<h2>构造器</h2>
<h3>[name]([param:Array shapes], [param:Integer curveSegments])</h3>
<p>
shapes — 一个单独的[page:Shape shape]，或者一个包含形状的[page:Array]。<br />
curveSegments - [page:Integer] - 每一个形状的分段数，默认值为12。
</p>
<h2>属性</h2>
<p>共有属性请参见其基类[page:Geometry]。</p>
<h3>[property:Object parameters]</h3>
<p>
一个包含着构造函数中每个参数的对象。在对象实例化之后，对该属性的任何修改都不会改变这个几何体。
</p>
<h2>方法(Methods)</h2>
<p>共有方法请参见其基类[page:Geometry]。</p>
