<h1>圆柱坐标([name])</h1>
<p class="desc">
一个点的[link:https://en.wikipedia.org/wiki/Cylindrical_coordinate_system cylindrical coordinates](圆柱坐标)。
</p>
<h2>构造器(Constructor)</h2>
<h3>[name]( [param:Float radius], [param:Float theta], [param:Float y] )</h3>
<p>
[page:Float radius] - 从原点到x-z平面上一点的距离
默认值为 *1.0*.<br />
[page:Float theta] - 在x-z平面内的逆时针角度,以z轴正方向的计算弧度。默认值为0。<br />
[page:Float y] - x-z平面以上的高度 默认值为 *0*.
</p>
<h2>属性(Properties)</h2>
<h3>[property:Float radius]</h3>
<h3>[property:Float theta]</h3>
<h3>[property:Float y]</h3>
<h2>Methods</h2>
<h3>[method:Cylindrical clone]()</h3>
<p>
返回一个与当前拥有相同 [page:.radius radius], [page:.theta theta] 和 [page:.y y] 属性的圆柱坐标。
</p>
<h3>[method:this copy]( [param:Cylindrical other] )</h3>
<p>
将传入的圆柱坐标对象的 [page:.radius radius], [page:.theta theta] 和 [page:.y y] 属性赋给当前对象。
</p>
<h3>[method:this set]( [param:Float radius], [param:Float theta], [param:Float y] )</h3>
<p>设置该对象的 [page:.radius radius], [page:.theta theta]
和 [page:.y y] 属性。</p>
<h3>[method:this setFromVector3]( [param:Vector3 vec3] )</h3>
<p>
从 [page:Vector3 Vector3] 中取x,y,z,并调用setFromCartesianCoords来设置圆柱坐标的
[page:.radius radius]、[page:.theta theta] 和 [page:.y y] 的属性值。
</p>
<h3>[method:this setFromCartesianCoords]( [param:Float x], [param:Float y], [param:Float z] )</h3>
<p>
使用笛卡尔坐标来设置该圆柱坐标中 [page:.radius radius], [page:.theta theta]
以及 [page:.y y] 的属性值。
