Then there are parallel lines. Each line is parallel and does not cross, and the spacing is unequal (keep a spacing of 5mm), which is somewhat similar to the flat line when sketching tone adjustment, but the line should be long enough, which is about the short side length of A4 paper (2 1cm), until the whole A4 can be drawn with parallel lines. I personally use A3 paper when practicing parallel lines, which can lift my wrist to the end. When the horizontal direction is full, use the vertical direction and then tilt it at 45 degrees. You can draw hundreds of lines on a piece of paper. I believe that if you stick to 1 week, the straight line will be drawn straight. )
Curve, draw a curve through three points, ensure that all three points are on the curve, and require the curve to have tension and speed.
An ellipse is actually a circle with various angles, including a perfect circle. All kinds of fine arts majors, design majors and architecture majors should draw circles. If you draw a digital camera into a product, I will watch it. The concentric circles of a lens are more difficult to draw than the rims of a car. ...
The above are some basic education of ACCD, and there are some similar courses in Tsinghua Academy of Fine Arts. I don't know if there are such basic courses in other schools, but hand-drawn techniques are necessary.
When I was at school, I used to watch Master Feifei (now a designer of Mitsubishi Japan Design Center) do some exercises of this kind of lines before painting, which was extremely hard and serious. ...
-The second shortcut to practice fast expression skills.
Many students have realized that without hard work, there is no way out for employment. So I will briefly introduce the rapid performance of learning here, hoping to help everyone!
I have summarized the practice of fast acting for many years, which should be helpful to the students' practice.
First of all, you should give yourself a "May Plan" and reasonably arrange the study plan for each time period. It doesn't take long to perform quickly, just stick to it for an hour or two every day.
In the first month, the translucent sulfuric acid paper was pressed on the perspective line drawing and strict copying practice was carried out. (mainly practice the smoothness of lines, seek the vivid charm of lines, and summarize the perspective law)
In the second month, replace the sulfuric acid with A4 copy paper, and don't put it on the line draft data. Instead, put the picture aside and copy it. (mainly practice perspective method to clearly show the structural relationship of the line draft in the picture and the relationship between front and back occlusion)
In the third month, find some computer renderings and copy them with sulfuric acid paper (this mainly exercises the ability of transforming pictures into line drawings and also the generalization ability of pictures! )
In the fourth month, do sketch exercises on computer renderings or real-life pictures. At this stage, you mainly exercise comprehensive training from pictures to line drawings. At this time, you are not far from success! )
In the fifth month, do coloring exercises. Coloring is a relatively general and systematic process, and these specific steps can be seen in my other blog posts.
-No.3 the most effective way to draw a good sketch.
I believe you have seen many sketches drawn by foreign masters, all of which win with beautiful and smooth lines! In fact, the most important quality of sketching is the straightness of lines.
What most people don't draw well is actually that the lines are not smooth, there are too many repeated strokes, the lines are not straight, or the curvature is not smooth. Generally, the lines begin to thicken when drawing. It's unnatural. These are the main problems! There is also the angle of view is not allowed! ! This is a big taboo when sketching! ! However, it is natural to commit crimes again and again. The problem mentioned above is that the sketch is not good-looking. Look at foreigners'. Foreigners pay attention to the practical application of theory, and perspective is a key to drawing, so they pay great attention to perspective in practice. When perspective can be solved, they begin to practice focusing on lines.
Accurate perspective and smooth lines are the criteria to judge whether it is good or not! Another point is the degree of grasp of the sense of volume. I have to admit that foreigners are doing very well! ) The above is to give you a correct understanding of sketch. How can I draw well? Let me explain them one by one.
1 It's important to find some perspective books first and study hard!
The straight perspective error of drawing lines is equal to zero! ) to deeply understand the three principles and basic aspects of perspective! It doesn't matter if the line is not well drawn, but the perspective must be accurate! Remember! As long as you recognize it, you will know the perspective of the object like the back of your hand within a week.
You think it's almost enough, so start advanced training.
Don't look at objects and draw silently, of course, it's not simple geometry, such as drawing three views of cars, buildings and people's action expressions. Look at your ability!
If you have completed all the above training well, congratulations, you are a 60% master.
Why do you say that? Because you have the basic qualities of a designer, which is also one of the most important qualities. )
4 To draw lines accurately, practice drawing straight lines first.
The method of writing is sketching, and the lines should not be drawn too short, but should be completed at a faster speed! Look at the line you drew! If you can't, practice more until you draw straight! Generally, it doesn't take a long time, and at the same time, you can practice drawing objects with complex geometry (equal to practicing perspective and feeling)
Drawing curves is a great difficulty, but it is no problem to practice carefully.
Practice drawing a circle first, using 4-point positioning method and 8-point positioning method. A circle is made up of (arc = curve). Draw a circle, draw a half arc = draw a curve! If the circle is well drawn, then the curve will naturally be well drawn. If you draw more, you will feel it, so it is not a problem to draw any curves!
