Moreover, IP is considerably more feasible than holography because silver halide photography and laser technology are not required. In this respect, IP is a technology that has nearly the same advantages as holography. Therefore, viewers can see 3D objects from any position only within a certain field of view. IP, which was invented by Lippmann in 1908 and has been improved continuously, has an advantage in that it provides both horizontal and vertical parallax without the need to wear stereo glasses.Ĭurrently, popular autostereoscopic systems such as the lenticular system and parallax barrier system provide a parallax only in the horizontal direction. We adopted an integral photography (IP) in this system because IP is indisputably the most ideal system among various 3D display systems developed to date. This system can also be applied to exhibit already-extinct ancient creatures in aquariums or museums in the future. This system can also be appreciated as an artwork. The displayed fishes appear to be alive and swimming in the water, an effect achieved through three-dimensional computer graphics animation. Therefore, a stronger stereoscopic effect is obtained. A fly’s eye lens is sunk in the water resulting in larger focal length for the fly’s eye lens and an increase in the amount of popping out. Stereoscopic view is possible from all directions above the water tank through the IP and without the need for special glasses.
Therefore, we developed a new virtual aquarium through integral photography (IP), wherein virtual fishes are created with 3DCG animation and real water. Second, virtual aquariums have similar soothing effects as an actual aquarium. First, imaginary creatures and creatures that are difficult to maintain in real aquariums can be displayed. Virtual aquariums have various advantages when compared with real aquariums.
