1, 2 ,3 pt perspective.

1pt perspective

Dictionary.com define one point perspective as:

…a mathematical system for representing three-dimensional objects and space on a two-dimensional surface by means of intersecting lines that are drawn vertically and horizontally and that radiate from one point on a horizon line…

Although this definition sounds complicated, the concept is relatively simple. One point perspective is a drawing method that shows how things appear to get smaller as they get further away, converging towards a single ‘vanishing point’ on the horizon line. It is a way of drawing objects upon a flat piece of paper (or other drawing surface) so that they look three-dimensional and realistic.

Drawing in one point perspective is usually appropriate when the subject is viewed ‘front-on’ (such as when looking directly at the face of a cube or the wall of building) or when looking directly down something long, like a road or railway track. It is popular drawing method with architects and illustrators, especially when drawing room interiors.

2pt perspective

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.

3pt perspective

Whenever you need to realistically render a large exterior scene, or a very intricate interior, this is the perspective style to go with. Please note that due to the additional vanishing point, compared to the two point perspective, this style is more time consuming and should only be considered for final concept presentation. As opposed to the one and two point perspectives, the three point perspective, with the added third vanishing point, offers you the ability to create a very dramatic image, but with this ability comes the risk of wasting time in the process. I strongly recommend you invest some time and practice before you decide to use this technique on a deadline.
