Technology: The naughty kid ruined my college entrance examination, but I turned over to nuclear fus

"Elder Su, I know what you mean."

"But you listen to me first, okay?"

Lu Yu was a little crying and laughing.

This Professor Su, how did he seem to be talking to him with emotions, saying a word and interrupting a sentence....

"Okay, you say."

Professor Su was also a little impatient, and waved his hand across the screen.

At the beginning, because of Zhong Lao's recommendation, although he muttered in his heart, he actually had a lot of interest in Lu Yu.

The reason is very simple....

After all, it is the person recommended by Zhong Lao, even if it is worse, how bad can it be?

But after actual contact, in just three words, Lu Yu had already left a very bad impression on him.

"Grandiose!"

"Eyes are high and hands are low!"

"..."

This is all Professor Su's impression of Lu Yu.

Originally thinking of Zhong Lao's identity, he also thought of giving Lu Yu some advice to get him back on the right track of scientific research.

The result?

This Lu language is still not appreciated, and continues to "mess around"....

Now,

he has completely lost interest in Lu Yu, and plans to hang up the phone after a casual response.

And yet....

I only heard the microphone say: "Professor Su, in fact, I understand what you mean. "

Many of the virtual reality technology problems that our Dragon Kingdom is facing now are indeed more difficult to solve."

"But that doesn't mean these problems can't be solved."

"It's like shard decoding."

"Fragmented decoding is a technology that must be implemented for VR video playback, otherwise, retina-clear video is a disaster for computing power and network transmission..."

Professor Su, who was originally going to hang up the phone, couldn't help but be stunned when he listened to Lu Yu's series of words.

During this time, he happened to be specializing in shard decoding technology!

Shard decoding....

Although the name sounds very complicated, the actual explanation is very clear and simple.

Virtual reality derived video can be viewed 360 degrees (there are also 180 degree videos), for a 4k 360 degree 2D panoramic video, its length is 4k, the height is 2k, and the side length of this 4k needs to be finally wrapped around a 360-degree circle.

When viewers use virtual reality glasses with a 100-degree field of view, the number of pixels that the human eye can see in one direction is 1111.

But for a binocular 4K screen, the number of pixels in a single eye is 2000.

Therefore, playing 4k video on a 4k screen VR glasses is far from enough. The 4K screen should play 8K video. And so on, on the future retina screen 6kVR glasses, 12k videos need to be played!

At this time, it is the turn of fragmented decoding technology!

Only 100 degrees can be seen at the same time? Then only solve 100 degrees.

In this way, 8K video, only need to decode about 2K, the current mobile processing chip is completely fine....

However, although it sounds simple, it is difficult to operate in practice.

3D rendering, materials, models, light and shadow effects...

This is all a big problem to distinguish decoding!

For example, Professor Su is now delving into the problem that the processor cannot meet the needs of 3D rendering materials, resulting in many abnormal crashes!

This problem has been bothering him for nearly a month, but there has been no progress at all.

Even, let alone progress.

It can be said that there is no clue....

"During this time, I initially devised a technique that I named Attention Rendering. He is mainly

..." "Can take advantage of a characteristic of the human eye: although the overall FOV of the human eye is large, at the same time, people can only distinguish the scene in a small field of view..." Listening

to it, Professor Su's expression became more and more wrong.

"Wait!"

Professor Su was entangled for a moment, and then interrupted again: "

Classmate Lu Yu, can you re-explain the fixation rendering technique you just talked about?"

"I... I didn't hear clearly in some places.

Lu Yu smiled slightly and said, "Of course." "

When an image beyond 40 degrees in diameter in the center of the field of view is compressed to a resolution of 1/4, the human eye does not perceive a decrease in this resolution at all."

"That is to say, for a VR glasses with a 100-degree field of view, we can only render the scene within 40 degrees in high definition..." The

more he listened, the hotter Professor Su's breathing became:

"This... This..." A

strange light flashed in his eyes!

This technique spoken by Lu Yu can almost perfectly solve all the problems he encountered during this time!

And, not only!

If this technology can really be as Lu Yu said, then almost all the problems encountered in fragmentation decoding technology in the future can be solved!

Although this is only conceptual knowledge.

However, for the virtual reality technology industry, it can be said that it is more precious than a thousand tons of gold!

"Professor Su, do you still need me to repeat it again?"

Lu Yu smiled slightly and asked.

"I..."

Professor Su thought for a while and asked with a frown

, "Classmate Lu Yu, this idea you proposed... I feel good, but there seems to be a little problem.

"Foveated rendering technology, although it can greatly reduce the problem of computing capacity."

"But... And how do you confirm the zoom based on the turn of the eyeball?

"If there is no way to solve this problem, the foveated rendering technology you proposed can only exist as a conceptual technology at best, and there are still too many difficulties to apply it to practice."

"..."

Professor Su is worthy of being a veteran professor who has been operating in the field of virtual reality for a long time!

He listened almost twice to find out the problems in the Lu narrative.

Yes, if you want to apply the foveated rendering technique to the actual world, you must first be able to confirm where the foveated point is!

If you can't even confirm the fixation point of the eyeball, why talk about rendering based on the fixation point?

But even if it is really impossible to apply this technology to practice in a short period of time.

But to be able to come up with the theory of foveated rendering technology, and still be so young... These two points alone have definitely exceeded 99% of scientific research scholars!

At this time, Professor Su also understood a little why

Zhong Lao recommended Lu Yu to himself.

And yet....

"Professor Su, the question you asked... I also thought about it.

Lu Yu chuckled

, "If you can't even confirm the fixation point of the eyeball, you really can't apply the injection point rendering technique at all."

"But..."

"If you use eye-tracking technology, it should solve this problem very well."

Professor Su was slightly stunned: "Eye tracking technology?

