Transcript of 2 point perspective drawing

What is it?
Two point perspective drawing is a type of linear perspective. Linear perspective is a method using lines to create the illusion of space on a 2D surface.

There are three types of linear perspective.

One point
perspective uses one vanishing point placed on the horizon line.
Two point
perspective uses two points placed on the horizon line.
Three point
perspective uses three vanishing points.
Linear Perspective
Linear perspective is one of the six ways to create the illusion of space on a two-dimensional surface. All forms of linear perspective involve the horizon line, vanishing point(s), and lines of perspective that recede or advance to the vanishing point(s).

Each form of linear perspective is named for the number of
vanishing points
used in the drawing. Therefore,
two point perspective uses two vanishing points.
How it works
Two point perspective starts by defining the horizon line. This line theoretically represents the line that divides the sky from the ground. However, with many perspective drawings, this line is implied and instead represents the eye-line or "line of sight" of the viewer.
With two point perspective, two vanishing points are placed on the horizon line. These two points should be spaced out from each other to prevent distortion. Both vanishing points need not both be within the picture plane, just as long as they are found on the horizon line, which continues on off of the picture plane in both directions.
The next step is to draw the corner of the object. Most commonly, two point perspective is used for drawing buildings or interiors, so this line could be the corner of a building. This line is drawn in between the two vanishing points and can cross over the horizon line.
Below the Horizon Line
For forms placed below the horizon line the steps remain the same. However, the top of the form will be visible. This means that the top portion of the form will be defined by the orthogonal lines that extend from each end to the opposite vanishing point.
Above the Horizon Line
For forms placed above the horizon line, the same steps are followed. In this case, the bottom portion of the form is now visible to the viewer. The bottom portion is defined by extending lines from each end of the cube to the opposite vanishing point.
2 point perspective drawing
Receding lines are next drawn from each end of the corner to each one of the vanishing points. These lines are called orthogonal lines. Any set of parallel lines that recede away from the viewer will follow along these lines to one of the vanishing points.
