Floor-projected 3D system by 3D ready ultra short throw distance projector

This paper introduces a floor-projected 3D system and a related viewing style, face to face style 3D projection. The floor-projected 3D system, which is built on the ultra short throw distance projector, creates realistic 3D vision on the floor surface, meanwhile avoid shadow interference. And face to face style 3D projection is capable to display proper 3D image to observers on two sides of the projection area.
