		<h1>[name]</h1>

		<div class="desc">
		An abstract base class further extending [page:Curve]. A CurvePath is simply an array of connected curves,
		but retains the api of a curve.
		</div>


		<h2>Constructor</h2>


		<h3>[name]()</h3>
		<div>
		The constructor take no parameters.
		</div>


		<h2>Properties</h2>


		<h3>[property:array curves]</h3>
		<div>
		The array of [page:Curve]s
		</div>

		<h3>[property:array bends]</h3>
		<div>
		An array of [page:Curve]s used to transform and bend the curve using [page:CurvePath.getWrapPoints].
		</div>

		<h3>[property:boolean autoClose]</h3>
		<div>
		Whether or not to automatically close the path.
		</div>

		<h2>Methods</h2>


		<h3>[method:Array getWrapPoints]( [page:Array vertices], [page:Curve curve] )</h3>
		<div>
		vertices -- An array of [page:Vector2]s to modify<br />
		curve -- An array of 2d [page:Curve]s
		</div>
		<div>
		Modifies the array of vertices by warping it by the curve. The curve parameter also accepts objects with similar
		interfaces such as [page:CurvePath], [page:Path], [page:SplineCurve], etc. Returns the original vertices after
		modification.
		</div>

		<h3>[method:null addWrapPath]( [page:Curve curve] )</h3>
		<div>
		curve -- A [page:Curve] or object with a similar interface.
		</div>
		<div>
		Pushes a curve onto the bends array.
		</div>

		<h3>[method:Geometry createGeometry]( [page:Vector3 points] )</h3>
		<div>
		points -- An array of [page:Vector3]s
		</div>
		<div>
		Creates a geometry from points
		</div>

		<h3>[method:Geometry createPointsGeometry]( [page:Integer divisions] )</h3>
		<div>
		divisions -- How many segments to create with [page:Vector3]s. Defaults to 12.
		</div>
		<div>
		Creates a [page:Geometry] object comprised of [page:Vector3]s
		</div>

		<h3>[method:Geometry createSpacedPointsGeometry]( [page:Integer divisions] )</h3>
		<div>
		divisions -- How many segments to create with [page:Vector3]s. Defaults to 12.
		</div>
		<div>
		Creates a [page:Geometry] object comprised of [page:Vector3]s that are equidistant.
		</div>


		<h3>[method:null add]( [page:Curve curve] )</h3>
		<div>
		curve -- The [page:Curve curve] to add
		</div>
		<div>
		Pushes a curve onto the curves array.
		</div>

		<h3>[method:null closePath]()</h3>
		<div>
		Adds a curve to close the path.
		</div>

		<h3>[method:Object getBoundingBox]()</h3>
		<div>
		Returns an object with the keys minX, minY, maxX, maxY, (if 3d: maxZ, minZ)
		</div>

		<h3>[method:Float getCurveLengths]()</h3>
		<div>
		Adds together the length of the curves
		</div>

		<h3>[method:Array getTransformedPoints]( [page:Integer segments], [page:Array bends] )</h3>
		<div>
		segments -- The number of segments to create using the getPoints()<br />
		bends -- (optional) An array of [page:Curve]s used to transform the points. Defaults to this.bends if blank.
		</div>
		<div>
		Uses this CurvePath to generate a series of points transformed by the curves in the bends array. Returns an
		array of [page:Vector2]s.
		</div>

		<h3>[method:Array getTransformedSpacedPoints]( [page:Integer segments], [page:Array bends] )</h3>
		<div>
		segments -- The number of segments to create using the getPoints()<br />
		bends -- (optional) Defaults to this.bends if blank. An array of [page:Curve]s used to transform the points.
		</div>
		<div>
		Uses this CurvePath to generate a series equidistant points that are then transformed by the curves in the bends.
	    Returns an array of [page:Vector2]s.
		</div>
