Global monopoly of technology

The first batch of Hatsune Miku fans have been stunned by the official publicity, and their sense of anticipation has soared, but they are not aware of some of the troubles they encountered when setting up the stage.

Seventy hours after the glass screen was reported to be damaged, a brand new screen was finally airlifted from North America to Tokyo as scheduled after the expedited manufacturing was completed.

"Worry a little bit, if you screw it up again, it will really be over."

At this moment, the person in charge, He Chao, was at the scene, and he was a thousand warnings.

It took about three hours or so to complete the completion of the stage transparent screen. So far, the stage hardware equipment layout of the Hatsune Miku virtual concert has basically been completed.

The follow-up work that is now being intensively arranged is to install other sensors. After this link is completed, the characters can be manipulated with action input, which means that the scope of future applications can be expanded.

In fact, the theory of realizing naked-eye 3D stereo imaging is very simple, but it can only be realized after using various technologies of hardware and software.

At the moment of the concert, we must first place a circle of ultra-thin reflective LCD projectors on the venue. This ultra-thin projector is only 5mm thick and requires 288 projectors. A set of projectors is about US$100, about 28,000. Dollar.

The projection system can divide the arc into a group every 30 degrees, and a group consists of 24 projectors.

The resolution of each set of projectors is 800×800 pixels in full color.

If you project the projected image directly on a screen that you look at directly, you can’t see anything, because the picture projected by a group of projectors is not from a certain angle of Hatsune Miku, but a picture connected from the front to the side.

It is as abstract as Picasso's paintings.

Such an image is formed because of the unique optical design of the technical development team of the "virtual idol". The image projected by the projector placed in a circular configuration is not directly projected on the top of the projection area, but below, and then passes through the cone below. Optical parts project the picture.

This conical part does not diffuse the incident light, but passes directly into the cone.

In this way, when the light is about to diverge, although it will spread in the vertical direction at 60-degree intervals, it will not spread in the horizontal direction.

The optical picture produced by this principle and the one projected on the flat screen are two completely different structures. Therefore, the visual design is also different from ordinary rendering.

Although it is 800×800 pixels, but now it is necessary to render this from the perspective of 288 cameras, so the calculation load is relatively heavy, but this problem can be solved, using cloud computing related services to solve the problem, the solution is to directly build Drawing on the cloud platform.

A graphics card can process eight 2400×1600 pixel images, and then divide them into 800×800 pixel images and send them to each projector. The result is that interaction can be achieved to a certain extent.

There is no doubt that the goal of He Chao's team is that Hatsune Miku can not only perform on stage, but also achieve more real-time interactions with future technological upgrades.

Fortunately, with the completion of the data center in Osaka, Bluestar Technology Group has opened the market for big data and cloud computing services in this small book.

...

He Chao, who was supervising live on the concert venue, suddenly received a message.

"Mr Luo is here?"

He Chao immediately ordered the work here after hearing the secretary's report, and did not forget to remind all the staff on the venue again, whether his compatriots or Japanese employees, don't mess up.

Then he was ready to receive Luo Sheng. He didn't expect that the big boss would come to Tokyo quietly.

At this moment, Luo Sheng has landed smoothly at Tokyo International Airport and has already left the airport.

His main purpose in coming to Japan this time is not for the "virtual idol" project. This is just a way. The main purpose is to talk to Sony about the acquisition. Luo Sheng, a related industry of the company's hot potato Cell chip, is very interested.

The Cell chip that Sony, Toshiba, and IBM have been working together for several years tried to slay Intel. As a result, it became the biggest international joke in the history of the chip. The capital investment is basically provided by Sony.

But for Sony, it’s miserable. After being crippled by the Cell chip project, it still loses about US$300 when selling a PS3, so I have to sell it with tears.

The ambitious Cell chip project has caused Sony's billions of dollars in research and development funds to lose money until the mother does not know it. For Sony, it is now full of ideas about how to make money and how to make up this hole.

However, Luo Sheng did not rush to meet Sony’s people when he came to Japan. Instead, he sent his subordinates to get in touch first to see if Sony’s "legacy" of the Cell chip project is intended to sell. If you intend to sell it, then personally Meet and talk with each other.

Luo Sheng did not go to the hotel to rest after getting off the private plane. There is no need to cross half of the world jet lag to come to the book, so he took the special car directly to the virtual concert location.

...

While Luo Sheng arrived, He Chao, the project leader in this area, had been waiting for a long time at the designated reception point. The Luo Sheng team finally arrived in about twenty minutes.

The trip to Japan was also quite low-key. So far, there has been no news report about his arrival in Japan.

Several bodyguards got out of the car first, and soon He Chao saw Luo Sheng coming out of the car, and he couldn't help but greeted him up: "Mr. Luo, why don't you tell me in advance when you are here, I can make arrangements."

"Why? I'm afraid I can see nothing?" Luo Sheng smiled.

"Um... if it was three days ago, I would be really scared." He Chao said.

"Oh? A mistake?" Luo Sheng couldn't help but stare at him.

"That's it. Three days ago, a screen had a big problem, but I have arranged it, and today the new glass screen made urgently in North America has been sent over and installed." He Chaonatural did not dare to hide these things. , While speaking, gestured to please, and then led Luo Sheng to inspect the scene.

"Some mistakes are inevitable, and you can ensure that the results meet your expectations." Luo Sheng said casually, this matter was quickly skipped, and while walking around the scene, He Chao also briefly reported to him for the first time Some work arrangements for the virtual concert.

Don’t think this is an entertainment-oriented concert, but Bluestar Technology’s work is related to high-tech. The “virtual idol” project team has now reached more than 2,600 people, of which the technology R&D team accounts for 60%. There are more than 1,600 technical R&D personnel including hardware and software.

The Côte d'Azur also provided technical cooperation and provided many technical solutions.

To host a virtual concert, technological elements are indispensable. How to present the virtual three-dimensionally and interact with the reality is technical work.

The reason why there are so many R&D personnel is that the "virtual idol" itself is a pioneering business, and no one has done it before, so how to make the virtual singer Hatsune Miku interact with fans in reality through technical means, You must solve the technical obstacles yourself, because there is no third party to provide corresponding technical solutions.

Can only fumble forward.

Currently there is a R&D center in Yokohama, Japan, a R&D center in North America, and a R&D center in China, and the corresponding factories are currently being actively constructed.

The investment in research and development of hardware equipment such as projectors and screens on the stage is basically at a loss, because the market is too small and too small, and it is basically built for virtual idols. At present, virtual idol singers around the world are blue. Star Technology is basically doing it by itself, so it will inevitably not return.

There is no shortage, there must be.

"In general, it's good. I saw a lot of Hatsune Miku's elements on the way here, and the publicity is in place." Luo Sheng commented after watching the scene for a few minutes.

He Chao and the others are encouraged by the affirmation of the ultimate big BOSS, and it is necessary, because this project is not really profitable now, and has been losing money, so Luo Shengman’s dissatisfaction is very important. A work indicator.

After staying here for about ten minutes or so, after understanding the basic situation here, Luo Sheng didn't bother the staff here anymore, because the next hardware debugging and two-day rehearsal were arranged in a tight schedule.

After taking a photo with the work team, Luo Sheng left here and went to the hotel to rest.

He doesn’t need to worry about things here anymore. There should be no problem. The biggest goal of this trip to Japan is to be able to buy the hot potato in Sony’s hands. It’s very much in Sony’s hands, but it’s in Luo Sheng’s hands. Very valuable.
