|
|
A class containing utility functions for shapes.<br /><br />
|

Note that these are all linear functions so it is necessary to calculate separately for
|
||
|
|
x, y (and z, w if present) components of a vector.

<h2>Methods</h2>
|
||
|
|
|
||
|
|
<h3>[method:Number area]( contour )</h3>
|
||
|
|
<p>
|
||
|
|
contour -- 2D polygon. An array of THREE.Vector2()<br /><br />
|
||
|
|
|
||
|
|
Calculate area of a ( 2D ) contour polygon.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:Boolean isClockWise]( pts )</h3>
|
||
|
|
<p>
|
||
|
|
pts -- points defining a 2D polygon<br /><br />
|
||
|
|
|
||
|
|
Note that this is a linear function so it is necessary to calculate separately for
|
||
|
|
x, y components of a polygon.<br /><br />
|
||
|
|
|
||
|
|
Used internally by [page:Path Path],
|
||
|
|
[page:ExtrudeGeometry ExtrudeGeometry] and [page:ShapeGeometry ShapeGeometry].
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<h3>[method:Array triangulateShape]( contour, holes )</h3>
|
||
|
|
<p>
|
||
|
|
contour -- 2D polygon. An array of [page:Vector2].<br />
|
||
|
|
holes -- An array that holds arrays of [page:Vector2]s. Each array represents a single hole definition.<br /><br />
|
||
|
|
|
||
|
|
Used internally by [page:ExtrudeGeometry ExtrudeGeometry] and [page:ShapeGeometry ShapeGeometry] to calculate faces in shapes with holes.
