It's the middle of May.

Both Qianjia and Alice agreed with the new equipment.

In particular, the second somatosensory device is not intended for general consumers.

This somatosensory device can be used by anchors or arcades.

However, they expressed little interest in the virtual anchor proposed by Senxia.

Alice seems to think it might be interesting if she could be an adult, but Mori Xia says that although a gentleman sells meat, a gentleman doesn't just sell meat.

As a result, Senxia focused on what he wanted to start doing, but no one cared about it.

Oh, by the way, everyone is still more interested in somatosensory handles, but there is also a question here, that is, everyone is entangled in whether the new generation of machines should continue to take the route of the current classic handle, or take the route of the somatosensory handle.

On the one hand, somatosensory controllers are really interesting and can play a lot of somatosensory games. But on the other hand, the feel of the XBOX controller is the world's top, and if it is said that it is the second in the world, then absolutely no one says that its own feel is the first in the world.

But you can't have both, and how to choose between these two handles is still quite troublesome.

Closed.

Sen Xia broke up the sunset today and was home alone.

A short time later, a seemingly sneaky figure wearing a hood and sunglasses came to the door of Senxia's house, and then knocked on the door to enter.

"Welcome...... As for that?" Sen Xia laughed when he saw the other party's dress.

"Let me go in first!"

The figure entered the room, and then he breathed a sigh of relief.

She took off her sunglasses, revealing those rare purple eyes.

"Whew...... The heat died. ”

After all, it's already May, so it's no wonder that the weather isn't hot.

The long hair hung down, and the girl breathed a sigh of relief.

"I've been more visible on the street lately, and I can't help it. Originally, I just wanted to be a voice actor......" the girl sighed.

"Well, it's hard work. Sen Xia hurriedly turned on the air conditioner, and then handed the other party a glass of cold water.

She is Ayana Amamiya, a member of the group Nanana.

Although he dreams of becoming a voice actor, for some reason, he is very good at programming.

The optimization problem of the previous somatosensory equipment was solved by her.

And she was also the support that Senxia invited over.

Yes, Qianjia and Alice are not optimistic about Senxia, and although Lihua is an assistant, her silent attitude is also obvious.

But it doesn't matter.

Senxia also has foreign aid.

However, it is not easy for Ayana to come over once, because Ayana is also a high-profile idol now, and it would be bad if she was recognized on the road.

Luckily, nothing happened.

"Where's the information? I'll take a look. After Ayana rested for a while, she said a word to Mori Xia.

Mori Xia was stunned for a moment.

Then Ayana said, "Don't worry, it's not just the code, if it's the 3D modeling itself, I've learned about it recently." ”

Just as Lihua's abilities at the game level are very foul, Ayana's mastery of programs is also very strong.

No, this ability seems to have reached a certain level of metaphysics. When Ayana sees a mistake, she can almost quickly pinpoint the source of the problem and fix it in minutes. While the other programmers were still scrambling through the code, Ayana had already done it on her side.

And the most powerful thing is that Ayana's code looks very pleasing to the eye, and she writes comments on all definitions and areas that may be more complicated, and sometimes a programmer maintains Ayana's code even more efficiently than maintaining the code she writes.

"Not taking a break?" asked Senxia.

"I've just rested. And I'm here to do something. "Ayana is quite resolute.

"Oh, good. Mori Xia nodded, and then took Ayana into the study, "The materials are all here." ”

"Well, I'll take a look first. I'll help you think about it later. ”

After Ayana finished speaking, she sat down in Mori Xia's seat.

And Senxia sighed secretly.

Working on algorithms and writing code are two completely different things.

The former is sometimes closer to a mathematical problem, while the latter is a programmer's mastery of language and logic.

Usually Mori Xia doesn't think Ayana is too prominent in these aspects, but she's just that strong.

However, Mori Xia really needs Ayana's help.

Because of the algorithm, it's not easy to do, not to mention that Ayana is actually a voice actor and idol every day. Although Ayana herself once claimed that her business hobby was computers, Mori Xia felt quite mysterious.

Because computers are all over the place. A so-called "computer hobby" can be divided into many categories.

This kind of concept is equivalent to someone saying that he likes to play games, and you think he likes hardcore games like "Wolf", but he tells you that he likes to play Lianliankan on his phone - this can't be discussed together!

Of course, Mori Xia also has a certain amount of confidence, otherwise he would not have been able to invite Ayana over. Because Ayana was indeed a big problem for the Order of the Phoenix to solve in this regard before.

Now the virtual idol of the third plan on Senxia's side, if you really want to do a good job, Ayana is such a foreign aid, it is absolutely indispensable.

Especially when Mori Xia found out that in front of Ayana, the Order of the Phoenix didn't even have a single one that could fight......

Of course, this is not to say that the technology on Mori Xia's side is not good, but it is just that Ayana's side is too over-spec.

Senxia's technology is still very strong.

For example, the motion capture technology that needs to be developed and produced for virtual idols, Mori Xia is actually very powerful. From cheap to sophisticated, they all come with a range of devices.

The simplest equipment, which requires only one camera, is now used by even many small butter companies.

Of course, if it's more professional, it's much more complicated.

For example, at present, the highest-level and most core motion capture on the Senxia side needs to call 64 advanced cameras to synchronously record the actors' whole body movements and face changes, and each motion capture actor will be equipped with three directors, one person is responsible for system shooting, and one person is responsible for checking to ensure that the best action is captured.

Of course, this is the most complicated time.

