This class is an implementation of WebGL render engine. It presents a geo position (from a view model) in a 3D scene, where all layers are rendered in the order in which they are provided.

Methods
-
addEventListener (type, handler, opt_capture, opt_scope) inherited
-
This method adds a listener for a specific event.
Note that to prevent potential memory leaks, you must either call
removeEventListenerordisposeon the given object when you no longer need it. -
addOnDisposeCallback (callback, opt_scope) inherited
-
This method adds a callback which is triggered when the
EventTargetobject is being disposed.Name Type Description callbackfunction The callback function.
opt_scopeObject optional An optional scope for the callback function
-
dispatchEvent (evt) inherited
-
This method dispatches an event on the
EventTargetobject.Name Type Description evtH.util.Event | string An object representing the event or a string with the event name
-
dispose () inherited
-
This method removes listeners from the given object. Classes that extend
EventTargetmay need to override this method in order to remove references to DOM Elements and additional listeners. -
This method retrieves the projected world coordinates corresponding to the geographical coordinates supplied by the caller.
Name Type Description geoPointH.geo.IPoint An object containing the geographical coordinates.
Returns:
Type Description Object An object representing the results of the conversion to the world coordinates. -
This method was previously retrieving the current animation duration. Now it's deprecated and always returns
undefined. -
This method was previously retrieving the current animation easing. Now it's deprecated and always returns
undefined. -
metersToGeo (point)H.geo.IPoint
-
This method retrieves the geographical coordinates corresponding to the projected world coordinates supplied by the caller.
Name Type Description pointObject An object defining a location in meters.
Returns:
Type Description H.geo.IPoint An object representing the results of conversion to a geographical location. -
removeEventListener (type, handler, opt_capture, opt_scope) inherited
-
This method removes a previously added listener from the
EventTargetinstance. -
This method was previously used to reset animation settings on the render engine to defaults. Now it's deprecated and doesn't change animation behavior.
-
This method was previously setting the duration for all animations run by the render engine. Now it's deprecated and doesn't change animation behavior.
-
This method was previously setting a value indicating the easing to apply to animations run by the render engine. Now it's deprecated and doesn't change animation behavior.
Type Definitions
-
Options that can be used to initialize a new instance of the RenderEngine.
Properties:
Events
-
render inherited
-
Fired when one of the layers or the engine (all layers) has been rendered completely. The event target references either the completed layer or the render engine itself.
