Background

The grating stereograph shows vivid stereoeffect of gangster world on plane by using special optical material (commonly called grating material). The hand is almost flat when touching, the eyes look stereoscopic, the foreground is prominent, the scenery is vivid, and the back scenery is profound; and each type of image can make a stereoscopic effect.

The grating stereograph is formed by combining digital technology and traditional printing output technology, and a group of sequential stereo images are used to form a picture, and the surface of the picture is covered with a layer of grating. The function of the grating is to make the light at any different point on the picture incident into the left and right eyes of the person in a specific direction. When the eyes of the human beings observe a three-dimensional object, because the two eyes are horizontally separated at two different positions, the observed object images are different, an aberration exists between the two images, and due to the existence of the aberration, the human brains can feel the depth stereo change of a three-dimensional world, namely the so-called stereo vision principle. Through the way, the wonderful and fun of the three-dimensional stereograph can be clearly and definitely felt by directly placing the picture in front of eyes without any tool.
