  1. Circles in Perspective - Elliptical Shapes

  2. Major Axis Minor Axis In the visual world, circular objects rarely appear as circles. Most commonly, an observed circle will appear as an ellipse.

  3. An ellipse is a continuous curve, compressed along one axis. It is bilaterally symmetrical.

  4. At eye level, the circle will appear to be a straight line. The further the circle from eye level, the more open the ellipse. When circles are parallel to the ground plane, the major axis of the ellipse is always horizontal to the viewer. Eye Level

  5. Drawing a central axis promotes symmetry in cylindrical forms. Drawing an ellipse is easier if you do not stop the pencil until you have gone around the ellipse several times.

  6. The major axis of a foreshortened cylindrical cross section will intersect the central axis at a precise right angle.

  7. Ellipse (flat) Foreshortened Circle(spatial illusion) The center of a foreshortened circle is always closer to the back edge.

  8. In order to prevent distortion, artists need to be sensitive to the conflict between “what they know” and “what they see”.
