The definition of plane?

Question 1: The specific definition of plane angle is: a plane angle takes any point on the edge of a dihedral angle as the endpoint, so that two rays are perpendicular to the edge in two planes, which is called the plane angle of dihedral angle. In other words, if any point on the edge of dihedral angle makes the ray perpendicular to the edge in two half planes, the angle formed by these two rays is called the plane angle of dihedral angle. 1. The dihedral angle uses its plane angle. Let's say that the dihedral angle is how many degrees as the plane angle of the dihedral angle is. 2. The plane angle of dihedral angle has nothing to do with the position of point (or vertical plane), but only with the opening angle of dihedral angle.

Question 2: The definition of graphic design generally refers to artistry and professionalism, with "vision" as a way of communication and expression. Create and combine symbols, pictures and words in various ways for visual expression to convey ideas or information. Graphic designers may use professional skills such as typesetting, visual arts and page layout to achieve the purpose of creative planning. Graphic design can usually refer to the process of making (designing) and the final finished work.

(1) The process of processing some digitized images with some special operations.

(2) It is a comprehensive content integrating computer technology, digital technology and artistic creativity.

Definition of design: Design is an artistic creation activity based on business environment, which is different from the designer's art.. Design is a kind of work or occupation, and it is a modeling activity with aesthetic feeling, use and commemorative function.

Design is based on business and the public, and serves them, thus producing commercial value and artistic value, which is different from the appreciation range of individuals or some groups of art.

Graphic design classification

Graphic design (15 sheets) At present, the common graphic design projects can be summarized into ten categories: web design, packaging design, DM advertising design, poster design, print media advertising design, POP advertising design, sample design, book design, publication design and VI design.

basic concept

(1) graphic design

Graphic design is to express the author's thoughts in the form of pictures. Different basic graphics can be combined into patterns on the plane according to certain rules. You can also create by hand. Mainly in two-dimensional space, the boundary between the map and the ground is divided into contours to describe the image. The sense of space shown by graphic design is not a real three-dimensional space, but an illusion space formed by the visual guidance of graphics.

(B) Graphic design terminology

1. Harmony: In a narrow sense, harmonious graphic design is unity and contrast, and the two are not boring or chaotic. Broadly speaking, when judging the relationship between two or more elements or parts, the feelings and consciousness of each part are a whole coordinated relationship. 2. Contrast: also known as contrast, two elements with great qualitative or quantitative contrast are successfully arranged together, which makes people feel distinct and strong, has a sense of unity, makes the subject more distinct and works more active. 3. Symmetry: suppose a vertical line is set in the center of a graph, and the graph is divided into two equal parts, and the graphs of the left and right parts are completely equal. This is a symmetrical figure. 4. Balance: physically speaking, it refers to the weight relationship; In graphic design, it refers to the balance between distribution function and visual judgment according to the shape, size, weight, color and material of the image. 5. Proportion: refers to the quantitative relationship between parts or parts and the whole. Proportion is an important factor that constitutes the size of all units and the arrangement and combination of units in the design. 6. Center of gravity: The center of the picture is the center of vision. The change of the outline of the picture, the convergence and divergence of graphics, and the distribution of color or light and shade can all affect the visual center. 7. Sense of rhythm: sense of rhythm, with a sense of time, refers to the sense of movement generated when the same element is repeated in the composition design. 8. Rhythm: Simple unit combination and repetition tend to be monotonous in plane composition, and regularly changing images or color groups are arranged in a number ratio and equal proportion, thus generating a sense of melody of music and becoming rhythm.

(C) the elements of graphic design

1. Conceptual elements, the so-called conceptual elements, are those things that don't actually exist and can't be seen, but people's consciousness can feel them. For example, when we see a figure with sharp corners, we feel that there are some points on it and edge lines on the outline of the object. Conceptual elements include: point, line and surface. 2. Visual elements: conceptual elements will be meaningless if they are not reflected in the actual design. Conceptual elements are usually embodied by visual elements, which include the size, shape and color of graphics. 3. Relational elements: The organization and arrangement of visual elements on the screen are determined by relational elements. Including: direction, position, space, center of gravity, etc. 4. Practical elements: meaning, content, purpose and function of design. ...& gt& gt

Question 3: What is the definition of an airplane? I want to ask how a plane is two-dimensional in mathematics. The expression is a plane coordinate system, and any point on the plane can be expressed as (x, y).

Three points on the plane can define a circle.

Stereo is three-dimensional, and its expression form is spatial three-dimensional coordinate system, and any point can be expressed as (x, y, z).

Three points in space can determine a surface.

