|
|
<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*.

<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。
