Virtual Aquarium: Mixed Reality Consisting of 3DCG Animation and Underwater Integral Photography

Virtual aquariums have various advantages when compared with real aquariums. First, imaginary creatures and creatures that are difficult to maintain in real aquariums can be displayed. Second, virtual aquariums have similar soothing effects as an actual aquarium. Therefore, we developed a new virtual aquarium through integral photography (IP), wherein virtual fishes are created with 3DCG animation and real water. Stereoscopic view is possible from all directions above the water tank through the IP and without the need for special glasses. 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. Therefore, a stronger stereoscopic effect is obtained. The displayed fishes appear to be alive and swimming in the water, an effect achieved through three-dimensional computer graphics animation. This system can also be appreciated as an artwork. This system can also be applied to exhibit already-extinct ancient creatures in aquariums or museums in the future.
