使用ThreeJS网格进行补间最大缩放

// 创建场景、相机和渲染器
var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// 创建网格
var geometry = new THREE.BoxGeometry(1, 1, 1);
var material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
var cube = new THREE.Mesh(geometry, material);
scene.add(cube);

// 设置初始缩放比例
cube.scale.set(1, 1, 1);

// 创建补间动画
var targetScale = new THREE.Vector3(0.1, 0.1, 0.1);
var tween = new TWEEN.Tween(cube.scale).to(targetScale, 2000).easing(TWEEN.Easing.Quadratic.InOut);

// 动画循环
function animate() {
    requestAnimationFrame(animate);
    TWEEN.update();
    renderer.render(scene, camera);
}
animate();

// 启动补间动画
tween.start();
