What is the composition of a point, line, and surface? What is the composition of a point, line, and

Point, line, and surfaceThe composition is the first basic unit of the plane composition, which is the composition of the three elements. Point in geometry.

In the sense that a point is visible, the smallest formal unit is a representation of a position, and there is only a position and no area. It is only when it is compared with the surrounding elements that it can be known whether this image with a specific area can be called a point, regardless of direction, size, shape, the point of the design is different from the point in the geometry.

The composition principle of points, lines, and surfaces

The smaller the composition of the point, the more it can give people the feeling of the point, and the mixed arrangement of different sizes and sparse makes it a scattered composition. The composition of the line is that the line is the trajectory of the point movement, the line, the line, the line that changes densely, that is, the line arranged at different distances, and the visual effect of the perspective space is different. The composition of the surface is that the surface reflects the full, thick, and overall stable visual effect, and the geometric surface of the surface.

The rules of expression are stable and more rational, and the contrast and unity in the plane composition are the basic rules of plane composition, which is equivalent to engaging in graphic design.

It is at the basic level of plane composition theory as well as the principle of plane composition, symmetry and equilibrium.

Dots, lines, and surfaces are the three most basic elements in the picture.

Plane composition is the visual elements on the two-dimensional plane, according to the visual effect of beauty, the principle of mechanics, the arrangement and combination, it is to create the image with reason and logical reasoning, the method of studying the arrangement between the image and the image is the product of the combination of reason and sensibility.

The plane composition is mainly composed of points, lines, and planes, and the private rhythm is rigorous, rich in abstraction and shape.

Convergence and dispersion of points

The aggregation and dispersion of points is based on the minimum two points, and the more points, the stronger the sense of aggregation. The evacuation and aggregation of points are relative.

The virtual and real, sparse, neat, balanced, repetitive, and mutated dots can all form different styles of works. There are many types of points: regular aggregation, irregular aggregation, and combination of regular aggregation and irregular aggregation.

Points, lines, and surfaces make up the plane.

Points, lines, and planes are concepts in geometry and are the basic elements of plane space. A point is a zero-dimensional object, and a point, as the simplest geometric concept, is often used as the most basic component in geometry, physics, vector graphics, and other fields. Points form lines, lines form surfaces, and points are the most basic components of geometry.

In the usual sense, points are treated as zero-dimensional objects, lines as one-dimensional objects, and faces as two-dimensional objects. The jog becomes a line, and the line moves into a surface.

The line is the trajectory of the point motion and the starting point of the surface motion. In geometry, a line only has a position and length, whereas in morphology, a line also has styling elements such as width, shape, color, texture, etc. During his lectures at the Bauhaus, the painter Klee gave the following definition:

A line is a point in motion.

More importantly, he vividly divides the line into three basic types: the positive line, the negative line, and the neutral line. Once a line has traced a coherent figure, it becomes a neutral line; If you color the figure again, then the line becomes a negative line again, because the color has already taken over the positive factor.

1. Point

In plastic arts, a point is a point with an area, a shape, a color, a concreteness, and an image. A point represents a position, which has neither length nor width and is the smallest unit. In planar composition, the concept of a point is only a relative, it exists in contrast, which is shown by comparison.

2. Line

The shapes of the lines are extremely rich, including straight lines, broken lines, curves, cross lines, etc., and they have a strong emotional and emotional expressiveness. A line is the trajectory of a point movement. In the geometric definition, a line has only a position and length, but not a wide slag thickness and thicknessFrom the perspective of plane composition, a line can have both length and width.

3. Surface

In the plastic arts, points, lines, and surfaces are relative, and surfaces are shapes that are larger than points and wider than lines. The surface is formed by the continuous movement of the line to the end of the mark. Faces have length, width, and no thickness, and straight lines move parallel to rectangles; Straight line rotation moves into a circle; Moving freely in a straight line to form an organic shape; Straight lines and arcs combine to form irregular shapes.

Characteristics of point, line, and surface:

Because the infinitesimal infinitesimal of the body, surface, and line (permanently greater than zero) is not equal to zero, the beam is destroyed and there is no limit. So, here we must not mistake the tangible point (of the theoretical application of Cavalliri and Kepler) into the microscopic realm for being equal to the intangible point. Invisible points can only be reflected through the contrast between positive, positive, and positive lines composed of tangible points and negative, negative, and negative lines.

The body (positive body and negative body): it is the collection of positive body points and positive body points to form a positive body; Negative points and a set of negative points form a negative body.

(positive and negative) in the surface: it is the set of positive points and positive points that form a positive one; The negative points and the set of negative points make up a negative.

Points, lines, and surfaces make up the plane. Points, lines, and planes are concepts in geometry and are the basic elements of plane space. Every art contains its own language, and the morphological elements of the composition of the language of plastic arts are:

Points, lines, surfaces, bodies, colors and textures, etc. A point is a zero-dimensional object, and a point is the simplest geometric concept, usually as the most basic component of geometry, physics, vector graphics, and other fields.

In geometry, topology, and mathematics, a point in space is used to describe a particular kind of object in a given space, in which there are analogues such as volume, area, length, or other high-dimensional analogues.

A point is a zero-dimensional object, and a point, as the simplest geometric concept, is usually used as the most basic component of geometry, physics, vector graphics, and other fields. Points form lines, lines form surfaces, and points are the most basic components of geometry.

(1) Composition of ordered points:This mainly refers to the shape and area, position or direction and other factors, arranged in a regular form, or the same repetition, or orderly gradients, etc.

The points are often arranged through sparse and dense arrangements to form the expression needs of the graphics in the space, and at the same time, the rich and orderly point composition will also produce a sense of space with delicate layers and form a three-dimensional. In the composition, the relationship between the points forms the whole, and their arrangement is combined with the space of the whole, so the visual tendency of the points is the line and surface, which is the rational composition of the points.

(2) Composition of free points:The shape, area, position or direction of the points are arranged in a free, irregular form, which often presents a rich, flat, and scattered visual effect. If you use this to represent parts of space, you can use them to their strengths, such as symbolizing the stars in the sky or as a decoration for the shading of graphics.

Lines are usually divided into the following two categories:

1. Straight lines: parallel lines, perpendicular lines (vertical lines), oblique lines, broken lines, dotted lines, zigzag lines, etc. The straight line is interpreted in "Cihai" as:

When a point moves in a certain (including reverse) direction on a plane or in space or in space, the trajectory formed is a straight line, and only one straight line can be drawn from two bright points.

2. Curves: arcs, parabolas, hyperbolas, circles, ripple lines (wavy lines), serpentine lines, etc. In Cihai, a curve is defined as a trajectory of a point that changes direction on a plane or in space due to certain conditions.

3. Line expressions.

Because the line itself has a strong generalization and expressiveness, the line, as the most basic language of plastic arts, has been paid attention to. In Chinese painting, there are various linear changes of "Eighteen Strokes", as well as the pursuit of linear charm such as "bone method with brush" and "pen breaking qi connection". Learning to draw always starts with lines, such as sketching and sketching, mostly in the form of lines.

In modeling, the line plays a vital role, it is not only the outline line that determines the shape of the object, but also can depict and express the internal structure of the object, for example, the line can outline the texture of the pattern, and it can even be said that the expression of the object can also be conveyed through the line.
