Chapter 198: Sketch with math

,
After eating, Lu Li picked up his schoolbag and returned to the room.
The calligraphy and painting utensils he purchased hadn't arrived yet, so Lu Li used other methods to practice.
On the way home, Lu Li bought a set of calligraphy and writing cloth.
Open the water writing cloth and spread it out on the desk. Lu Li picked up a brush, soaked it in the glass jar with water, and started writing.
In accordance with the basic brushwork taught in the Introduction to Calligraphy, from the sitting posture, the posture of holding the pen, to the method of raising and lowering the nib, Lu Li is meticulous.
Calligraphy begins with regular script.
Lu Li had memorized Yan Zhenqing's regular script copybook in his mind, and the glyph structure of each character was clear.
Imitating Yan Zhenqing's regular script, stroke by stroke, square and steady, meticulously written.
In a moment, the water writing cloth was covered with square characters.
Lu Li nodded with a smile while looking at these handwritings.
Never forget this is a magical skill, no matter what the plot, it can be used, and it has a great effect.
I remembered the copybook of Yan Zhenqing's regular script in my mind, and the structure of each word was clear. It is very convenient to copy and imitate.
Coupled with "calmness", Lu Li's temperament is calm, not impatient or impatient; "Ingenuity" makes Lu Li's hands dexterous and easy to master.
Even though I rarely wrote calligraphy with brush in the past, the calligraphy I write now is still pretty, not crooked and unsightly.
"Okay!"
Lu Li nodded slightly, turned around and took out the hair dryer from the bathroom, and blew on the writing cloth for a while.
Water writing cloth is easy to dry, but it dries faster when blown by a hair dryer.
Putting down the hair dryer, Lu Li picked up the brush and started writing again.
Under the influence of "God rewards hard work", every time Lu Li practices, he gains and improves.
Because the whole family had to get up early, Lu Li did not write that it was late. At eleven o'clock in the evening, Lu Li packed up his things and went to bed.
Go to school the next day.
When Lu Li came to the classroom, the fat Yuwen at the same table yawned, his eyes were bloodshot, and he looked like a "girly fairy with a stick and a silk hole".
"Old Lu, my new book has been reviewed!"
Seeing Lu Li's arrival, Yuwen Fatty said with excitement: "I stayed up all night last night and wrote three chapters with more than 10,000 words. Now it has been reviewed, and mine has been published on the website."
"More than 10,000 words? Have you signed a contract?"
Lu Li asked casually.
"Signing...signing? What is signing?"
Yuwen Fatty was puzzled.
"Signing is..."
Lu Li thought for a while and said to Fat Yuwen: "Your work is signed on the website, and the sale is shared. If you don't sign a contract, you can't put it on the shelves, and you have no money. That's probably what it meant.
"Then... how can I sign a contract?"
Fat Yuwen is very concerned about this.
"The editor thinks your work has commercial value, that is, if the editor thinks your book can sell for money, it will sign a contract with you."
Lu Li smiled and patted the fat Yuwen on the shoulder, "Come on! The first step is to meet the signing criteria."
More than 10,000 words have not come to sign the station short, it should be rushed to the street to even sign.
But... maybe. It is said that there is a sacred book, only 600,000 characters were signed, but it was very popular, and one book was a god.
"Does it meet the signing criteria?"
Fat Yuwen nodded, "I understand. This is the practice upgrade in Li. I am a novice now. I must first upgrade to signing, and then I will upgrade the author's level, all the way to the platinum throne."
"Good savvy!"
Lu Li nodded appreciatively, "Heavy rain, you have a platinum posture. Work hard! I look forward to your book reaching the top and proving Taoism and God."
"necessary!"
Yuwen Fatty laughed and his fighting spirit was high.
"Why are you laughing? I'm in my third year of high school, and I don't know how to study seriously?"
With a roar of anger, Old Xu blew away Yuwen Fatty's spirited spirit and fighting spirit.
With his neck shrunk, Yuwen Fatty quickly immersed himself in reading.
Old Xu's "spur" Lu Li was still fresh in his memory, he didn't dare to stab him, and honestly picked up the workbook.
It's just... Lu Li took a pencil in his hand and drew a sketch on the workbook.
When drawing a sketch, Lu Li once again lamented the powerful auxiliary role of "not forgetting".
