js-parallel-curve

This library builds a curve parallel to the given curve.

A parallel curve is also called an offset curve and this is the preferred term in CAGD. In other geometric contexts, the term offset can also refer also to translation.

Add required

<script type="text/javascript" src="parallel-curve.js"></script>

Example of use

var points = [{x:350, y:75}, {x:379, y:161}, {x:469, y:161}, {x:397, y:215}];
var offset = 10;
var isLeft = true;

var parallel = ParallelCurve.create(points, offset, isLeft);

Also you can find examples in a demo directory.
