|
|
请注意，这些都是线性函数，因此有必要分别计算向量的x，y（和z，w，如果存在的话）分量。

<h2>方法</h2>
|
||
|
|
|
||
|
|
<h3>[method:Number area]( contour )</h3>
|
||
|
|
<p>
|
||
|
|
contour -- 2D多边形，一个THREE.Vector2()数组。<br /><br />
|
||
|
|
|
||
|
|
计算（2D）轮廓多边形的面积。
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:Boolean isClockWise]( pts )</h3>
|
||
|
|
<p>
|
||
|
|
pts -- 定义2D多边形的点<br /><br />
|
||
|
|
|
||
|
|
请注意，这是一个线性函数，因此需要分别计算多边形的x，y分量。<br /><br />
|
||
|
|
|
||
|
|
由[page:Path Path]，[page:ExtrudeGeometry ExtrudeGeometry]和[page:ShapeGeometry ShapeGeometry]内部使用。
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:Array triangulateShape]( contour, holes )</h3>
|
||
|
|
<p>
|
||
|
|
contour -- 2D多边形。<br />
|
||
|
|
holes -- 孔洞数组<br /><br />
|
||
|
|
|
||
|
|
由[page:ExtrudeGeometry ExtrudeGeometry]和[page:ShapeGeometry ShapeGeometry]内部使用以计算带孔的形状中的面。
