"Xinlang Technology Channel? Please sign here, here's the conference sign, and this ......"

The public relations officer at the reception desk handed the badge and envelope to Luo Xiang, pinched the thickness of the envelope, Luo Xiang sighed secretly, two pink tickets. No wonder the editor-in-chief threw this errand to himself, the protagonist of this press conference should not be the famous Mengzhen company, but the illusion company that doesn't know the origin.

Before the meeting started, a group of casually dressed young people were searching for drinks and fruits, and at first glance, they were college students who had not seen much of the world, and the gaze cast at her was also dodgy, making Luo Xiang's heart tumble with two completely different emotions.

There is a strong sense of superiority, although she has only graduated for two or three years, but she is not in contact with this or that O, and these stunned young people are no longer people of the same world. The other is disdain and helplessness, beckoning a group of college students to fill the head, what else can this press conference do? When the time comes, you can only send the press release, and there is no room for your own play.

"Panwang Daguan is becoming more and more like a vegetable market......"

Luo Xiang elegantly held the goblet and glanced at the people coming and going, and let out a sigh of emotion as if standing on the clouds.

There is no video team with us today, and according to the habit of reporters, they should sit on the outermost side of the seats in the first few rows, so that they can take pictures and ask questions. Luo Xiang felt that there was no need to be serious about this press conference, so he shrank to the middle of the back row, ready to nap until the end of the meeting.

It's really nice to have a silk fishing man and a college student on the left and right, which reminds her of her student days a few years ago, and the former school flower has now faded away, and the years are not forgiving. The two little boys who were not yet twenty next to each other kept secretly looking at themselves, and they didn't even dare to say hello, weren't they just pressed to death by their own aura?

Putting on sunglasses, I was about to close my eyes to recuperate, but I saw a pair of young men and women who were also college students holding hands and sitting in the front row. The boy is ordinary, with a bookish face, and a little familiar in a trance. The girl also wears big sunglasses and looks dressed up in Taobao goods, and she is not even as good as her own taste, and she is definitely not a star.

Luo Xiang raised his mobile phone and took a picture, and wrote, "This press conference is no longer a vegetable market but a school cafeteria, and there are all those who show affection", and even sent the photo to a meager one, and continued to nap.

"Sativa engine! It must be the Alfalfa engine! The cactus was only exposed two days ago. ”

"Damn, I've done the automatic molding!"

"Most of it was temporarily rushed out for the press conference, and you can see that there are still a lot of imaginary corners, which have not been completely adjusted."

"Didn't you say it had something to do with Galika? How did you explode such an awesome thing all of a sudden! ”

After falling asleep for about ten minutes, Luo Xiang was woken up by the shouting of the two little boys next to her, and she glared at her in displeasure, only to find that everyone else was staring at the stage tightly.

"There are still some details missing from scanning with the Magic Mirror on your phone, but don't worry, DreamTruth will be further optimized to ensure that the scanning effect meets the needs of general applications. If you need a higher precision effect, Mengzhen will also provide a professional 3D scanning solution to connect to the alfalfa engine, in this regard, Mengzhen has ten years of technical background. ”

On the stage is Zhang Zhicheng, chairman and CEO of Mengzhen Company, who is scanning a car model with his mobile phone, and what first appears on the screen is the 3D model of Mengzhen that everyone is already familiar with, which looks quite rough when magnified several times. The wheels and rounded corners are clearly polygonal, and the undulating areas are also stiff because they are modeled polygonally, and the details of the body are blurred everywhere due to the direct mapping of the captured images.

There was a computer on one side of the podium, and after Zhang Zhicheng finished scanning, he typed the key on the keyboard, and the model began to change. From the rear of the car, the texture disappears one by one, leaving only the outline frame of the model, and clumps of fine particles like sand and gravel are poured into the model, as if by magic, assembling the car piece by piece.

When the picture is enlarged, you can see that each grain of "gravel" is a ball, corresponding to every detail of the car model, with different colors and materials. The screen is zoomed out, and you can see the parts that have been assembled, not only the details are realistic, but the gloss is almost the same as the real model, and the characteristics of metal, plastic, and glass are quite distinct.

What is this......

Seeing a 3D model with close to real details rotating on the screen, Luo Xiang opened his mouth in surprise, is this really a live 3D model? Impossible, how can you model a car in less than ten minutes? This must be a demo video that they have done a long time ago!

"I'm sorry, I thought everyone would bring up a mobile phone or something, but I said a big thing, and I didn't get it done in three minutes."

