SkyBox - CesiumJS API 文档

new Cesium.SkyBox(options)

环绕场景的天盒画星. 天框使用真赤道平均Equinox( TEME )轴来定义.

这只在3D中支持. 天盒在变形到2D或哥伦布视图时会淡出. 规模 the sky box must not exceed Scene#maximumCubeMapSize.

Name Type Description

options

object

下列属性的对象 :

Name	Type	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	`true`	optional Determines if this primitive will be shown.

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'
  }
});

See:

Members

show : boolean

确定是否显示天框.

Default Value: true

sources : object

获取或设定原始对象.

Methods

static Cesium.SkyBox.createEarthSkyBox() → SkyBox

为地球创建默认星图的天盒实例.

Returns:

地球默认天盒

Example:

viewer.scene.skyBox = Cesium.SkyBox.createEarthSkyBox();

destroy()

Destroys the WebGL resources held by this object. Destroying an object allows for deterministic 释放 WebGL 资源,而不是依赖垃圾收集器来摧毁此对象.

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.

Throws:

DeveloperError : This object was destroyed, i.e., destroy() was called.

Example:

skyBox = skyBox && skyBox.destroy();

See:

SkyBox#isDestroyed

isDestroyed() → boolean

如果此对象被销毁, 返回真实; 否则, 错误 .

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:

SkyBox#destroy

update()

Called when Viewer or CesiumWidget render the scene to 获得使这个原始化所需的绘图命令.

不要直接调用此函数。记录下来的只是列出场景拍摄时可能宣传的例外情况:

Throws:

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