Question

这是ThreeJs渲染视图，只是我想根据移动设备/宽度缩放渲染视图。

var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(
  120,
  window.innerWidth / window.innerHeight,
  0.1,
  1000
);

var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

var geometry = new THREE.Geometry(1, 1, 1);
geometry.vertices.push(new THREE.Vector3(-2, 0, 0));
geometry.vertices.push(new THREE.Vector3(0, 2, 0));
geometry.vertices.push(new THREE.Vector3(2, 0, 0));
geometry.vertices.push(new THREE.Vector3(-2, 0, 0));
geometry.vertices.push(new THREE.Vector3(0, 2, 0));
geometry.vertices.push(new THREE.Vector3(2, 0, 0));
var material = new THREE.MeshBasicMaterial({
  color: 0x00ff00
});
var line = new THREE.Line(geometry, material);
scene.add(line);

camera.position.z = 5;

function animate() {
  requestAnimationFrame(animate);
  line.rotation.x += 0.1;
  line.rotation.y += 0.8;
  // line.rotation.z += 0.5;
  renderer.render(scene, camera);
}

animate();

body {
  margin: 0;
}

canvas {
  width: 100%;
  height: 100%;
}
