		<h1>[name]</h1>

		<p class="desc">
			A class containing useful utility functions for camera manipulation.
		</p>

		<h2>Import</h2>

		<p>
			[name] is an add-on, and must be imported explicitly.
			See [link:#manual/introduction/Installation Installation / Addons].
		</p>

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

		<h2>Methods</h2>

		<h3>[method:undefined frameCorners]( [param:PerspectiveCamera camera], [param:Vector3 bottomLeftCorner], [param:Vector3 bottomRightCorner], [param:Vector3 topLeftCorner], [param:boolean estimateViewFrustum] )</h3>
		<p>
		Set a PerspectiveCamera's projectionMatrix and quaternion to exactly frame the corners of an arbitrary rectangle using [link:https://web.archive.org/web/20191110002841/http://csc.lsu.edu/~kooima/articles/genperspective/index.html Kooima's Generalized Perspective Projection formulation].
		NOTE: This function ignores the standard parameters; do not call updateProjectionMatrix() after this! toJSON will also not capture the off-axis matrix generated by this function.
		</p>
