Two Point Perspective
Two point perspective provides a great amount of flexibility for designers and visual communicators. This framework of perspective allows an object or environment to be drawn from unique viewpoints and can be arranged so that three external surfaces can be shown at the one time. Although two point perspective is somewhat more difficult to master it can provide more interesting illustrations relevant to human experience.

There are 2 two point perspective frameworks that can be used to construct a two point perspective drawing; Three-line two point projection and two-line two point perspective. Each framework has its own benefits and either can be used depending on their suitability for the final illustration desired.
Three-line Two Point Perspective
Three-line Two Point Perspective or Formal Two Point Perspective is based on the idea of two vertical vanishing lines intersecting one horizontal vanishing line.
Two-Line Two Point Perspective
Two-line Two Point Perspective is based on the idea of one vertical vanishing line intersecting one horizontal vanishing line. The framework does use a second Vanishing Point but does not recognise the Vertical Vanishing Line as it is located far away off the drawing material.
