The "d" in "3D" is the first letter of English (linearity, dimension), and 3D refers to three-dimensional space. Internationally, 3D movies are used to represent stereoscopic films.

The principle of 3D cinema comes from the different visual angles of the left and right eyes of the human eye - the image of the scenery is different from the left and right eyes.

It uses two side-by-side cinema cameras, representing the left and right eyes of the human eye, to simultaneously shoot two cinematic images with slight horizontal parallax. During the projection, the two movie clips are loaded into the left and right movie projectors. When the picture is projected in front of the movie screen, a "subtle" double image of the left and right is formed.

The special polarized glasses can superimpose the left and right "double shadows" on the retina, and produce a three-dimensional visual effect from the brain nerves, thus showing a coherent three-dimensional picture, allowing the audience to feel the magical illusion of "immersive" scenery.

In fact, the market exploration of 3D stereoscopic films began as early as the 80s of the last century, when it was mainly based on horror films, such as "Friday the 13th", "Devil Cry 3", "Jaws 3D", and the audience seemed to be more willing to accept the horror atmosphere with enhanced three-dimensional sense.

However, its shortcomings are quite obvious, at that time digital technology did not develop, a set of cameras weighed thirty or forty pounds, and in the digital age, 3D cameras have been less than 10 pounds. At the time of projection, the previous film 3D film had to be played on two projectors at the same time, and the slightest out-of-sync film was ruined.

This kind of 3D film was soon forgotten by the market, and filmmakers were no longer enthusiastic about 3D stereoscopic films, which were technically difficult, so throughout the 90s of the last century, stereoscopic live-action films did not have any major productions.

However, in the 21st century, film technology has developed by leaps and bounds, and many technologies have begun to support 3D shooting.

Just last year, that is, in 2007, Wang Shang began to pay part of his attention to the field of 3D technology research and development.

Wang Shang knows that "Avatar", which became the king of the world box office in the former time and space and promoted the 3D craze to the world, has been preparing since 2007. Wang Shang is in this time and space. I also started to pay attention to the information of this movie early on.

Fortunately, Wang Shang did not see any news about "Avatar" in this time and space ("Avatar" was created by Cameron in 1995 in the previous plane), presumably harmonized by the butterfly effect, when James Cameron was directing another movie.

However, Wang Shang is still a little vigilant, 3D technology should almost be able to come out, and if it doesn't come out, this head will be occupied by others.

Part of the reason why "Avatar" could harvest so much horror box office at that time was the gimmick of 3D.

China in this time and space is quite powerful, although there is a slight gap between the technology and industrial level and the United States. But not very far.

Since then (2007). Wang Shang invited hundreds of experts to form a 3D research team. Research and development of cameras, projectors, audio equipment, and operation processing systems.

During this period, dozens of foreign leading technology equipment were dismantled, and the cost was as high as more than one billion.

However, these are secondary, and the most important thing is that Wang Shang provided the key technology for this. Wang Shang uses the network in his mind to link the former space-time, and at this time, the former space-time has begun to develop into 2020. The technology of 3D is also developing rapidly. A lot of outdated technical data has also begun to be cracked and published. However, these expired technical materials have been obtained from the current time and space that has lagged behind for more than ten years, which is advanced enough.

Last year, when Wang Shang sent out an invitation to develop 3D technology, all the invited experts couldn't help but be shocked by Wang Shang's idea. However, when Wang Shang gave them some information, they began to become ecstatic, and they began to join the R&D team obediently.

In the outside world, many people know this R&D team. But I don't know what this R&D team does, it has always been mysterious, and even almost all the employees of Tianwang Film and Television Company don't know, and only Wang Shang and General Manager Bi Han know about it.

However, General Manager Bihan does not pay much attention to this part at present, and sometimes he is still depressed that the company has invested in special effects. There is another huge black hole of capital consumption.

Now that it has just arrived on Chinese New Year's Eve, such good news has come, how can Wang Shang not be overjoyed?

"Good!! That's great!! ”

The next day, Wang Shang couldn't wait to get on the plane to Yanjing, and arrived at a building near Mizuki University at noon that day. The R&D headquarters is here, and Wang Shang specially bought 3 floors here for research. I saw that the entire 3 floors were divided into pieces by glass, and there were a variety of green plants inside, which was super amazing at a glance, so that people could still feel the breath of nature after work.

Soon Wang Shang met the head of the research team, Liang Zhenyu, a professor at Mizuki University, a veteran researcher in his sixties. He was wearing glasses that resembled the bottom of a beer bottle, directing a young researcher to debug a computer.

