Chapter 204 Motion Capture System
The next day, after breakfast, Zhong Guoqiang and others arrived at the office building where Oriental Shen Yun was located, led by Wang Mengyao.Ever since they heard that Oriental Shen Yun is a company that produces special effects for movies, Zhong Guoqiang and others have been very curious. They have only seen movies on the big screen before. As for how the movies were shot, especially the exquisite special effects in the movies It can be said that they don't know anything about how it was produced, so they all have a feeling of anticipation when they can come to the film special effects production company in person today.

As soon as everyone stepped out of the elevator, a man in his thirties with gold-rimmed glasses greeted him, and said, "Miss Wang, everyone, welcome to Oriental Shen Yun!"

After Wang Mengyao nodded to Liang Feifei, she introduced to Zhong Guoqiang and others: "This is Mr. Liang Feifan, the technical supervisor of Oriental Shenyun. The boss knows that everyone is very curious about such a company, so he arranged for Mr. Liang to show you around first."

Such a decision was of course welcomed by Zhong Guoqiang and others. They were still thinking about how to find an opportunity to turn around, but they didn't expect that the boss had already made arrangements, and they immediately became elated.

"Okay, everyone, please follow me." Liang Feifei clapped his hands to attract everyone's attention, and began to lead everyone to the office area of ​​Oriental Shenyun.

"These floors are mainly studios, which are usually used to set up sets or for keying and shooting, and sometimes they are rented to other companies to make movies. You see, the computers over there are It is used to process shooting data, and the front of the pure green background board is used for shooting, and then the real image is extracted through keying technology, and then it can be synthesized on other images that are needed. I don’t know if you have seen it In "Forrest Gump", there are many scenes where this technology is used, such as when playing table tennis, and when shaking hands with the President of the United States. If you are interested, please come here to try..." Liang Fei Fei introduced as he walked, in order to let Zhong Guoqiang and others understand what keying is, he also invited someone to demonstrate on the spot, allowing Zhong Guoqiang and others to see with their own eyes on the monitor how people disappear from the screen and how they Superimposed on other backgrounds, this magical scene aroused everyone's amazement.

"Please go this way," Liang Feifei led everyone to an office area after walking through several studios. He pointed to the busy staff and said to Zhong Guoqiang and others: "This large office area, It is our film special effects production department, those liquid transforming robots and dinosaurs running all over the ground that you see on the screen are all from this department, they can be said to use illusion to make everyone feel real..."

Zhong Guoqiang stepped forward curiously to have a look. What scene seemed to be rendered on the screen of the computer. It seemed that people wearing life jackets were floating on a sea. He couldn't help asking the staff in front of the computer: " what is this?"

Hearing someone questioning, the staff member turned his head and looked, it was a strange man standing behind him, he frowned instinctively, and then he remembered that he had been notified before that there would be people from Brother Company coming to visit today , He immediately put on a smile and replied: "This is a scene from a movie. After the ship sank, the sea is full of people waiting for rescue."

"Oh, then what kind of movie is this?" Zhong Guoqiang became even more curious. Unexpectedly, the scenes he saw on the screen could actually be produced by a computer. He couldn't help but want to ask what kind of movie this was.

"Sorry, I can't say this for the time being, but I believe you will be able to see this movie soon." The staff member replied politely, then turned his head back, and looked at the final rendering result, he felt that it did not seem to be true. Satisfied, I started to revise it again.

Zhong Guoqiang, who was hit by a soft nail, had to continue to visit with Liang Feifan. After a few more places, they followed the stairs to the 7th floor of the building.After swiping the identification card, Liang Feifan led the crowd to a transparent glass window, pointed to it and announced proudly: "Ladies and gentlemen, this is the core of our Oriental Charm. The scenes being rendered by the special effects production department that I visited are actually realized through the computer cluster inside, the scalable high-performance computer rendering cluster is equivalent to the combined rendering speed of 120 high-performance SGI workstations..."

It's a pity that Liang Feifan's words didn't arouse too much reaction. Everyone just leaned on the window and went to look inside, and didn't pay attention to what he said about 120 SGI workstations.On the contrary, the long rows of multi-layered metal cabinets seen through the glass windows, and the computer cases densely packed in the metal cabinets, aroused people's admiration, but most of them thought "there are so many computers, what if If you can use such a computer to develop games, what kind of effect will it have?"

