file was then transferred to a 3D printer and a fly's eye lens was made. We also used our conventional CG technology to synthesize an IP image that integrates images observed from many viewpoints. When the image was printed with a full-color inkjet printer and the fly's eye lens was put on it, an excellent 3D image was obtained.

More about this publication?
  • For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.

    Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
