In the opening part of the "Interstellar" movie, Murphy once complained about the appearance of ghosts in his room during his childhood, and was ridiculed by Tom, and his father Cooper was obviously not convinced, but Cooper was still patient under the persuasion of his father in law Groundly advises Murphy: If she wants to explain the unknown through science, then she must record more data, then simulate a model, and then explore the rules.

The audience learned in the second half of the story that Cooper is actually the ghost in Murphy's room.

When Cooper got lost in the tunnel of time and space, he finally appeared in a five-dimensional time and space, and he could see Murphy's room-the same scene in different timelines, he could see the past , Present and future, so Cooper tried to have a dialogue with Murphy in his childhood through the time tunnel, leaving a clue for Murphy, hoping that Murphy could take him home again.

After adulthood, Murphy finally deciphered the password that his father left in the room through the time tunnel, and solved the problem of saving the earth in one go. He became a hero to save all mankind, and finally directed his father home again.

In other words, the scene in which Cooper is in the five-dimensional time and space is vital to the core information of the entire movie, and it is also the most difficult scene in the entire movie to perform.

For this scene, Christopher built the entire hypercube!

In general, the world that people perceive is a four-dimensional space, that is, three spatial dimensions plus a time dimension, while five-dimensional space-time has four spatial dimensions, which is also called a hypercube. For most people, this is a very difficult concept to understand, and it is even more difficult to present it on the big screen.

The task of the Double Negation Company is to present this hypercube with visual special effects. From the perspective of artistic creation, they can express the whole concept in a more abstract way; but Christopher is a director who constantly challenges the limits of visual effects. They finally Still decided to complete the production in the exact shape of the hypercube.

Paul-Franklin, the visual effects director of Double Negation, has studied with astrophysicist Kip Thorne for nearly six months, and even got Kip Thorne’s notebook as a treasure to ensure Our own production team can create images that conform to the law based on real physical formulas.

The same is true for hypercubes.

At present, human beings still can’t understand the concept of the four spatial dimensions, so after discussing with Kip, Christopher and Kip arranged Cooper to fall into one of the faces of the hypercube, and then experience the hypercube from Cooper’s perspective, which is easy to understand. The way allows the audience to feel the power of time and space——

Because the faces of the cube are two-dimensional, the hypercube is three-dimensional. Nolan designed Cooper to fall into the "three-dimensional face" of the hypercube, which made Cooper not wiped out.

At the same time, Murphy’s room is located on another three-dimensional surface of the hypercube. Because of the existence of five-dimensional space-time, it seems that there is only one bookshelf between Cooper and Murphy, and the distance between the two seems to be within reach. In fact, it is separated by a long river of time and space.

According to Albert-Einstein's theory of relativity, it is impossible to go back to the past, even if one enters high-dimensional space-time. However, it is set in the movie that gravitational waves can travel through time and affect the past. This also means that if Cooper wants to change the past, he must be able to see the entire timeline, from the past to the future.

Time in the five-dimensional space-time is an entity, just like a thread, you can see every moment on the whole thread from beginning to end when you are in it; but if you try to change what happened in the past moment, you can only use gravity Bo, hinted, flapping his wings like a butterfly effect.

For this reason, Paul Franklin led the entire visual effects team to think about what it should look like in the hypercube, especially how to show the linear time that exists in the entity, and how to further use the object as a medium to show every moment on the timeline. , He must come to a perfect solution, not to make the picture chaotic, but also to ensure that the audience can observe the changes in Murphy’s room at different moments on the timeline through Cooper’s perspective.

This is almost an impossible task, but the double denial company has done it.

They reduced the six images in Murphy’s room and made each image emit two vertical lines. These two lines are the "time line". When the time lines intersect, an image of the room will be produced. Just like a quadrant, the intersection of the vertical axis and the horizontal axis can form an intersection.

Therefore, countless lines can be seen in the entire five-dimensional space-time, continuously converging to form countless room images. These images are placed on different vertical and horizontal axes, and the specific time can be accurately read according to the quadrant coordinates. Point, Cooper only needs to float vertically or horizontally along the timeline to see the past or future of Murphy's room.

