Huayu started as a substitute director

Chapter 399 Bodhisattva Heart
While the two sides were negotiating, Fang Hong was accompanying Liu Tianxian to inspect the film and television base.

That is the virtual reality studio. The studio has been built and the equipment has been debugged. They come to take a look and test it.

In the new city of HR District, a business bus stopped in front of the gate of the film and television base. There was no road here before, but a road has been repaired in order to build the film and television base. After all, building materials also need to be transported here.

Several people got off the car, including Fang Hong, Liu Tianxian, Chen Zhixi, photographer Liu Yin, special effects guy Yao Qi, and some other accompanying personnel.

As soon as a few people got off the car, a cold wind blew, which made them shiver and tighten their down jackets.

"It's really cold today, Siha." Chen Zhixi held his hands, blew some air, and stamped his feet, looking very cold.

There is snow on the ground, but it’s not thick. It’s just a light snow!
"Sister Chen, be careful, there is ice on the ground." Liu Tianxian was afraid that she would slip.

She was wearing a black hat, a black scarf, and a black high-end down jacket. She looked plump, but she was tall and had a graceful temperament.

It's all black, which looks cool.

"It's okay, I'm from the north and I'm used to it!" Chen Zhixi said indifferently.

However, just as she finished speaking, someone next to Liu Tianxian screamed "Oh shit", slipped, and fell backwards involuntarily.

Liu Tianxian was quick to reach out and hold him in her arms: "You really are, what else can I say? You slipped."

"I'm from the south." Fang Hong steadied himself and said that he was not used to it yet.

"I just love to talk nonsense."

Seeing that his face was red from the cold, Liu Tianxian took off the scarf from his neck and said, "Are you cold? Let me give you this scarf."

"No need!" Fang Hong refused.

"Look, your face is red from the cold, put it on." Liu Tianxian wanted to put the scarf around his neck.

"I'm a grown man, why should I wear your women's scarf? Isn't it shameful?" Fang Hong said.

"Why do you care about these things?" Liu Tianxian was about to put it on him.

"People are watching us." Fang Hong suddenly whispered.

"What are you afraid of?"

Liu Tianxian was just like her mother, afraid that Fang Hong would get cold. However, Fang Hong had his dignity and refused to use any feminine products.

The two of them interacted with each other like they were showing off their love, and the others couldn't bear to watch it, so they just smiled, shook their heads, and walked away.

Looking around, it was still very desolate, but a large wall had been built, and inside the wall there were factory-like buildings.

Some of the factory buildings have been built, while others are being built. On the steel structures, workers wearing work clothes and safety helmets are working in the cold wind.

It's quite hard to work in such a cold day. When the wind blows, they feel the biting cold, like the wind cutting my face like a knife.

Not to mention the workers standing on high places. The higher they go, the colder it is, and they have to hold steel bars and cement.

As for those buildings, they are studios, prop warehouses, set workshops and the like. The office building has not been built yet.

It’s not clear what buildings are being built now, but the virtual reality studio has been built and the equipment has been debugged.

After all, we have to shoot a movie, so I'll finish this first.

A few people walked towards the gate, where an old man wearing a thick cotton jacket was guarding the gate.

"Why let an old man guard the door in the middle of winter?" Liu Tianxian was kind-hearted and couldn't stand it.

She was still wearing her scarf, but Fang Hong refused to wear it, thinking it was too feminine and too shameful.

"He should be a temporary worker." Chen Zhixi said.

Liu Tianxian glanced at Fang Hong, who said, "Equip the workers' rooms here with heaters, hot water, blankets and everything else. There are still a few months left in the winter."

"Okay." Chen Zhixi didn't say anything, knowing that it was Liu Tianxian's kindness that came into play.

As for the old man who is the gatekeeper, what can we do? We can't let him go home and rest and enjoy his old age, right? If he has money, a stable income, social security and the like, he will definitely stay at home and enjoy his old age.

The problem is that they have no money and no security, so they come here to be gatekeepers just to make a living.

Liu Tianxian didn't say anything. She knew that this kind of thing was very common and beyond human control. She could only help those who saw it.

And this has nothing to do with Yutu, it was originally outsourced.

Seeing that Liu Tianxian was silent, Fang Hong said comfortingly, "Don't hold a grudge against me. This is all we can do."

"I know, it's okay. I just feel that I'm already living a better life than most people. At least I'm not short of material things." Liu Tianxian said.

"Well, I'm glad you know." Fang Hong nodded.

A few people chatted all the way into the virtual reality studio. It was still very warm here, with a large space, a high ceiling, and various steel frames on it, which were convenient for hanging wires and equipment.

Besides, it's very empty here, and there's no echo even if you shout.

Several people walked to a place where a technician was adjusting a high-end camera and Liu Yin was communicating with the technician.

Directly in front of the camera is an oval virtual reality world, which is a city street with high-rise buildings on both sides. It is very three-dimensional, just like 3D, and very real.

Liu Tianxian asked: "Is this true or false?"

"It's fake. We call it digital space. It's created by an engine." Fang Hong explained. In other words, this digital space is controlled by the engine. He turned around and asked, "What kind of engine is this?"

"Unreal Engine." Yao Qi said beside him.

