Metaverse Evolution

Chu Fei observed for a moment and found the "General Outline of the Wind of Perception".

First, turn to the table of contents, which is divided into five parts.

First, introduce the life basis of magic and what is the "wind of perception";

Second, it is the scientific theory and technology required for the wind of perception;

Third, it is the means of detection and data collection;

Finally, establish a thinking model to restore the data to a "picture" that the brain can understand.

Finally, when the wind of perception is familiar enough and the personal practice is strong enough, the data can be read directly without the need to "restore the picture".

The last point is easy to understand. As we all know, servers use character interfaces, and home computers pay attention to graphical interfaces.

After reading the table of contents, Chu Fei opened the prologue.

The prologue mainly introduces the life basis of magic.

Life itself is a miracle, a magic.

Self-will, observer effect, thought driving the body...

All of this can be explained by scientific ideas or by magic ideas.

And the magic and practice of some fantasy civilizations in the universe are just developed on this basis.

Since other civilizations can do it, we as scientific civilizations can also do it, and do it better.

After all, there is an essential difference between fantasy civilization and scientific civilization.

The development model of fantasy civilization is similar to the situation of ancient earth civilization - summarizing experience in long production, and then solidifying experience into technology, with a long time span, low efficiency, great differences, no unified standards, factional divisions, etc.

To sum up: start with the phenomenon.

However, scientific civilization directly derives the foundation from scientific theory and starts directly from the essence.

Therefore, fantasy civilization pursues ascension, becoming a god, and immortality, while scientific civilization directly expresses - I want to become a pure data life.

After reading the preface, Chu Fei was thoughtful.

Click on a virtual box above the book, and then the whole book turns into a data stream and is quickly written into Chu Fei's consciousness.

This kind of reading is very efficient, but it also puts a lot of pressure on the brain and the spirit.

In just one minute, the content of the whole book has been completely written into Chu Fei's mind.

A few minutes later, Chu Fei slowly opened his eyes.

"So that's it!"

Then, Chu Fei turned his head and walked to a virtual box and clicked "Simulation Experience".

Scientific practice must have scientific characteristics.

Just as people know the temperature of water after drinking it, magic can only be understood more deeply after experiencing it by themselves. And virtual technology can meet this requirement.

The next moment, Chu Fei appeared in front of a huge rock.

Lines of information emerged from his eyes, introducing the current "simulation situation" - through active sound, echo, sound refraction, diffraction, etc., using calculation methods to obtain "three-dimensional points".

When a large amount of three-dimensional point data is obtained, an abstract three-dimensional picture is restored through modeling.

Then the image is repaired by rendering, and finally a relatively blurred picture is obtained.

Compared with the rock in front of him, this picture has a similar general framework, but no details.

But compared with the eyes, the wind of perception can "see" the back of the rock!

The line of sight cannot turn, but the sound can.

Then the second simulation began.

Chu Fei's eyes went dark and he could not see the picture at all.

This time, Chu Fei only took the initiative to speak, and the computer was responsible for calculation to restore a three-dimensional picture.

After the calculation, the vision was restored.

Chu Fei proofread the result. The general outline is fine, but the details are still blurry.

Then a new simulation started.

This time, "line" scanning and "surface" scanning simulation were used.

Compared with point scanning, line and surface scanning methods are faster and require higher calculations, but the image is still blurry.

At the same time, in order to better capture the sound, the hearing gene must be turned on-this is the ability of the awakened.

Then the three points, lines and surfaces were combined, and the computer ran more than a dozen computing threads at the same time. It took only a moment to calculate the shape of the rocks, which was also clearer.

Chu Fei looked carefully and found that clarity was relative. The perception of the wind relies on sound waves, which are not as delicate as light waves, and the highest resolution is only about 10 centimeters.

The simulation continued. This time, ultrasound was used.

Ultrasound is more efficient, has a shorter wavelength, and the scanning results are more delicate, with a scanning accuracy of 3 centimeters.

The hearing gene continues to be turned on and strengthened, and it begins to strengthen the cells throughout the body, so that the skin has the ability to perceive sound.

Then a variety of sound waves are combined, and points, lines and surfaces are calculated at the same time, and the scanning accuracy finally reaches about 1 centimeter.

However, from the beginning to the end, the world that the wind of perception "sees" is black and white.

The simulation continues.

This time, Chu Fei appears underwater.

Can the wind of perception only be used in the air?

Not true.

The essence of the wind of perception is sound waves and vibrations, so it can be used underwater as well.

But the effect underwater is much worse.

The speed of sound in water is about 4.4 times that of sound in air, which means that the wavelength increases and the perception results become rougher.

But as the speed of sound in water increases, the efficiency of the wind of perception increases sharply.

The next simulation is perspective.

Scientists use infrasound waves to detect the internal structure of the earth, and ultrasonic flaw detection is also used in medicine or industry.

However, this also requires more powerful computing power.

In the simulation, Chu Fei's whole body hearing gene is turned on, and his skin and bones have the ability to perceive sound or vibration.

Using sound waves, Chu Fei "sees" the inside of rocks and trees.

But the perspective ability of sound waves is completely opposite to visual experience.

Because the harder the material, the better the sound permeability. Therefore, under the perception of sound waves, steel is "transparent", but air is not transparent.

After collecting data, input the sound speed parameters of different materials for rendering, and finally get the inverted result, you can restore a normal world.

But the world under the wind of perception is still black and white.

Until the next simulation: color vision, borrow the way of music to edit data.

This time, sounds of different frequencies, different perception methods, different data collection methods, different calculation methods, etc. began to be calculated in parallel.

A "colorful" world appeared.

But the "color" under the wind of perception is completely different from the color of vision.

The "color" here refers to the hardness and flexibility of the material.

According to a series of reference data such as the speed of sound of different materials, refraction and reflection of sound, sound absorption, interaction between sound of different frequencies and materials, the actual situation can be restored.

The "color" here refers to the color of sound, which can be understood as music.

The simulation gradually ended. Finally, Chu Fei closed his eyes and felt an alternative "vision":

The wind blew gently through the treetops, birds sang, springs flowed, and small furry animals with big tails as big as fists quickly climbed over the tree trunks. The fallen leaves gently fell into the spring water, causing clear waves, fish jumped out of the water, and long animals were winding underground...

Chu Fei stepped on the fallen leaves and wandered in this world of music.

This is... the sound of nature!
