3-D rendering without using a camera. Generally, pictorial drawings show three sides of the object. However, because of distortion created by the angle and distance it is not possible to build an object from a pictorial drawing. There are three main types.

  1. Isometric-In an isometric drawing the object is rotated and drawn such that all sides visible have equal distortion.
  2. Oblique-In an oblique drawing, the object is drawn to show a non-distorted front view. An example of an oblique drawing is Mickey Mouse. Notice that no matter how or where you look his face appears round.
  3. Perspective- A perspective drawing shows an objects natural view. A perspective drawing shows what the object will look like when finished but can not be used to construct the object because there is no way to measure the distortion.
