We think it is certain that 3D is better than 2D but it is very difficult to convince people.
In fact, it's best to see the the difference between 2D and 3D in real life however, that is not an easy option. So, we chose to provide 3D VR videos to give the hint of our 3D technology. Nontheless, current VR devices cannot portrait our 3D technology.
Therefore, we decided to upload some journals and thesis that might help.
