Brief Introduction and viewing Methods:

What is a three-dimensional image?

3D stereoscopic painting is a painting made from the stereoscopic visual phenomenon of the human eye. Ordinary paintings and photographic works, including computer-made 3D Motion paintings, only use the human eyes to get a three-dimensional feeling of light and shade, light and shade, and virtual reality, without the use of the three-dimensional vision of the eyes, one eye is the same as two eyes. The full use of binocular stereoscopic painting will make you see a wonderful world.

I. Principles of stereoscopic vision and stereoscopic painting

People have two eyes and two eyes are at a certain distance, which leads to some differences in the image of the object between the eyes. Because the distance between the object and the eye is different, the angle of view of the two eyes will be different, because there may be some differences between the different visual perspectives, the brain will feel the three-dimensional scene based on this difference.

3D stereoscopic painting uses this principle to generate a series of repeated patterns in the horizontal direction. When these patterns overlap in two eyes, they will see a three-dimensional image.

Ii. View stereoscopic images

If you still don't want to view stereoscopic images, are you in a hurry? I will introduce how to view stereoscopic images.

There are two types of stereoscopic painting: the first one is made up of the same pattern arranged horizontally at different intervals and looks like an object of different distances. You can use any image processing software, such as Photoshop and Windows paint brushes.

Below we focus on the second form:

Another stereoscopic painting is more complex. In This stereoscopic painting, you cannot directly see the image of an object. There is only a messy image on the screen. To make such a stereoscopic painting, you can only use it.Program. The two works share the same view. The principle is to make the left eye see the image of the left eye and the right eye see the image of the right eye. (someone said, aren't you talking nonsense ?) Let me explain the specific method: When you look at stereoscopy, You need to imagine that you are enjoying the art in the glass window, that is, you do not want to look at the stereoscopy on the screen, to regard the screen as a glass window, you need to see the image inside the glass.

3. Two-Point exercise

Please draw two points that are 3 to 4 cm apart as the target. First, let your eyes rest for a moment, and then aim at the two points with a slightly blurred line of sight as you look at the distance, you can see that the two points are separated from the other two points, adjust the line of sight, and try to combine the two points into one point. When the four points are changed to three points, you will see the three-dimensional image.

4. Another way to watch

If it is difficult to look at the computer, it can be like this. If there are two points on the screen (if not, you can watch it carefully. In the horizontal direction, the picture is about 3-5 cm apart, and there is the same pattern, for example, two dots of the same color and size), you can use two deep-colored lines to vertically stick them on the display screen (you can enter the screen a little ), make the two lines vertical and connect them to the two points respectively. Then, put a small item on the top of the display for the parameter, along the edge of the display to see the reference object, move the eye focus before and after, make the left eye, left line, reference object into a straight line, the right eye, right line, and reference object are in a straight line, which can be blocked by one eye and adjusted. Then, when two eyes see the reference object, the two lines are changed to three, let the line of sight climb along the middle line into the three-dimensional screen to see the three-dimensional effect.

It is easy to use. You only need to select a background and draw another foreground.
