-
Gets a value indicating whether or not all entities in the data source are ready
-
Gets the scene associated with this display.
Methods
-
Gets or sets the default function which creates an array of visualizers used for visualization. By default, this function uses all standard visualizers.
-
Destroys the WebGL resources held by this object. Destroying an object allows for deterministic release of WebGL resources, instead of relying on the garbage collector to destroy this object.
Once an object is destroyed, it should not be used; calling any function other thanisDestroyed
will result in aDeveloperError
exception. Therefore, assign the return value (undefined
) to the object as done in the example.Returns:
Throws:
-
DeveloperError : This object was destroyed, i.e., destroy() was called.
Example:
dataSourceDisplay = dataSourceDisplay.destroy();
See:

-
Returns true if this object was destroyed; otherwise, false.
If this object was destroyed, it should not be used; calling any function other thanisDestroyed
will result in aDeveloperError
exception.Returns:
True if this object was destroyed; otherwise, false. -
Updates the display to the provided time.
Name Type Description time
JulianDate The simulation time. Returns:
True if all data sources are ready to be displayed, false otherwise.
Type Definitions

Name Type Description scene
Scene The scene to create visualizers for. dataSource
