new Cesium.SkyAtmosphere(ellipsoid)
engine/Source/Scene/SkyAtmosphere.js 43

An atmosphere drawn around the limb of the provided ellipsoid. Based on Display of The Earth Taking Into Account Atmospheric Scattering.

This is only supported in 3D. Atmosphere is faded out when morphing to 2D or Columbus view.

参数名称 类型 默认值 描述信息
ellipsoid Ellipsoid Ellipsoid.WGS84 可选 The ellipsoid that the atmosphere is drawn around.
使用示例:
scene.skyAtmosphere = new Cesium.SkyAtmosphere();

成员(属性)

atmosphereLightIntensity : number
engine/Source/Scene/SkyAtmosphere.js 89

The intensity of the light that is used for computing the sky atmosphere color.
默认值: 50.0

atmosphereMieAnisotropy : number
engine/Source/Scene/SkyAtmosphere.js 131

The anisotropy of the medium to consider for Mie scattering.

Valid values are between -1.0 and 1.0.

默认值: 0.9

atmosphereMieCoefficient : Cartesian3
engine/Source/Scene/SkyAtmosphere.js 105

The Mie scattering coefficient used in the atmospheric scattering equations for the sky atmosphere.
默认值: Cartesian3(21e-6, 21e-6, 21e-6)

atmosphereMieScaleHeight : number
engine/Source/Scene/SkyAtmosphere.js 121

The Mie scale height used in the atmospheric scattering equations for the sky atmosphere, in meters.
默认值: 3200.0

atmosphereRayleighCoefficient : Cartesian3
engine/Source/Scene/SkyAtmosphere.js 97

The Rayleigh scattering coefficient used in the atmospheric scattering equations for the sky atmosphere.
默认值: Cartesian3(5.5e-6, 13.0e-6, 28.4e-6)

atmosphereRayleighScaleHeight : number
engine/Source/Scene/SkyAtmosphere.js 113

The Rayleigh scale height used in the atmospheric scattering equations for the sky atmosphere, in meters.
默认值: 10000.0

brightnessShift : number
engine/Source/Scene/SkyAtmosphere.js 155

The brightness shift to apply to the atmosphere. Defaults to 0.0 (no shift). A brightness shift of -1.0 is complete darkness, which will let space show through.
默认值: 0.0

readonly ellipsoid : Ellipsoid
engine/Source/Scene/SkyAtmosphere.js 212

Gets the ellipsoid the atmosphere is drawn around.

hueShift : number
engine/Source/Scene/SkyAtmosphere.js 139

The hue shift to apply to the atmosphere. Defaults to 0.0 (no shift). A hue shift of 1.0 indicates a complete rotation of the hues available.
默认值: 0.0

perFragmentAtmosphere : boolean
engine/Source/Scene/SkyAtmosphere.js 61

Compute atmosphere per-fragment instead of per-vertex. This produces better looking atmosphere with a slight performance penalty.
默认值: false

saturationShift : number
engine/Source/Scene/SkyAtmosphere.js 147

The saturation shift to apply to the atmosphere. Defaults to 0.0 (no shift). A saturation shift of -1.0 is monochrome.
默认值: 0.0

show : boolean
engine/Source/Scene/SkyAtmosphere.js 52

Determines if the atmosphere is shown.
默认值: true

方法

destroy()
engine/Source/Scene/SkyAtmosphere.js 394

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.
Throws:
  • DeveloperError : This object was destroyed, i.e., destroy() was called.
使用示例:
skyAtmosphere = skyAtmosphere && skyAtmosphere.destroy();
参考:

isDestroyed() → boolean
engine/Source/Scene/SkyAtmosphere.js 374

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.
返回值:
true if this object was destroyed; otherwise, false.
