The next day, after Zhong Guoqiang and others had breakfast, they went to the office building where Dongfang Shenyun was located under the leadership of Wang Mengyao. Since yesterday I heard that Dongfang Shen Yun is a company that does movie special effects, Zhong Guoqiang and others have been very curious, they have only seen movies on the big screen before, as for how the movie is filmed, especially how the exquisite special effects in the movie are made, it can be said that they don't know anything, so they can come to the film special effects production company in person today, they all have a sense of expectation.

As soon as everyone walked out of the elevator, a man in his thirties wearing gold-rimmed glasses greeted them and greeted, "Miss Wang, everyone, welcome to Oriental Shenyun!" ”

After nodding to Liang Feifei, Wang Mengyao introduced to Zhong Guoqiang and others: "This is Mr. Liang Feifei, the technical director of Dongfang Shenyun, the boss knows that everyone is very curious about such a company, so he arranged for Mr. Liang to take everyone to visit first." ”

Of course, such a resolution was well received by Zhong Guoqiang and others, who were still thinking about how to find an opportunity to take a turn, but they didn't expect that the boss had already arranged it, and they immediately became jubilant.

"Alright, everyone, please come with me." Liang Feifei clapped his hands, attracted everyone's attention, and began to lead everyone towards the office area of Oriental Shenyun.

"These floors are mainly sound studios, which are usually used to set up sets or keyed shots, and sometimes they are rented out to other companies to shoot films. You see, the computers over there are used to process the shooting data, and the pure green background plate is used to shoot in front of it, and then the real image is extracted through keying technology, and then it can be combined into other images that are needed. I don't know if you have watched "Forrest Gump", there are many shots in it that use this technology, such as when playing table tennis and shaking hands with the President of the United States. Everyone is interested, but come here to try it......" Liang Feifei introduced while walking, in order to let Zhong Guoqiang and others understand what is called keying, and invited someone to demonstrate it on the spot, so that Zhong Guoqiang and others could see with their own eyes from the monitor how people disappeared from the screen and how they were superimposed on other backgrounds, this magical scene attracted a burst of amazement from everyone.

"Please go this way," walked through a few studios, Liang Feifei led everyone to an office area, pointed to the busy staff, and said to China Qiang and others: "This large office area is our film special effects production department, and the liquid transformation robots and dinosaurs you see on the screen are all from this department, and they can be said to use unreal to make everyone feel the real ......"

Zhong Guoqiang stepped forward curiously to take a look, what scene seemed to be being rendered on the computer screen, as if a sea was full of people wearing life jackets, he couldn't help but ask the staff in front of the computer: "What is this?" ”

Hearing someone ask, the staff turned his head to look, it was a strange man standing behind him, he instinctively frowned, and then he remembered that he had received a notice that there would be people from the brother company to visit today, he immediately changed his smile and replied: "This is a movie scene, after the ship sank, the sea was full of people waiting for rescue." ”

"Oh, then what kind of movie is this" Zhong Guoqiang was even more curious, he couldn't imagine that the scenes he saw on the screen could really be produced by a computer, and he couldn't help but want to ask what kind of movie was in front of him.

"I'm sorry, I can't say this for now, but I'm sure you'll be able to see this film soon." The staff politely replied, then turned his head back, looked at the final rendering, and he didn't seem to be too satisfied, and began to revise it again.

Zhong Guoqiang, who had touched a soft nail, had to follow Liang Feifei to continue the visit, and after turning a few places, they followed the stairs to the 7th floor of the building. After swiping the identification card, Liang Feifei led everyone to a transparent glass window, pointed to it and proudly announced: "Ladies and gentlemen, this is the core place of our Oriental Shen Yun, and the scenes you just saw that the special effects production department is rendering are actually realized through the computer clusters in it, and the scalable high-performance computer rendering clusters are equivalent to the rendering speed of 120 high-performance SGI workstations combined......"

It's a pity that Liang Feifei's words didn't cause much repercussions, and everyone just leaned on the window to look inside, not paying attention to what he said about 120 SGI workstations or anything like that. However, the long rows of multi-layer metal cabinets seen through the glass windows, as well as the dense computer cases in the metal cabinets, attracted a sigh from everyone, but most of them thought "There are so many computers, if you can use such computers to develop games, I wonder what kind of effect it will have?" ”

Although the initial reaction was not what Liang Feifei thought, fortunately, he returned to the track he expected, and his mood felt much better. After waiting for more than ten minutes, Zhong Guoqiang and the others gradually put away their envious eyes, Liang Feifei clapped his hands again, and said to everyone: "Okay, let's go see our motion capture studio now." ”

Zhong Guoqiang remembered the main purpose of coming here today, so he waved his hand at everyone and motioned for everyone to follow Liang Feifei to visit the motion capture studio. The studio is located on the ninth floor of the building, and under the leadership of Liang Feifei, everyone walked up two floors up the stairs and poured into the motion capture studio.

