Hatsune Miku's first fans have been overwhelmed by the official hype, and their sense of anticipation has skyrocketed, but they don't know about some of the troubles they encountered when setting up the stage.

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

"I'm worried, if I mess up again, it's really over."

At this moment, the person in charge, He Chao, was at the scene, and he was giving thousands of instructions.

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

The follow-up work that is now being arranged is to install other sensors, and after completing this link, it is possible to operate the character with action input, which means that the scope of application can be expanded in the future.

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

At the current concert site, the first thing to do is to put a circle of ultra-thin reflective liquid crystal projectors on the venue, this ultra-thin projector is only 5mm thick, and 288 projectors are needed, and a set of projectors is about 100 US dollars, about 28,000 US dollars.

The projection system can divide the arc into groups every 30 degrees, and one group has 24 projectors.

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

If the projected image is projected directly on a screen that you look at, you will not see anything because the image projected by a set of projectors is not an angle of Hatsune Miku, but an image connected from the front to the side.

It's as abstract as Picasso's paintings.

This image is due to the unique optical design of the "virtual idol" technology development team, and the image emitted by the projectors arranged in a circular arrangement is not directly projected on the top of the projection area, but on the bottom, and then the image is projected through the cone-shaped optical parts below.

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, it will spread vertically at 60-degree intervals, but it will not spread horizontally.

The optical screen created by this principle and the projection on a flat screen are two completely different structures, so the visual design is different from that of ordinary rendering.

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

A graphics card can process eight 2400×1600 pixel pictures, and then divide them into 800×800 pixel pictures and send them to each projector, and the effect is that it can be interactive to a certain extent.

There is no doubt that the goal of He Chao's team is that Hatsune Miku will not only be able to perform on stage, but also achieve more real-time interaction in the future with the upgrading and iteration of technology.

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

……

He Chao, who was supervising the scene at the concert venue, suddenly received a message.

"Mr. Luo is here?"

After He Chao heard that the secretary came to report, he immediately ordered the work here, and did not forget to tell all the staff at the venue again, whether it was his own compatriots or employees, don't mess up.

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

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

The main purpose of his visit this time is not for the "virtual idol" plan, this is just a stopover, the main purpose is to talk to Sony about the acquisition, and Luo Sheng, the company's hot potato Cell chip related industry, is very interested.

Sony, Toshiba and IBM have been tinkering with the Cell chip for several years in a vain attempt to pick Intel off the horse, and as a result, it has become the biggest international joke in the history of chips.

But it's miserable for Sony, after being crippled by the Cell chip project several times, and still selling a PS3 at a loss of about $300, and I want to sell it with tears.

The ambitious Cell chip project has caused Sony's billions of dollars in R&D investment to the point that his mother doesn't even know it.

However, Luo Sheng did not rush to meet Sony's people when he came to Yueben, but first sent his subordinates to contact him first to see if Sony intended to sell the "legacy" of the Cell chip project, and if he intended to sell it, he would meet and talk to the other party in person.

After getting off the private jet, Luo Sheng didn't go to the hotel to rest, and he didn't need to cross half the world to get jet lag here, so he took a special car directly to the virtual concert location.

……

At the same time as Luo Sheng arrived, He Chao, the project leader of this area, had been waiting at the designated reception point for a long time, and Luo Sheng's convoy finally arrived about 20 minutes.

The trip was also quite low-key, and so far there have been no reports in the media about his coming to the city.

Several bodyguards got out of the car first, and after a while, He Chao saw Luo Sheng coming out of the car, and couldn't help but greet him: "Mr. Luo, why don't you notify me in advance when you come here, I'll make arrangements." ”

"What? Afraid that what I will see will not be done? Luo Sheng said with a smile.

"Uh...... If it had been three days ago, I would have been a little scared. He Chao said.

"Oh? Something went wrong? Luo Sheng couldn't help but look at him.

"That's right, there was a big problem with a screen three days ago, but I have already arranged it, and the new glass screen that was urgently manufactured in North America today has been sent over and installed." He Chao naturally didn't dare to hide these things, and made a gesture of invitation as he spoke, and then led Luo Sheng to the scene to inspect.

"It's inevitable that something will go wrong, just make sure the results meet expectations." Luo Sheng said casually, this matter was quickly skipped, and while walking around the scene, He Chao also briefly reported to him some work arrangements for the first virtual concert.

Don't look at this as an entertainment-oriented concert, but what Bluestar Technology does is related to high-tech, the project team of "virtual idol" has now reached more than 2,600 people, of which the technical research and development team accounts for about 60%, including hardware, software and more than 1,600 technical research and development personnel.

The Côte d'Azur has also provided technical cooperation and given a lot of technical solutions.

To hold a virtual concert, technological elements are indispensable, how to present the virtual in three dimensions and interact with reality, this is the technical work.

The reason why there are so many R&D personnel is because 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 real fans through technical means, you must solve the technical obstacles yourself, because there is no third party to provide corresponding technical solutions.

You can only grope your way forward.

Currently, we have an R&D center in Yokohama, a R&D center in North America, and an R&D center in Japan, and we are currently actively building factories for the corresponding ones.

The R&D investment in hardware equipment such as projectors and screens on the stage is basically loss-making, because the market is too small and too small, and it is basically created for virtual idols.

It can't be lacking, it must be there.

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

Being able to get the affirmation of the ultimate boss made He Chao and them very encouraged, and it was very necessary, because this project can't see real profits now, and it has been losing money, so Luo Shengman's dissatisfaction is a very key work indicator.

After staying here for about ten minutes or so, and after a general understanding of the basic situation here, Luo Sheng didn't bother the staff here, because there was also a hardware debugging and two-day rehearsal, and the schedule was very tight.

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

He doesn't have to worry about things here, there shouldn't be any problems, the biggest goal of this trip is to be able to buy the hot potato in Sony's hands, which is very valuable in Sony's hands, but it is very valuable in Luo Sheng's hands.
