Angle Between Landmarks

This is a lightweight library that is capable to calculate the degree angle between three landmarks.

Note: "Landmarks2" must be the origin as shown in the picture and all the landmarks must be normalized according to the screen.

Installation

Install angle-between-landmarks with npm/yarn

  npm install angle-between-landmarks // npm
  yarn add angle-between-landmarks // yarn

Usage/Examples

Import

import findAngle from 'angle-between-landmarks'; // ES6
const findAngle = require('angle-between-landmarks'); // CommonJS

Data

const landmarks1 = { x: 0, y: 0 };
const landmarks2 = { x: 1, y: 0 }; // Middle one must be the origin
const landmarks3 = { x: 1, y: 1 };
const opt = { small: false, round: true} // default { small: false, round: true }

Usage

let anngle = findAngle(landmarks1, landmarks2, landmarks3, opt);
