The principle of three-dimensional printing is to simulate the distance between two eyes of a person. When shooting from different angles, the left and right pixels are recorded on the photosensitive material. When viewing, the left eye sees the left pixel and the right eye sees the right pixel. The printed matter produced according to this principle is called For three-dimensional printing.
Stereo printing has the following characteristics:
(1) It can reproduce objects realistically and has a strong three-dimensional effect. The product image is clear, the level is rich, the image is realistic, and the artistic conception is deep;
(2) The three-dimensional printed originals are often formed by modeling or scenery, and the printed matter is generally selected as high-quality coated paper and high-temperature resistant ink printing, so the gloss is good, the color is bright, and it is not easy to fade;
(3) The surface of the product is covered with a layer of concave and convex mirror-shaped grating plate, which can directly view the stereoscopic effect of the panoramic picture. From the perspective of stereoscopic vision of objects, the stereoscopic vision of objects is mainly derived from human physiological factors, experience and psychological factors. In fact, stereo vision is the stereoscopic information formed by the combination of these complex factors of appeal in the visual process. From the physiological point of view, there are parallax (two-eye parallax and monocular motion parallax), convergence, and regulation. Specifically, binocular parallax is the fundamental factor for people to obtain stereoscopic vision. In daily life, when people observe an object, the image of the object seen by the left and right eyes will be different due to the angle of view between the two eyes. Parallax, it gives people a sense of three-dimensionality.
