Element Detail
PerpendicularPoint
A perpendicular point is given by a point and a line. It is determined by projecting the given point orthogonal onto the given line. This element should be used in GEONExTReader only. All other applications should use orthogonal projection Orthogonalprojection.
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "perpendicularpoint".

Possible parent array combinations are:
{JXG.Line} p
{JXG.Point} l

The constructed point is the orthogonal projection of p onto l.


Throws:
{Error}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
var p1 = board.create('point', [0.0, 4.0]);
var p2 = board.create('point', [6.0, 1.0]);
var l1 = board.create('line', [p1, p2]);
var p3 = board.create('point', [3.0, 3.0]);

var pp1 = board.create('perpendicularpoint', [p3, l1]);
