ai转头抬头 ai怎么做旋转箭头

const scene = new THREE.Scene;

const aiModel = loadAIModel; // 加载AI模型

// 转头抬头控制

function rotateHead(horizontal, vertical) {

aiModel.neck.rotation.y = horizontal; // 左右转头

aiModel.head.rotation.x = vertical; // 上下抬头

// 箭头旋转控制

const arrow = new THREE.Mesh(

new THREE.ConeGeometry(0.5, 2, 4),

new THREE.MeshBasicMaterial({color: 0xff0000})

);

arrow.rotation.z = Math.PI/2; // 初始旋转

function rotateArrow(angle) {

arrow.rotation.z = angle;
