"The eldest son, the above information only tells the general principle, and there are many subdivision principle steps in the real operation. At present, the most used in the industry and the most potential is the computer holographic display image, referred to as CGH, which mainly uses the computer to perform complex calculations to directly generate a holographic display image and then carry out holographic projection. ”

"This technique is mainly used to simulate various objects that do not exist in reality, so it is easy and flexible to use. For example, various virtual characters and objects in games or animations are directly generated by the computer, or directly generated according to the made characters, prop models, etc., a holographic display picture, and can display all the angles of the model on a negative, and various postures and movements, etc., and then use holographic projection technology to display specific virtual images on the projection film or holographic board. ”

In reality, whether it is a person, an object, or a variety of carved physical models, etc., it is necessary to first collect and record the overall origin amplitude fluctuation and spatial phase (position) of the object, and then restore it through the computer, and then display it with holographic projection technology and professional 3D projection equipment. This involves the organic combination of optics and electronics, which can give full play to the respective advantages of both parties, which is a necessary stage for further research and mastery of real holographic image technology. ”

"In recent years, our top ten groups have broken through this technology and overcome several related core technologies, which is why today's holographic three-dimensional map of the earth has appeared. When you first open the map, it may look like it's colorful, but that's just to add a sense of ritual, otherwise it's just a hidden invisible laser beam that displays it holographically in three dimensions. "The Heavenly System said.

"By the way, I had a general understanding of the transitional 3D technologies. I'm going to talk about my simple understanding, and you see if there's anything wrong. The little fish said to the Tongtian system.

"Okay, eldest prince, please speak up. "The Tongtian system replied.

"In my understanding, VR refers to virtual reality technology, which is the direct generation of a new, completely virtual world through professional equipment, in which you can do anything, create anything, or make various rules. The future online virtual reality game is a typical kind of VR technology based on creation. You only need to wear a professional helmet or lie down in the nutrition compartment, etc., and you can directly enter the virtual online game world. ”

"As for AR, MR and other technologies, AR refers to augmented reality, which is a virtual image that enhances the display of something in reality. MR mixed reality technology is an upgraded version of AR, which can also be called a new technology that combines the advantages of VR and AR. ”

"In recent years, MR technology has been widely used, but some people still can't tell the difference between AR and MR. In fact, what they all have in common is that they need to use professional 3D eyes to see those virtual characters, characters, props, etc. that have already been set up in the system. ”

"For example, in recent years, Microsoft Group, a well-known Internet software technology giant in the United States, still has some technical content in the research of MR mixed reality. Microsoft's latest second-generation MR display product is HoloLens2, and the display effect may be just a child's toy for the current Tongtian Group. But our top 10 groups are in a period of secrecy, and they are the only MR on the market at the moment, and it is said that a single HoloLens2 will cost thousands of dollars. In the territory of Huaxia, due to various additional expenses, the price is about 30,000 or 40,000 Huaxia coins. ”

"As for whether there are other hidden research laboratories, consortium research institutes, etc., that technology, it is unknown, after all, we will not be bored to find out other people's secrets, and it is estimated that no matter how much research and development is not as advanced as the top ten groups. But for the average person, the purchase value of Microsoft HoloLens2 is not much, it is not a necessity. Most of its buyers are young people who like new technologies, enthusiasts, or professional users such as governments, companies and enterprises. I recently heard that their third-generation product, HoloLens3, could be released in the next two years. ”

"To get back to the point, the difference between AR and MR is actually very simple, simply put, AR virtual characters, props, objects, etc., cannot interact with real objects in the surrounding environment, and MR technology can do this. ”

"Because all the characters, props, objects, etc. displayed by AR technology are based on the surface of real objects, real objects have no effect on it. When you turn your head and move your AR eyes, the avatar will move with you, or at most you will still be standing in place, rather than moving from where you are. ”

For example, if you play a game with Microsoft's HoloLens2, the characters in the game can walk back and forth in your home, or sit on the bed, sofa, chair and chat with you, etc. Or if you have a virtual ball in your hand and you throw it forward, if it hits a wall or a table, it will be blocked by these real-life objects like a real ball, or it will stop moving forward, or it will bounce and jump somewhere else. ”

