gmatrix.js

Usage

import { v2, v3, v4, q4, m4 } from "./gmatrix.js"   // or "./gmatrix.min.js"

// Create new objects
let vec = new v4(), mat = new m4();

// Chain operations
console.log( mat.multVec4( vec ).equals( new v4() ) ); // true

Create new or mutate old

let c = v4.sub( a, b );   // returns a new vector from the v4 class object
c.sub( d );               // actually mutates c

Other notable functions

let m = new m4( 3 );    // passing a scalar to the m4 constructor *scales* the identity matrix by that factor
let p = new v2().copy( anotherVector );        // copy values from other vectors
let g = p.clone();                             // or clone them
let start = new v4().distanceTo( end );        // lots of useful operations, check out the source
