Short note: Two-point perspective projection

Short answer

In two-point perspective, the view plane is parallel to one principal axis (usually vertical). Lines parallel to x and z axes converge to two vanishing points on the horizon; vertical lines stay vertical. It shows two faces of an object at an angle, more realistic than one-point perspective, used in architectural drawings.

Write a short note on two-point perspective projection.

Two-point perspective is a perspective projection in which the view plane is parallel to one principal axis (usually the vertical y-axis) and cuts the other two axes. Lines parallel to the x- and z-axes converge to two vanishing points on the horizon line, while vertical lines stay vertical and parallel.

           \    |      |    /
                |______|

Points:

  • It is obtained by rotating the object about the vertical axis so that its corner faces the viewer.
  • It is more realistic than one-point perspective and shows two faces of a box at an angle.
  • Vanishing points lie on the horizon at eye level.
  • If the view plane cuts all three axes, three vanishing points result (three-point perspective).
  • Used in architecture, interior design and industrial design drawings.