Zhang Zhicheng apologized, and then handed the car model to the young man on the side of the platform, the young man looked like Luo Xiang's colleague, and when he took the model, he was still shaking his head again and again: "This is impossible, this is simply magic!" ”

It's really on-site scanning and modeling, Luo Xiang regretted it a little, she knew that she shouldn't have taken a nap, and she never let go of this opportunity to brush her face.

Zhang Zhicheng continued: "The ideal of the Dream Mirror is to move reality into the virtual world, but the traditional 3D modeling technology makes the effect of the Dream Mirror not satisfactory, and the Magic Mirror is only used for a rough display so far. For better results, it takes more time and more money. The advent of the Illusion Company's Alfalfa engine gave Mengzhen's ideal a foundation for realization. In the demonstration just now, the Dream True Magic Mirror is just a door, and the magician inside the door is someone else. ”

"On behalf of Mengzhen Company, I am honored to introduce to you the protagonist of today's press conference: Illusion Company! It is the efforts of the illusion company that allow us to make the virtual world more real, please - the general manager of the illusion company in China, Mr. Wu Sihao! ”

An ordinary-looking middle-aged man came to the stage, and he didn't seem to have experienced any big battles, and he was still very restrained.

"He can't do it......"

"I said I would let you go on and you won't do it......"

"You're thinking about showing you my model, open the door! Let me see if you've deleted it! ”

"Even if the file is gone, the memory is still ...... Don't be angry, who made you careless. ”

The little couple in front muttered Luo Xiang's unclear words, a little annoyed.

"Five shrimps! It turns out that he ran the illusion to engage in alfalfa! ”

"Where's Galika? On the cactus, he is the gold medal answerer of Galika, why don't you mention this? ”

"Don't be an old BB, you will definitely say it, otherwise what are we going to do with the Galika testers?"

"Hey, I know what you're thinking, take the magic mirror and scan a girl's paper, and then use alfalfa to make a silicone doll! Don't be so, Lao Kang. ”

The two little boys next to her were nagging words full of hormones, Luo Xiang was slightly dizzy, not smoked, but she vaguely felt that a corner of reality was collapsing, and she hadn't figured out what was going on.

Wu Sihao's explanation is very academic, and the PPT is densely packed with data, graphs and tables, although Luo Xiang has been mixed in the IT circle for two or three years, he still understands seven tricks and six tricks.

Seeing other reporters slamming at the PPT with their mobile phone cameras and tapping on the computer, she glanced at the two little boys and muttered in an obvious voice: "What is so powerful about this alfalfa......"

Sure enough, the little boy who was called "Lao Dao" by his companions came up and explained: "It's very simple, isn't the real world made of molecules and atoms? The alfalfa engine is to set things into particles larger than molecules in virtual space, and then use these particles to assemble things. ”

Luo Xiang pondered for a while before asking, "Didn't that car model just now cost tens of millions or more particles?" Can the hardware get it done? ”

Another one named "Lao Kang" shrugged his shoulders and said, "Isn't this talking? ”

Sure enough, Wu Sihao's PPT on the stage turned a page, and it was something similar to a graphics card.

Lao Dao said excitedly: "Galika! ”

"That's not", Lao Kang corrected: "It's equipped with a CPU, or four ARM, and the architecture should be the same as the afterburner." ”

At this time, Luo Xiang remembered something, Galika, wasn't it the cicada, colleagues have been talking about this thing for the past two days, saying that it is on the bar with Intel and even Moore's Law, and someone bought a piece, and Amway when he sees someone.

Isn't this talking about the Dream True Magic Mirror, what does it have to do with Galika?

What Wu Sihao said next was easy to understand, not only Luo Xiang and the two little boys, but everyone else also listened and watched attentively.

Mengzhen Magic Mirror shows how to use the alfalfa engine to model quickly, and what are the advantages of modeling with the alfalfa engine, and what applications can it have?

The biggest advantage is that the cost of 3D technology has been greatly reduced, and the previous 3D technology has to be modeled with MAYA, 3DMAX or other special tools. Now it's different, with 3D scanners and detail adjustments, you can model quickly and intuitively, without even having to go to a three-month crash course. Of course, if you want to do something that you don't have in reality, you have to pinch it yourself, but it's faster than using those software, after all, the principle is the same as playing with cement.

In addition to talents, the previous 3D production, from modeling, dynamics to rendering, when it comes to anthropomorphic movements, motion capture and even expression capture, not to mention the time, the cost is very high, and it is completely a money-burning business.

