Element Detail
Mirrorpoint
A mirror point is determined by the reflection of a given point against another given point.
-
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create
with type "mirrorpoint".
- Possible parent array combinations are:
-
{JXG.Point} p1
{JXG.Point} p2
- The constructed point is the reflection of p2 against p1.
- Throws:
- {Error}
- If the element cannot be constructed with the given parent objects an exception is thrown.
- Examples:
var p1 = board.create('point', [3.0, 3.0]);
var p2 = board.create('point', [6.0, 1.0]);
var mp1 = board.create('mirrorpoint', [p1, p2]);
