		<div class="desc">Abstract base class for cameras. This class should always be inherited when you build a new camera.</div>


		<h2>Constructor</h2>


		<h3>[name]()</h3>
		<div>
			This constructor sets the following properties to the correct type: matrixWorldInverse and projectionMatrix.

		</div>


		<h2>Properties</h2>

		<h3>[property:Matrix4 matrixWorldInverse]</h3>
		<div>This is the inverse of matrixWorld. MatrixWorld contains the Matrix which has the world transform of the Camera.</div>

		<h3>[property:Matrix4 projectionMatrix]</h3>
		<div>This is the matrix which contains the projection.</div>


		<h2>Methods</h2>

		<h3>[method:Vector3 getWorldDirection]([page:Vector3 vector])</h3>
		<div>
		vector — (optional)<br />
		<br />
		It returns a vector representing the direction in which the camera is looking, in world space.
		</div>


		<h3>[method:null lookAt]( [page:Vector3 vector] )</h3>
		<div>
		vector — point to look at<br />
		<br />
		This makes the camera look at the vector position in the global space as long as the parent of this camera is the scene or at position (0,0,0).
		</div>

		<h3>[method:Camera clone]( [page:Camera camera] )</h3>
		<div>
		camera — camera to clone<br />
		<br />
