js插件实现三维柱状图

// 引入Three.js库
import * as THREE from 'three';

// 创建场景
const scene = new THREE.Scene();

// 创建相机
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;

// 创建渲染器
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);

// 创建柱状图数据
const data = [1, 2, 3, 4, 5];
const geometry = new THREE.BoxGeometry(1, 1, 1);
const material = new THREE.MeshBasicMaterial({ color: 0x00ff00 });

data.forEach((value, index) => {
    const cube = new THREE.Mesh(geometry, material);
    cube.position.x = index * 2 - (data.length - 1);
    cube.scale.y = value;
    scene.add(cube);
});

// 渲染循环
function animate() {
    requestAnimationFrame(animate);
    renderer.render(scene, camera);
}
animate();