Sketch is a combination of straight line, curve and perspective.
If you want to draw quickly, accurately and well, then the above steps are necessary! ! ! That's how foreigners draw well. So let's not be afraid!
You have done more than 7, then you have squeezed into the ranks of experts 90%.
If you have a good grasp of the texture of the object, what about 97% and 3%? Because there is no 100% expert (it is impossible to be really perfect), the four-point positioning method is to divide four bisector points (0 degrees, 90 degrees, 180 degrees, 270 degrees, 360=0 degrees) on a circle and then cut out along the four points with a straight line. After the connection, it is not round, and it is cut along the inner line at the midpoint of the tangent. (The principle is the same as 3D polygon forming. ) [The main thing is to practice your hand, just practice more.
Eight is just eight bisectors (more accurately, it is suggested to start at 8 o'clock, and 4 o'clock is better). The most basic drawing method is to hold the pen horizontally by hand and write backwards.
Advantages are high balance and high speed (the method used in sketching and paving). The disadvantage is that it is easy to fabricate and the description is not deep. The straightness of drawing lines is directly related to the balance reading. This is different from boxing, because in reality, no one will use the slow method instead of the fast method! Your idea is the same as that I started practicing. There are only two ways to hold a pen in painting (horizontal and straight), and other ways are based on this. Just like painting surrealism enters the stage of characterization (thumb and forefinger hold the first 2/ 1 of the pen body and press the paper with fingers), the biggest advantage of this painting method is that it can draw very subtle parts. The disadvantage is that you can't draw long lines in a large area, so it is used to describe parts! Each method has its advantages and disadvantages, but in order to draw a sketch instead of realism, just use what I said, and don't let everyone take a detour! Some foreigners draw with their left hands, which is related to other languages. English writing is easy to write by hand, but Chinese writing with left hand is not easy, but I believe no one writes with left hand! Generally speaking, this is the case, of course, sometimes we still have to learn to use it, and we must be able to draw inferences from others.
-copy method no.4.
After a single practice of lines, you need to copy the complete "line drawing" flower-and-bird works after you have a certain understanding of the running law of lines. "Sketch" is a kind of painting form that uses pure lines to represent objects. It is said that it originated from Wu Daozi, a painter in Tang Dynasty. However, "line drawing" is different from "line drawing" before coloring, because it does not use any appendages (such as color) to express objects, so "line drawing" pays special attention to the expressive force and appeal of lines themselves, and has developed to the present.
There are two main ways of copying, one is "copying" and the other is "facing".
(1) "Copy"
"Copying" is a method of covering the replica with a thin layer of translucent cooked rice paper and then drawing it according to the shape of the original. This method is like "painting red" in calligraphy practice. "Copying" is mainly about practicing lines, which is also helpful to modeling, but this method is only suitable for beginners. After mastering certain line skills and modeling ability, you can't continue this practice.
"Face"
"Face-to-face instruction" is a method of putting the copy aside, gently drawing the image of the copied object on the drawing with a pencil, then copying it according to the pencil draft, and then comparing it with the copy. Compared with "copying", this method has the following advantages: a, it can directly tick the lines on the drawings without being influenced by the image of the copied products, which is of great help to the understanding and free play of the lines; B, "duality" can help to understand the growth structure of animals and plants and the weaving of lines. Therefore, after having a certain business and modeling ability, we advocate "face-to-face" practice.
When copying, you should practice selectively according to the basis of painting and the mastery of lines. Copying should follow the principle of from easy to difficult and from short to long, and practice step by step with purpose.
A. Short-term copying practice
There are many twists and turns in the short line, so we should pay attention to using the method of "frustration" at any time and adjust the trajectory of the pen tip in time to avoid the phenomenon of "sideways". When you hook a line, you should "moisten your wrist", that is, use the movement of your wrist to outline lines, and avoid drawing lines with your fingers, so that you can always maintain the "central moistening pen".
B. Long-line copying practice
Don't be nervous when drawing long lines, especially pay attention to the peace of breathing, so that the lines can be smooth. Pause when you start writing, move your arm when you write, and keep the pen in the middle, so that the lines are like a cone scraping sand and penetrating the back of the paper.
C. Decomposition and copying exercises
The decomposition diagram is a decomposition description of different growth periods, different growth structures, different parts and different perspective angles of flowers, so as to understand the growth structure and perspective law of objects more deeply and thoroughly. This method is widely used in flower sketch, but it should also be practiced purposefully in line practice to deepen the understanding of copying objects.
D. Composition copying practice
Composition copying practice is to copy a picture with complete composition. Through copying practice, we can understand and master certain composition rules and skills.
[For the above methods, you should practice selectively, and you can practice all the methods that can be absorbed. If it cannot be absorbed, the practice difference is equal to zero; Of course, if we can explore our potential qualities, it would be better to absorb more methods. ]
