Face pinching - also known as the fifth largest magic in Asia, the recently very popular artbreeder you have not played may have seen it, right?

The same reason as girls holding their favorite do face templates, according to a monthly income of more than 100,000 (

The game face pincher said: What I want most here is "Liu Yifei's" face pinch data.

▲If it is not complete, it can also be kneaded

These faces, which are between 2D and 3D, seem to satisfy the common aesthetic preferences of both the second and third dimensions.

More intuitive is the use of AI technology to restore anime characters, it can be clearly seen that the biggest difference between 2D face and 3D face is that the expression of facial structure is different.

3D is a reproduction and restoration of the structure of reality, 2D is the generalization and refinement of the structure of reality, different visual angles, different aesthetic systems, naturally different painting styles.

But there are still many people who are trying to squeeze their three-dimensional faces into the two-dimensional faces.

The facial features are fine, the eyes, nose and mouth can be infinitely close to the anime through artificial means, and the most exaggerated is the contour, especially the chin chin. It can be found that almost all 2D anime characters 3D change the pointed chin to a square chin, and conversely, the 2D character 3D character is usually given a pointed chin:

The way of artistic processing is different, according to the two-dimensional face to engage in a pointed chin will only harvest a full plastic feeling, and the chin that is most in line with the 3D facial structure, whether it is wide and narrow, long and short, or thin and thick, must be adapted to the inner and outer contours, that is,: cover the inner contour, connect the outer contour.

How does it behave? How to match? How do makeup and plastic surgery work? Let's take a look.

The chin should cover the inner contour

How does the chin cover the inner contour?

The conclusion is that the performance point of the square chin cannot be wider than the inner contour line, and the performance point of the pointed chin cannot grow the inner contour line.

Specifically how to understand, we first clarify two concepts, one is the chin performance point, and the other is the inner contour line.

1. Chin expression point

Looking at the structure of the human skull, two typical chin morphologies can be summarized: square chin or pointed chin:

▲The left is a square chin, and the right is a pointed chin

The so-called round chin is usually covered with fat, and after reducing the body fat rate, it is either square or pointed.

For example, Ariel Lin and Rainie Yang, who were all babies with fat and round jaws in the early years, one became a square state and the other became a sharp state.

▲ The round-faced Zhao Liying and Zhao Lusi are also square chins

The performance point of the square chin lies in the turn of the left and right, and the person with the square chin can directly touch these two inflection points with his hand:

If there is a groove in the middle of the square chin, commonly known as the ass chin, the left and right performance points are more obvious.

The pointed chin is not as obvious as the square chin, and its performance point lies in the upper and lower light and shadow points.

The owner of a pointed chin that extends up and down usually has a shadow under the lip, which is a recessed chin-lip groove, followed by a highlight, which is the usual upward trend of the sharp chin.

After clarifying the manifestation points of the two chin forms, let's look at the second concept.

2. Inner contour line

As the name suggests, the inside of this line is the inner contour, and the outer side is the outer contour.

Connecting the turns of your brow peak and the bulge of your cheekbones, all the way along, is your inner contour line, which is better distinguished when there is light and shadow assistance.

"Chin performance point covers the inner contour", this sentence for the square chin, that is, the left and right performance points of the chin are inside the inner contour line, as shown in the figure, find the chin performance point and the inner contour line, compare the two positions:

On an inner contour line, if the brow bone is the entry point and the cheekbones are the focus point, then the left and right turns of the square chin are the foothold points, steadily undertaking each bone joint on the entire inner contour line.

There are also Yu Feihong and Zhou Yun, who fully display the beauty of the square chin, noble but not superior, dignified and not contrived.

The counterexample is the early Yang Mi, the chin is square, and the performance points on both sides are located outside the inner contour line, and the square chin at this time drags the beauty back, appearing to be national and square.

Nie Xiaoqian's chin was not so square, and the two performance points on the left and right were located on the inside of the inner contour line, so the square chin was already very beautiful.

A square chin that can cover the inner contour, even if the partial jaw is not very influential, the deviation in the appropriate category will also strengthen the personal characteristics, such as Lin Qingxia's crooked chin so that she can play the undefeated East that is both good and evil.