After seeing Wang Shang coming, he became happy, and pulled Wang Shang straight to a laboratory.

"The camera and projector were developed two months ago according to the information you gave, and although there were a lot of problems in the middle, we were able to overcome them. However, at first, after the image was projected, I felt uncomfortable, but when I finally checked it, I found that there was a problem with both the polarizer and the processing system. ”

"Now that's finally it!!" Professor Leung couldn't help but feel very excited.

Wang Shang looked at the two machines in front of him with a whole data cable falling off the ground, looking strange and unaesthetic, and asked, "These two are cameras and projectors??" ”

Very bulky, especially for projectors. However, this is crude after all, and it needs to be further developed.

Professor Liang nodded, and introduced: "According to the technical information given by Mr. Wang, as well as foreign machine materials, this digital camera was made, which has two high-definition digital camera lenses, so that the 3D film picture has increased from two levels in the past to four levels, and has a sense of spatial hierarchy. ”

"We call it a 3D camera ......"

"Cameras? Good ......" Wang Shang praised it, because this name robbed the name of the camera developed by Cameron for the filming of "Avatar".

Soon Wang Shang put on polarized eyes and began to watch the finished film. This 3D film is a short film, and the content is a wild scene, with grass, trees, and small animals, all shot up close. Wang Shang can see and feel the obvious 3D stereoscopic effect in the process of watching, but ...... There are a lot of disadvantages.

The brightness is not high: if you shoot a night scene, it is estimated that it will look dark......

The resolution is not enough, compared to the projection results of the 1.5K projector in the previous life, the image projected on the screen is slightly blurred, there is no way to form a good visual sense, as if watching an old movie in the eighties, this is only on a small movie screen, if you go to the cinema The two-storey high large screen, it is estimated that it will be a splash directly......

Professor Liang probably understood Wang Shang's feelings, and explained: "There should be no problem with the camera projector or something, the key should be that the processing system is not done well, if the system is updated and improved, the effect should be greatly improved." ”

Wang Shang nodded, agreeing with his statement, a good system can make the technology better. Just like a computer operating system, a good operating system will be better than a bad operating system in terms of security and processing power, which can make the computer more powerful.

However, after only a few months, it was enough to surprise Wang Shang with such results.

"You guys should hurry up and study it, and I'll think of a way to do it here."

Wang Shang finally allocated 50 million reward funds to the whole team.

Before leaving, Wang Shang made another request: "By the way, if you can, open another project - update the technology of expression capture and motion capture." It is best to attach 95% of the information of the expressions and movements of the live performance to the virtual characters (CG characters) generated by computer animation, so that they have a high sense of reality. If there is a shortage of people, you can recruit as long as you sign a confidentiality agreement. ”

Because of the expansion of 3D technology, Wang Shang is also very happy this Spring Festival. However, in addition to the Chinese New Year, I am also paying attention to the Internet in my head that links to the previous time and space, and trying to find out if there is any relevant operating system technical information.

In addition to this, Wang Shang is also thinking about which film should be shot if the 3D photography technology is mature.

Is it Avatar?

Or Transformers?

Or is it something else?

"If you shoot "Avatar", it will take a little longer, and although all kinds of preparations have been done, the production time of more than a year and a half is absolutely indispensable."

"The basic script of "Transformers" is already available, and it only needs to be revised to form a 3D shooting script."

"There is also "The Matrix", I have always wanted to shoot it, but I haven't started filming it yet."

"Or Pirates of the Caribbean isn't bad......"

Wang Shang thought about it and found that there were quite a lot of movies he could choose. As for the TV series, the original plan could only be put on hold temporarily because of the appearance of 3D.

Just when Wang Shang was suffering and happy because he had too many choices, suddenly news came from abroad that made Wang Shang extremely nervous and extremely painful.

Warner and Paramount jointly announced that the two film companies will work together to produce "The Lord of the Rings 1 - The Lord of the Rings Reappear", which is known as the ancestor of magic, and the director is to shoot "Titanic" James Brown. Cameron.

"Oh my God!!"

Wang Shang can be said to be dumbfounded: "Cameron actually took over "The Lord of the Rings"?? ”

However, what made Wang Shang even more stunned was still to come, "The Lord of the Rings" was announced to shoot 3D directly!!

Wang Shang: "......"

The world is in complete chaos.

Today, I'm basically checking the information, and I'm ......
