Perspective Projections

• Used for:

  • advertising

  • presentation drawings for architecture, industrial design, engineering

  • fine art

• Pros:

  • gives a realistic view and feeling for three dimensional form of object

• Cons:

  • does not preserve shape of object or scale (except where object intersects projection plane)

• Different from a parallel projection because

  • parallel lines not parallel to the projection plane converge

  • size of the object is diminished with distance

  • foreshortening is not uniform.
