Class: SkyBox

SkyBox

new SkyBox(options)

A sky box around the scene to draw stars. The sky box is defined using the True Equator Mean Equinox (TEME) axes.

This is only supported in 3D. The sky box is faded out when morphing to 2D or Columbus view. The size of the sky box must not exceed Scene#maximumCubeMapSize.

Parameters:
Name Type Description
options Object Object with the following properties:
Properties
Name Type Attributes Default Description
sources Object <optional>
 The source URL or Image object for each of the six cube map faces. See the example below.
show Boolean <optional>
 true Determines if this primitive will be shown.
Source:

Example
scene.skyBox = new Cesium.SkyBox({
  sources : {
    positiveX : 'skybox_px.png',
    negativeX : 'skybox_nx.png',
    positiveY : 'skybox_py.png',
    negativeY : 'skybox_ny.png',
    positiveZ : 'skybox_pz.png',
    negativeZ : 'skybox_nz.png'
  }
});

Members

show :Boolean

Determines if the sky box will be shown.
Type:
  • Boolean
Default Value:
  • true
Source:

sources :Object

The sources used to create the cube map faces: an object with positiveX, negativeX, positiveY, negativeY, positiveZ, and negativeZ properties. These can be either URLs or Image objects.
Type:
  • Object
Default Value:
  • undefined

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.
Source:
See:
Throws:
This object was destroyed, i.e., destroy() was called.
Type
DeveloperError
Returns:
Type
undefined
Example
skyBox = skyBox && skyBox.destroy();

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.
Type
Boolean

update()

Called when Viewer or CesiumWidget render the scene to get the draw commands needed to render this primitive.

Do not call this function directly. This is documented just to list the exceptions that may be propagated when the scene is rendered:

Source:
Throws:
  • this.sources is required and must have positiveX, negativeX, positiveY, negativeY, positiveZ, and negativeZ properties.
    Type
    DeveloperError
  • this.sources properties must all be the same type.
    Type
    DeveloperError
