如何改变three.js筒体的厚度

var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);

var geometry = new THREE.CylinderGeometry(radiusTop, radiusBottom, height, radialSegments, heightSegments, openEnded);

var material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });
var cylinder = new THREE.Mesh(geometry, material);
scene.add(cylinder);

var renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

function animate() {
    requestAnimationFrame(animate);
    // 在这里可以添加旋转、平移等动画效果
    renderer.render(scene, camera);
}
animate();
