A friend of mine took this photo at our local Indianapolis 3D User Group meeting last week. You're looking at a holographic 3D print of a 3D rendered church. In full color. Viewable from any angle. Without any special glasses required. The whole thing is less than a quarter of an inch thick.
Cameras can't do this thing justice. When looking at it with your eyes, the top of the building appears to float about 4" above the plane of the glass. While the street is recessed about 4". At some angles the building has a top, while at other angles you can see through into the Sanctuary.
The technology is called Lenticular Printing. Here's some videos that show it off better:
There's been some HD televisions released that use a 1-angle version of this tech. But we're still a few years away from a video display that would offer a 360º viewing experience when laid flat. We'll have to wait still longer for something table-sized with enough resolution for a wargame. But once that happens...
Is GW ready for this? Or the 3D printing revolution that will be the bridge between our current environment and this one? Is Mantic or Privateer prepared?