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

It was only then that Zhong Guoqiang remembered the main purpose of coming here today, so he waved to everyone, signaling that everyone should follow Liang Feifan to visit the motion capture studio.The studio is located on the 9th floor of the building. Under the leadership of Liang Feifan, everyone went up two floors along 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 whole studio is estimated to be about a thousand square meters, but the interior is divided into several areas, some are semi-open, and some are completely open. Closed, it looks like it has different uses, and there is even a large open office area in the middle.

"This can be said to be the best and largest motion capture studio in Asia, and many famous movies' movements are produced here!" Liang Feifei said proudly with a wave of his hand.

There are all kinds of equipment piled up everywhere in the studio. Except for the computers 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 with flickering faces. With a surprised expression.

"Mr. Liang, please introduce the facilities here to everyone." Wang Mengyao put forward the request in everyone's heart in a considerate manner.

Liang Feifan glanced at everyone's expressions, clapped his hands, and said with a smile: "Okay, please follow me."

Zhong Guoqiang and others immediately gave up their plan to explore on their own, and immediately followed Liang Feifan, intending to listen to his introduction first.

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

"Look, in this semi-open room is a mechanical motion capture device, which mainly determines the motion trajectory through the angle sensor and the length of the connecting rod. This kind of motion capture device has a long history. It is said that it was first developed from the factory. Developed from the mechanical arm. The biggest advantage is 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, and it is impossible for the actors to do too much action. , 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, and some capture facial movements. For mechanical motion capture equipment, we usually call it 'monkey'." Liang Feifan pointed to a semi-open room and introduced it. He talked about the excitement, and walked over in person, gesticulating beside the equipment for a while.

Liang Feifan’s introduction elicited a burst of amazement. Zhong Guoqiang and the others had never even heard of such things as motion capture equipment, let alone talking about them before. Naturally, they would never have imagined that there are so many tricks in optomechanical motion capture equipment.

Leading everyone through the mechanical motion capture room, Liang Feifei introduced the next one: "This is an optical motion capture device, which was updated only once this year. It can capture the motions of two people at the same time, and supports multiple Up to 120 tracking points, the latest recognition system can also realize the automatic marking of the tracking points. The so-called optical motion capture is to complete the motion capture by monitoring and tracking specific light points on the target. You can see the light yellow color in the middle of the field The line marked is the performance area, and 8 high-speed cameras are installed around it. When it needs to be collected, the actor wears monochrome clothes, and sticks luminous points we call 'Marker' on the key parts of the body. Then the actors perform the required performances in the performance area, and we can use high-speed cameras to capture the entire process and turn it into the required data. The advantage of optical motion capture is that the actors do not need to connect messy cables and mechanical devices. You can move and move, and there are not many restrictions in this regard. As for the disadvantages, the price is relatively expensive, the post-processing time is relatively long, and it is sensitive to the light and reflection of the site, so you can see that the lights in this room are still The surrounding walls, floors and ceilings are specially designed."

……

"This is an acoustic motion capture device," Liang Feifei led everyone to the other end of the studio, and introduced: "Acoustic motion capture devices generally include a transmitter, a receiver, and a processing unit. It is ultrasonic, and then three ultrasonic receivers are used for triangulation to determine the position and direction. Because sound waves are easily affected by temperature, a temperature measurement device must be installed. The main advantage is that the recorded information is very rich, not only the spatial position , as well as direction information, fast speed, good real-time performance, and relatively low price. However, there are also shortcomings. First, the requirements for the venue are relatively strict. Because of the characteristics of ultrasonic waves, there should be no metal objects around, so this room is It is fully enclosed, and only a part of the middle area can be used. Except for cables, there are few other equipment in this room, just to reduce the interference to the ultrasonic wave. However, if this equipment is used for facial motion collection, it is still useful. Very convenient."

……

"This room is an electromagnetic motion capture device. You see, this is an electromagnetic data glove..." Liang Feifei introduced the equipment in the room to everyone one by one.

……

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

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