Default Value:
1.0
Example:
// Set back face translucency to 0.5.
globe.translucency.backFaceAlpha = 0.5;
globe.translucency.enabled = true;See:
backFaceAlphaByDistance : NearFarScalar
根据相机的距离,获取或设定地球后脸的近和远透明特性.
The translucency will interpolate between the
NearFarScalar#nearValue and
NearFarScalar#farValue while the camera distance falls within the lower and upper bounds
of the specified NearFarScalar#near and NearFarScalar#far.
在这些范围之外,透明性仍被限制在最接近的界限内。 如果未定义,
背面的AlphaByDistance将被禁用.
GlobeTranslucency#enabled must be set to true for this option to take effect.

Default Value:
undefined
Examples:
// Example 1.
// Set back face translucency to 0.5 when the
// camera is 1500 meters from the surface and 1.0
// as the camera distance approaches 8.0e6 meters.
globe.translucency.backFaceAlphaByDistance = new Cesium.NearFarScalar(1.5e2, 0.5, 8.0e6, 1.0);
globe.translucency.enabled = true;// Example 2.
// Disable back face translucency by distance
globe.translucency.backFaceAlphaByDistance = undefined;See:
如果是真的,地球会变成半透明表面.
The alpha is computed by blending
透明默认被禁用 .
The alpha is computed by blending
Globe#material, Globe#imageryLayers,
and Globe#baseColor, all of which may contain translucency, and then multiplying by
GlobeTranslucency#frontFaceAlpha and GlobeTranslucency#frontFaceAlphaByDistance for front faces and
GlobeTranslucency#backFaceAlpha and GlobeTranslucency#backFaceAlphaByDistance for back faces.
当相机是地下后脸和前脸互换时, NT 0 . 背面几何
被认为是正面面对.
透明默认被禁用 .
