3D stereo effect
According to research, when our human eyes observe a three-dimensional object, because the two eyes are horizontally separated in two different positions, the observed object images are different, and there is an aberration between them. Because of this aberration, through the human brain, we can feel the depth and three-dimensional change of a three-dimensional world, This is the so-called stereoscopic principle. According to the principle of stereo vision, if we can see two images taken at different positions with our left and right eyes, we should be able to feel a three-dimensional space from these two images. From the previous analysis, we can know that different viewing angles will see different images. If we place the grating perpendicular to the two eyes, because the two eyes have different viewing angles to the grating, we can see two different images and have a sense of three-dimensional.
In order to get better stereoscopic effect, I don't just make it with two images, but with a series of stereoscopic images. In this case, according to different observation positions, as long as I see two images in the sequence at the same time, I can feel the three-dimensional effect.
