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
- The coordinates are given as x, y, z consisting of numbers of functions and the text.
-
{array|function} F
{string} txt
- Alternatively, the coordinates can be supplied as array or function returning an array.
- 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();
