Class Detail
OtherIntersection(el1,el2,p)
An intersection point is a point which lives on two Lines or Circles or one Line and one Circle at the same time, i.e.
an intersection point of the two elements. Additionally, one intersection point is provided. The function returns the other intersection point.
- Parameters:
- {JXG.Line|JXG.Circle_JXG.Line|JXG.Circle_JXG.Point} el1,el2,p
- The result will be a intersection point on el1 and el2. i determines the intersection point different from p:
- Throws:
- {Exception}
- If the element cannot be constructed with the given parent objects an exception is thrown.
- Examples:
// Create an intersection point of circle and line var p1 = board.create('point', [2.0, 2.0]); var c1 = board.create('circle', [p1, 2.0]); var p2 = board.create('point', [2.0, 2.0]); var p3 = board.create('point', [2.0, 2.0]); var l1 = board.create('line', [p2, p3]); var i = board.create('intersection', [c1, l1, 0]); var j = board.create('otherintersection', [c1, l1, i]);
