Getting started

Web browser :

	<script src="node_module/v128/dist/v128-min.js"></script>

Node.js :

const {v128} = require("v128");

await v128.init(4);
let cameraPos = v128.vector.new(0,2.5,-4);
let center = v128.vector.new(0,0,0);
let up = v128.vector.new(0,1,0);
let viewMatrix = v128.matrix.lookAt(cameraPos,center,up,v128.matrix.new());
let projectionMatrix = v128.matrix.perspective(Math.PI/2,4/3,0.1,1000,v128.matrix.new());
let viewProjection = v128.matrix.multiply(viewMatrix, projectionMatrix,v128.matrix.new());
