[Don't believe what you see with your eyes, listen with your ears, touch with your hands, experience with your body and mind, and see things from multiple angles.] How exactly other people spread the famous saying, let's not mention it for the time being.

There is no doubt that what Sun Xiaoxiao encountered was 3D painting. A long, long time ago, artists were committed to using painting to make people look at 3D with the naked eye. The art did not mature until more than a decade ago during the Renaissance, and it was not introduced to China until five years later.

Although Riki had no intention of competing for fame as an artist, he still occupied the title of "the first 3D artist in China" due to the needs of the task, and various "domestic firsts" and "domestic firsts" are now produced by him.

That's an afterword.

As for the "world first"...... When the 3D painting appeared, Riki was not yet born.

More than 10 years ago, 1984 to be exact, the American painter kurtwww.xstxt.orgasterpiecesinchalk.

As a poor art with wall painting and floor painting, 3D painting is fortunate to be universally recognized by artists.

It varies greatly in difficulty. The simplest 3D drawing is actually very easy to draw, a pencil, a piece of paper, and a little sketch can try to create; Those who have a basic knowledge of sketching can get started in 3 or 4 hours by themselves, and it takes about 100 paintings to get started from beginner to beginner.

The most complex 3D painting, its artistic effect even surpasses the "Gleaner" given by the system. On the basis of mastering the 3D painting technique, it will take at least two or three months to finish the painting.

Hand-drawn (non-computer) 3D paintings can be roughly divided into three types, namely plane, facet and diamond three-dimensional painting - 3D floor painting, 3D wall painting and paper painting all belong to plane three-dimensional painting; 3D wall and floor paintings, four-dimensional 3D paintings are both faceted 3D; The rhombic surface is a 3D painting on an irregular surface.

Riki has used to draw simple 3D paintings on paper in the past, and has also visited 3D art exhibitions held by artists. To be honest, 3D painting is not as real as imagined, and it has strict requirements for viewing angles and distances.

Generally speaking, the larger the 3D painting, the closer you get to it, the more fake it will feel.

For example, the 3D wall painting and floor painting, once you have zero contact with it, the person who puts poss on it to communicate with the "human painting" will feel particularly fake. Only the videographer who holds the camera in the distance and finds the angle to shoot will feel very realistic, which is the origin of "the closer the home, the farther the real"; In contrast, a 3D drawing on paper is suitable for another method of observation. Just like a 3D painting the size of a piece of paper, you need to look at it closely to feel real, so the lens is usually very close when taking photos.

The viewing angle is more important for 3D painting than the distance.

If the painter paints a "diagonal 3D wall and floor three-dimensional painting", and the visitor has to look at it from the front. Although it is not a strange painting that is not like the four, it still feels very weird. This kind of weirdness is not difficult to imagine, just like a person who endures putting a wallpaper on his body to become a "stealth technique", and it is difficult to see the strangeness on the wall when looking at the wall at a 90° angle, but if you look at it horizontally at an angle of 0° or 180°...... The ninja was exposed.

The otherwise flat wall protrudes with a piece of belly!!

…… That's probably how strange it can be described. However, the 3D painting has the opposite sense of strangeness: "the walls that should have been uneven have become flat walls."

This is Riki's first-hand experience.

As a result, the concept of "the best viewing position" for visitors is given to 3D paintings.

How to grasp this position is the most critical factor for pear wood to be fooled; Moreover, people have adapted surnames and spread surnames, and it is difficult for the same 3D painting to maintain its deceptive effect for a long time. Therefore, the two factors of "painting location" and "number of paintings" have become the focus of this "3D trap" task.

In terms of efficiency, the 20-meter-long 3D perspective drawn on the back wall of the school road can be said to be a failure. If someone pedals a bicycle and rushes straight to the wall, they will have to bear a certain amount of responsibility.

After finishing the 3D wall painting, Limu rethought it and immediately decided to change the way he painted.

Specially designed 3D works that are easy to be limited by the terrain and are particularly small: ...... [Long-haired doorknob], [Pitted at the corner of the staircase], [False Thirteenth Steps].

Let's try to add some mental science picture effects: ...... Circles that turn, straight lines of different lengths, curves that twist on their own, etc.

And then a colorful caterpillar that wriggles on its own on the doorknob appears!

The person who opens the door will inevitably stand in front of the door, and when the key is inserted, he will see a 3D drawing at an angle of inclination, and the distance can basically be determined to be the length of an arm. This guarantees him or her the best viewing position.

