Element Detail
Text3D
A Text3D object is defined by 3 coordinates [x, y, z, text] or an array / function for the position of the text and a string or function defining the text.

That is, all numbers can also be provided as functions returning a number.

At the time being, text display is independent from the camera view.

This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "text3d".
Possible parent array combinations are:
{number|function} x
{number|function} y
{number|function} z
{String|function} txt
{JXG.GeometryElement3D} [slide=undefined]
  The coordinates are given as x, y, z consisting of numbers of functions and the text. If an optional 3D element "slide" is supplied, the point is a glider on that element.
  F,txt,[slide=undefined] Alternatively, the coordinates can be supplied as array or function returning an array. If an optional 3D element "slide" is supplied, the point is a glider on that element.

Throws:
{Exception}
  If the element cannot be constructed with the given parent objects an exception is thrown.

Examples:

        var bound = [-4, 6];
        var view = board.create('view3d',
            [[-4, -3], [8, 8],
            [bound, bound, bound]],
            {
                projection: 'central'
            });

        var txt1 = view.create('text3d', [[1, 2, 1], 'hello'], {
            fontSize: 20,
        });

Method Detail
<private> <static> {Object} Text3D.normalizeCoords()
Normalize homogeneous coordinates such the the first coordinate (the w-coordinate is equal to 1 or 0)-

Returns:
  {Object} Reference to the Text3D object

Examples:

       p.normalizeCoords();

<static> {Object} Text3D.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 Text3D object

Examples:

       p.setPosition([1, 3, 4]);

<private> <static> {Object} Text3D.updateCoords()
Update the homogeneous coords array.

Returns:
  {Object} Reference to the Text3D object

Examples:

       p.updateCoords();
