The Return of the Black Technology of Immortal World

But watching these things with a VR headset does not show the advantages of VR at all. They are completely flat displays without a three-dimensional effect. monitor.

Therefore, to get the right effect, you need movies and games specially optimized for VR.

Different from ordinary blockbusters, ordinary blockbusters are shot with multiple cameras. When watching movies, stereoscopic glasses are used to obtain a part of the three-dimensional effect. Feel.

However, VR movies use 360-degree surround shooting and surround-type stereo sound effects, so it will give people an immersive experience. When watching movies, you can turn your head at will to find different pictures. , It is similar to the effect of people living in nature, so this is called immersive experience.

Moreover, in VR movies, people can also participate in real time, not only as spectators, but also as a participant in the movie, making choices for the characters in every crucial choice. , It is almost the same as VR games, and this has become the fusion of movies and games.

However, due to the extremely high bit rate of VR movies, almost only Gigabit broadband can meet the requirements for real-time playback of VR movies. Therefore, in general, downloading them directly to the computer and playing them locally can meet the playback requirements of VR movies.

However, after Xiao Ai downloads the movie, there are other advantages, that is, the VR movie can be compressed to a very small size, so that an ordinary 10M broadband can easily meet the playback requirements of several VR movies.

At the same time, it also brings opportunities for VR games that can be connected to the Internet in the future. VR games are very different from other online games. The biggest difference is the size of the data. It only needs to transmit a few dozen frames of pictures in the game, but it needs to transmit hundreds of frames of pictures in VR, so as to meet the basic picture requirements. Therefore, this type of game has a very high demand for network bandwidth. If the customer If the terminal Gigabit network can meet the demand, then the bandwidth of the server is at least several hundred times that.

Yes, the vast majority of VR games nowadays are actually stand-alone games. The so-called networking function is to add a leaderboard, rather than the large-scale virtual reality online games described in Spielberg's movies.

But if the super compression technology is applied, the bandwidth required by VR games will be reduced by hundreds of times in an instant, and it can basically be transmitted in real time on the network.

In fact, super-compression technology is also good for traditional online games, that is, with the reduction of bandwidth pressure, one server per country, or even one server for all games is no longer a dream.

Of course, this has higher requirements on the server, but compared to the more attractive idea of ​​the same server all over the world, the pressure on the server is much easier to overcome.

Why! Now we are waiting for when Weihua can test the super compression technology well, or when they can finally retreat from the difficulties and stop trying to crack the programs in the USB flash drive.

They retreated in the face of difficulties, so they came to negotiate with themselves as soon as possible, so that they could launch the super compression technology as soon as possible.

After all, without the support of super compression technology, even if Yang Qing develops a VR game, it can only become a stand-alone game instead of the envisioned online game.

After watching "Artificial Intelligence: The New Awakening" downloaded by Xiaomei for a while, this VR movie produced by Pig Farm, although this VR movie was only shot at 180 degrees, it cannot fully show the characteristics of VR. But that God-like vision has fully demonstrated the characteristics of VR.

It is also here that Yang Qing found the VR headset, or the biggest flaw of the VR headset at this price is that with the swing of the head, the movie screen does not rotate smoothly, and there is no smooth switching between the human eye and the outside world at all. .

If this kind of picture is only fixed in one direction, there is no problem, but in order to achieve the effect of VR, the sensor on the VR head display will adjust the picture every time the head shakes. The sluggishness is actually not obvious, otherwise this kind of VR headset would not be necessary to go on the market at all, but after a long time, with Yang Qing's endurance, he would feel dizzy, of course, this is also related to his amazing eyesight, The reason why the **** of every movement feels more powerful.

According to Yang Qing’s estimation, ordinary people with this kind of VR head-mounted display should feel dizzy like motion sickness after watching a movie for about an hour. However, most of the VR movies on the market are ten to tens of minutes long Short videos, so this VR headset is still barely usable.

However, it is a bit difficult to play games. After all, games are fast-paced dynamic images, which will cause more discomfort.

Fortunately, the current VR games are relatively simple, with strong color contrast, and can be played for a while. When there are games like 3A masterpieces in the future, they will have no chance at all.

After watching the movie for a while, Yang Qing switched to newly downloaded games, such as "Half-Life: Alix~www.wuxiahere.com~ and of course the famous "Beatsaber (Rhythm Lightsaber, which are all on the steam platform Xiao Ai spent money to buy the top-ranked VR games in order to refer to their writing methods and data structures, and let Yang Qing experience them by the way.

Sure enough, a VR headset worth about 1,000 yuan is not suitable for playing games before it has been modified. With the attached peripherals, Yang Qing had to quit the game after playing for less than five minutes. It can be seen how much improvement this VR headset will have after Xiao Ai updates the driver without changing the hardware.

Xiao Ai's movements have always been very fast. During Yang Qing's trial of VR, she had already figured out the firmware and sensors on the VR device, and by the way, programmed a small operating system.

In fact, if so many auxiliary functions are not needed, the operating system can be made very small. The operating system of Xiao Ai is only 1MB in size, but it perfectly integrates a series of functions such as screen display and sensor control.

Learning from the lesson Yang Qing asked her to rework last time, Xiao Ai did not use machine language to write the operating system this time, but a mixture of C++ and assembly. After compression, it became an operating system with only 1MB.

Of course, the size of the operating system is not important. Even if it is much larger, the memory with increasing storage capacity can still accommodate it. The most important thing is that Xiao Ai also placed a small clone in it, which is responsible for calling computer resources. Interpolation calculates the picture, increases the number of colors of the head display screen, so that the grainy feeling caused by the low resolution will not appear on the picture, and controls the sensor and picture to make the picture as smooth as possible, so that watching movies or When playing games, there will be no feeling of dizziness.
