A video floating around Facebook has got viewers scratching their heads. The video (above) shows a little girl with a man and woman standing on a fake ice structure, surrounded by water. Then, killer whales come rushing towards them, pushing water up onto the structure. At this point, you might be thinking the video is being filmed at SeaWorld.
But then, a polar bear wades over, climbs up and stands on its hind legs right in front of the little girl. "Fine, maybe it's a trained polar bear?" you might think. But when the bear lies down on its back, to be pet, you know something is fishy.
Penguins make an appearance, then a seal.
Now, if you're thinking something is up with this video, then you're right. None of those animals are real. Instead, the video poster attributes them to 3D projection video mapping technology.
"Projection Mapping uses everyday video projectors, but instead of projecting on a flat screen (e.g. to display a PowerPoint), light is mapped onto any surface, turning common objects of any 3D shape into interactive displays," Projection Mapping Central's website explains. "More formally, projection mapping is 'the display of an image on a non-flat or non-white surface.' "
Here, take a look at another example:
As one Facebook commenter suggests, perhaps video mapping technology like this could be a great alternative for people to see wild animals up close, rather than having to view them at parks like SeaWorld, or even zoos, where animals are kept out of their natural environments.
