<div class="desc">Euler Angles. <br/><br/>
Euler angles describe a rotation transformation by rotating an object on its various axes in specified amounts per axis, and a specified axis order.
(More information on <a href='http://en.wikipedia.org/wiki/Euler_angles' target='blank'>Wikipedia</a>)</div>
<h2>Example</h2>
<code>var a = new THREE.Euler( 0, 1, 1.57, 'XYZ' );
var b = new THREE.Vector3( 1, 0, 1 );
b.applyEuler(a);
</code>
<h2>Constructor</h2>
<h3>[name]( [page:Float x], [page:Float y], [page:Float z], [page:String order] )</h3>
<div>
x -- [page:Float] the angle of the x axis in radians<br />
y -- [page:Float] the angle of the y axis in radians<br />
z -- [page:Float] the angle of the z axis in radians<br />
order -- [page:String] A string representing the order that the rotations are applied, defaults to 'XYZ' (must be upper case).
</div>
<div>
A euler angle for transforming
</div>
<h2>Properties</h2>
<h3>[property:Float x]</h3>
<h3>[property:Float y]</h3>

<div>
x -- [page:Float] Angle in x axis in radians<br />
y -- [page:Float] Angle in y axis in radians<br />
z -- [page:Float] Angle in z axis in radians<br />
order -- [page:string] Order of axes, defaults to 'XYZ' (must be upper case)
</div>
<div>
Sets the angles of this euler transform.
</div>
<h3>[method:Euler copy]( [page:Euler euler] ) [page:Euler this]</h3>
<div>
Copies value of *euler* to this euler.
</div>
<h3>[method:Euler setFromRotationMatrix]( [page:Matrix4 m], [page:String order] ) [page:Euler this]</h3>
<div>
m -- [page:Matrix4] assumes upper 3x3 of matrix is a pure rotation matrix (i.e. unscaled)<br />
order -- [page:string] Order of axes, defaults to 'XYZ' (must be upper case)
</div>
<div>
Sets the angles of this euler transform from a pure rotation matrix based on the orientation specified by order.
</div>
<h3>[method:Euler setFromQuaternion]( [page:Quaternion q], [page:String order] ) [page:Euler this]</h3>
<div>
q -- [page:Quaternion] quaternion must be normalized<br />
order -- [page:string] Order of axes, defaults to 'XYZ' (must be upper case)
</div>
<div>
Sets the angles of this euler transform from a normalized quaternion based on the orientation specified by order.
</div>
<h3>[method:Euler reorder]( [page:String newOrder] ) [page:Euler this]</h3>
<div>
Resets the euler angle with a new order by creating a quaternion from this euler angle and then setting this euler angle with the quaternion and the new order. <br />
WARNING: this discards revolution information.
</div>
<h3>[method:Euler setFromVector3]([page:Vector3 vector], [page:String order]) [page:Euler this]</h3>
<div>
vector -- [page:Vector3].
order -- [page:string] Order of axes, defaults to 'XYZ' (must be upper case)
