  24. <h2>代码示例</h2>
  25. <code>
  26. var geometry = new THREE.CircleBufferGeometry( 5, 32 );
  27. var material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
  28. var circle = new THREE.Mesh( geometry, material );
  29. scene.add( circle );

  31. <h2>构造器</h2>
  32. <h3>[name]([param:Float radius], [param:Integer segments], [param:Float thetaStart], [param:Float thetaLength])</h3>
  33. <p>
  34. radius — 圆形的半径,默认值为1<br />
  35. segments — 分段(三角面)的数量,最小值为3,默认值为8。<br />
  36. thetaStart — 第一个分段的起始角度,默认为0。(three o'clock position)<br />
  37. thetaLength — 圆形扇区的中心角,通常被称为“θ”(西塔)。默认值是2*Pi,这使其成为一个完整的圆。

  39. <h2>属性</h2>
  40. <p>共有属性请参见其基类[page:BufferGeometry]。</p>
  41. <h3>[property:Object parameters]</h3>
  42. <p>
  43. 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。
