homeButton	boolean	<可选>	true	If set to false, the HomeButton widget will not be created.
infoBox	boolean	<可选>	true	If set to false, the InfoBox widget will not be created.
sceneModePicker	boolean	<可选>	true	If set to false, the SceneModePicker widget will not be created.
selectionIndicator	boolean	<可选>	true	If set to false, the SelectionIndicator widget will not be created.
timeline	boolean	<可选>	true	If set to false, the Timeline widget will not be created.
navigationHelpButton	boolean	<可选>	true	If set to false, the navigation help button will not be created.
navigationInstructionsInitiallyVisible	boolean	<可选>	true	True if the navigation instructions should initially be visible, or false if the should not be shown until the user explicitly clicks the button.
scene3DOnly	boolean	<可选>	false	When true, each geometry instance will only be rendered in 3D to save GPU memory.
shouldAnimate	boolean	<可选>	false	true if the clock should attempt to advance simulation time by default, false otherwise. This option takes precedence over setting Viewer#clockViewModel.
clockViewModel	ClockViewModel	<可选>	new ClockViewModel(clock)	The clock view model to use to control current time.
selectedImageryProviderViewModel	ProviderViewModel	<可选>		The view model for the current base imagery layer, if not supplied the first available base layer is used. This value is only valid if `baseLayerPicker` is set to true.
imageryProviderViewModels	Array.<ProviderViewModel>	<可选>	createDefaultImageryProviderViewModels()	The array of ProviderViewModels to be selectable from the BaseLayerPicker. This value is only valid if `baseLayerPicker` is set to true.
selectedTerrainProviderViewModel	ProviderViewModel	<可选>		The view model for the current base terrain layer, if not supplied the first available base layer is used. This value is only valid if `baseLayerPicker` is set to true.
terrainProviderViewModels	Array.<ProviderViewModel>	<可选>	createDefaultTerrainProviderViewModels()	The array of ProviderViewModels to be selectable from the BaseLayerPicker. This value is only valid if `baseLayerPicker` is set to true.
baseLayer	ImageryLayer | false	<可选>	ImageryLayer.fromWorldImagery()	The bottommost imagery layer applied to the globe. If set to false, no imagery provider will be added. This value is only valid if `baseLayerPicker` is set to false.
ellipsoid	Ellipsoid	<可选>	Ellipsoid.default	The default ellipsoid.
terrainProvider	TerrainProvider	<可选>	new EllipsoidTerrainProvider()	The terrain provider to use
terrain	Terrain	<可选>		A terrain object which handles asynchronous terrain provider. Can only specify if options.terrainProvider is undefined.
skyBox	SkyBox | false	<可选>		The skybox used to render the stars. When undefined and the WGS84 ellipsoid used, the default stars are used. If set to false, no skyBox, Sun, or Moon will be added.
skyAtmosphere	SkyAtmosphere | false	<可选>		Blue sky, and the glow around the Earth's limb. Enabled when the WGS84 ellipsoid used. Set to false to turn it off.
fullscreenElement	Element | string	<可选>	document.body	The element or id to be placed into fullscreen mode when the full screen button is pressed.
useDefaultRenderLoop	boolean	<可选>	true	True if this widget should control the render loop, false otherwise.
targetFrameRate	number	<可选>		The target frame rate when using the default render loop.
showRenderLoopErrors	boolean	<可选>	true	If true, this widget will automatically display an HTML panel to the user containing the error, if a render loop error occurs.
useBrowserRecommendedResolution	boolean	<可选>	true	If true, render at the browser's recommended resolution and ignore window.devicePixelRatio.
automaticallyTrackDataSourceClocks	boolean	<可选>	true	If true, this widget will automatically track the clock settings of newly added DataSources, updating if the DataSource's clock changes. Set this to false if you want to configure the clock independently.
contextOptions	ContextOptions	<可选>		Context and WebGL creation properties passed to Scene.
sceneMode	SceneMode	<可选>	SceneMode.SCENE3D	The initial scene mode.
mapProjection	MapProjection	<可选>	new GeographicProjection(options.ellipsoid)	The map projection to use in 2D and Columbus View modes.
globe	Globe | false	<可选>	new Globe(options.ellipsoid)	The globe to use in the scene. If set to false, no globe will be added and the sky atmosphere will be hidden by default.
orderIndependentTranslucency	boolean	<可选>	true	If true and the configuration supports it, use order independent translucency.
creditContainer	Element | string	<可选>		The DOM element or ID that will contain the CreditDisplay. If not specified, the credits are added to the bottom of the widget itself.
creditViewport	Element | string	<可选>		The DOM element or ID that will contain the credit pop up created by the CreditDisplay. If not specified, it will appear over the widget itself.
dataSources	DataSourceCollection	<可选>	new DataSourceCollection()	The collection of data sources visualized by the widget. If this parameter is provided, the instance is assumed to be owned by the caller and will not be destroyed when the viewer is destroyed.
shadows	boolean	<可选>	false	Determines if shadows are cast by light sources.
terrainShadows	ShadowMode	<可选>	ShadowMode.RECEIVE_ONLY	Determines if the terrain casts or receives shadows from light sources.
mapMode2D	MapMode2D	<可选>	MapMode2D.INFINITE_SCROLL	Determines if the 2D map is rotatable or can be scrolled infinitely in the horizontal direction.
projectionPicker	boolean	<可选>	false	If set to true, the ProjectionPicker widget will be created.
blurActiveElementOnCanvasFocus	boolean	<可选>	true	If true, the active element will blur when the viewer's canvas is clicked. Setting this to false is useful for cases when the canvas is clicked only for retrieving position or an entity data without actually meaning to set the canvas to be the active element.
requestRenderMode	boolean	<可选>	false	If true, rendering a frame will only occur when needed as determined by changes within the scene. Enabling reduces the CPU/GPU usage of your application and uses less battery on mobile, but requires using Scene#requestRender to render a new frame explicitly in this mode. This will be necessary in many cases after making changes to the scene in other parts of the API. See Improving Performance with Explicit Rendering.
maximumRenderTimeChange	number	<可选>	0.0	If requestRenderMode is true, this value defines the maximum change in simulation time allowed before a render is requested. See Improving Performance with Explicit Rendering.
depthPlaneEllipsoidOffset	number	<可选>	0.0	Adjust the DepthPlane to address rendering artefacts below ellipsoid zero elevation.
msaaSamples	number	<可选>	4	If provided, this value controls the rate of multisample antialiasing. Typical multisampling rates are 2, 4, and sometimes 8 samples per pixel. Higher sampling rates of MSAA may impact performance in exchange for improved visual quality. This value only applies to WebGL2 contexts that support multisample render targets. Set to 1 to disable MSAA.
