		<h1>[name]</h1>

		<div class="desc">A geometric line segment represented by a start and end point.</div>


		<h2>Constructor</h2>


		<h3>[name]( [page:Vector3 start], [page:Vector3 end] )</h3>
		<div>
		start -- [page:Vector3] Start of the line segment<br />
		end -- [page:Vector3] End of the line segment
		</div>
		<div>
		The start and end vectors default to origin vectors if none are set.
		</div>


		<h2>Properties</h2>


		<h3>[property:Vector3 start]</h3>

		<h3>[property:Vector3 end]</h3>

		<h2>Methods</h2>


		<h3>[method:Line3 set]( [page:Vector3 start], [page:Vector3 end] )</h3>
		<div>
		start -- [page:Vector3] <br />
		end -- [page:Vector3]
		</div>
		<div>
		Sets the start and end values by copying the provided vectors.
		</div>

		<h3>[method:Line3 copy]( [page:Line3 line] )</h3>
		<div>
		line -- [page:Line3]
		</div>
		<div>
		Copies the passed line's start and end vectors to this line.
		</div>

		<h3>[method:Line3 clone]()</h3>
		<div>
		Return a new copy of this [page:Line3].
		</div>

		<h3>[method:Boolean equals]( [page:Line3 line] )</h3>
		<div>
		line -- [page:Line3]
		</div>
		<div>
		Returns true if both line's start and end points are equal.
		</div>

		<h3>[method:Float distance]()</h3>
		<div>
		Returns the length of the line segment.
		</div>

		<h3>[method:Float distanceSq]()</h3>
		<div>
		Returns the line segment's length squared.
		</div>

		<h3>[method:Line3 applyMatrix4]( [page:Matrix4 matrix] ) [page:Line3 this]</h3>
		<div>
		matrix -- [page:Matrix4]
		</div>
		<div>
		Apply a matrix transform to the line segment.
		</div>

		<h3>[method:Vector3 at]( [page:Float t], [page:Vector3 optionalTarget] )</h3>
		<div>
		t -- [page:Float] Use values 0-1 to return a result on the line segment. <br />
		optionalTarget -- [page:Vector] Optional target to set the result.
		</div>
		<div>
		Return a vector at a certain position along the line. When t = 0, it returns the start vector, and when t=1 it returns the end vector.
		</div>

		<h3>[method:Vector3 getCenter]( [page:Vector3 optionalTarget] )</h3>
		<div>
		optionalTarget -- [page:Vector3] Optional target to set the result.
		</div>
		<div>
		Return the center of the line segment.
		</div>

		<h3>[method:Vector3 delta]( [page:Vector3 optionalTarget] )</h3>
		<div>
		optionalTarget -- [page:Vector3] Optional target to set the result.
		</div>
		<div>
		Returns the delta vector of the line segment, or the end vector minus the start vector.
		</div>

		<h3>[method:Vector3 closestPointToPoint]( [page:Vector3 point], [page:Boolean clampToLine], [page:Vector3 optionalTarget] )</h3>
		<div>
		point -- [page:Vector3] <br />
		clampToLine -- [page:Boolean] <br />
		optionalTarget -- [page:Vector3] Optional target to set the result.
		</div>
		<div>
		Returns the closets point on the line. If clamp to line is true, then the returned value will be clamped to the line segment.
		</div>

		<h3>[method:Float closestPointToPointParameter]( [page:Vector3 point], [page:Boolean clampToLine] )</h3>
		<div>
		point -- [page:Vector3] <br />
		clampToLine -- [page:Boolean]
		</div>
		<div>
		Returns a point parameter based on the closest point as projected on the line segement. If clamp to line is true, then the returned value will be between 0 and 1.
		</div>