"Do you have any specific ideas?"

As one of the leaders of domestic virtual reality technology, he certainly cannot be unfamiliar with eye-tracking technology.

After all, this technology has an extremely wide range of roles in the field of VR.

However

Trapped in domestic technology, eye tracking technology can only be used in the laboratory and plays a role in some small items.

If you want to really use it on the physical machine one day, there is a long way to go....

However, he actually heard the name eye tracking technology in Lu Yu's walk, which instantly aroused his interest again!

"Of course,"

Lu Yu smiled, "I have roughly three ideas now. "

One is to use contact lenses with built-in magnetic field sensors to determine the position of the eyeball by judging the strength of the magnetic field, with a stable magnetic field source..."

"The second is to judge the position of the eye by infrared scanning by receiving infrared light reflected by the cornea."

"This technology should be the easiest to complete, but there are many problems, such as the reflectivity of infrared light will cause a delay in the body..."

"The third is to judge by EOG (electrooculogram) signals, and the eye will produce a voltage difference in the middle position and non-middle position. Calculate the position of the eye by changing the EOG signal..."

When Lu Yu said these techniques, there was almost no trace of mud.

After he got these technologies from the system, the knowledge points were like a soldering iron, imprinted in his mind!

"Good fellow!"

After listening to Lu Yu's words, Professor Su was so shocked that he couldn't even close his mouth!

"In our current laboratory, we have only successfully set up one!"

"You, you..."

He didn't know what to say.

The virtual reality technology laboratory in charge of Professor Su is currently developing eye tracking technology, using the second technology mentioned by Lu Yu!

Relatively speaking, this is the simplest technique.

But, as Lu Yu says, simplicity also comes at a price....

Some problems are indeed thresholds that they can't get around at all!

First, when he went abroad for academic exchanges, he heard that Eagle Country is currently experimenting with this technology on a large scale.

But whether it will succeed is still unknown....

Third, he was almost unheard of, unseen. Even the theory is not sure if it is correct!

And Lu Yu was able to put forward all three in one breath, and he also said it head-on, how could he not be surprised?

"So be it, Professor Su."

"Some things are too cumbersome to talk about, and they are prone to technical leakage."

Lu Yu hesitated for a moment, and said slowly:

"You add my contact information, I will sort these out and send them to you for a look."

"Technically, there shouldn't be much of a problem."

"It's just that some details may need to be perfected..."

"..."

The technical stuff, dictation is still too troublesome.

It is not only the speaker who is troublesome, but also the listener, after all, many professional noun things, one or two times may not be able to hear clearly.

And once there is a point that is not heard clearly, it can be said that it is very difficult to keep up with the following content....

And directly in the form of a document, there are no such problems.

You can't see it clearly once, pull the mouse a little, drag it up a little, you can see it a second time!

"Okay."

Professor Su did not hesitate, and immediately nodded: "

Then it will trouble you."

"Thank you."

At this time, his attitude towards Lu Yu almost came to a 180-degree turn!

From the impatience at the beginning, it directly became the current posture....

Lu Yu did not hesitate and hung up the phone.

Then, he sorted out the technology about virtual reality in his mind a little and sent it to Professor Su's mailbox.

Among them, not only includes fixation point focusing technology, eye tracking technology... It also contains a comprehensive understanding of virtual reality technology in Lu Yu.

It can be said that it is a complete "experience package." "

Done!"

Lu Yu knocked the enter button, and a satisfied smile appeared at the corner of his mouth!

He had a hunch that this technology could definitely bring a earth-shaking impact on the soft power of the Dragon Kingdom!

Eagle Country, the first place in the strategic department

, is an old man with a strong air.

Although he is old, his eyes are shining, and the whole person exudes a sharpness that does not match his age!

The shoulder is engraved with a flower of three stars, which represents the position of admiral in the rank of the Eagle Country.

After looking around for a week, the old man frowned and said, "

It's a pity."

"Since the last time, our inner should send us a message, it has been targeted by the Dragon Kingdom official."

"It's almost impossible to get us the latest news."

"So, until now, we haven't figured out what the nuclear field technology that the Dragon Kingdom has broken through is..."

Finally .

. A blond middle-aged man stood up and said with an angry expression: "

Originally, we were able to figure everything out!"

"Even, we can not only figure everything out, but also get this nuclear field technology from the Dragon Kingdom!"

"But all of this has made the CIA and... That gang of bastards ruined!

"They only value their own lives, they don't..."

Before he could finish his words, a colleague next to him quickly stood up and abruptly dragged the blond middle-aged man in front of him down!

"Shut up!"

"There are some things that people of our level should consider!"

"Are you trying to die?"

The colleague hurriedly said.

The blond man had a hideous expression and said bitterly:

"I... I just can't get angry! "

How much effort and resources did we put into working with the CIA for this trip?"

"It's obviously about to succeed."

"But who knows... So inexplicably fell short?

"I'm not willing!"

With that, he slammed the table with a look of resentment.

No matter what country you are in, there is no shortage of patriots, as is the case with the Dragon Country, and the same is true in the Eagle Country.

A blond man like this is undoubtedly one of the patriots of the Eagle Country. He was very shameful of the actions of some high-ranking people, but... There was no way at all, but to watch Lu Yu return to the Dragon Kingdom.

"Also! What the hell are you..."

The colleague just wanted to organize, but at this moment, the old man who was the first

spoke up: "Okay."

"What's the point of mentioning things that have already passed?"

"What we have to do now is to think hard about which aspect we should start to curb the development of the Dragon Kingdom."

"Guys, do you have any ideas?"

His eagle-like gaze, after looking around, finally landed on a young eagle-nosed man.

"Staff Officer Mark, would you like to give me your opinion?"

“......"
