How it works
This vanishing point art with labels names the horizon line, the vanishing point and the orthogonal, transversal and vertical lines of a one-point drawing. A two-point box adds a left and a right vanishing point and the leading edge.

One point: the railroad track
The horizon line is the viewer's eye level. The two rails are parallel on the ground, yet they are drawn running to one dot on that line: the vanishing point. Lines that run to it are orthogonal lines. The ties across the track are transversal lines, and the posts are vertical lines.
Two points: the box
The box is turned so that a corner faces you. Its nearest upright edge is the leading edge. From there the left side runs back to one vanishing point and the right side to another, both on the horizon line.
- The box sits below the horizon line, so its edges angle up to the line and its top shows.
Questions and answers
What is a vanishing point in art?
It is the point in a perspective drawing where lines that run away from the viewer appear to meet. Railroad rails are parallel, yet they are drawn meeting at a vanishing point on the horizon line.
What is the horizon line in a perspective drawing?
The horizon line is a level line that stands for the viewer's eye level. The vanishing points of level lines, such as rails and the edges of a box, lie on it.
What are orthogonal lines?
Orthogonal lines are the lines in a perspective drawing that run back to the vanishing point. On the railroad drawing they are the two rails and the dashed lines through the tops and feet of the posts.
What is the difference between one-point and two-point perspective?
A one-point drawing has a single vanishing point, as on the railroad track. A two-point drawing has two, both on the horizon line: the left side of the box runs to one and the right side to the other.
