DiS7 (South Korea) 3D Holograms in Zoo For example, polar bears got water-bloom on their body due to an in-creased temperature of water in the zoo. In order to solve this problem, i suggest to replace some animals in zoos with 3D hologram images of those animals. 3D hologram images look very real, so it is an alternative that will protect some animals while still providing realistic, vivid impression of such animals. |
