		<p class="desc">
			Camera that uses [link:https://en.wikipedia.org/wiki/Orthographic_projection orthographic projection].<br /><br />

			In this projection mode, an object's size in the rendered image stays constant
			regardless of its distance from the camera.<br /><br />

			This can be useful for rendering 2D scenes and UI elements, amongst other things.

		<h2>Constructor</h2>


		<h3>[name]( [param:Number left], [param:Number right], [param:Number top], [param:Number bottom], [param:Number near], [param:Number far] )</h3>
		<p>
		left — Camera frustum left plane.<br />
		right — Camera frustum right plane.<br />
		top — Camera frustum top plane.<br />
		bottom — Camera frustum bottom plane.<br />
		near — Camera frustum near plane.<br />
		far — Camera frustum far plane.<br /><br />

		Together these define the camera's [link:https://en.wikipedia.org/wiki/Viewing_frustum viewing frustum].
		</p>


		<h2>Properties</h2>
		<p>
			See the base [page:Camera] class for common properties.<br>
 			Note that after making changes to most of these properties you will have to call
 			[page:OrthographicCamera.updateProjectionMatrix .updateProjectionMatrix] for the changes to take effect.
		</p>

		<h3>[property:Float bottom]</h3>
		<p>Camera frustum bottom plane.</p>

		<h3>[property:Float far]</h3>
		<p>
		Camera frustum far plane. Default is *2000*.<br /><br />

		The valid range is between the current value of the [page:.near near] plane and infinity.
		</p>

		<h3>[property:Boolean isOrthographicCamera]</h3>
		<p>
			Used to test whether this or derived classes are OrthographicCameras. Default is *true*.<br /><br />

			This should not be changed as it is used internally by the renderer for optimisation.
		</p>

		<h3>[property:Float left]</h3>
		<p>Camera frustum left plane.</p>

		<h3>[property:Float near]</h3>
		<p>
			Camera frustum near plane. Default is *0.1*.<br /><br />

			The valid range is between 0 and the current value of the [page:.far far] plane.
			Note that, unlike for the [page:PerspectiveCamera], *0* is a valid value for an
			OrthographicCamera's near plane.
		</p>

		<h3>[property:Float right]</h3>
		<p>Camera frustum right plane.</p>

		<h3>[property:Float top]</h3>
		<p>Camera frustum top plane.</p>

		<h3>[property:Object view]</h3>
		<p>Set by [page:OrthographicCamera.setViewOffset setViewOffset]. Default is *null*.</p>

		<h3>[property:number zoom]</h3>
		<p>Gets or sets the zoom factor of the camera. Default is *1*.</p>

		<h2>Methods</h2>
		<p>See the base [page:Camera] class for common methods.</p>

		<h3>[method:null setViewOffset]( [param:Float fullWidth], [param:Float fullHeight], [param:Float x], [param:Float y], [param:Float width], [param:Float height] )</h3>
		<p>
		fullWidth — full width of multiview setup<br />
		fullHeight — full height of multiview setup<br />
		x — horizontal offset of subcamera<br />
		y — vertical offset of subcamera<br />
		width — width of subcamera<br />
		height — height of subcamera<br /><br />

			Sets an offset in a larger [link:https://en.wikipedia.org/wiki/Viewing_frustum viewing frustum].
			This is useful for multi-window or multi-monitor/multi-machine setups.
			For an example on how to use it see [page:PerspectiveCamera.setViewOffset PerspectiveCamera].
		</p>

		<h3>[method:null clearViewOffset]()</h3>
		<p>
		Removes any offset set by the .setViewOffset method.
		</p>

		<h3>[method:null updateProjectionMatrix]()</h3>
		<p>
		Updates the camera projection matrix. Must be called after any change of parameters.
		</p>

		<h3>[method:JSON toJSON]()</h3>
		<p>
		Return the camera's data in JSON format.
		</p>
