Element Ellipse

JXG.GeometryElement
   ↳ JXG.Curve
         ↳ Ellipse

This element is used to provide a constructor for an ellipse. An ellipse is given by two points (the foci) and a third point on the the ellipse or the length of the major axis.

Defined in: Conic.js.
Extends JXG.Curve.

Element Summary
Constructor Attributes Constructor Name and Description
 
Element Detail
Ellipse
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "ellipse".

Possible parent array combinations are:
{JXG.Point|array} point1
{JXG.Point|array} point2
{JXG.Point|array} point3

Parent elements can be three elements either of type JXG.Point or array of numbers describing the coordinates of a point. In the latter case the point will be constructed automatically as a fixed invisible point.


{JXG.Point|array} point1
{JXG.Point|array} point2
{number|function} number

Parent elements can be two elements either of type JXG.Point or array of numbers describing the coordinates of a point. The third parameter is a number/function which defines the length of the major axis Optional parameters four and five are numbers which define the curve length (e.g. start/end). Default values are -pi and pi.


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
// Create an Ellipse by three points
var A = board.create('point', [-1,4]);
var B = board.create('point', [-1,-4]);
var C = board.create('point', [1,1]);
var el = board.create('ellipse',[A,B,C]);