Once I saw it, I remembered the picture in my mind.
Lu Li paints, he only needs to paint the picture in his mind.
Sketching requires a certain spatial imagination and spatial positioning ability. In essence, spatial imagination and spatial positioning are all mathematical problems.
Mathematics is exactly Lu Li's strength.
Just thinking about it, Lu Li immediately constructed a spatial coordinate system in his mind, and then determined the coordinate positioning of the picture by means of view and projection.
Pen on the paper, with the center line as the reference, accurate coordinate positioning of the entire composition, accurate proportional size calculation, and perfect light projection angle of view.
The tip of the pen flicked on the workbook, and his calm mind made Lu Li very calm, and his ingenuity made Lu Li's strokes very accurate.
At the beginning, what appeared on the paper was a coordinate system, then one coordinate point, and then one projection line.
The paper at this moment is completely a geometric figure, no one thinks it is painting.
Even Lao Xu, who was passing by, nodded slightly when he saw the coordinate axis and projection line drawn by Lu Li on the workbook.
The three-dimensional coordinate system has precise proportions and rigorous composition, that is, the coordinates of the points appear to be irregular. This is... what curve is being calculated?
Old Xu Chaolu glanced at Lu Li, a glimmer of appreciation flashed in his eyes. Not bad! From this coordinate system, it can be seen that Lu Li's mathematical foundation is not bad, and he has made great progress.
A smile appeared at the corner of his mouth, and Old Xu nodded slightly. It's already a third year of high school. With this progress, as long as you keep going, taking a bachelor's degree is not a problem.
With his hands on his back, Old Xu patrolled the classroom.
After turning a circle, Old Xu was also very relieved to see that the classmates were studying hard. After all, it is a key class, the learning atmosphere is still relatively strong, and the style of study is still relatively good.
Turning around to go out, when he walked to the door, Old Xu saw Lu Li still drawing on the paper.
Ok? In a coordinate composition, a curve can be obtained by taking a few key coordinate points. Why hasn't it been calculated for so long?
As a teacher, but also a math teacher, preaching, teaching and solving puzzles is my job.
Old Xu stopped, turned around and walked towards Lu Li.
Walked to Lu Li's side and looked down...I'll go!
Old Xu's eyes are about to bulge out!
Where is the coordinate composition and where is the curve calculation?
On Lu Li's homework book, he suddenly drew Old Xu standing at the door of the classroom, staring at the classmates in the classroom.
The precise size ratios, perfect spatial coordinates, and appropriate light projections portray Lao Xu's image to life, and even the expressions in his eyes reveal a sense of gaze.
What shocked Old Xu even more was that in this picture, even the wrinkles on his face were very accurate, and it gave Old Xu the feeling of looking in a mirror.
The reason why Lu Li was still drawing screaming and screaming was because... he was taking points for each wrinkle, calculating the coordinate points, and drawing the wrinkle curve.
At this moment, Lao Xu didn't know what it was on his face and what it was like in his heart.
You even calculated every coordinate point. Have this ability, just to draw a picture? And... You painted Lao Tzu so ugly?
"Good drawing!"
Old Xu knocked on the table, staring at Lu Li with no expression.
"what?"
Lu Li was immersed in the painting, and he came back to his senses after hearing this.
Looking up to see Old Xu, Lu Li looked at the painting drawn on the paper again, a flash of embarrassment flashed across his face.
"Bring your painting and follow me!"
Old Xu waved his hand, turned and walked out of the classroom.
"Lao Lu, you...can still paint?"
The fat Yuwen shuddered when he saw the old Xu drawn in Lu Li's workbook, "You...what are you doing badly? Why do you paint Lao Xu? Are you drawing evil spirits?"
"A memorial."
Lu Li picked up the workbook, got up and walked out of the classroom, and came to Old Xu's office again.
Old Xu sat at the desk with a cigarette in his fingertips, took a slow sip, raised his eyes to Lu Li, "Show me the painting."
"Ok!"
Lu Li quickly handed over the workbook.
Old Xu reached out and took the workbook and opened it to see the painting. Looking at the calculations on the next page, Old Xu's eyes became a little helpless.
"You calculate so many coordinates and so many curves, just to draw a picture?"
Old Xu didn't know what to say.
