After several actors in the crew finished removing their makeup, Zhang Ran took the troupe members to find a barbecue restaurant nearby. A group of people sat around and drank cold beer and ate with relish.

Zhang Ran touched the cup with everyone, looked at Chen Zhanzhan, who was slightly quiet, and said, "Zhan Zhan, in fact, I have hesitation on the question of whether to choose you." He saw Chen Zhanzhan looking at him in confusion, so he said: "The reason why he hesitated is because this circle is too chaotic, full of open and secret contention, many people are friends in person, and all kinds of bad things are behind them." After all, there are only so many resources, and if you come out, then I will have fewer resources, so I will definitely try my best to suppress you. "Full Band Blocking Interference" is a movie with a lot of attention, and the role of Lin Yun is very likable, and you will definitely be popular after the performance. ”

Zhang Ran exhaled lightly and said, "But it will definitely attract the envy of countless people, all kinds of slander and all kinds of rumors will be inflicted on you, and even your past will be dug up." This is something I particularly don't want to see. I'm thinking, it's actually good that you're acting so down-to-earth and fighting with the world now, but I think it's a pity, if such good acting skills can't be presented on the big screen and can't be seen by more audiences, it's a pity!"

Chen Zhanzhan knew why Zhang Ran hesitated, his past experience of sitting on the stage might be dug up, and he was worried that he would be hurt. Chen Zhanzhan felt a warm feeling in her heart, thinking that Teacher Zhang is really good, but you still underestimate me! She said slowly: "A few months ago, after we finished performing "Donkey Gets Water", many audiences went backstage to send flowers. One of the men shouted at me, "Oh, isn't this Chen Jieru, you used to sit on stage in Blue Moon, but I didn't expect to be an actor now, and you changed your name to Chen Zhanzhan, I almost didn't recognize you!" I smiled and said to him, yes, I used to drink with Blue Moon, but I really don't recognize you. ”

Speaking of this, Chen Zhanzhan smiled: "Teacher Zhang, I don't think people can be defeated by others, but only by themselves! I have sat on the stage and accompanied the wine in nightclubs. There is nothing that cannot be said or dared to face. I stuck to my bottom line, I didn't sell myself, and I didn't feel like I was doing anything wrong. It was a part of my life that I was ashamed of, but now I can face it. ”

Wu Ershan and Liu Cixin were quite shocked after hearing Chen Zhanzhan's words, and even awe-inspired.

Zhang Ran smiled happily, it seemed that he was too worried, this girl was stronger than she imagined, raised her glass, and said sincerely: "You are a great girl, I salute you!"

Zhang Ran and Zhang Zichen chatted while eating, talking about performances, talk dramas, and all kinds of reality, while Zhou Xun and Liu Lu kept asking all kinds of questions like students.

After chatting for a while, Zhang Ran saw that Wu Erqi had been bowing his head and drinking alcohol, so he said, "Wu Erqi, why are you depressed?"

Urti shook his head and said: "No, I'm just thinking about whether there is any trick to make "Full Band Blocking Interference" more popular, I really don't want the movie to be smashed in my own hands." ”

Zhang Ran knew that the pressure on Urti was a bit high, so he said: "Let me give you a suggestion, the use of VR technology in "Full Band Blocking Interference" will definitely become a big selling point of the movie." ”

When Wu Erqi heard the VR technology, he asked: "VR is the thing in "Three-Body Problem", Wang Miao put it on and entered the "Three-Body Problem" game, right?"

Zhang Ran nodded and said, "Yes, it's that thing, but it's not that advanced." ”

In "The Three-Body Problem", the scientist Wang Miao puts on virtual reality equipment and enters the situation of the three-body problem game world, trekking through the vast dry land from the first perspective, and marching towards the capital of the Shang Dynasty with King Wen of Zhou and his followers. It was indeed a VR device, but the VR equipment inside was much more advanced than the current equipment, including a full-view display headset and a set of sensor suits.

Liu Cixin looked at Zhang Ran and said in surprise: "Can VR be used to make movies?"

Zhang Ran smiled and said: "Century Peak has long laid out VR, we have not only developed VR glasses, developed VR panoramic cameras, but also developed special stitching software. Seeing that Liu Cixin didn't understand, Zhang Ran explained: "The VR picture is 360 degrees, and you can't shoot all the 360-degree pictures with one lens, and you definitely need multiple lenses to shoot." After shooting, these shots need to be sewn together with special software to form a panoramic shot. Last year, "Future Apocalypse" was able to catch fire, and holographic sound played an important role, in fact, holographic sound technology was also developed for VR. ”

Liu Cixin said in surprise: "I didn't expect you to develop so many VR technologies!"

Zhang Ran said with a smile: "VR is the future development direction of the Internet, and it is necessary to make a layout. The first platform of the Internet was the computer, but in the era of mobile Internet, mobile phones have become the most important platform. We believe that in twenty or thirty years, VR will become the most important platform for the Internet. In order not to be obsolete when the VR era arrives, we must plan early. ”

Liu Cixin admired Zhang Ran greatly, thinking that it is not enough to seek the world, Zhang Ran is so successful is really reasonable, this vision is too strong, and said sincerely: "VR is a technology that belongs to the future, I think VR will trigger a revolution about the state of human existence." It will lead to the second great migration in human history. From the reality of the present, migrate to the illusory world of the future. ”

Wu Ershan is not interested in the development of VR, he is concerned about whether VR can be used in movies, and how to use it in movies, so he said: "Now VR can be used to make movies?"

