如何在three.js中使用file api创建材质纹理

var fileInput = document.createElement('input');
fileInput.type = 'file';
fileInput.addEventListener('change', function(event) {
  var file = event.target.files[0];
  var reader = new FileReader();
  reader.onload = function(event) {
    var texture = new THREE.TextureLoader().load(event.target.result);
    // 在这里可以将纹理应用到材质上
  };
  reader.readAsDataURL(file);
});
fileInput.click();

var geometry = new THREE.PlaneGeometry(10, 10);
var material = new THREE.MeshBasicMaterial({ map: texture });
var plane = new THREE.Mesh(geometry, material);
scene.add(plane);

function animate() {
  requestAnimationFrame(animate);
  renderer.render(scene, camera);
  // 在每一帧更新纹理
  texture.needsUpdate = true;
}
animate();
