如何更新Typescript中的three.js BufferGeometry位置

import * as THREE from 'three';

const geometry = new THREE.BufferGeometry();
const positions = new Float32Array([
  -1.0, -1.0, 0.0,
  1.0, -1.0, 0.0,
  0.0, 1.0, 0.0
]);
geometry.setAttribute('position', new THREE.BufferAttribute(positions, 3));

const positions = geometry.getAttribute('position').array as Float32Array;
positions[0] += 0.1; // 将第一个顶点的x坐标增加0.1
geometry.getAttribute('position').needsUpdate = true; // 标记位置属性已更新

const renderer = new THREE.WebGLRenderer();
// 设置渲染器的大小等相关属性
// ...

function animate() {
  requestAnimationFrame(animate);
  
  // 更新BufferGeometry的位置属性
  // ...
  
  renderer.render(scene, camera);
}

animate();
