<p class="desc">
|

|
|
多面体在三维空间中具有一些平面的立体图形。这个类将一个顶点数组投射到一个球面上，之后将它们细分为所需的细节级别。
|
||
|
|
这个类由[page:DodecahedronGeometry]、[page:IcosahedronGeometry]、[page:OctahedronGeometry]和[page:TetrahedronGeometry]
|
||
|
|
所使用，以生成它们各自的几何结构。

|
|
-1,-1, 1, 1,-1, 1, 1, 1, 1, -1, 1, 1,

<h2>构造器</h2>
|
||
|
|
|
||
|
|
|
||
|
|
<h3>[name]([param:Array vertices], [param:Array indices], [param:Float radius], [param:Integer detail])</h3>
|
||
|
|
<p>
|
||
|
|
vertices — 一个顶点[page:Array]（数组）：[1,1,1, -1,-1,-1, ... ]。 <br />
|
||
|
|
indices — 一个构成面的索引[page:Array]（数组）， [0,1,2, 2,3,0, ... ]。<br />
|
||
|
|
radius — [page:Float] - 最终形状的半径。<br />
|
||
|
|
detail — [page:Integer] - 将对这个几何体细分多少个级别。细节越多，形状就越平滑。
|
||
|
|

<h2>属性</h2>

<p>共有属性请参见其基类[page:BufferGeometry]。</p>
|

|
|
|
||
|
|
<h3>[property:Object parameters]</h3>
|
||
|
|
<p>
|
||
|
|
一个包含着构造函数中每个参数的对象。在对象实例化之后，对该属性的任何修改都不会改变这个几何体。
