<h1>边缘几何体（[name]）</h1>

<p class="desc">这可以作为一个辅助对象来查看[page:BufferGeometry geometry]的边缘。</p>

<h2>代码示例</h2>
|
|
<code>
|
|
const geometry = new THREE.BoxGeometry( 100, 100, 100 );
|
|
const edges = new THREE.EdgesGeometry( geometry );
|
|
const line = new THREE.LineSegments( edges, new THREE.LineBasicMaterial( { color: 0xffffff } ) );
|
|
scene.add( line );
|
|
</code>

<h2>构造器</h2>
|
|
|
|
<h3>[name]( [param:BufferGeometry geometry], [param:Integer thresholdAngle] )</h3>
|
|
<p>
|
|
geometry — 任何一个几何体对象。<br />
|
|
thresholdAngle — 仅当相邻面的法线之间的角度（单位为角度）超过这个值时，才会渲染边缘。默认值为1。

<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。