Shizuka Kudo and Makoto Ozawa are beautiful girls with a snide spirit and full of ghost ideas.

On the contrary, if the chin cannot cover the inner contour and exceeds the safety zone, the partial jaw will seriously affect the appearance value, and it is best to consider correction.

After saying the square chin, let's look at the pointed chin again.

For the sharp chin, holding the inner contour means that the chin performance point coincides with the inner contour line, for example, Zhang Meng's appearance is at its peak.

▲ Short chin vs long chin

Her original chin is short, can not hold the narrow and long inner contour structure, in fact, it is also green and simple, the performance point of the pointed chin is shorter than the inner contour line is acceptable, which is a style.

But if she extends her chin slightly, so that the chin performance point and the inner contour line fit as close as possible, the proportion and structure of the whole face are immediately harmonious and pleasing to the eye.

The counter-example is Zhao Lusi, unlike Zhang Meng, who has a narrow inner contour (convergence), her inner contour structure is biased towards short and wide (divergence), but her chin length does not match the inner contour structure, and the performance point of the chin exceeds the inner contour line, the transition fails, and it is disconnected from the contour.

Searching for Zhao Lusi's photos, there is a good chance that the chin is too long through angles.

In the same way, there is Liu Jialing, her inner contour is also a short and wide structure, when she was young, the chin performance point was just stuck on the inner contour line, but if the chin was slightly lengthened, it was disconnected from the inner contour, looking like the temporomandibular joint dislocation, and the chin ran away from home.

Therefore, whether it is makeup or plastic surgery, the width and length of the chin must be closely matched with the inner contour.

For the square chin, don't rush to cut off your two performance points, otherwise the entire inner contour line will always be suspended, there is no place to stay, not only the structure is unstable, but also the personal characteristics have disappeared.

You should first compare the width and narrowness of the chin performance point with the inner contour line, and when applying makeup, you can hit the shadow beyond the inner contour line, and then use highlights to brighten the middle of the chin to achieve a shift in center of gravity.

When you do face, you can cut off the part that exceeds the inner contour line, and try to retain the original facial style.

For a pointed chin, as long as the performance point does not exceed the inner contour line, whether it is a short chin or a slightly longer chin, it is an acceptable style.

But if you go beyond the inner contour line, such as when making expressions, there will still be an unnatural sense of disconnection.

If the chin manifestation point is beyond the inner contour line, it is also possible to contour and shift the focus, sweep the highlight at the chin and lip groove, and sweep the shadow at the tail, as shown in the figure

After seeing how the chin covers the inner contour, let's see how the chin should connect the outer contour.

The chin should be connected to the outer contours

Usually people with rich soft tissues, sagging skin and flesh, and good fortune have a heavier sense of volume in the outer contour, which depends on whether the thickness of the chin is harmonious with the sense of volume of the outer contour.

The thickness of the chin can be divided into: fleshy chin and bone chin.

From the side, the fleshy chin is usually at right angles or obtuse angles, looking heavy and falling, and the bone chin is usually sharply angled, looking light and sharp:

The chin should be connected to the outer contour, so the thickness of the chin is suitable for the bone mass of the face, and the thick face is matched with the thick chin, such as Yang Chaoyue:

Thin face with thin chin, such as Di Li Reba:

When the thickness of the lower bus does not match the bone mass of the face, it can be heavy and light, because the face is inherently wide and narrow.

For example, Qiu Shuzhen, who has a rich soft tissue, ends with a pointed chin, delicate and powerful, charming and elegant, intended to neutralize.

But not light and heavy, such as Kinsey Lun and Lin Yun'er, the thin upper half of the face with a water-filled chin, like a witch wearing a Snow White mask, there is a feeling of a little old lady.

Therefore, when the chin is do, the width and length should look at the inner contour, and the thickness and texture should be matched with the outer contour.

In general, hyaluronic acid chin and silicone chin have a flesh chin effect, and 3D printed chin has a bone chin effect.

People with rich facial soft tissue and full apple muscle can use 3D printed chin to balance the fleshy and greasy feeling; while people with incomplete facial tissue should not choose hyaluronic acid chin and silicone chin, otherwise the head will be unbalanced towards the lower part of the center of gravity.
