| Down-voted your comment because you are confusing the truth with being pedantic. This demo is neat. No question about it. I like when people play with ideas like this. The demo isn't any more a hologram or 3D than if I took four LCD's, arranged them as the sides of a cube and turned down the lights. Other than not seeing through the LCD's, the images would be the same. Again, as the person you are accusing of being pedantic said, this is no hologram and it isn't 3D in almost any imaginable way. Notice how he moves from angle to angle quickly with the camera? That's because there are no volumetrics here. It's just a flat 2D image effectively seen through a 45 degree partial mirror. It's a 2D image that appears to float in space. And it's cool. Many, many years ago I thought about the idea of installing a screen spinning or translating (harder mechanically, easier imaging) at high speed in a vacuum chamber with transparent walls and then using lasers to project slices of a true 3D scene onto it. Challenging, but it would be really interesting to see how something like that works out. |
