bezier-forward-diff

Bezier subdivision via forward differencing

install

npm install bezier-forward-diff

use

var bezier = require('./bezier');
var zeroes = require('zeroes');

var input = [ [ 0, 0, 0 ],
[ 0, 0, 1 ],
[ 0, 1, 1 ],
[ 1, 1, 1 ] ];

var segments = 7;

// preallocate the result array
var result = zeroes( [ segments + 1, 3 ] ); // n + 1 points define n segments

bezier(result, input, segments);

console.log(result);