"In this case, it is not possible with AR technology, and the virtual characters and objects displayed can also move, but they can only interact with the viewer himself. The virtual characters, animals, etc. you see on the AR eyes only interact with you, and they don't take into account the changes in the environment during the week, in other words, they ignore the real objects around them. ”

"Tongtian, the above is my understanding of those 3D imaging technologies after consulting the relevant information, do you see any misunderstandings?" Worry-free Chinese network

"My lord, your understanding of VR, AR, and MR 3D technologies is still relatively complete. But in the end, human beings will have to develop towards hologram technology, because this technology is the technology that human beings will often use in the future, and it is also very practical. ”

"Holographic projection technology will be widely used in the future, such as in the field of medical treatment, education, exploration of interstellar objects in outer space, unknown regions of the earth, unknown creatures, deep-sea exploration and other fields... This technique will be used. ”

"In the future, when the brain-computer interconnection technology matures, the human brain will directly attach to the outer skin of the head, or implant a special human-computer interconnection chip inside the brain, or directly link the surrounding electromagnetic waves with its own mental power without any physical tools, and then control many networked technology devices around it, regardless of whether it belongs to the category of artificial intelligence. ”

In this way, in the future, human beings can interact with virtual humans or virtual objects formed by holographic image technology anytime and anywhere. This is the right way to open hologram technology in the future, and it is also one of the common scenarios in the future. Tongtian System said.

"As for the cutting-edge science and technology research institutes of some developed countries overseas, what they are studying is to open an opening in the human head, and then plug in a wire for brain-computer interconnection. This technical conjecture, after the discussion and demonstration of the relevant research group of the group, found that although this technology is feasible, it is not suitable for regular use. Similarly, most people can't accept that they can make a hole in their head and plug it in wherever they go, which is too unfree, and this can only be used in some special cases. ”

"Of course, you can open a flat square opening in the head and put the man-machine chip into it, just like the current mobile phone card, and you can also carry out human-machine interconnection. In this way, in the future, when humans enter the virtual reality online game and travel to the virtual world, they may not need to wear a special helmet or lie in the nutrition warehouse as humans guess, but directly enter the virtual game world through the chip implanted in the brain. If you are a person with strong mental power, you may be able to upload your own brainwave unique band in the game system, and then get approval, and then directly enter the virtual game world. Tongtian System said again.

"Well, that's a possibility in the future. The fish narrowed.

"By the way, I have a guess about hologram technology, you can analyze whether it is feasible. ”

"Son, please. Tongtian System said.

"Quite simply, after the maturity of artificial intelligence and robotics, coupled with mature holographic image technology, combined with more advanced 6G technology, can we create a suspended aircraft that can imitate any person, object, animal, including aquatic creatures and plants, just like today's drones. ”

In this way, people will sometimes find that some of the objects and animals they see are actually virtual images displayed by the aircraft using holographic image technology to project a laser beam of appropriate radius to the surroundings. The surface looks too real to be distinguished to the naked eye, but inside it is just a small and medium-sized aircraft for projecting holograms. In this way, wouldn't it be applied to many fields of exploration?"

"My lord, this creative idea of yours is very good. According to the group's current technical reserves, the technical problems faced are mainly laser short-range radial projection technology, and other technologies are not difficult. However, judging from the group's R&D speed, this technology is not a problem, but it takes a certain amount of time to study and solve. "The Tongtian system replied.

In this way, hologram technology can be flexibly applied in many ways, such as military use, exploration, field monitoring, unknown environments, geographical exploration... Wait, well, that's a good thing!" the fish nodded unconsciously.

Xiao Xiaoyu looked at the extremely real three-dimensional hologram of the earth in front of him, and couldn't help but sigh with emotion: "The scenes in science fiction and movies in the past can really be seen with your own eyes today, and time is like flowing water, passing in the blink of an eye." ”

"Of course, the future three-dimensional digital map, which covers the range of space from the center of the earth to the space region, is a kind of spatial three-dimensional network map that can be accurate to the decimeter level. In the future, there will even be a holographic three-dimensional space map that includes the entire solar system, which can be called the most primitive interstellar map. ”

Zhou Dao on the side didn't know when he abandoned the king's mobile game, and answered at this time.