Zhang Ran didn't explain much: "Tomorrow the two of you come to my house and experience it for yourself!"

The next morning, Wu Erxi and Liu Cixin arrived as promised.

Zhang Ran took them into the study, turned on the computer, took out a VR eye and handed it to Wu Ershan, explained it briefly, and then asked Wu Ershan to put it on and try it.

Urshan put on VR goggles, and what appeared in his eyes was the vast sea, and he was sitting in a kayak. Ulti looked to the left and right, and saw that the picture could really turn with his head. He looked up again, and the sky above him was blue and white clouds. He was really amazed and thought, this thing is so advanced!

Just then, Urti suddenly saw a shark swimming towards him. Although he knew that this was a movie and a fake, his heart still beat violently, and even breathing became a little difficult, and the whole person involuntarily took a step back.

After the experience, Wu Ershan took off the VR glasses and handed them to Liu Cixin: "Try it, this thing is really awesome!"

Liu Cixin didn't say a word, took over the VR eyes, entered the game world, and began to experience the shock brought by VR.

After Liu Cixin finished the experience and took off the VR glasses, Zhang Ran asked, "How do you feel?"

Liu Cixin said with a shocked face: "It's so shocking, I feel that I am really in the game world, instead of observing the world through the screen as before, you can naturally observe the world by turning your head, turning around, walking around, etc., instead of using the mouse and keyboard to control your observation method as before." ”

Wu Erxi has the same opinion as Liu Cixin, but he did not talk about the advantages: "It is very shocking, but unfortunately the resolution is too low, the picture is relatively blurry, and the graininess is particularly serious." It's like how we watched a video on the Internet ten years ago, and it's a reminder that this is a game!"

Zhang Ran nodded and said: "The biggest problem with VR now is that the resolution is not enough, and the graininess is serious. At present, the mainstream VR resolution on the market is 640x800 per eye, and a few manufacturers have achieved 960x1080 resolution per eye. The VR you just experienced, with a resolution of 1080x1200 per eye, a total of 2160x1200 for both eyes, and a refresh rate of 90Hz, it can be said that it is the most advanced VR equipment at present. According to research, each eye must have a resolution of 16K and a frame rate of 144 FPS for the VR picture to reach the perfect state. It will take at least 20 years for the display to reach this resolution, plus problems such as vertigo, and VR technology will take at least 20 years to mature!"

Urti opened his mouth and said, "It will take another 20 years, which means that it is impossible to have a large-scale epidemic in the short term!"

Zhang Ran said with a smile: "That's not necessarily, the movie has been developed for decades before it is mature, but the popularity of the movie has not waited that long." According to research, the human eye does not pay attention to all the details during the process of seeing, and only the middle visual focus is most sharp. Based on this principle, there is a foveated rendering technology, which is based on eye tracking, which divides the picture into three areas, namely the visual center, the visual edge, and the middle transition area, and renders them at 100%, 20% and 60% resolution respectively. ”

Zhang Ran paused and smiled confidently: "Based on this theory, our company's engineers came up with an idea to add a layer of lenses to the VR glasses, and use an OLED microdisplay to project the image on this layer of lens and then onto the lens, so that the higher resolution of the center part of the headset field of view can hide a single pixel. The center of the field of view will have a smaller, high-density display, while the left and right sides will have a lower-resolution display. The VR glasses will then use gaze trajectories and software analysis to better render the user's gaze focus in the virtual scene, so that the user's center focus is always in the high-resolution part. If this idea can be realized, the audience will be able to experience 8K image quality on a 2K screen. Now that some progress has been made in R&D, the lab plans to launch a prototype by the end of next year and distribute hundreds of pilot products to improve through user feedback and strive to put the product on the market in 2015. ”

Zhang Ran looked at Wu Erqi and said with a smile: "If the prototype can be launched next year, the experience brought by the 8K image quality will definitely be shocking, and it will definitely set off a VR boom around the world!"

Urti has just felt the shock brought by VR, and the picture just now is only 1K, and the new technology can bring 8K feeling, and the shock is absolutely beyond imagination. He swallowed his saliva and said, "I believe that the shock brought by 8K image quality is absolutely beyond imagination, but VR can't be edited, only one shot to the end." A movie like "Full Segment with Blocking Interference" can't be made with one shot. ”

Zhang Ran dared to suggest the use of VR, so he naturally didn't talk nonsense, so he said: "It's impossible to use VR for all content, editing, shooting, and cost are all problems, and the audience can't stand it." We can use VR partially, using 2D plus VR shooting, and most of the scenes are ordinary 2D pictures, with one or two VR segments inserted in the middle. When watching 2D, the audience watches normally, and when the VR lens comes out, the audience puts on VR glasses to watch. ”

Ulti said puzzledly: "But how do the audience know which is the camera and which is the VR lens?"

Zhang Ran said with a smile: ""The Whole Section with Blocking Interference" is the same as "Future Apocalypse", soldiers will wear exoskeleton armor when fighting. When the division commander puts on the exoskeleton armor and fights with the robot, this part of the scene can be filmed in VR, allowing the audience to be on the battlefield and experience the strong impact of war. As for how to make the audience wear glasses, it's very simple, remind the audience through subtitles at the beginning of the film, this is a 2D plus VR movie, when the division commander wears an exoskeleton helmet, please also wear VR glasses!"

Wu Erqi slapped his thigh: "The audience saw the division commander wearing a helmet and then wearing VR glasses, which not only solved the problem of when to wear VR glasses, but also made the sense of substitution stronger!"
