    Ovals have straight sides and are made by connecting two circles.

                                                                                                   
                                                                                                       perimeters are constantly curved according to
                                                                                                       a mathematical formula.


                                                                                                      Ellipses are circles drawn in perspective.
    Think of a model rail road track with straight-aways or an oval above ground swimming pool.
What we know…

   Cups, plates, saucers, glasses, and many other
   forms are circles.
What we see …

    As we change our
    point of view, how
    we see the circle
    changes to ellipses
    of different widths.

    Here is a lamp shade
    viewed from above,
    on, and below the
    horizon line.
Ellipse Angles
   Tips:

   •Observe the shapes of the
   negative spaces surrounding the
   ellipses. This can help you with
   the correct curves and angles.

   •Avoid the tendency to make a
   straight line across the bottoms of
   vases, cups and glasses.

   •Keep the curve all the way
   around the ellipse, avoiding
   pointed ends.

   •Ellipses have no straight edges.

Minor & Major axes
   An ellipse has two axes we need to know about, the minor axis and the major
   axis. The minor axis divides the ellipse into two equal halves across its
   narrow dimension. The major axis divides the ellipse across its long
   dimension into two equal halves. The minor and major axes cross each other
   at a 90 degree angle.




                                                             90 degree angle
Divide a receding plane
   Dividing a flat plane will give you equal sized
   sections. Use this method to place evenly spaced
   objects.

   Note how the ellipse recedes toward the vanishing
   point.
