- <h1>[name]</h1>
- <p class="desc">
- 用于模拟相机视锥体的辅助对象.它使用 [page:LineSegments] 来模拟相机视锥体.<br /><br />
- [name] must be a child of the scene.
- </p>
- <h2>代码示例</h2>
- <code>
- const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );
- const helper = new THREE.CameraHelper( camera );
- scene.add( helper );
- </code>
- <h2>例子</h2>
- <p>
- [example:webgl_camera WebGL / camera]<br/>
- [example:webgl_geometry_extrude_splines WebGL / extrude / splines]
- </p>
- <h2>构造函数</h2>
- <h3>[name]( [param:Camera camera] )</h3>
- <p>
- [page:Camera camera] -- 被模拟的相机.<br /><br />
- 为指定相机创建一个新的相机辅助对象 [Name] .
- </p>
- <h2>属性</h2>
- <p>请到基类 [page:LineSegments] 页面查看公共属性.</p>
- <h3>[property:Camera camera]</h3>
- <p>被模拟的相机.</p>
- <h3>[property:Object pointMap]</h3>
- <p>包含用于模拟相机的点.</p>
- <h3>[property:Object matrix]</h3>
- <p>请参考相机的世界矩阵 [page:Object3D.matrixWorld camera.matrixWorld].</p>
- <h3>[property:Object matrixAutoUpdate]</h3>
- <p>
- 请查看 [page:Object3D.matrixAutoUpdate]. 这里设置为 *false* 表示辅助对象
- 使用相机的 [page:Object3D.matrixWorld matrixWorld].
- </p>
- <h2>方法</h2>
- <p>请到基类 [page:LineSegments] 页面查看公共方法.</p>
- <h3>[method:undefined dispose]()</h3>
- <p>
- 用于辅助对象销毁内部创建的 [page:Line.material material] 和 [page:Line.geometry geometry] 。
- </p>
- <h3>[method:this setColors]( [param:Color frustum], [param:Color cone], [param:Color up], [param:Color target], [param:Color cross] )</h3>
- <p>
- 定义辅助对象的颜色。
- </p>
- <h3>[method:undefined update]()</h3>
- <p>基于相机的投影矩阵更新辅助对象.</p>
