The bone of sin domain is king

Chapter 300 No.11 Scene. Photography Technique

Wait, make a projection function?
Grantia froze.

Are you kidding me?
This was her first reaction.

As a spell above the fifth level, projection magic would be 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 replication of reality, turning the real scene into the flow of magic power. Different objects correspond to different ways of magic power flow, which requires quite delicate operations.

The second link is the storage of magic power, which keeps the magic power copied from reality unscathed, and carries it through things such as magic power crystals.

The third is reappearance, transforming the original magic power into a visible scene, which is exactly the opposite of the first link, but it also requires precise magic power control.

In fact, most of the projection magic that people can come into contact with in life has been simplified to some extent, using props made by alchemy to realize the first or third link with other means, reducing the requirements for use Otherwise, this spell will still be shelved.

And this [Ash without fire] actually said that it will make a projection function?
It's not arrogance, it's closer to stupidity.

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

[The ashes of no fire: The so-called projection magic is just a combination of several basic magics. For a mage apprentice like you, it is of course a high-level magic that is out of reach, but in the final analysis, it is a little more complicated. That's all. 】

When Grandia saw this sentence, the corner of her mouth couldn't help twitching.

This guy seemed to be quite confident in his own strength. In his mouth, the fifth-level magic was only "a little bit more complicated."

However, someone who can develop something as powerful as a mobile terminal will not be far behind anyway.

[Ultramarine Fortress Scholar: Please wait a moment. Although projection magic may be a very simple and basic spell for you, you have to know that the so-called magic competition can only be entered by magic that I can reproduce, with the help of other people. Or the behavior of powerful magic weapon is against the regulations and will be disqualified! 】

Even though this [Fireless Ashes] is powerful enough to completely deconstruct projection magic, that complex spell is simply not something a mage apprentice of Grandia's level can control. If it cannot be used on the spot, then Everything is in vain.

[Fireless ashes: Of course I know about this kind of thing, but since when did you have the illusion that I want to teach you to use projection magic? 】

Seeing the other party's words, Grandia was stunned for a moment, and a strange idea emerged in her mind.

This guy, could it be that he has developed something else that can replace projection magic?

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

[The ashes of no fire: Listen, what I'm going to show you next is not some old-fashioned projection magic, but a real photography technique. 】

"how did you do that?"

Lisa was a little curious. Although the thing called "camera" in front of her contained an extremely complicated magic circle, it was significantly different from traditional projection magic. Guide.

"It's very simple. The projection magic in the past actually captures all the elements and the flow of magic power, and constructs a completely dynamic picture. This kind of picture has a high degree of restoration, but there is also a drawback, that is, it is difficult for transmission accuracy and collection. The requirements for mana control during the image are quite high, which is one of the reasons why it is a fifth-order magic."

Rosen waved his hand lightly, and a picture made of blue runes appeared in midair, which was the projection of the mobile terminal.

"But this approach, simply put, is not friendly to the people."

Since the projection magic was originally intended to completely reproduce the scene at that time, subtle changes such as the flow of magic power will be included in it, resulting in quite complicated.

When Rosen developed this photography technology, he discarded most of the redundant data and only collected the most basic things that can be captured by normal people's vision.

"After exposure, that is, when the photosensitive array accepts external images, what I use is not a continuous and smooth image, but a separate point, each point records its position and color, this discrete The amount is actually easier to store than flowing magic."

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

Using the Siegel transform, which is the Fourier transform of this world, converts all continuous quantities into discrete quantities, and stores them in the crystal in the form of pixels, which solves the problem of projection magic's high requirements for magic power control accuracy in one fell swoop. The disadvantage of difficult storage.

And it is quite simple to play it out, as long as the Siegel inverse transformation is performed to convert the discrete quantity into a continuous quantity again.

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

As Rosen said, he took the camera back from Lisa's hand, then lightly started it, and after a while, Lisa's appearance was captured in the crystal.

"It can be connected to a mobile terminal to upload photos directly to forum posts or personal space. It can also be projected directly into mid-air like projection magic."

At one point, a picture of Lisa appeared in mid-air. It didn't look much different from the real Lisa. If you didn't use magic power to detect it, it would be the same as the picture shown by 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 a camera with advanced configuration, and the picture quality will be much worse. This one is the full version of the camera, and the picture accuracy is about More than a thousand times that of mobile terminals.”

According to Rosen’s experience in his previous life, even though mobile phones have taken over people’s lives, cameras will not stop there. This is a professional need.

In fact, this camera also has the ability to expand. If necessary, it can also engrave the entire array of projection magic into it, making it a real projection magic camera. Of course, correspondingly, a certain amount of magic power is required to activate it. just work.

However, for Grandia's next magic competition, Rosen thought that being able to take out this camera would be enough to crush other people.
