"Hello, Director Peng. My name is Liu Cixin. A middle-aged man in his 40s stood in front of Peng Yichen and introduced himself gently.

This person is Chen Xudong, a physicist at the Chinese Academy of Sciences, an astrophysicist who was just introduced to Peng Yichen.

As Chen Xudong expected, the other party heard that Peng Yichen invited him to be an astrophysics consultant for science fiction movies, and without saying a word, he immediately agreed to take over the job.

Peng Yichen was in a hurry, and sent a car to take the people directly from Kyoto City to the film and television base.

Just hearing the name of this astrophysicist, Peng Yichen was stunned for a moment, thinking that there was such a coincidence in the world.

"Hello, hello. I'm sorry, I take the liberty to ask, have you ever written science fiction?"

"I love reading science fiction. When I was in college, I tried to write a little bit myself, but unfortunately it wasn't that material, so I finally gave up. Liu Cixin replied gently.

"Oh, that's right! That's a pity, it's a pity. Peng Yichen smashed his mouth and said regretfully.

The crowd didn't know what he was sorry for.

Everyone sat down in the conference room of the special effects technology research and development center.

Peng Yichen's first question was Liu Cixin.

"Mr. Liu, thank you very much for your willingness to serve as our consultant for this film.

Just in the car, you should have read the script too.

I don't know much about the technical terms of astrophysics.

All I can tell you right now is that I wanted to make a movie that involved interstellar warfare and space jumping, with a lot of aliens in it, and a lot of the shots were set in the universe. Look at my script, are there any big flaws and problems......"

Peng Yichen pointed to the script on Liu Ci's novice hand and said his thoughts.

Since we are going to make a serious science fiction movie, there must not be too many bugs and loopholes in the movie.

However, before he finished speaking, Zhou Jingqi interrupted him.

"There's something wrong with this setting of Green Ocean. ”

"How?"

"First of all, if the planet's surface is all oceans, there will be a big problem with the water circulation system inside the atmosphere, at least a small part of the land.

Also, when this green ocean star is attacked by the silicon-based imperial fleet, if the ocean is evaporated in an instant, then the atmosphere is estimated to be completely destroyed. The water vapor should all dissipate in space in a very short period of time, instead of continuing to wrap around the entire planet......"

For some bugs raised by Liu Cixin, Peng Yichen carefully recorded them.

Unlike the movie scripts he wrote before, he had been an actor for more than 20 years in his previous life, and he studied and watched a lot of movies. The plot of classic movies, he can basically do it well.

But this time, the script of this sci-fi movie is adapted from Peng Yichen's favorite short sci-fi in his previous life.

Although he remembered most of the plot, there were many details that he couldn't remember so clearly.

So some bugs are inevitable.

After Liu Cixin finished talking about all the problems he had identified, Peng Yi was extremely grateful: "Thank you, thank you Teacher Liu for pointing out so many problems to me." ”

"It's okay, it's just common sense. I hope that Director Peng will be able to watch this film after it starts, and I am also very interested in how you can achieve such a huge interstellar war. Liu Cixin still maintained a gentle attitude and pleaded.

"No problem, you can also give us a lot of theoretical guidance on galaxies and cosmic systems on the spot, we can't ask for it. Peng Yichen said as a matter of course.

Liu Cixin listened, smiled happily and nodded, and stopped talking.

Peng Yichen looked at the small book in his hand at this time, and he also felt a little emotional.

Originally, he thought that in his previous life, the sci-fi god of Niangziguan Power Station claimed to have brought domestic sci-fi literature to the world's top level by himself.

The science fiction he wrote should be the hardest and most in line with scientific theories.

However, after listening to Liu Cixin's introduction, he realized that he was a little ignorant.

No matter how well science fiction is written, it is difficult to equate it with real science, and it is almost impossible to make a completely real science movie.

In the same way, science fiction movies are movies after all, and it is impossible to force them to be completely in line with scientific theories.

Science fiction is fantasy after all, and since it is fantasy, then it cannot be completely in line with reality.

Shooting science fiction movies by yourself, although the foundation still needs to conform to realistic science and technology theories, you can't blame them and blindly pursue practical theories.

It is necessary to pay more attention to the discussion and criticism of reality and human nature in science fiction.

Thinking about this clearly, he gave up the idea of overhauling the script, and instead handed over the existing loopholes to the two scientists, Chen Xudong and Liu Cixin, so that they could make their own scripts and provide a few revisions.

"Next, we discuss how to simulate the huge universe and interstellar warfare in the lens. Peng Yichen put forward the biggest problem in the current movie.

This belongs to Zhou Jingqi to solve.

"Director Peng, since the end of last year, you have handed over the research and development direction of special effects technology for this film shooting to us. After half a year of research, we have preliminarily determined the following two directions of shooting schemes.

The first is to integrate special effects projection technology and light box development technology to complete the shooting of space and cosmic scenes. Instead of using the traditional blue screen with computer special effects.

Through these two technologies, we can perfectly solve the problem of depth of field in space. Even with a 3D camera, we were able to see the different depths of field between different planets. Instead of being on the big screen, as was the case before, the audience could only see all the planets on one plane.

In this way, the sensory stimulation brought to them can be reached to the extreme. ”

Zhou Jingqi excitedly introduced the shooting technology they had recently developed.

Peng Yichen was also very excited when he heard this, and asked with a smile: "Then what methods do you want to achieve the two scenarios of interstellar war and stellar frog jumping?" ”

Zhou Jingqi's face became a little heavy at this time,

"The scene of the stellar frog jumping, we have figured out how to shoot it. We plan to use model projection technology. First, a huge projection wall was built, and then two huge star and starship models were built in equal proportions according to the size of the curtain wall.

When the actors perform in the battleship's operation room, they can directly see the huge laser projection equipment projected on the curtain wall through the window of the model battleship.

At this time, two sets of 3D cameras are placed in the battleship model and in front of the entire curtain wall. Shoot at the same time.

In the post-production computer compositing, we replaced the projection scene on the curtain wall with a further refined ultra-high-definition version. Meet the image quality requirements of 3D film sources.

And the wormhole generated when the frog jumped, we made a crystal ball of the same scale size as the battleship model according to the wormhole model provided by astronomy, and the center of the ball was hollowed out, and the battleship model could directly pass through the past.

On the walls of the wormhole, we asked someone to draw a clear map of the distant universe galaxies and nebulae. ”

Peng Yichen listened to the meaning of his words, and the shooting problem of the scene of the stellar frog jump should have been solved. But looking at his face, it was not very good.

It is estimated that there must have been a problem with the technology of filming interstellar war scenes.
