Wait, make a projection function?

Are you kidding?

That was her first reaction.

As a spell above the fifth order, projection magic is difficult for a low-level mage to do without the assistance of powerful props, because this spell is actually divided into three links.

The first link is the reproduction of reality, which turns the scene of reality into the flow of magic, and different objects correspond to different ways of magic flow, which requires quite delicate operations.

The second link is the storage of mana, where the mana that copies reality is preserved unscathed and carried through things like mana crystals.

The third is reproduction, which transforms the original magic into a visible vision, which is the opposite of the first link, but also requires precise magic control.

In fact, most of the projection magic that can be accessed in people's lives has been simplified to some extent, using the props made of alchemy, and the first or third link is realized by other means, reducing the use requirements, otherwise, this spell is still shelved.

And this [fireless ashes] actually said that it wanted to make a projection function?

This is no longer arrogant and closer to the level of stupidity.

Perhaps sensing the other party's incomprehension from the delay in Grantia's reply, the other party sent another message to explain.

[Ashes without fire: The so-called projection magic is just a combination of several basic magics, and for a mage apprentice like you, of course, it is unattainable high-level magic, but in the final analysis, it is just a little more complicated. 】

When Grantia saw this, the corners of her mouth couldn't help twitching.

This guy seemed to be quite confident in his own strength, and the fifth-order magic in his mouth was only "a little more complicated", and Grandia was suddenly a little curious about what kind of existence was on the other side.

However, people who can develop something as powerful as a mobile terminal will not be far behind in any way.

[Ultramarine Fortress Scholar: Wait a minute, although projection magic may be a fairly simple and basic spell for you, you must know that the so-called magic competition can only be participated in by me with magic that can be reproduced, and the use of other people or powerful magic guides is against the rules and will be disqualified!]

Even if this [Fireless Ash] was powerful enough to completely deconstruct projection magic, the complex spell was simply not something that a mage apprentice of Grantia's level could control, and if it couldn't be used on the spot, then it would be all in vain.

[Fireless Aftermath: Of course I know about this, but when did you come to know that I want to teach you the illusion of using projection magic?]

Seeing the other party's words, Grantia was stunned, and a strange thought came to her mind.

Could it be that this guy has developed something else that can replace projection magic?

Soon, the other party's reply told Grantia the real answer.

[Aftermath without fire: Listen, I'm going to show you that it's not some old-fashioned projection magic, but a real photographic technique.] 】

......

"How is this done?"

Lisa was a little curious, the thing in front of her called "camera", although it contained an extremely complex magic array, it was significantly different from traditional projection magic, and it was obviously not the magic guide that replaced one of the stages of projection magic in the past.

"It's very simple, the projection magic of the past is actually to capture all the elements and magic flow, and build a completely dynamic picture, which has a high degree of picture restoration, but there is also a drawback, that is, the requirements for transmission accuracy and magic control when collecting images are quite high, which is one of the reasons why it is a fifth-order magic. ”

With a slight wave of his hand, a picture of dark blue runes appeared in mid-air, which was a projection of a mobile terminal.

"But this approach, to put it simply, is not close to the people. ”

Since the projection magic was originally intended to completely recreate the scene at the time, subtle changes such as the flow of magic were included, which made it quite complicated.

In developing this photographic technology, Lawson discarded most of the redundant data and collected only the most basic things that could be captured with the vision of a normal person.

"When I was exposed, that is, when I made the array receive images from the outside world, I didn't use a continuous smooth image, but separate dots, each of which recorded its position and color, and this discrete quantity was actually easier to store than the magic of flow. ”

So the first step of Rosen's camera is to discretize continuous reality.

Using the Siegel transform, which is the Fourier transform of this world, all continuous quantities are converted into discrete quantities and stored in crystals in the mode of pixels, which solves the shortcomings of projection magic with excessive requirements for magic control accuracy and difficult storage in one fell swoop.

And if you want to play it, it's quite simple, just do the Siegel inverse transformation and turn the discrete quantity back into a continuous quantity.

"But the image made in this way is not actually a completely real image, it can only be called a virtual image that can be observed by the naked eye, and the distribution of elements and the flow of magic in it cannot be reflected at all, but for ordinary people, these are unnecessary. ”

As he spoke, Lawson retrieved the camera from Lisa's hand, activated it gently, and after a few moments, captured Lisa's appearance in the crystal.

"It can be connected to a mobile terminal, and photos can be uploaded directly to forum posts or personal spaces, or it can be projected directly into mid-air like projection magic. ”

At one point, Lisa's image appeared in mid-air, which looked not much different from the real Lisa, and if it was not detected by magic, then it would be no different from the picture shown by the projection magic.

"All the functions of this camera are built into the mobile terminal, but due to the limited capacity of the crystal, I did not use the camera with advanced configuration, and the picture quality will be much worse, and this one, the full version of the camera, the picture accuracy is about 1,000 times more than that of the mobile terminal. ”

According to Rosen's experience in the previous life, even if mobile phones occupy people's lives, cameras will not stop there, which is a professional need.

In fact, this camera also has the ability to expand, and if needed, it can also engrave the entire circle of projection magic, making it a real projection magic camera, and of course, correspondingly, a certain amount of magic power is required to activate.

However, for Grantia's next magic competition, Rosen thinks that taking out this camera will be enough to crush the others.
