Looking out of a window gives us a 3D view because our brain can handle perspective.
It’s always nice to see things in perspective, therefore, several methods are invented to make our brain think that a 2D image is more than that.

One method to get a 3D image out of 2D images is using glasses. These come in a wide variety, all working on the same principle that one eye gets a slightly shifted 2D image than the other eye.
There are two-colored (e.g. left-red, right-cyan) glasses, polarized glasses and shutter glasses to obtain the 3D effect.
The virtual reality headset also works with this principle of stereoscopy [1].

Another method to get a 3D effect is using transparent layers, like used for cartoons. This gives the viewer a sense of perspective but because the movie itself is projected on a 2D surface, there is room for improvement. You should project it on several layers to get a hologram-like movie.

This is just what Looking Glass does. It uses the transparent layer method and because every layer is projected on a corresponding surface it should give a more natural perspective.

At this moment, July 2018, the goal of the Looking Glass Factory is to make Looking Glass available at the end of 2018. In the meantime, software developers are busy to make exporters for 3D modelling packages like Maya, Blender and SolidWorks.