Such a scene is a content that needs time to understand and digest for any audience, and it is no exception for actors. If the actor doesn’t even know what’s going on, how can he express his emotions accurately? Green screen can do it, but green screen can't help actors feel the real "time and space travel".

Then, the hypercube in front of you appeared.

The space in the center is the three-dimensional surface, which is the location of Cooper; while the other spaces are all Murphy's room, pictures on different time coordinates.

There are only five rooms now, but in the later stage, these rooms will be expanded into countless, showing all the coordinate points of the entire timeline.

The projector will also be used during actual shooting in the studio. The double negative company will project the images produced by time changes onto the surrounding curtain walls. Not only the actors, but the entire shooting team can have an intuitive understanding of the time axis inside the hypercube——

For a simple example, the space directly above may be when Murphy was five years old, the space on the right was when Murphy was sixty-five years old, and the space below was when Murphy was thirty years old. And so on.

In this way, the entire five-dimensional space-time is presented three-dimensionally in front of everyone, so that the photography team and the lighting team can understand how all the shooting tracks, pictures and angles should be selected.

Of course, in the behind-the-scenes production, digital special effects must be added to every frame of the whole scene, and the amount of engineering is unimaginable.

From the side, we can see Christopher's insistence: the combination of real scene and special effects can not only affect the performance of the actors, but also have an immeasurable impact on the entire shooting team.

When filming "Inception", Christopher built the entire corridor and placed it on a huge rotating machine, allowing Joseph Gordon Levitt to film the weightless fight in the corridor; now Christopher has built the entire five-dimensional space-time. , Let Lan Li be able to complete a "time and space journey" on the movie screen.

Timothy couldn't help but exclaimed, "So... all the models and props in the center are just for that scene?"

It was just for a trivial show, but the wisdom of hundreds of people was gathered, and the consumption of manpower and material resources was definitely not trivial.

Before today, Christopher had discussed the concept of five-dimensional space-time with Lan Li. For this reason, Lan Li also specially learned from Matthew Dunlop, and he had a basic understanding of many of the theories. Now he finally saw the entity, shocked and shocked. After the surprise, another question came to mind.

"What about the lights?"

Renly's question made Christopher cast a puzzling gaze. As for the lighting, Christopher will inevitably make adjustments according to the actual situation, so what is the problem? Lan Li could only explain it further.

"I mean the state of weightlessness. When Cooper is in the five-dimensional space-time, he is in a state of weightlessness, right? That's why he can float up and down and read the information of different time coordinates. But if only relying on power Ya, then how do you show weightlessness? Not only will the body not appear light, but it will also appear heavy."

When the actor is in the state of Wia, his limbs are off the ground, it is difficult to control his body, which also makes the influence of gravity further magnified.

In traditional oriental martial arts movies, the flying effect of flying over the wall requires human power to pull Via. This is a super difficult technical job. It is not that the master cannot achieve such an effect; and in the five-dimensional space-time, Via is Relatively static, Lanly is suspended in mid-air, and Avia doesn't have much space to pull and move—even if there is space, what Christopher needs is not flying and avoiding, but moving in the space quadrant.

This also means that the actor's actions are bound to become awkward, and the lighting effects become extremely important.

After shooting "Gravity" ~www.novelhall.com~ Lan Li also has a preliminary understanding of the creation of weightlessness, and now the first idea in my mind is lighting.

Christopher opened his mouth and was ready to answer. He thought he already had a draft, but after the words rushed to his mouth, he couldn't help but pause, showing a thoughtful look.

Christopher just stood there thinking for a moment, then just turned around and left... just left.

Lan Li and the others stayed where they were, blinked, unable to react, and looking at each other, Timothy cautiously asked, "Is the director mad?"

"Puff", the three of them couldn't help laughing.

Of course, Christopher was not out of anger, but went to find the lighting group and the VFX group-this is a very, very serious problem.

Generally speaking, the WIA problem is assigned to the martial arts stunt team, but "Interstellar Crossing" has no martial arts scenes, so naturally there is no martial arts stunt team. Now the WIA issue is completely ignored. If Lan Li hadn't realized it, they would have to wait until the problem was discovered after the shooting, and then slowly adjust, it would be even more troublesome.
