KBE3D / KBCore / Cesium / Sun

类: Sun

Draws a sun billboard. <p>This is only supported in 3D and Columbus view.</p>

示例

scene.sun = new Cesium.Sun();

属性

show

show: boolean

Determines if the sun will be shown.

---

glowFactor

glowFactor: number

Gets or sets a number that controls how "bright" the Sun's lens flare appears to be. Zero shows just the Sun's disc without any flare. Use larger values for a more pronounced flare around the Sun.

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

sun = sun && sun.destroy();

构造函数
