- <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>例子</h2>
- <p>
- [example:webgl_helpers helpers]
- </p>
- <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。
- </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。