You said Lu Li is not doing his job right? When he was drawing, he clearly did countless math problems, solved countless coordinate points and countless curves.
You say he is doing business right? He did so much just to paint a picture.
"Sketch is true."
Lu Li smiled, "Mathematics is the most authentic language in the world. Any sketch is essentially composed of points and lines. Points and lines are all mathematical problems."
"Draw with mathematics..."
Old Xu touched the deep head of the hairline, with a strange look on his face, "From this picture, you can see that your math level has improved a lot. As long as you keep going, you can take a key undergraduate exam during the college entrance examination. There should be no problem. What are you...studying painting for?"
"Art students can also take key undergraduate exams."
Lu Chengtou was also a little helpless. I came to be a "master of craftsman", learning a master... it was not my mission route.
"Do you want to take the path of art students?"
Old Xu almost choked on a cigarette.
Reaching out and pressing the cigarette out in the ashtray, Old Xu raised his eyes to look at Lu Li, "Specialty in art? This road is not easy to walk! And... with your grades, is it not good to try hard to get a hard copy? Why? Are you going to narrow the road?"
In high school campuses, there is a general idea. That is, the cultural examination is the right way. Students specializing in sports, music, and art are all "siders".
I can't help it! Who calls the task requirement a "master craftsman"?
Lu Shili sighed inwardly, passing the admission to the "Central Academy of Fine Arts" through art expertise is only the first step for "Master of Crafts". There are still many things to do in the future.
"Teacher, I am interested in this."
Lu Li could only explain it this way, "Because I am interested, I have improved my mathematics in order to paint. This...should be a good thing?"
Interest is the best teacher, and interest is of course a good thing.
Old Xu secretly sighed, "You are still young, this kind of life path choice should be discussed with your parents. In any case, you can now improve your math level, the teacher is very happy."
"Thank you, teacher."
Lu Li also knew that Old Xu was out of concern for and responsibility for the students, so he talked to him.
"alright!"
Old Xu Chaolu nodded, "Go back and discuss with your parents. If you must take the art route, you can't ignore the culture class. After all, culture is the foundation."
"Okay! Thank you teacher."
Lu Li thanked Old Xu and stood up to say goodbye, "Teacher, I will go back first."
"Hmm! Go down!"
Old Xu waved his hand towards Lu Li.
Lu Li turned around and walked out of Old Xu's office and returned to the classroom.
"Lao Lu, I thought about it just now, and suddenly I felt...you are brave."
When Lu Li had just returned to his seat, the fat guy Yuwen at the table next to him came up thiefly.
"Brave? Why do you say this?"
Lu Li was taken aback, not knowing what Fatty Yuwen was talking about.
"You painted a portrait of Lao Xu! Your painting looks like a portrait!"
Fat Yuwen winked at Lu Li.
"Remains...remains?"
Lu Li flipped through the homework book and found that in the frame of the homework book, Old Xu's lifelike face actually smelled like a "retreat".
"Nonsense."
Lu Li yelled, and quickly tore off this "portrait", so that it would not become "painting whoever died" under Fat Yuwen's brain, and making a "my tablemate is weird" or something like that. The brain hole comes.
There are basically no new classes in the third year class, all of which are review.
Do test papers, do all kinds of test papers, brush the questions, brush the questions desperately. Of course, if you have given up and do not want to do these test papers, the teacher will not say anything.
At this stage of the third year of high school, only those who want to enter university can feel the sense of urgency like burning eyebrows. Those who don't want to go to college will have a very easy life.
Lu Li didn’t make a difference either, he still followed everyone to do the questions step by step~EbookFREE.me~ Since he learned the plot, Lu Li has spent several plots, and he doesn’t have the habit of trying to finish when he sees the problem. .
Based on Lu Li's academic performance, you don't need to think about doing these topics, just write it by hand. After a little attention, Lu Li didn't care if he didn't get full marks on all of them.
There are art teachers in high school, and there is also a circle of art students.
Lu Li was about to join the art student circle in the next step, following the art teacher.
Art teachers know best how art students should take the exam, what they need to prepare, and what they need to pay attention to.
Art is not behind closed doors. Lu Li also needs guidance and communication.
One month!
Within one month, complete basic training in calligraphy, Chinese painting, sketching, and oil painting, and pass the test of the art teacher.
Then you can join the ranks of art specialty students.