When Blizzard did the opening CG of the "World of Warcraft" expansion "Lich King", it spent $20 million in 198 seconds, or $100,000 per second. Now although the technology has progressed, the money is not worth much, the cost still can't be reduced, and the last expansion "Pantheon", the 130-second opening CG, cost 10 million US dollars, or 80,000 US dollars per second.

If you use the Alfalfa engine to do 3D-CG, first of all, you can save most of the time, and the maker can focus on more detailed effect presentation, and the effect will be more realistic than the current CG.

In addition to modeling, another technical innovation of the Alfalfa engine is the elimination of rendering. The biggest piece of time and a big part of the cost of 3D technology is rendering, which is equivalent to assembling and integrating various parts such as models, light and shadow, dynamic effects and special effects, and once the parts go wrong, they have to start over. A two- or three-second shot in a 3D animation can take days or even more than ten days to render. So much so that the industry of render farms was born, which is to use supercomputers to do rendering.

The principle of the Alfalfa engine is to realistically reproduce objects and scenes, and various details and special effects can be directly realized in the scene, so there is no need for rendering.

Wu claims that compared with traditional 3D technology, the Alfalfa engine can save 80 percent of the time and 70 percent of the cost.

In addition to the innovation of time and rendering, the business model of Alfalfa Engine is not simply a license to use, but to build a public general platform, on which people can freely make and trade 3D models, motion, materials and other feature modules, and can develop various detailed functions.

Wu Sihao also introduced that commercial users, such as 3D animation agencies, can completely abandon the previous expensive special effects software, and can no longer spend high rental fees to do rendering, but through the commercial versions provided by Alfalfa for in-depth development, these commercial versions will have more detailed performance in particle, hierarchical modeling and various characteristics.

When it comes to applications, where there is 3D, there is alfalfa.

3D-CG, 3D animation, 3D special effects in the film and television and advertising industry, this is a big piece.

Needless to say, games, in addition to general 3D games, there are also VR games, and using alfalfa to do VR is a match made in heaven.

In the fields of construction, machinery, and even aerospace, the use of alfalfa engines can provide more realistic simulation scenarios, allowing more links in these industries to enter the digital field.

The prospects in the medical industry are also promising, and Alfalfa can create "virtual human" models that are close to the molecular level, providing more powerful digital tools for medicine. For example, using this virtual human model, coupled with VR technology, can allow medical schools to conduct simulated surgery training, and even conduct simulation drills before real surgery.

This item was thrown out, and the venue remained silent, and most people were shocked to the point of being stupid, which is subverting the entire 3D industry! It's really ...... to do 3D animations at a third of the cost and one-fifth of the time it used to be

"Great!"

This is the voice of people who do CG or animation and film and television special effects.

"Do you want anyone to live!"

That's the voice of people who sell 3D software, servers, and live on traditional 3D technology.

The silence continued, and Luo Xiang finally couldn't help but stand up and wake everyone up with a word: "The alfalfa engine sounds really good, but can the hardware achieve it?" The car model just now, calculated that there are at least hundreds of millions of particles, even the server can't complete such a large amount of calculations, right? ”

Asking questions before the question session was very ruinous, but after this question, others also echoed it, and soon gathered into a wave.

"It's too much...... Hehe......"

Luo Xiang's face was flushed, he was proud of the wave of questioning he had raised, and he was proud of the question that hit the door, this face was good! After going back, the editor-in-chief will definitely praise himself for raising the face of the channel!

The two little boys next to her looked at her and muttered again.

"Lao Wu still found a trust?"

"I couldn't see it just now......"

The boy in the front row looked back at her and gave her a thumbs up, which made Luo Xiang's feeling of stepping on the clouds even stronger.

On the stage, Wu Sihao smiled and nodded: "This question is very good!" As for the number of particles in the car model just now, there are actually more than 10 billion ......."

Everyone was stunned, and Luo Xiang's face turned even redder, what happened if he was not good at math? You can deny it by this!

Then Wu Sihao admitted Luo Xiang's statement: "Although the existing hardware can also be realized, it is obviously uneconomical and impractical. ”

Before everyone was clamoring, Luo Xiang asked, and Wu Sihao said: "This is what I'm going to talk about next, the hardware part of Alfalfa, I'm sorry, the PPT has been turned here, I was off topic just now." ”

The venue is quiet again, and countless people are complaining, if you deviate from the topic, you will kill a trader!

Attention turned back to the PPT, looking at the similar graphics card, everyone was puzzled, and after a long time, Alfalfa is not a software, but a complete set of software and hardware.

So what is this "Alfalfa Card"?
