<h1>[name]</h1>
<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.
</p>
<h2>Example</h2>

<code>var camera = new THREE.OrthographicCamera( width / - 2, width / 2, height / 2, height / - 2, 1, 1000 );

<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:Object toJSON]([param:object meta])</h3>
<p>
meta -- object containing metadata such as textures or images in objects' descendants.<br />
Convert the camera to three.js [link:https://github.com/mrdoob/three.js/wiki/JSON-Object-Scene-format-4 JSON Object/Scene format].