Changing a painting to a small size will increase the number of paintings, and you can choose the right position at will. Although the audience is not wide, if you add relatives and friends, as well as any students and parents who may come to visit, the number of people who fall into the trap is quite significant.

Change the way you paint, and the results are outstanding!

The mission for the "3D Trap" was completed as early as mid-April -

[Special Quest - 3D Trap: Please draw 3D paintings as you like, so that 5000 people/time believe that your 3D paintings are unintentionally stepped into or dodged. Limited to 6 months. Reward for completing the task: 1 skill start-up gold / free surname point +1 / 1 skill upgrade coin, the reward depends on the completion degree. Penalty for mission failure ......]

Of course, Riki also accepted the task rewards in full this time.

Since physique, strength, and agility all increase with age, the point of freedom is still added to the mental dimension according to the convention.

[Constitution 4/4

[Spirit 15/16.]

[Power 4

Agility 4

In two and a half years, the system has released six special missions, and Riki has completed four but has no choice but to give up two. After obtaining four upgrade coins, the skills "Single-mindedness", "Meticulous Crafting", and "Image Projection" will be increased to "Lv2", "Lv1", and "Lv1", respectively, and the drawing efficiency will be dramatically improved.

With the completion of the "3D Trap", the seventh new mission will follow.

[Special Quest - Hakowa World: Continue to guide the senses of others with 3D painting, please draw a 3D panorama in an enclosed space of at least 10m*5m*3m, so that 5,000 people can be immersed. Limited to 6 months. Reward for completing the task: 1 skill start-up gold / free surname point +1 / 1 skill upgrade coin, the reward depends on the completion degree. Mission Failure Penalty: Curse of Sight. Do you want to pick it up now? 】

[Curse of Sight: I think you need to calm down and isolate yourself from the 3D world for a while.] After being cursed, you will lose your 3D vision, and you will be in a state of flat vision 90% of the time in your normal life. Penalty time: half a year. (Tip: Be careful of vehicles when crossing the road.) ）】

――Why should you be careful with your vehicle?

When she first received the task, Riki's first reaction was confusion......

As we all know, human vision is imaged by two eyes, and the three-dimensional environment that people usually see is the final effect produced by the brain after calculating the viewing angle, in which the depth and distance can be seen in just a moment. However, depth and distance are not something that can be seen by looking at them, and their internal mechanism is a rather complicated calculation in the brain's subconscious.

Therefore, people with a normal eye and a deep myopia in the other eye cannot enjoy 3D movies, and the same principle applies to people with disabilities who have vision in only one eye.

When humans lose their 3D vision, they get flat vision, and everything they see is like being presented on a piece of paper, and when a car approaches, it is impossible to judge its distance and speed through the road surface. Therefore - be careful with the vehicle.

Theoretically, 3D imaging requires two eyes to work together, but it doesn't necessarily mean that a cyclops dragon would have to be hit by a car. The glow of the reflection of objects, the trees on the side of the road, the shadows and the silhouettes all form the basis for the three-dimensional images in their minds.

What 3D painting needs to consider is not how to deceive the two eyes, but based on the flat vision of one eye, and create 3D on the plane through light and shadow, virtual reality, light and shade.

The real visual 3D three-dimensional painting is made by simulating the principle of seeing the world with the human eye and using an optical perspective. It tricks the senses of both eyes into feeling the three-dimensional relationship between the top and bottom, left and right, and front and back of the object.

The most realistic is 3D animation and raster stereoscopic painting, if you want to make a dreamlike "box garden world", it is best to use these two technologies, otherwise the diffuse area of the wall will affect the 3D effect.

However, both technologies are very dependent on computers.

A "grating" is a layer of media that separates the painting from the eye, similar to 3D glasses, and can be called "3D glasses mounted on a picture". In fact, many people have seen grating...... The most common is the raster keychain. Viewed from the left, it presents a painting; Viewed from the right, it takes on another painting.

******

"The technology is immature in this era, where do you tell me to get such a big grating!" Pear wood tangled.

Small gratings are easy to make, but even if the large gratings of 5*3, 10*3, and 10*5 are customized, no one can make a model without faults.

With the 95 years of "Toy Story", the era of 3D animation has just begun, and the 3D era has not yet left the first stage until this year!

――I also need to find a house that can be exhibited, and the minimum is 10m*5m*3m......

Of course, these troubles were half a month ago, and now he is already writing for the construction of "Hakoniwa World".
