Points, lines and surfaces form a plane.

Specifically, the dots of the image can be represented by various tools. Dots of different shapes present different visual effects. As their area increases, the feeling of the dots will also weaken. For example, when we look down at the pedestrians on the street from a high altitude, we have a "point" feeling. When we return to the ground, the "point" feeling disappears.

In the picture space, on the one hand, the point has a strong centripetality, which can form the visual focus and the center of the picture, showing the positive side of the point; on the other hand, the point can also make the picture space appear. The scattered and chaotic state shows the negativity of dots, which is also an issue worth noting when using dots in practice.

Points also have explicit and recessive characteristics. Recessive points exist at the intersection of two lines, the top or end of a line, etc.
