- <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]。Default is a single triangle shape.<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:BufferGeometry]。</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>
