<h1>半球光([name]</h1>
<p class="desc">
光源直接放置于场景之上,光照颜色从天空光线颜色渐变到地面光线颜色。
<br /><br />
半球光不能投射阴影。

<h2>构造器Constructor</h2>
<h3>[name]( [param:Integer skyColor], [param:Integer groundColor], [param:Float intensity] )</h3>
<p>
[page:Color skyColor] -(可选)一个表示颜色的 Color 的实例、字符串或数字默认为一个白色0xffffff的 [page:Color Color] 对象。<br />
[page:Color groundColor] -(可选)一个表示颜色的 Color 的实例、字符串或数字默认为一个白色0xffffff的 [page:Color Color] 对象。<br />
[page:Float intensity] -(可选)光照强度。默认值为 1。<br /><br />
创建一个半球光。
</p>
<h2>属性Properties</h2>
<p>
公共属性请查看基类 [page:Light Light]。
</p>
<h3>[property:Color color]</h3>
<p>
在构造时传递的天空发出光线的颜色。
默认值为白色0xffffff的 [page:Color] 对象。
</p>
<h3>[property:Color groundColor]</h3>
<p>
在构造时传递的地面发出光线的颜色。
默认值为白色0xffffff的 [page:Color] 对象。
</p>
<h3>[property:Boolean isHemisphereLight]</h3>
<p>
只读,用于检查对象的类型是否为 [name]。
</p>
<h3>[property:Vector3 position]</h3>
<p>
假如这个值设置为 [page:Object3D.DEFAULT_UP] (0, 1, 0),光线将会从上往下照射。
</p>
<h2>方法Methods</h2>
<p>公共方法请查看基类 [page:Light Light]。</p>
<h3>[method:this copy]( [param:HemisphereLight source] )</h3>
<p>
从 [page:Light source] 复制 [page:.color color]、[page:.intensity intensity] 和
[page:.groundColor groundColor] 的值到当前半球光对象中。
