Element Detail
Point3D
A Point3D object is defined by 3 coordinates [x,y,z].

All numbers can also be provided as functions returning a number.

This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "point3d".

Possible parent array combinations are:
{number|function} x
{number|function} y
{number|function} z

The coordinates are given as x, y, z consisting of numbers of functions.


{array|function} F

Alternatively, the coordinates can be supplied as
  • array arr=[x,y,z] of length 3 consisting of numbers or
  • function returning an array [x,y,z] of length 3 of numbers.


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
   var bound = [-5, 5];
   var view = board.create('view3d',
       [[-6, -3], [8, 8],
       [bound, bound, bound]],
       {});
   var p = view.create('point3d', [1, 2, 2], { name:'A', size: 5 });
   var q = view.create('point3d', function() { return [p.X(), p.Y(), p.Z() - 3]; }, { name:'B', size: 5, fixed: true });


				
                
Field Detail
<private> {Array} coords
Homogeneous coordinates of a Point3D, i.e. array of length 4: [w, x, y, z]. Usually, w=1 for finite points and w=0 for points which are infinitely far.
  p.coords;

<private> {JXG.GeometryElement3D} slide
Optional slide element, i.e. element the Point3D lives on.
  p.slide;
Default Value:
null
Method Detail
<private> <static> Point3D.F()
Function or array of functions or array of numbers defining the coordinates of the point, used in updateCoords.
See:
updateCoords

<private> <static> {Object} Point3D.normalizeCoords()
Normalize homogeneous coordinates such the the first coordinate (the w-coordinate is equal to 1 or 0)-
Returns:
{Object} Reference to the Point3D object
Examples:
   p.normalizeCoords();

<static> {Object} Point3D.setPosition(coords, noevent)
Set the position of a 3D point.
Parameters:
{Array} coords
3D coordinates. Either of the form [x,y,z] (Euclidean) or [w,x,y,z] (homogeneous).
{Boolean} noevent Optional
If true, no events are triggered.
Returns:
{Object} Reference to the Point3D object
Examples:
   p.setPosition([1, 3, 4]);

<private> <static> {Object} Point3D.updateCoords()
Update the the homogeneous coords array.
Returns:
{Object} Reference to the Point3D object
Examples:
   p.updateCoords();

<static> {Number} Point3D.X()
Get x-coordinate of a 3D point.
Returns:
{Number}
Examples:
  p.X();

<static> Point3D.Y()
Get y-coordinate of a 3D point.
Returns:
Number
Examples:
  p.Y();

<static> Point3D.Z()
Get z-coordinate of a 3D point.
Returns:
Number
Examples:
  p.Z();
