- <div class="desc">An extensible curve object which contains methods for interpolation.</div>
- <h2>Constructor</h2>

- </div>
- <h2>Methods</h2>
- <h3>.getPoint ( t )</h3>
- <div>Returns a vector for point t of the curve where t is between 0 and 1</div>
- <h3>.getPointAt ( u )</h3>
- <div>Returns a vector for point at relative position in curve according to arc length</div>
- <h3>.getPoints ( divisions )</h3>
- <div>Get sequence of points using getPoint( t ) </div>
- <h3>.getSpacedPoints ( divisions )</h3>
- <div>Get sequence of equi-spaced points using getPointAt( u )</div>
- <h3>.getLength ()</h3>
- <div>Get total curve arc length</div>
- <h3>.getLengths ( divisions )</h3>
- <div>Get list of cumulative segment lengths</div>
- <h3>.updateArcLengths ()</h3>
- <div>Update the cumlative segment distance cache</div>
- <h3>.getUtoTmapping ( u, distance )</h3>
- <div>Given u ( 0 .. 1 ), get a t to find p. This gives you points which are equidistant</div>
- <h3>.getTangent ( t )</h3>
- <div>Returns a unit vector tangent at t. If the subclassed curve do not implement its tangent derivation, 2 points a small delta apart will be used to find its gradient which seems to give a reasonable approximation</div>
- <h3>.getTangentAt ( u )</h3>
- <div>Returns tangent at equidistant point u on the curve</div>
