What are points, lines and surfaces?

The position of a point in space is a point, which is the basis of all graphics. Lines are connected by countless points, and countless lines intersect in the same plane to form a face.

As the simplest geometric concept, point is usually the most basic component in geometry, physics, vector graphics and other fields. Generally speaking, points are regarded as zero-dimensional objects, lines as one-dimensional objects and surfaces as two-dimensional objects. Points become lines, and lines become faces.

Extended data

Point, line and surface are the three basic elements in the picture. The three elements represent the picture through repetition, gradual change, emission and contrast. Without points, lines and surfaces, there is no graphic design.

Through the transformation between points, lines and surfaces, the picture structure is naturally displayed. How to understand and use the elements of point, line and surface well, enhance the aesthetic feeling of form and achieve the purpose of visual communication is of great significance to design.

In morphology, points also have modeling elements such as size, shape, color and texture. The illusion of dots, black and white dots with the same size on the paper, has a sense of expansion on the black background and a sense of contraction on the black background.

In morphology, lines also have modeling elements such as width, shape, color and texture. The shapes of abstract lines are divided into straight lines, curves, broken lines, oblique lines, spirals and irregular lines. Horizontal line arrangement gives people a sense of calm, comfort and stability, while vertical line arrangement has the characteristics of lofty, slender and solemn.

The repeated arrangement of curves such as wavy lines gives people a soft, elegant, warm, romantic, relaxed and beautiful feeling. Disconnecting has a feeling of excitement, anxiety and uneasiness. Spiral arrangement emphasizes the characteristics of tension, distortion, sharp noise, elasticity and rhythm.

Morphologically, human face also has modeling elements such as size, shape, color and texture, and at the same time, human face is the presentation of "image", so human face is "shape"

For example, a square is steady, steady and static, and a triangle is tight and sharp. Curved surfaces are round, oval and plum blossom, giving people a full, rich and soft feeling.
