The knowledge point of one-point perspective is

One-point perspective:

The parallel perspective of a regular hexahedron can see at least one face and at most three faces. The line segments of regular hexahedron drawing include horizontal lines, vertical lines and vanishing lines. The perspective directions of the three sets of edges are: four edges are parallel to the picture, four edges are perpendicular to the picture, and four edges disappear towards the main point.

Parallel perspective is also called one-point perspective. We usually see the front side of an object, and this side is parallel to our perspective. Due to the deformation of the perspective angle, the feeling of nearness and distance is produced, and perspective lines and vanishing points emerge as the times require.

According to the distance between each object and the viewer, draw the front surface (length and width) of the object on the screen, and then draw the front surface of each object according to the depth of each object. Because the scenery is large near and small at a distance, objects located nearby occupy a larger area of ??the screen. Objects located far away will gradually shrink according to their distance from the viewer until they disappear from the viewer's sight. A typical example of balanced perspective is the phenomenon of railway tracks or roads extending forward and disappearing into the horizontal line.
