class Matrix4
implements Matrix
import { Matrix4 } from "https://deno.land/x/threejs_4_deno@v121/src/math/Matrix4.d.ts";

A 4x4 Matrix.

Examples

// Simple rig for rotating around 3 axes const m = new THREE.Matrix4(); const m1 = new THREE.Matrix4(); const m2 = new THREE.Matrix4(); const m3 = new THREE.Matrix4(); const alpha = 0; const beta = Math.PI; const gamma = Math.PI/2; m1.makeRotationX( alpha ); m2.makeRotationY( beta ); m3.makeRotationZ( gamma ); m.multiplyMatrices( m1, m2 ); m.multiply( m3 );
