Globe

Members

depthTestAgainstTerrain :Boolean

True if primitives such as billboards, polylines, labels, etc. should be depth-tested against the terrain surface, or false if such primitives should always be drawn on top of terrain unless they're on the opposite side of the globe. The disadvantage of depth testing primitives against terrain is that slight numerical noise or terrain level-of-detail switched can sometimes make a primitive that should be on the surface disappear underneath it.

Default Value: false

Source: Scene/Globe.js, line 213

ellipsoid :Ellipsoid

Gets an ellipsoid describing the shape of this globe.

Source: Scene/Globe.js, line 291

enableLighting :Boolean

Enable lighting the globe with the sun as a light source.

Default Value: false

Source: Scene/Globe.js, line 241

imageryLayers :ImageryLayerCollection

Gets the collection of image layers that will be rendered on this globe.

Source: Scene/Globe.js, line 302

lightingFadeInDistance :Number

The distance where lighting resumes. This only takes effect when enableLighting is true.

Default Value: 9000000.0

Source: Scene/Globe.js, line 260

lightingFadeOutDistance :Number

The distance where everything becomes lit. This only takes effect when enableLighting is true.

Default Value: 6500000.0

Source: Scene/Globe.js, line 251

maximumScreenSpaceError :Number

The maximum screen-space error used to drive level-of-detail refinement. Higher values will provide better performance but lower visual quality.

Default Value: 2

Source: Scene/Globe.js, line 222

northPoleColor :Cartesian3

Determines the color of the north pole. If the day tile provider imagery does not extend over the north pole, it will be filled with this color before applying lighting.

Default Value: Cartesian3(2.0 / 255.0, 6.0 / 255.0, 18.0 / 255.0)

Source: Scene/Globe.js, line 173

oceanNormalMapUrl :String

The normal map to use for rendering waves in the ocean. Setting this property will only have an effect if the configured terrain provider includes a water mask.

Default Value: buildModuleUrl('Assets/Textures/waterNormalsSmall.jpg')

Source: Scene/Globe.js, line 201

show :Boolean

Determines if the globe will be shown.

Default Value: true

Source: Scene/Globe.js, line 190

southPoleColor :Cartesian3

Determines the color of the south pole. If the day tile provider imagery does not extend over the south pole, it will be filled with this color before applying lighting.

Default Value: Cartesian3(1.0, 1.0, 1.0)

Source: Scene/Globe.js, line 182

terrainProvider :TerrainProvider

The terrain provider providing surface geometry for this globe.

Source: Scene/Globe.js, line 123

tileCacheSize :Number

The size of the terrain tile cache, expressed as a number of tiles. Any additional tiles beyond this number will be freed, as long as they aren't needed for rendering this frame. A larger number will consume more memory but will show detail faster when, for example, zooming out and then back in.

Default Value: 100

Methods

destroy() → undefined

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 than isDestroyed will result in a DeveloperError 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:

globe = globe && globe.destroy();

See:

• Globe#isDestroyed

Source: Scene/Globe.js, line 1010

getHeight(cartographic) → Number|undefined

Get the height of the surface at a given cartographic.

Name	Type	Description
cartographic	Cartographic	The cartographic for which to find the height.

Returns:

The height of the cartographic or undefined if it could not be found.

Source: Scene/Globe.js, line 406

isDestroyed() → Boolean

Returns true if this object was destroyed; otherwise, false.

If this object was destroyed, it should not be used; calling any function other than isDestroyed will result in a DeveloperError exception.

Returns:

True if this object was destroyed; otherwise, false.

See:

• Globe#destroy

Source: Scene/Globe.js, line 989

pick(ray, scene, result) → Cartesian3|undefined

Find an intersection between a ray and the globe surface that was rendered. The ray must be given in world coordinates.

Name	Type	Description
ray	Ray	The ray to test for intersection.
scene	Scene	The scene.
result	Cartesian3	optional The object onto which to store the result.

Returns:

The intersection or undefined if none was found.

Example:

// find intersection of ray through a pixel and the globe
var ray = scene.camera.getPickRay(windowCoordinates);
var intersection = globe.pick(ray, scene);
