Linear sketch? Three questions?

1, what is a linear sketch?

As the name implies, linear sketch refers to the sketch language form with more lines, less light and shade, more body structure and less light and shadow tones.

2. Is structure sketch a linear sketch in Chinese painting and design sketch?

The answer is yes. Both line drawing and structure sketch are generalized linear sketches, and both are sketch forms with lines as the main expression language.

3. How to define linear sketch in plastic basic education stage?

This problem involves my own teaching practice, that is, the basic modeling teaching in the attached middle school. Modeling training at this stage is different from traditional Chinese painting and structure sketch's design. There is no clear professional orientation, it is pure modeling training. I'm going to talk about this narrow linear sketch, not a broad linear sketch, including Chinese painting and structure sketch.

Reflections on linear sketch in the teaching of basic modeling

What do you think of the existing sketch teaching after summarizing my teaching practice in recent years? Cut surface? I have some personal views on the concept, the treatment of virtual reality and the treatment of black, white and gray.

? Cut surface? Concept VS? Bang Qi. concept

The content arrangement of sketch course for middle school students attached to China Academy of Fine Arts is: from plaster geometry to still life, and then to? Cut surface? Plaster, then plaster, then transition to real head and bust. In fact, this curriculum arrangement has already reflected the teaching thought of Che Shakov, and gradually advanced from geometric section to physical object. In addition to the course arrangement, teachers often ask students to use it in the specific explanation of the class. Physical quality? When it comes to the process of painting, it is to shape first, find out the outline of the body, then start to divide it into three major areas, cut it step by step, and finally complete it. The advantage of this teaching method is that it can help students to quickly establish a sense of space and volume, but it is also easy for students to fall into? Cut surface? In the trap, everything is multifaceted, over-analyzed, under-synthesized, and finally unable to go deep, and the picture always lacks the original feeling of flesh and blood.

? Bang Qi. Is the concept from part to whole? Grow up? Process, and then what? Cut surface? The concept is from the whole to the part? Subdivision? This process. ? Bang Qi. Require respect for the object itself? Knitting? Is the painting process an explanatory object? Knitting? Process; ? Cut surface? Ask the painter to take the initiative to use the concept of volume to carry out objects? Deal with it? , this kind? Deal with it? Maybe someone respects it? Knitting? Yes, you can also disrespect the object? Knitting? . ? Bang Qi. This concept requires special attention to the tissue relationship between masses (mutual infiltration, occlusion, etc.). ), that is, we should pay attention to the boundaries of blocks (how to start, how to end, how to transition from one block to another), so that lines are widely used in classical sketch as a language that can effectively describe the boundaries of shapes (because lines are formed by the turning and disappearance of surfaces); ? Cut surface? The concept requires approaching the object step by step from big to small, so the relationship between faces is only relative, because the relationship between faces will change in the next subdivision.

Virtual-real relationship

In the past sketch teaching, students were often asked to deal with the relationship between reality and reality of objects. The general principles are: the front (near) in space should be realistic, and the back (far) in space should be imaginary; ? Does it matter? Some parts (such as eyes) should be painted realistically. Secondary? Part of the painting should be empty. I found in the process of studying the sketch of the European Renaissance that the sketch of that period was `? Treatment of deficiency and excess? This is not an iron law. Many sketches have a sense of incompleteness. They often finish drawing the main part and leave the rest unfinished, which makes people feel that there is a kind of? Virtual or real? This feeling. But if we look at some murals at that time, take Michelangelo's "The Witch of Libya" as an example, the witches in the murals are complete from beginning to end, and the characters are clearly explained from head to toe, not like witches in sketch practice? Virtual or real? The part of the right hand and hair that stretched out far away was not depicted. This reminds us that the treatment of truth and falsehood is not the most concerned thing for Renaissance painters, but it is dispensable.

I advocate that the picture teaching should not be overemphasized in the basic teaching stage of modeling? Treatment of deficiency and excess? On the contrary, students' attention should be focused on observing and refining the texture of objects as much as possible.

Black-white-gray relation

The relationship between black, white and gray is somewhat similar to the relationship between reality and reality. From the picture, the treatment of black and white ash is emphasized in China's freehand brushwork (five-color ink) and modern art (Picasso's guernica). The treatment of black and white ash has become a kind of? Performance? Language.

During the Renaissance, the treatment of black, white and gray was not promoted to? Expression language? Status, it mainly follows the black, white and gray relationship of the object itself, and sometimes it often ignores the black, white and gray relationship of the object and focuses on the form. For example, many portraits and sketches of Diu Lei put hair, clothes and face in the same lightness and tone, and he paid attention to the characteristics of the form itself.

At present, there is a tendency to overemphasize the treatment of black, white and gray pictures in basic modeling teaching, and the shape itself is often ignored in this emphasis. Knitting? The importance of relationships.

From the sketches of several Renaissance masters and their other works, we can see an artistic concept that takes objects as the starting point and fulcrum and finally returns to them. What is the expression of this artistic concept? Linear sketch? . Regarding the linear sketch in that period, we can easily get the following understanding: 1) Is the linear sketch used for the research object? Knitting? And its characteristics. 2) of the object? Knitting? And its characteristics can be intuitively grasped, and it can be directly expressed by lines (supplemented by a little tone) without going through it? Faceted? This step by step process. 3) Need to be able to distinguish intuitively? Essential? Content and? Non-essential content, keep the former and abandon the latter when describing. 4) ? Essential? Does the content include physical objects? Bang Qi. And then what? Bang Qi. With what? Bang Qi. The relationship between. 5) The end and beginning of the surface form lines, so? Bang Qi. The relationship between them can be well expressed by lines. 6) So there are no independent lines, and each line has its own degree of belonging, either to the form or to the background. 7) Lines can be divided into light receiving and backlight. The light receiving surface is shallow, and the backlight line is deep. 8) Draw the boundary of the block and the relationship between the blocks through lines, combine the blocks into new shapes (such as arms), and then combine the shapes into a complete figure. The shaping process of linear sketch is promoted from local to whole. 9) Not based on objects? Deal with it? (such as virtual and real picture processing and black and white grayscale processing) should be as little as possible. 10) What is the ultimate goal? Back to the object itself? , put aside? Faceted? , apart from the picture processing, is to make the object itself? Talk? . 1 1) ? Back to the object itself? In the future, with whom? Knitting? Will be revealed, it will give the picture a real sense of power and lead to the source of artistic creation.
