 		<h3>[property:Float bottom]</h3>
-		<p>Camera frustum bottom plane.</p>
+		<p>摄像机视锥体下侧面。</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.
+			摄像机视锥体远端面，其默认值为*2000*。<br /><br />
+			其值的有效范围介于[page:.near near]（摄像机视锥体近端面）和无穷大之间。

 		<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.
+			用于测试这个类或者派生类是否为OrthographicCameras，默认为*true*。<br /><br />
+			你不应当对这个属性进行改变,因为它在内部由渲染器使用，以用于优化。

+			请注意，和[page:PerspectiveCamera]不同，*0*对于OrthographicCamera的近端面来说是一个有效值。
 
-			The valid range is between 0 and the current value of the [page:.far far] plane.

 		<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].
+		fullWidth — 多视图的全宽设置<br />
+		fullHeight — 多视图的全高设置<br />
+		x — 副摄像机的水平偏移<br />
+		y — 副摄像机的垂直偏移<br />
+		width — 副摄像机的宽度<br />
+		height — 副摄像机的高度<br /><br />
+
+			在较大的[link:https://en.wikipedia.org/wiki/Viewing_frustum viewing frustum]（视锥体）中设置偏移量，对于多窗口或者多显示器的设置是很有用的。
+			对于如何使用它，请查看[page:PerspectiveCamera.setViewOffset PerspectiveCamera]中的示例。

 		<h3>[method:null clearViewOffset]()</h3>
 		<p>
-		Removes any offset set by the .setViewOffset method.
+			清除任何由.setViewOffset设置的偏移量。
 		</p>
 
 		<h3>[method:null updateProjectionMatrix]()</h3>
 		<p>
-		Updates the camera projection matrix. Must be called after any change of parameters.
+			更新摄像机投影矩阵。在任何参数被改变以后必须被调用。
 		</p>
 
 		<h3>[method:JSON toJSON]()</h3>
 		<p>
-		Return the camera's data in JSON format.
+		使用JSON格式来返回摄像机数据。
