Hearing Jiang Li's words, the first reaction of most of the people present was disbelief.

The main reason is that Jiang Li is too young, and many seniors haven't figured out how to do it.

There were also a small number of people left who wanted to see what tricks Jiang Li could make.

Seeing that Jiang Li had become the target of everyone, Liu Zixian hurriedly said: "Xiao Jiang, don't worry, sit down first." ”

But Jiang Li was not reckless.

It's just that in a paper at Zhejiang University in my last life, this process was indeed mentioned.

He also read and studied, and the ideas in it are indeed feasible.

"Housheng, you're not talking nonsense, are you?" Hu Jianxin was not angry, but asked.

Jiang Li replied very simply: "I can use the computer in the conference room to project the screen on the spot." ”

Courage is commendable.

I just don't know if it's really something, or it's grandstanding.

Hu Jianxin's face was slightly old, but his eyes were bright, and he stared at Jiang Li for a while: "Okay." ”

"But I'm going to say ugly things ahead, if you can't do it, you go to the toilet with your trainee teacher."

Liu Zixian: ???

The old man's tone of voice was very easy-going, and his words were like jokes, which made Jiang Li feel a lot closer.

Jiang Li stood next to Hu Jianxin, operating the computer and explaining at the same time.

"At present, computer-generated paper-cut style animation has only existed in theory, but after my research, I have initially discovered the way to use computers to make paper-cut animation."

Jiang Li already has the consciousness of copying the work, and now he doesn't blush at all.

"Using Visal C++ as a tool, we can make a simple cut-out style animation of a boat crossing a river by constructing functions."

Constructing functions?

Can cut-out style animations be made with functions?

This idea is strange.

It can really make the process a lot easier.

It can also be regarded as injecting new vitality into information technology for paper-cut animation.

Everyone couldn't help but get up to color at this time.

"For example, the river ripple can be regarded as a transverse water ripple, denoted as W(u), which can be expressed by the sine wave W(u)=(A+Δ)sin[(ω+Δ)u+Δ]."

Everyone nodded their heads, indicating that they could still understand this.

With Jiang Li's operation, a paper-cut style water ripple appeared on the big screen.

"Can you still animate like this?"

"Learned."

Jiang Li went on to explain:

"where u is the normalized transverse world coordinates, but in order to avoid the mechanical sense brought about by the consistency of the amplitude and period of the sine wave, it is necessary to add a small random disturbance △ to the amplitude A and angular frequency ω of the sine wave, so that different transverse water ripples are staggered between the peaks and troughs, which is used to simulate the effect of hand-cut paper......"

Liu Zixian's face was embarrassed.

He just took a nap, and he couldn't understand it.

At this time, he remembered that when he was in college, his teacher gave lectures.

The difficulty of "1+1=2" in the last second is still simple.

When I picked up a pen, I looked at the blackboard.

It is the difficulty of solving "1+1=2 to verify Goldbach's conjecture".

And he's been engaged in paper-cut animation and hand-drawn animation.,I haven't eaten the computer stuff very thoroughly.,I can understand every word.,Why can't I understand it when it's connected.。

Didn't Jiang Li say that paper-cut animation, he would only be a little bit?

Looking at Jiang Li, who was talking eloquently above, and recalling Jiang Li's sentence "It will only be a hundred million points", Liu Zixian fell into deep thought.

"Then use the function to build the wave pattern and model the boat......"

"A ship is a vectorized model generated through control points...... In order to exaggerate the intensity of the current, we rocked the ship in the animation......"

Jiang Li's operation process is smooth and pleasing to the eye.

As his last sentence falls, a cut-out-style animation of a boat rocking through the ripples of the river appears on the screen.

"I didn't understand ...... very well"

"He doesn't know this knowledge......"

Except for a few experienced old men who can use both computer animation software and paper-cut animation, few people present, including Liu Zixian, can understand Jiang Li's method very well.

However, Hu Jianxin's eyes flashed, and he hurriedly announced the dissolution of the meeting and left in a hurry.

Call.

Found a treasure.

The paper-cut animation department may not need to be disbanded.

After Hu Jianxin left, colleagues from the paper-cut animation department surrounded him.

"Jiang Li, your idea is also unique."

"I've got to go back and dig into it."

"There's a place I'd like to ask ......"

……

In the spacious office, the energetic old man wears reading glasses, sits in front of the computer, tapping and typing.

"According to the later generation, build the function first, and then ......"

Although Hu Jianxin is old, he has been learning how to use computer animation software to make animations since the rise of computers in China, which is one of the reasons why he can still serve as the director of the studio when he is over 80 years old.

He belongs to both the conservative side of traditional animation and the reformist side of emerging animation.

So he has always been very concerned about the reform of traditional animation and injecting vitality into it, but he has no way.

Jiang Li's words today made him pause.

"No, this place doesn't work......"

"What did that kid do? Why can't I do it? ”

Hu Jianxin stopped what he was doing, closed his eyes to the meeting, suddenly realized, and smiled: "He also hid a hand, and there was a step in the middle that he secretly did with a computer, but he didn't explain." ”

"Xiao Zhou, you go and help me call the intern brought by Liu Zixian, and I'll ask him a few questions."

A few minutes later, Jiang Li came to the office.

"Hu Lao is good." Jiang Li greeted him naturally.

"You little fox, you don't have a good heart." Hu Jianxin smiled and did not debunk it.

"Old Hu, I don't understand much." Jiang Li was still pretending to be confused.

"I deliberately left a loophole so that I can't do the next steps, do you want me to give you something?"

Jiang Li knew that he had been discovered, and said with a smile: "I know that I can't hide it from you." ”

"What do you want? Just don't go too far. ”

"Old Hu, I want to find you to learn to be a candy man."

Hu Jianxin was stunned for a moment.

This answer was something he hadn't expected.

Are there still young people who like this craft?

"My friend likes to eat small snacks, and I want to learn to make my own and give her as a gift."

Hu Jianxin nodded: "This is okay, but you have to explain the missing step first." ”

The missing steps are not complicated, but they are crucial.

Jiang Li also quickly explained clearly.

"Old Hu, I remember that you just said that you were going to disband the hand-drawn animation department."

As soon as he mentioned this, Hu Jianxin became worried.

He also explained this matter to Jiang Li in 1510.

The dilemma of hand-drawn animation and cut-out animation is not the same.

The dilemma of paper-cut animation is that it can't keep up with the times, and just through Jiang Li, there is a way to solve it.

But the dilemma of hand-drawn animation is that it can't produce good films.

If you can make a good film, so that you can see that the hand-drawn animation still has a future, it will be easy to do.

"Old Hu, there is actually another way."

"Oh?" Hu Jianxin was interested.

"Isn't our studio going to make an animation of the opening ceremony of the Huaguo International Animation Festival, I think we can make a hand-drawn animation and show it at this animation festival."

That being said.

But again,

Animation is not easy to do, and good animation is even harder to do.

What's more, it's such a laborious and laborious hand-drawn animation.
