bezier-intersect  

Set of functions to find intersections between lines and rectangles and Bezier curves of order 2 and 3. Based on thelonious/js-intersections, but with the abstractions removed and some performance tweaking.

Install

``
npm i -S bezier-intersect

API

$3

Calculates the intersection points between the quadratic Bezier curve and line segment. If result is passed, returns the exact number of intersections, and stores them in result as [x, y, x, y]. If not - stops at the first intersection and returns 1 or 0 if there are no intersections.

$3

Calculates the intersection points between the quadratic Bezier curve and axis-aligned box. If result is passed, returns the exact number of intersections, and stores them in result as [x, y, x, y]. If not - stops at the first intersection and returns 1 or 0 if there are no intersections.

$3

$3
