Nessworthy / decasteljau
========================

[](#nessworthy--decasteljau)

A stupid way of using [De Casteljau's algorithm](https://en.wikipedia.org/wiki/De_Casteljau's_algorithm) to calculate control points of a segment in a cubic bezier curve in PHP.

I used this a fair amount when trying to work out segments for SVG paths.

Requirements
------------

[](#requirements)

- PHP 7

Installation
------------

[](#installation)

`composer require nessworthy/decasteljau`

Usage
-----

[](#usage)

The algorithm requires 6 pieces of information - the original 4 control points of your bezier curve, where you want to cut your segment, and how long you want your segment to be.

Example:
