		<h1>[name]</h1>

		<div class="desc">
		A class containing utility functions for shapes.<br /><br />

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


		<h2>Methods</h2>

		<h3>[method:Number area]( contour )</h3>
		<div>
		contour -- 2D polygon.<br /><br />

		Calculate area of a ( 2D ) contour polygon.<br /><br />

		</div>

		<h3>[method:Boolean isClockwise]( pts )</h3>
		<div>
		pts -- points defining a 2D polygon<br /><br />

		Note that this is a linear function so it is neccessary to calculate separately for
		x, y  components of a polygon.<br /><br />

		Used internally by [page:Path Path],
		[page:ExtrudeGeometry ExtrudeGeometry] and [page:ShapeBufferGeometry ShapeBufferGeometry].
		</div>

		<h3>[method:null triangulate]( contour, indices )</h3>
		<div>
		vertices -- flat array of vertices like [ x0,y0, x1,y1, x2,y2, ... ].<br />
		holeIndices -- array of hole indices.<br /><br />

		Performs a polygon triangulation based on earcut. The implementation is a port of [link:https://github.com/mapbox/earcut mapbox/earcut].
		</div>

		<h3>[method:null triangulateShape]( contour, holes )</h3>
		<div>
		contour -- 2D polygon.<br />
		holes -- array of holes<br /><br />

		Used by [page:ExtrudeGeometry ExtrudeGeometry] and [page:ShapeBufferGeometry ShapeBufferGeometry] to calculate faces in shapes with holes.
		</div>