As soon as he walked into the studio, Zhong Guoqiang had a very large feeling, the area of the entire studio is estimated to be almost thousands of square meters, but the interior is divided into several areas, some are semi-open, some are fully enclosed, it looks like different uses, and there is even a large open office area in the middle.

"It's arguably the best and biggest motion capture studio in Asia, and it's the place where a lot of action from famous movies comes from!" Liang Feifei waved his hand and said proudly.

There are all kinds of equipment piled up everywhere in the studio, except for the computer in the open office area, the other Zhong Guoqiang and others basically can't understand what they are doing, they look at the dazzling array of facilities, and their faces flashed with a look of surprise.

"Mr. Liang, can you introduce the facilities here?" Wang Mengyao empathetically put forward the requirements in her heart for everyone.

Liang Feifei glanced at everyone's expressions, clapped his hands, and then said with a smile: "Okay, please come with me." ”

Zhong Guoqiang and the others immediately gave up their plans to explore on their own, and immediately followed behind Liang Feifei, intending to listen to his introduction first.

After walking a few steps, Liang Feifei began to introduce: "There are four types of popular motion capture equipment, mechanical motion capture, optical motion capture, acoustic motion capture, and electromagnetic motion capture, all of which have their own advantages and disadvantages. Our studio has all four types of equipment, which is also to concentrate the strengths of the family and better serve the business of Oriental Shen Yun. ”

"You see, in this semi-open room is a mechanical motion capture device, which mainly determines the trajectory of motion through angle sensors and the length of the connecting rod, which has a long history and is said to have been developed from a robotic arm in a factory. The biggest advantages are low cost, high precision, and the ability to capture the movements of multiple actors at the same time. The disadvantage is mainly the limitations of the mechanical equipment itself, it is impossible for the actor to do too intense movements, and the functions of the equipment are relatively simple, so you can see that there are many types of equipment here, some capture body movements, some capture facial movements. When it comes to mechanical motion capture devices, we usually call them 'monkeys'. Liang Feifei pointed to a semi-open room and introduced it, said the excitement, and walked over in person, gesturing with his hand next to the equipment for a while.

Liang Feifei's introduction caused a burst of amazement, Zhong Guoqiang and others didn't talk about it before, they hadn't even heard of such things as motion capture equipment, so naturally they couldn't imagine that there were so many tricks in mechanical motion capture equipment.

Walking through the room of mechanical motion capture, Liang Feifei introduced the next room: "This is an optical motion capture device, which has only been updated once this year, which can capture the movements of two people at the same time, support up to 120 tracking points, and realize automatic marking of tracking points through the latest recognition system." The so-called optical motion capture is to complete the motion capture through the monitoring and tracking of specific light points on the target, you see that the middle of the venue is marked with a light yellow line is the performance area, 8 high-speed cameras are installed around it, when it needs to be collected, the actor wears monochrome clothes, and pastes the key parts of the body with the light point we call 'Marker', and then the actor performs the required performance in the performance area, and we can collect the whole process through the high-speed camera into the required data. The advantage of optical motion capture is that the actor doesn't need to connect a mess of cables and mechanics, and he can move as much as he wants, so there are not many restrictions in this regard. As for the disadvantages, it is more expensive, the post-processing time is relatively long, and it is sensitive to the light and reflection of the venue, so you can see that the lighting in this room and the surrounding walls and floor ceilings are specially designed. ”

……

"This is the acoustic motion capture equipment," Liang Feifei led everyone to the other end of the studio, and introduced: "The acoustic motion capture device generally includes a transmitter, a receiver and a processing unit, the transmitter actually sends ultrasonic waves, and then triangulates the position and direction through three ultrasonic receivers, because the sound waves are easily affected by temperature, so a temperature measurement device must also be installed." The main advantage is that the recorded information is very rich, not only the spatial location, but also the direction information, and then the speed is fast, the real-time performance is good, and the price is relatively low. However, there are also shortcomings, first of all, the requirements for the site are stricter, because of the characteristics of the ultrasonic itself, there can be no metal objects around, so this room is fully enclosed, and only a part of the middle area can be used, in addition to cables, there are few other equipment in this room, in order to reduce the interference of ultrasound. However, if this device is used for facial action collection, it is still very convenient to use. ”

……

"The equipment in this room is electromagnetic motion capture equipment, and you can see that this is an electromagnetic data glove...... "Liang Feifei introduced the equipment in the room one by one.

……

Liang Feifei pointed to the open office area in the middle and introduced: "This is our data processing area, and the data collected in these four rooms will be summarized here, and then processed into the required actions on the screen......

Looking at it along the way, Zhong Guoqiang and the others felt a little dizzy, and all kinds of novel equipment brought them an unparalleled impact, and correspondingly opened a new window for them. At least in Zhong's view, motion capture equipment will definitely bring a new experience to game development, and can also bring players a fresher game feeling, and he can't help but look forward to the development of "Adventure King".
