		<h1>[name]</h1>

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

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


		<h2>Methods</h2>

		<h3>[method:Number interpolate]( p0, p1, p2, p3, t )</h3>
		<div>
		t -- interpolation weight. <br />
		p0, p1, p2, p4 -- the points defining the spline curve.<br /><br />

		Used internally by [page:SplineCurve SplineCurve] and [page:SplineCurve3 SplineCurve3].
		</div>

		<h3>[method:Number tangentQuadraticBezier]( t, p0, p1, p2 )</h3>
		<div>
		t -- the point at which to calculate the tangent. <br />
		p0, p1, p2 -- the three points defining the quadratic Bézier curve.<br /><br />

		Calculate the tangent at the point t on a quadratic Bézier curve given by the three points.<br /><br />

		Used internally by [page:QuadraticBezierCurve QuadraticBezierCurve].
		</div>

		<h3>[method:Number tangentCubicBezier]( t, p0, p1, p2, p3 )</h3>
		<div>
		t -- the point at which to calculate the tangent. <br />
		p0, p1, p2, p3 -- the points defining the cubic Bézier curve.<br /><br />

		Calculate the tangent at the point t on a cubic Bézier curve given by the four points.<br /><br />

		Used internally by [page:CubicBezierCurve CubicBezierCurve].
		</div>

		<h3>[method:Number tangentSpline]( t, p0, p1, p2, p3 )</h3>
		<div>
		t -- the point at which to calculate the tangent. <br />
		p0, p1, p2, p3 -- the points defining the spline curve.<br /><br />

		Calculate the tangent at the point t on a spline curve given by the four points.
		</div>
