Datang: At the beginning, Princess Wencheng was robbed

Chapter 145 Everything is going well

can only say……

After returning from Luoyang, everything is going in a good direction.

It's time for the next 'exchange meeting'. On this day, the Jin Palace is still full of seats.

One, His Majesty and the prince are here, if you don't come, do you want to do something special?
Second, what Wei Yan said is indeed useful.

Not just a skilled craftsman, or someone with extraordinary skills.

This is because Wei Yan talked about the essence.

Not just for fun.

"Dingguo Gong, what are you going to talk about today?"

Li Zhi asked instead of his father.

Wei Yan stood on a platform that was just over one foot high, and said, "Since the last time I talked about what I heard with my ears, today I'm going to talk about what I saw with my eyes."

"Eyes see?"

Hundreds of people stared at Wei Yan closely.

"That's right! Today I want to talk about the principles of animation production - about the persistence of vision phenomenon of the human eye."

……

Half a day passed.

The person who is good at drawing quickly drew a continuous stick figure animation.

However, compared to the last time I talked about sound, this time I asked people to make stickman animations, which is a bit different.

This thing doesn't seem to be of much use, but it wastes a lot of paper.

Moreover, it seems that it can only be used as a means of having fun.

therefore……

After everyone had experienced it, Yu Zhining, the crown prince's concubine, saw that everyone around him had experienced it, so he stood up and asked: "Dong Dingguo, can I ask you something? "

"what's up?"

Wei Yan said conveniently.

"I wonder what the effect of what you said this time is?"

When Chu Suiliang saw what Yu Zhining said, he also stood up and said: "Ding Guogong, at the end of the day, is it possible that he wants us to do these things here that just anyone can do."

Wei Yan knew that the direct ministers of the Tang Dynasty would definitely feel that this was a waste of time.

Of course, Chu Suiliang can be excluded.

This Yu Zhining can barely be considered a direct minister.

He said: "Do you think that this thing seems useless and can only be made for fun?"

I saw that everyone in the audience seemed to be a little bit irrefutable.

Wei Yan then continued: "Then I can only say...you are all very wrong. This is just the most basic introduction. If you don't even understand this truth, there are countless truths behind it, and it is naturally impossible for you to understand it. .”

"What I'm telling you here today is only the foundation of this palace, and there are countless pillars and bucket arches on it."

"If you don't even know the foundation, or even think that knowing it is useless, then you will never understand what will be built later and what will be more useful."

"That's it. If you feel that you are not interested in this, you don't have to come next time."

Yu Zhining also said: "It's not that we are not interested in this, we just don't know what it is useful for."

Wei Yan: “The biggest function is to convey information, and it is more information than before.”

"To transmit information, one piece of paper is enough, so many are needed?"

Chu Suiliang also raised the bar.

Wei Yan: "Some information cannot be conveyed simply through a piece of paper."

Li Er: "Then what kind of information can this be used to convey?"

Li Er still couldn't think of any use for this thing.

But this is normal.

Wei Yan thought for a while and said: "If you want to know, you will know it on the New Year's Eve next year."

Why must it be on New Year's Eve?

Obviously, none of them understood.

……

'Exchange meeting' will be held at least twice a month.

In other words, Wei Yan can still fire at least eight or nine times before New Year's Eve next year.

enough.

In the third exchange meeting, Wei Yan talked about the principle of lens, pinhole imaging and camera obscura painting imaging.

What exactly is this camera obscura painting imaging.

Look at those oil paintings in the West, why the West can paint so 3D, especially those women with bare breasts, and the paintings are lifelike and realistic, while most of the ancient Chinese paintings are still at the stage of 2D freehand brushwork.

Everyone is playing 3D, why is China still playing 2D?

in fact……

Studies have shown that it is not how superb the painting skills of Westerners are, or how smart they are, but that they are open when they are painting.

This link is the 'principle of camera obscura painting imaging'.The figure is projected onto the canvas through the principle of small hole imaging, while the painter hides in the camera obscura and copies it on the canvas, directly coloring it.

This is like, when we were young, we took a thin piece of paper, covered it on the thing to be drawn, and then drew the general outline of the thing.

Da Vinci is said to have done the same.

Of course, as the saying goes, practice makes perfect.

When Westerners are used to this way of painting, and when they have copied to a certain extent, they can draw such exquisite pictures even without a camera obscura.

This camera obscura.

In fact, it is the predecessor of the camera.

Because as long as you use photosensitive materials to make a photosensitive plate, you can become a black and white camera worthy of the name.

Compared with the second time, the third exchange meeting can be said to be full of dry goods.

at the same time……

Wei Yan also pointed out a way for them to cheat by painting.

from now on……

As long as there are pigments, China can also draw 3D paintings similar to those in the West.

The role of the lens here is to make the image quality better and clearer.

After the exchange meeting, Wei Yan assigned a homework for everyone, that is, let them go back and think about whether the paintings in the camera obscura can be finalized directly.

Because it is too slow to draw one by one.

If it can be finalized directly, then cooperate with the persistence of vision mentioned in the second exchange meeting before.

Isn't that...

The pictures left in the camera obscura in reality can also be preserved just like the sound.Moreover, as long as the sound is combined with the image, a living person who lives on paper can be made.

Everyone was shocked by Wei Yan's bold idea.

A person who can come up with such an idea can be called a lunatic.

but!

Be reasonable!
It might actually be possible.

All the people who participated in this exchange meeting were shocked by Wei Yan's thought.

They all wanted to know, how did Wei Yan think of this?

Is this something normal people would think about?

The fourth meeting.

Those who didn't come the third time didn't come this time either.

But for the third time, this time I couldn't wait to know what Wei Yan would say next.

Then at the fourth exchange meeting, Wei Yan gave them a lecture on material science.

Talking about things that you may not be able to do with a certain material, you may switch to another material, and the effect will be better.

What Wei Yan wants to say this time is that everything is possible.

By the way, they also played a bluffing title of alchemy, and showed them how to make high-transparency glass on the spot.

Glass was still very valuable in the Tang Dynasty. For example, in the tomb of Li Jingxun in the Sui Dynasty, who was named as a child, an ordinary glass bottle was buried together as a treasure, so there is nothing wrong with saying that this is alchemy. .

But it's a pity.

Although everyone has seen that Wei Yan has refined glass, the problem is.

They didn't know how the materials in Wei Yan's hands came from.

This sucks.

Especially when Wei Yan mentioned those chemical formulas, they couldn't understand them at all.

However, they do know about the changes of Yin-Yang and Five Elements that Wei Yan mentioned.

In fact, this is similar to alchemy.

In the end, Wei Yan actually couldn't help but want to complain, if I eat the refined glass, will I be able to live forever?
But in the end, Wei Yan still didn't say anything.

otherwise……

It is estimated that some Taoists will come to ask him for an explanation.

Because isn't that an insinuation?
