Lens.Coordinate.DEPTH ARCore/coordinate.js, line 258

Coordinate frame of the depth camera. Units are pixels.

Lens.Coordinate.getWindowOffset ARCore/coordinate.js, line 246

Returns the offset between window coordinates and projector coordinates.

Lens.Coordinate.HD ARCore/coordinate.js, line 252

Coordinate frame of the HD camera. Units are pixels.

Lens.Coordinate.PROJECTOR ARCore/coordinate.js, line 264

Coordinate frame of the projector/page. Units are pixels.

Lens.Coordinate.WINDOW ARCore/coordinate.js, line 274

Coordinate frame of the DOM window. For top-level apps, this is the same as the projector coordinate frame. For embedded Lens apps, this can be used to translate coordinates in the frame of the parent app (projector coordinates) to the frame of the child app (window coordinates).

Lens.Coordinate.WORLD ARCore/coordinate.js, line 280

Coordinate frame of the depth camera. Units are millimeters.

Static Methods

Lens.Coordinate.forElement(el) → {Array} ARCore/coordinate.js, line 216

Returns the coordinates for the bounding box of an element. Does not take into account CSS transforms. Throws an error if given a CSS selector that does not match any elements, or a jQuery object with no elements.

Argument	Type	Description
el	Element | String | jQuery	A DOM element, CSS selector, or jQuery object. This element must be rendered to the screen; it can't have been hidden with display: none in CSS or with jQuery's .hide().

Returns:

A 2-element array whose first element is the top left corner of the element and whose second element is the bottom right corner.

Instance Properties

system: System

The coordinate system, such as Lens.Coordinate.PROJECTOR.

x: Number

X coordinate.

y: Number

Y coordinate.

z: Number

Z coordinate, or undefined.

Instance Methods

transform(system, callback) → {Promise} ARCore/coordinate.js, line 123

Transforms this Coordinate to a Coordinate in a different system.

Argument	Type	Attributes	Description
system	String		The system to transform to, such as Lens.Coordinate.WORLD
callback	function	<optional>	A function to call with the transformed coordinate.

Returns:

A jQuery promise. You can attach callbacks using this promise or use jQuery's tools to do parallel transformations. If you passed a callback, that callback will automatically be registered as a completion handler for this promise.
