		包含用于相机操作的有用实用函数的类。
	</p>

	<h2>导入</h2>

	<p>
		[name] 是一个附加组件，必须显式导入。请参阅 [link:#manual/introduction/Installation Installation / Addons].
	</p>

	<code>
			import * as CameraUtils from 'three/addons/utils/CameraUtils.js';
		</code>

	<h2>方法</h2>

	<h3>[method:undefined frameCorners]( [param:PerspectiveCamera camera], [param:Vector3 bottomLeftCorner],
		[param:Vector3 bottomRightCorner], [param:Vector3 topLeftCorner], [param:boolean estimateViewFrustum] )</h3>
	<p>
		使用 [link:https://web.archive.org/web/20191110002841/http://csc.lsu.edu/~kooima/articles/genperspective/index.html
		Kooima 广义透视投影公式].
		注意：此功能忽略标准参数；在此之后不要调用 updateProjectionMatrix() ！ toJSON也不会捕获此函数生成的离轴矩阵。