Question 4: What is the definition of building plan? Building plan

It is a horizontal cross-sectional view obtained by orthogonal projection of the rest of the house above the window sill, and the upper part is removed. Display the plane form, area size, room layout, building population, entrance hall and staircase layout of the building, and display the position, thickness and material of walls and columns, as well as the types and positions of doors and windows. The main drawings include the first floor plan, second floor plan or standard floor plan, top floor plan, roof plan, etc. Among them, the roof plan is a plan obtained by horizontal orthogonal projection of the roof shape above the house.

). Encyclopedia of China (Architecture? Garden? Urban planning volume (a few words). Beijing: Encyclopedia of China is published. ...

Question 5: The construction site plan is defined by horizontal projection method, corresponding to the legend. On the topographic map with contour lines or coordinate grids, the drawings of newly built, planned, original and demolished buildings and structures are called the general plan.

Question 6: What is the definition of print advertising? As far as its form is concerned, print advertising is just a way to convey information, a medium between advertisers and audiences, and its result is to achieve certain commercial or political purposes. In countries with rapid economic development, advertising is indispensable. Of course, as a special product of modern human life, there are different opinions, but we should face up to the fact that in daily life, we may receive advertising information at any time, and we will see advertisements everywhere when we open newspapers, turn on TV and surf the Internet. It can be said that it has penetrated into all aspects of our lives. People in modern cities are used to such a life.

Modern advertising has developed since the middle of19th century, with a history of one hundred years. After industrial revolution in europe, with the development of printing technology, rigid color separation printing technology of color slate and screen was widely used. The rapid development of economy has brought about the prosperity of the market, and people's demand for advertisements has also greatly increased, which has laid the foundation for the rise of modern advertisements. With the emergence of radio and television, the forms of advertisements are diversified and three-dimensional. Nowadays, advertising has matured in developed countries and has formed a complete system in theory and practice, which plays an important role in economic and political life. Faced with numerous advertising forms, a professional engaged in graphic design should have a basic understanding of advertising as a whole, so as to grasp the characteristics of different advertising forms and give full play to their respective advantages.

Generally speaking, advertisements can be divided into media advertisements and non-media advertisements. Media advertisements refer to advertisements that spread information through the media, such as TV advertisements, newspaper advertisements, radio advertisements and magazine advertisements. Non-media advertising refers to the forms of advertising media directly facing the audience, such as street sign advertising, plane poster advertising, point-of-purchase advertising in commercial environment, etc. Different advertising forms have different design requirements.

Graphic advertising design plays an important role in non-media advertising, and it is also a course that must be mastered in learning graphic design, both in form and content. The forms of expression can be varied, unlike painting, which is not limited by a certain media. Painting, photography, collage, I can use all kinds of forms, realism, freehand brushwork, abstraction, and various means have their own strengths. This is not because print advertising design has distinct personality, because advertising creation is a fashion art, and its works should reflect the trend of the times. Designers should keep professional sensitivity, absorb nutrition from different art forms, and create works that conform to popular aesthetics and the trend of the times. Advertising is also very extensive in content, ranging from national policies to a commodity, which can be the object of performance. The specific content can be political propaganda, environmental protection, culture and sports, film and television dramas, drinks and food, household appliances, tourism and so on. This list can be a lot, and it seems a bit complicated. I also try to divide the content into several categories, such as culture and commodities. In fact, when we face an advertising work, you will find that the content is not independent. For example, commodity advertisements can be advertised from the perspective of the environment. So there is no need to divide the content too clearly. If we put a specific content in a fixed range, it may limit our creative thinking. The reason for listing this way is to illustrate the scope of print advertising design, which pays attention to people's lives from different angles, which is why we say that it plays an important role in non-media advertising.

After a preliminary understanding of the nature, form and content of print advertisements, we should understand their basic creative laws. Generally speaking, print advertising creation includes two aspects, namely creativity and performance. Creativity refers to thinking ability, and performance refers to modeling ability. They are different in concept, but they are unified in the process of creation. There is a simple reason. Only one idea, no modeling ability. No matter how good the idea is, it is impossible to show it. On the other hand, without creativity and aesthetic consciousness, its idea is absurd and infeasible. In addition, it can't be called advertising design only by modeling ability and lack of creative thinking, because advertising has strong functionality, and its most basic function is to convey information. How to convey this information reflects the ability of creative thinking. Modern advertising is not only a simple informing function, but also a unique creative thinking and proper expression, which is the key to the success of advertising. Therefore, there are both differences and unity between them, and the cultivation of these two abilities is very professional. ...& gt& gt