And if it's in a normal game, it's relatively simple. In particular, in some three-shaded games, the character lines are relatively simple, and the production of motion capture is mainly body movements, and facial expressions are relatively easy, so the equipment and manpower required are relatively small.

Of course, there are those that require a higher level of precision and precision.

Hollywood, for example.

After Senxia expanded its business in Hollywood, facial expression technology was also applied on a large scale. In this case, 32 cameras are used to capture the facial expressions of the faces, and each of the two cameras captures a part of the face, then stitches together the sixteen images, and finally compiles them into a 3D model.

This is not a simple job, and even this is not a job that ordinary computers can do, it requires a large number of server clusters and even supercomputers to complete.

"Would you like something to drink?" Mori Xia asked as she looked at Ayana, who was carefully flipping through the documents here.

"Black tea, remember to put sugar. Ayana didn't lift her head.

"Good. ”

Tea sets are available in the study, so it's quite convenient to make tea.

"I really don't understand why you have to use real people to capture it. Since you had a real person do the show, wouldn't it be nice to use a real person directly, why do you have to use 3D?" Ayana pursed her lips, "If you want to do it, it will be more convenient to adjust it manually." ”

"Do you know the uncanny valley theory?" Mori Xia helped Ayana make a cup of black tea and put it in front of her.

"I think I've heard of it. Ayana said, "Yes, that's the ...... Ghost in the Shell movie. ”

This concept was proposed by Professor Masahiro Mori. To put it simply, it is a robot, the closer it gets, the more people like it, but when this proximity reaches a threshold, people will become more and more afraid, but when the simulation of the puppet continues to improve, this horror will turn into love. And this zone of fear is the so-called 'uncanny valley'. ”

Mori Xia also picked up the black tea, and while tasting the fragrance of the black tea, he said: "When the robot is more than 95% similar to a human, no matter how subtle the difference, it will be particularly dazzling." And the manifestation in the game is that these characters themselves will become a terrifying existence. And the key to solving this problem is facial capture. ”

"When we first started doing facial capture, we had a lot of problems. For example, the accuracy of our cameras was not accurate enough at the beginning, so there were many areas that could not be marked properly, especially the movements of the corners of the eyes, pupils, and tongue. In this part, we initially used manual correction to adjust, but this approach can only be said to be a remedy, and the effect can only be said to be unsatisfactory. ”

"So at that time, most of the technology was three-shaded. Because the modeling of this kind of character, the facial contours and lines are much simpler than real people. ”

- Senxia used three shades and two at the beginning, on the one hand, it is in line with aesthetics, and on the other hand, as Senxia said, this is actually a technical limitation on their own side, which makes Senxia and they can only find another way to circumvent it.

And the best way to circumvent this is naturally to use a less realistic face.

Not to mention, this effect is quite good, Senxia's interactive movie can be promoted, this "tricky" action really helps a lot.

"But then we upgraded our hardware. With Alice's help, we bought a professional digital video camera. Shooting with this camera allows you to get more accurate expressions, which gives the virtual character a better soul and life than the uncanny valley – which is why we now dare to take on the Hollywood special effects business. ”

"In addition, the image can also provide material information, which is not possible with traditional motion capture methods, and this is also our advantage. ”

- The method that Senxia is talking about is actually the solution used in "Alan Wake Killer", which is another world line.

The advantage of this solution is obvious, not only does it track movements, but it also shows how the texture of the skin changes with movement.

In addition to the human figure, this technology can also be applied to animals - it is only necessary to match the actor's end expression to the corresponding 3D model.

In the other worldline, many animals and monsters also need motion capture, in fact, part of the reason is because of this.

The new technology on Senxia's side has brought them a lot of advantages.

In the past, it was necessary to choose a close motion capture actor according to the character design of the game/movie, the body shape characteristics of the character, or customize the former according to the latter. And the technique on Senxia's side can adjust the role regardless of the actor's height, body type, and age.

This is one of the secrets of the reason why Senxia's side can come up with cheap - because it greatly lowers the barrier to entry.

Of course, this approach also has a fly in the ointment, that is, if it is not a perfect match, the expression and the like are sometimes quite easy to get out of shape......

"Hey, hey, hey. You have a lot of advantages, I know ......" Ayana muttered as she continued to look at the information.

These materials are all very important things that Mori Xia brought here, but when Ayana looked at it, she looked disgusted, which made Sen Xia a little uneasy.

"Well, it looks like I've got quite a lot of work to do......" she muttered.

"Uh...... Hehehe...... "I don't know how to face you at this time, so I just have to smile, Ayana-chan......

Waited a while.

It was only then that Ayana finally put down the mouse.

"Well, it's not impossible to capture virtual characters in real time, but if you want to do it with multiple cameras...... And I'm probably just an ordinary voice actor......"

After all, not more than a decade later, some technical problems cannot rely on simple algorithms and abundant computing resources to be hard heaped.

What's more, Senxia hopes that the virtual idols on his side can be more formal and more like "idols".

Ayana agrees with this.

Idols are not so easy to do.

Even if it's a virtual idol, it's not good!

This is the heart of an idol who aspires to become a voice actor, but is now working as a programmer.

It is precisely because she knows that idols are a difficult job, so in Ayana's opinion, this thing must not be perfunctory.

However, the conditions given by Senxia are still good, and the virtual idol will have a special studio to build......

"Hmm...... Think about it. She was thinking.

"How can I help?" asked Senxia.

"Mori Xia, are you ...... Hmm, can you make lunch?"

"Hi, no problem!"

......

Two-in-one meow~

The technical issues are quite troublesome, and the algorithm is even more troublesome......
