What are the basic features of design sketching, and what are the key points of sketching?

1. Composition. The overall effect of the picture is the most important, and the composition directly affects the final overall effect. In the process of painting, the composition should be full and complete, the sense of rhythm is strong, and the relationship between virtual and real is appropriate.

The shape has size, square and circle, the line has straight, sparse, long, and dark tones, and the light and dark tones have black, white, gray and so on. These are all factors that make up the rhythm of the picture, and they should be carefully considered before composing.

2. Key points of structure.

Drawing character sketches also requires understanding and mastering basic knowledge of human anatomy. In the training, learn more about the structure and morphology of bones and muscles, and the influence of these structures on the person in the garment. When sketching landscapes and animals, it is also necessary to carefully observe the morphology of plants and the structural characteristics of animals.

3. Dynamic proportion.

Dynamic proportions are at the heart of sketch performance. The first biggest problem in sketching is to master the dynamic proportional relationship. The spatial position and direction of the three major blocks of the figure basically determine the dynamics of the character, and the sketch requires that the physical characteristics and dynamic posture of the object be quickly expressed with affirmative lines in a relatively short period of time.

Generally speaking, starting from the large proportional relationship of the person, grasp the large position relationship of the five points (head, hands, and feet), then the dynamic proportion of the person can basically be established.

4. Shaping of heads, hands and feet.

The basic requirements of a good sketch are: proper proportions, dynamic stretching, smooth lines, thick and thin. Another point is that as an important component of sketching, the head, hands, and feet must have a sense of shaping when expressing, the head is often the visual center, the hands are the dynamic core of the character, and the feet play an important role in supporting the human body, so they cannot be taken lightly.

5. The expressiveness of lines and surfaces.

The characters are represented through the length, thickness, twists and turns of the lines, and interspersed. The focus of the sketch is on the lines that represent the structure of the human body, and the other lines are organized around the main line. The ingenious combination of the characteristics of the lines and the morphological structure is an important condition for the vividness and accuracy of the sketch.

Appropriately supplemented by light and dark tones, and the use of lines and surfaces to express the object, is conducive to increasing the sense of hierarchy and space of the picture, and improving the appeal of the picture.

1. The overall effect of the composition picture is the most important, and the composition directly affects the final overall effect.

2. Key points of structure: Sketching of characters should also understand and master the basic knowledge of human anatomy.

3. Dynamic proportion: Dynamic proportion is the core of sketch performance.

4. Shaping of the head, hands and feet: The basic requirements of a good sketch are: proper proportion, dynamic stretching, smooth lines, thick and thin.

It is necessary to deal with the "line" of each edge on the contour, structure and part to meet the requirements of "binocular parallax" of human vision.

5. The expressiveness of lines and surfaces: The characters are expressed through the length, thickness, twists and turns and interspersing of the lines. It is necessary to make the degree of depiction of the objects before and after the picture different, so as to conform to the visual experience of people.

6. First of all, it is necessary to determine and strengthen the chiaroscuro contrast between the objects before and after the picture, that is, light against dark or dark against light, which can be expressed by distinguishing the lines and adding light and dark tones, so as to meet the requirements of "simultaneous contrast" of human vision. No matter how simple or complex, ordinary or unique the object depicted, we must carefully consider and deal with the large effect of the picture before expression, and do not stick to one-sided partial portrayal.

7. The shape of the object in the picture should be deformed by perspective, so as to conform to the basic perspective law of the near and far of people.

8. Slow writing and silent writing: Slow writing is the key to drawing a good sketch.

9. Character sketching focuses on the description and capture of task dynamics (body posture); Architectural and landscape sketches focus on the understanding and expression of the objective environment and the objective scene.

Sketching] is to test the author's ability to observe objective things, understand, summarize and refine, and quickly realize objective things on drawing paper in a short period of time.

The sketch of the character must grasp the following factors:

1. Proportional factor.

Even if the work has vivid and accurate dynamics, but the proportion of the characters is not in place, it is also not a successful character sketch. Because the vivid and accurate dynamic sketch of the characters in the real sense must be based on accurate and reasonable proportional relationships. It is impossible to express the dynamic in isolation from the proportion, and it is impossible to avoid the dynamic to accurately reflect the proportion.

Proportions and dynamics are the most basic requirements in the scoring of the exam, which should not only accurately represent the dynamic characteristics of the characters, but also have reasonable proportions. It is very important to master the basic proportions to complete a good sketch of a character, such as the common dynamics of the object standing, sitting, squatting, etc., as well as the specific proportional relationship of the limbs, especially paying attention to the perspective changes in the real space. In this way, the proportional relationship can be accurately reflected visually, and finally the dynamic relationship of the characters can be truly reflected.

2. Dynamic factors.

A good character sketch is first of all able to accurately and vividly grasp the dynamic characteristics of the characters, because it is based on the dynamic relationship of the characters as the main performance content, and sometimes people also call the character sketch a dynamic sketch. Therefore, in order to achieve good results in the exam, it is necessary to carefully observe the object and carefully analyze the dynamics of the object, which is the key to success.

Dynamic, proportional, line, basic, if you want to draw better, you can draw more parts, not to mention hands, head, feet, etc., of course, the most important thing in a sketch is whether his dynamics are vivid. Sketching still needs to draw more, practice more, and achieve qualitative change from quantitative change.

Use concise lines to concisely draw dynamic or static images of people and objects in a short period of time.

A style of writing that is short, concise and vivid, and briefly describes the situation of meaningful things or people in life. It also refers to the expressive technique of describing characters or life scenes with generalized and powerful brushwork.

Sketching refers to the author's observation of objective things, the ability to understand, summarize and refine, and quickly realize objective things on drawing paper in a short period of time. Therefore, 1: the character sketch focuses on the description of the task dynamics (body posture) and the capture, 2:

Architectural and landscape sketches focus on the understanding and expression of the objective environment and the objective scene. The focus of the two sketches is different. Therefore.

The method of practice is also different. For example, the character first depends on whether the proportions of the human body structure are correct, and secondly, whether the lines are smooth

Architectural sketches focus on the grasp of perspective.
