After Han Feng revealed this, Zhu Jun had no shame to stay there. He left with a blushing face, cursing the writer of the software while walking. At the same time, he made a secret decision in his heart that he would no longer study hard like before. He would also need to dabble in and study more techniques outside of books to avoid being as embarrassing as he is today.

"Hehe, I'm still good. You don't need to do it and you know that this software is fake." Li Wang showed a glamor on his face, and he was intoxicated and continued, "Madman, it's true that your computer technology is not as expected. No wonder Guozi has such a powerful technology, and he said he is not sure to compare with you. You are indeed a pervert, everything is so powerful! Around you, geniuses like me have become mentally retarded."

Han Feng stayed in the dormitory for a while, and Chu Shuai also came back, humming a relaxed tune, with a sweet look on his face.

Before he could walk into the door, Li Wang, who heard the sound, shouted: "The flower cynic is back."

Chu Shuai smiled and walked in: "I'm just a silly girl, what's wrong? Someone can't even be crazy about a silly girl, haha!"

After coming in, he discovered Han Feng and said in surprise: "When will the madman come back?"

Han Feng said: "It's not long before, it's fine today. Come and have a look."

Chu Shuai was a little happy: "You are back just in time, come and see the results of my hard work over the past period."

"What achievements?" Li Wang was very surprised.

"Preparation for the hacker competition!" Chu Shuai said while taking out his notebook, "Last week the organizer of the hacker competition officially announced the content of the competition. The inside information of the crazy man is indeed accurate. The original content of this competition was mainly encryption and decryption, but later several projects were added, including network intrusion and anti-invasion, as well as compression and decompression... This time the organizer also joined forces with a famous demo team in Sweden, the computer crossroad, to hold the demo competition that will be held next summer in advance. I heard that the two competitions will be merged into one in the future and merged into a large event."

Li Wang was confused and couldn't understand what Chu Shuai was talking about at all.

"Why are you talking about demo again? Is this hacker competition still engaged in CG animation?" Li Wang asked. He is familiar with game animation, and the first thing he thinks of is this.

Chu Shuaiyao said: "The demo I am talking about here is not the so-called demo versions of the so-called game released by game companies. In the field of hacking, demo represents another meaning."

"What does that mean?"

"You'll know if you look at this."

At this time, Chu Shuai's system had been started. He entered a folder on the D disk, pointed to an exe file called "Comet Crashed the Earth" with his mouse and said: "Did you see this executable file? This is the winning work of the Global Demo Competition that year."

"A comet hits the earth?"

Chu Shuai reminded: "Pay attention to the size of this file."

"63.4k?" Li Wang didn't quite understand what Chu Shuai meant.

Chu Shuai didn't say anything, and double-clicked to open the file.

Suddenly, the monitor suddenly turned black, which scared Li Wang. Just as he was about to ask if the computer was black, the screen began to appear in the monitor. First, there was a progress bar, and then it turned black again.

Then, a ball of light suddenly appeared in the dark display. As the lens slowly opened, it turned out to be an asteroid in the dark universe that was moving rapidly with light.

After a while, the asteroid came to a universe, and a blue planet appeared deep in the background. She was very familiar with the blue planet Li Wang, and it was clearly the earth.

Immediately afterwards, the camera switched to the earth, showing a lush and vibrant natural world, blue sky, white clouds, green grass, rivers...

Next is the bustling metropolis, where people in the city are in a hurry and live a very fast-paced life.

Seeing this, Li Wang was already very surprised because he suddenly realized that this thing seemed to have been running for a long time, at least for more than a minute.

The picture is 3d and quite realistic. Many of the game CG animations that Li Wang has watched can only achieve this effect, and this animation also has background music.

Li Wang was secretly surprised. He understood a little about what Chu Shuai meant by demo.

The animation continues.

After the picture on Earth, the picture begins to switch to that asteroid again.

Li Wang also guessed the following scene. The asteroid eventually hit the earth, causing devastating disaster to the earth.

The picture is very dazzling and the 3D effect is also very good. Li Wang almost thought that it was a trailer made by a film company for a 3D animation.

After the demo was over, Li Wang asked in shock: "Is this the effect of running the exe file less than 64k just now?!"

Chu Shuai nodded: "This is the demo in the hacker industry. Unlike those commercial demo animations, these demo works are all the results of program optimization, fully leveraging the ultimate potential of computer hardware, reflecting the advanced programming skills of the demo producers everywhere, achieving amazing results. You must know that the 3D animation for so long takes up less than 64k!"

Li Wang really couldn't understand the working principle: "Oh my God, what did this happen?"

Chu Shuai looked at Han Feng and said, "I don't know much either. I heard that it takes a team to make such a demo. However, the madman may know."

Of course, Han Feng knew that he had played this himself back then, but he had never seen the work of Comet Crashing the Earth, so it should have appeared later.

Li Wang then asked Han Feng: "Madman, do you know? Tell me, this thing is so amazing! Such a small thing actually played for almost ten minutes!"

Han Feng felt that there was nothing to hide. Although this thing was magical in the eyes of others, the principle was not complicated.

"The core of the demo is actually the compression and decompression algorithm. When you see the progress bar at the beginning of the picture, it is actually a decompression process. These programs are self-decompression. To achieve such an effect, these programs usually require writing in assembly language, because only assembly language can achieve such an optimized effect and give full play to the power of the hardware. In addition, demos often have to enter a special drawing mode, which is called the x mode. The very dazzling 3D effects I just saw are actually aimed at graphics cards.

Only in real-time programming can you save a lot of volume. Also, you have noticed whether the pictures in the demo have been taken seriously. If you observe carefully, you will find that many things inside are actually repetitive, composed of the same geometric figures. Repetitive things are often best compressed, because as long as you draw a piece of space to save the figure, other repetitive ones, just call the figure again, and the same is true for the music, over and over again, there are always a few tones..." Han Feng said it very simply and very much, even Li Wang, a computer novices, understood it.

"Guozi is right. To make a demo, it does require a team. Just like a game team, the demo team usually has a leader, who is responsible for overall planning. Programmers are definitely necessary. He is responsible for designing the entire demo program and considering what algorithm to use to compress and decompress it. In addition, there are special composition and artists responsible for music and graphics respectively. Of course, if you are strong enough, just be alone and get all these done by yourself." Han Feng often played all the roles in it alone back then. Of course, he also worked with others. Those people are the best in various fields. Doing these things is entirely for fun and showing his own technical level.

Although Chu Shuai guessed that Han Feng must have heard of this, he did not expect that Han Feng knew this so clearly and said it very well.

He was a little excited: "Madman, have you done such a demo with your own hands?"

Han Feng shook his head: "No, I just understand the principle."

Chu Shuai continued to ask: "How did you know? I want to see if there is any specific text information."

"Uh... I watched a foreign forum last time. I forgot which forum I looked online and found it. These things are not secrets." Han Feng said nothing wrong. These technologies are not secrets, but the core technologies are just circulating in small circles. Without real strength, you cannot get in touch with these things because others don't bother to communicate with you at all.

Chu Shuai was a little disappointed. Although his English was good, it was not easy to find these things.

At this time, Li Wang suddenly said, "Guozi, didn't you say you wanted to show us your results? What achievements have been achieved after you have been busy for so long? Is what you made also a demo?"

After he reminded him, Chu Shuai's spirit was rekindled: "I have been studying encryption and decryption algorithms for this period, not this."
