KBE3D / KBCore / Cesium / Atmosphere

类: Atmosphere

Common atmosphere settings used by 3D Tiles and models for rendering sky atmosphere, ground atmosphere, and fog.

<p> This class is not to be confused with SkyAtmosphere, which is responsible for rendering the sky. </p> <p> While the atmosphere settings affect the color of fog, see Fog to control how fog is rendered. </p>

Examples

// Turn on dynamic atmosphere lighting using the sun direction
scene.atmosphere.dynamicLighting = Cesium.DynamicAtmosphereLightingType.SUNLIGHT;

// Turn on dynamic lighting using whatever light source is in the scene
scene.light = new Cesium.DirectionalLight({
  direction: new Cesium.Cartesian3(1, 0, 0)
});
scene.atmosphere.dynamicLighting = Cesium.DynamicAtmosphereLightingType.SCENE_LIGHT;

// Adjust the color of the atmosphere effects.
scene.atmosphere.hueShift = 0.4; // Cycle 40% around the color wheel
scene.atmosphere.brightnessShift = 0.25; // Increase the brightness
scene.atmosphere.saturationShift = -0.1; // Desaturate the colors

属性

lightIntensity

lightIntensity: number

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

---

rayleighCoefficient

rayleighCoefficient: Cartesian3

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

---

mieCoefficient

mieCoefficient: Cartesian3

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

---

rayleighScaleHeight

rayleighScaleHeight: number

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

---

mieScaleHeight

mieScaleHeight: number

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

---

mieAnisotropy

mieAnisotropy: 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.

---

dynamicLighting

dynamicLighting: DynamicAtmosphereLightingType

When not DynamicAtmosphereLightingType.NONE, the selected light source will be used for dynamically lighting all atmosphere-related rendering effects.
