Hello everyone.
一晃眼，这个内容已经做到了第四期，承蒙各位厚爱，前三期文章一共获得了四十万的阅读量，着实让我心中暗喜不已。 虽然没有得到认证，没有多少收入，但是，自己用心写出来的东西能够得到认可，这是我最开心的事。
I will always learn with my heart, do it with my heart, and listen with my heart.
Gossip less, get to the point.
Naked-eye 3D has been all the rage since the end of the last century. In an era when entertainment was extremely scarce, a picture that could see three-dimensional shapes would instantly ignite curiosity in nature. It can be said that whoever owns such a picture book has the "priority dating rights" of the entire children's circle.
But later, with the rise of smart devices, this entertainment activity gradually faded out of everyone's vision. It wasn't until the advent of holographic projection that we discovered that naked-eye 3D not only did not disappear, but developed rapidly in corners we did not know.
Holographic projection
As mentioned in the previous article, there are many types of naked-eye 3D pictures now, and I have roughly divided them into three categories - "you can see without being blind", "hidden naked-eye 3D" and "immersive" - I have never understood that at that time, after drinking a few pounds of two pots, I could come up with such a name.
The first category, the "you can see without being blind" class
This type of naked-eye 3D diagram is characterized by being able to see without being blind.
Category 1 (1)
Category 1 (2)
Category 1 (3)
Category 1 (4)
This kind of 3D has nothing to say, just appetizers.
The second category, the "Hidden Naked Eye 3D" category
This kind of picture is the kind of picture mentioned above that instantly "yellow robe plus body" and unlocks the "priority dating rights" permission. The simple layout hides simple patterns, but it has become an indelible childhood memory for too many people.
This kind of picture viewing method: the eye focal length is positioned behind the mobile phone, after the picture becomes blurred, slowly adjust the focal length position, it will present the three-dimensional structure in the picture.

Category II (II)
Category II (III)
In the previous article, someone asked me to send more pictures of beautiful women, and I said "arrange". 我安排了，我就问你，我够讲究吧？
The voice of netizens
However, some people use the "cockfighting eye" method to watch, that is, the focus of the eyes converges between the eyes and the mobile phone, and the line of sight continues to move forward after the focus is crossed, resulting in the left eye seeing the right side, the right eye seeing the left side, and the result of seeing the opposite is that the originally raised three-dimensional structure becomes a concave structure, although the picture has a three-dimensional sense, but it is not beautiful.
Below is a picture made according to the eye method. Normal viewing is recessed, while the "cockfighting eye" method is convex, so you can also feel what a normal convex figure should look like.

The third category, the "immersive" category
See here, congratulations, the next thing you see is the really beautiful and shocking naked-eye 3D.
Note that the large screen of pad or computer will increase the difficulty of viewing, it is recommended to use a mobile phone to watch.
I mention this kind of picture in every article, but after all, every time there are new friends who click in, so I repeat this time. If you have mastered the method, the following paragraph of green text can be skipped directly; if you are not yet, please be sure to read carefully, there have been many friends who have left messages, and learned the skills to open the door to the naked-eye 3D world here.
Practice Diagram (Non-3D)
The image above has two points, and you try the following.
In the first step, the eyes are scattered, so that each point becomes a residual shadow of 2 points;
The second step, by adjusting the focal length of the eye, controls the afterimage on the right side of the left point and the afterimage on the left side of the right point, so that it coincides and becomes a clear point;
Step 3: Repeat it five times and remember the feeling of this operation. Then look at the picture below.
Exercise Diagram (1)
The method is the same as above, just replace the black dot with a planet, see the 3D effect? If you see it, congratulations, you can also see the other kinds of naked-eye 3D. 其根本宗旨就是在图中找到一个参照物，眼神涣散后，控制参照物中间两个残影重合。
(If you didn't see it before the second type of "hidden" students, you might as well go back and see the two small white circles under each picture?) The phone is close to the eye, only look at the small white circle, control the small white circle according to this method, make the middle two afterglows coincide, and then look up at the picture, what do you see? ）
再回到教程，如果刚才的方法还是没看出来，没关系，还有另外一种方法——“阿弥陀佛”法，如图。
Leonardo da Vinci, wheat field works
1. Pose as shown in the picture;
2. Gaze at any reference object in the distance, and the mobile phone is blurred with residual shadows;
3, afterglow feel that the mobile phone becomes normal size, retract the gaze to look at the mobile phone, success;
4. If not successful, repeat 3.
Let's take another star map and try it out.

When the teaching is over, the next step is the main course.
教给大家一个技巧，上图星辰图是很容易看出来的，如果复杂的图形你看不出来，你可以先点开星辰图，看出来3D效果之后，眼睛不要动，拿手机的手指往下滑，滑到下一张图，下一张图直接就可以看出来。 With a simple diagram as a guide, you will be much easier.
However, the following pictures are equipped with copywriting, remember to come back and look at it.
Category III (I)
如果一幅画中有草原、松林、远山、白云，那它将美过以往所有的诗。
Category III (II)
On a lazy summer day, in the afternoon, the glass window closed the cicadas outside the window, but could not close the slanting sun, she quietly sat on the chair, turning orange.
Category III (IV)
A touch of coolness, a touch of pearlescent.
Category III (5)
Man, there will always be something obscuring your eyes, and if you look at the sky and the tall buildings in the distance, you will know how beautiful this picture is.
Category III (VI)
No need for any scenery, one face, all the scenery.
Extra Edition
These are the naked-eye 3D pictures I took with my mobile phone, and they look good, so I can share them with you.

Today's content is these, if you feel that it is not too addictive, the series of works has completed (one), (two), (three) three, welcome to my homepage to watch.
Pay attention to one hand, it is not easy to lose. 您的阅读就是给我最大的鼓励。 如果内容让您满意，麻烦各位老爷多多点赞评论，让更多人看到，这厢先行谢过啦[大笑]
