KBE3D / KBCore / Cesium / SkyAtmosphere

类: SkyAtmosphere

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

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

示例

scene.skyAtmosphere = new Cesium.SkyAtmosphere();

参数

The ellipsoid that the atmosphere is drawn around.

属性

show

show: boolean

Determines if the atmosphere is shown.

---

perFragmentAtmosphere

perFragmentAtmosphere: boolean

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

---

atmosphereLightIntensity

atmosphereLightIntensity: number

The intensity of the light that is used for computing the sky atmosphere color.

---

atmosphereRayleighCoefficient

atmosphereRayleighCoefficient: Cartesian3

The Rayleigh scattering coefficient used in the atmospheric scattering equations for the sky atmosphere.

---

atmosphereMieCoefficient

atmosphereMieCoefficient: Cartesian3

The Mie scattering coefficient used in the atmospheric scattering equations for the sky atmosphere.

---

atmosphereRayleighScaleHeight

atmosphereRayleighScaleHeight: number

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

---

atmosphereMieScaleHeight

atmosphereMieScaleHeight: number

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

---

atmosphereMieAnisotropy

atmosphereMieAnisotropy: number

The anisotropy of the medium to consider for Mie scattering. <p> Valid values are between -1.0 and 1.0. </p>

---

hueShift

hueShift: number

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.

---

saturationShift

saturationShift: number

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

---

brightnessShift

brightnessShift: number

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.

---

ellipsoid

readonly ellipsoid: Ellipsoid

Gets the ellipsoid the atmosphere is drawn around.

方法

isDestroyed()

isDestroyed(): boolean

Returns true if this object was destroyed; otherwise, false. <br /><br /> If this object was destroyed, it should not be used; calling any function other than <code>isDestroyed</code> will result in a DeveloperError exception.

返回

boolean

true if this object was destroyed; otherwise, false.

---

destroy()

destroy(): void

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. <br /><br /> Once an object is destroyed, it should not be used; calling any function other than <code>isDestroyed</code> will result in a DeveloperError exception. Therefore, assign the return value (<code>undefined</code>) to the object as done in the example.

返回

void

示例

skyAtmosphere = skyAtmosphere && skyAtmosphere.destroy();
