怎么让ThreeJS场景跟随浏览器大小自适应

场景跟随浏览器窗口大小自适应

function onWindowResize() {
    camera.aspect = window.innerWidth / window.innerHeight;
    camera.updateProjectionMatrix();
    renderer.setSize(window.innerWidth, window.innerHeight);
}

window.addEventListener('resize', this.onWindowResize, false);

加上这两句话即可