The engine they developed themselves is not yet mature. After all, it is the first time they are shooting a movie like this, and it is not good to use an immature one.

Fang Hong walked to the camera and said to Liu Yin, "Introduce me."

"This is a motion capture camera. Although it looks similar to an ordinary camera, the difference between this camera and other cameras is that it can be directly connected to the Unreal Engine and can shoot real-life footage in a digital tracking environment." Liu Yin said.

"This metal bracket is an infrared marker. It can calculate the lens distance in the Unreal Engine. The marker position is the position of the Unreal camera." Yao Qi added, pointing to a small device.

This little device is like a satellite.
Fang Hong could roughly understand it, which was real people plus virtual reality. However, he had never played with such high-tech things, nor had he filmed such a science fiction movie, so he needed to understand more.

Don't mention him. When Xu Ke was filming the 3D "Flying Daggers of Dragon Gate", he also sought out someone to learn from him for a long time and made a short film to practice before he could get involved in this movie.

They have a learning environment and capital to practice, but ordinary people don’t have these conditions.

Liu Tianxian didn't understand at all and was completely bewildered as if he was listening to a foreign language.

"Tianxian, you go in and try taking some photos." Fang Hong motioned Liu Tianxian to go into the digital space and experience it.

Liu Yin held the camera and pointed, saying, "Sister Tianxian, stand at the small blue triangle."

"Okay." Liu Tianxian took off her down jacket and scarf and handed them to Fang Hong, revealing the sweatshirt and black pants underneath.

The pants are tight, making the legs look straight.

She followed the instructions and entered the digital space. As soon as she entered, it was as if she had entered a different world. The world seemed to be constantly changing, and she seemed to be constantly traveling back and forth.

Visually, it looks like this, but her background and the background under her feet keep changing, either in the city, or in the oasis, or on the beach or the sea.
It’s just like in the movie “Lucy”, where the heroine changed the space in Times Square with a swipe of her hand.

This made Liu Tianxian feel very novel, and in front of her was the real world, with a group of staff watching her.

The background changed to a canyon cave surrounded by rocky cliffs. Liu Yin said, "Sister Tianxian, just think of it as exploring."

Liu Tianxian turned her back and started walking forward, but she didn't really walk. She just kept standing still. As she walked, the scenery in front of her got closer. It was like she was really exploring this place. It was magical.

Of course, this has no physical effects. Physical effects need to be processed further and require a real camera.

However, it is impossible to tell the truth from the false just by looking at the picture.

"All of this data will be sent to the control station in the rear and recorded in the Unreal Engine. We can then perform real-time live-action and digital synthesis, and then send the materials to post-production processing, always keeping them synchronized with the lens." Yao Qi explained the principle next to Fang Hong.

"What if I take a wrong shot? For example, in this scene, I forgot to put a dinosaur in the front." Fang Hong pointed to the canyon in front of Liu Tianxian.

"Arrange." Yao Qi snapped his fingers, and a dinosaur suddenly appeared in front of Liu Tianxian and bit her fiercely.

"Ah!" Liu Tianxian was startled and took a step back.

However, the dinosaur disappeared in an instant and returned to its original environment.

This dinosaur looks fake. There is no vibration, no gravel, and the light does not match the environment. It just appears out of thin air without any processing.

Liu Tianxian turned around and looked at the people outside the digital space with an unfriendly look to see who was playing a trick on her.

Yao Qi looked slightly embarrassed and looked at Fang Hong; Liu Yin also looked at Fang Hong; everyone else looked at Fang Hong, their meaning was very clear.

"Just wait for me." Liu Tianxian pointed at Fang Hong and told him to be careful.

Startled her.

"What does it have to do with me? I'm just standing here." Fang Hong defended.

Liu Tianxian glared at him; Fang Hong shut up.

Everyone else laughed. They didn't expect the principal to be so henpecked.

"If an actor forgets to bring something, such as a ring or tie, or there is a blooper, it can be reshot this way, and the lighting can be edited to be consistent, so there is no need to bring a large number of people on location," Yao Qi explained the function.

This is good. If we develop it a little bit, maybe we can make it the same as the real world.

In fact, there is a difference between such virtual and real scenes.

“Unreal Engine calculates the endpoints so that the monitors here always have the correct perspective.”

Yao Qi motioned a staff member to bring something similar to a flashlight with a small square on it. He pointed at the small square and said, "This is a four-point passive marker on a flat surface. The camera will collect infrared signals through it, and the effect is exactly the same as a real flashlight."

After he said that, he turned on the flashlight. The light of the flashlight shone into the digital space, giving a visual impression of illuminating the virtual scene of the digital space.

Liu Tianxian saw it and turned back curiously: "Let me try it."

Yao Qi handed the flashlight to Liu Tianxian, and Liu Tianxian shone it on the cliffs in front of them to illuminate the environment. If you get closer, the light can be gathered, just like a real flashlight. It's amazing.

"This is actually the spotlight effect set up by the Unreal Engine." Yao Qi explained the principle.

After listening to his explanation, Fang Hong roughly understood the principle of virtual reality, that is, any scene you want can be created for you.

If you want to be in space, you can be in space; if you want to be in the sea, you can be in the sea. People can become one with such scenery.

Of course this is just a test. It would be much more complicated to shoot "Gravity".
