// 1.创建场景 
const scene = new THREE.Scene();

// 2.创建相机
var width = window.innerWidth; //窗口宽度
var height = window.innerHeight; //窗口高度
var k = width / height; //窗口宽高比
const camera = new THREE.PerspectiveCamera(90, k, 1, 1000);
camera.position.set(0, 0, -200); //设置相机位置
camera.lookAt(0, 0, 0);
scene.add(camera);

// 3. 创建渲染器
const renderer = new THREE.WebGLRenderer();
renderer.setSize(width, height);
document.body.appendChild(renderer.domElement);
renderer.setClearColor(0x000000);

// 4. 创建物体
const geometry = new THREE.BoxGeometry(100, 100, 100); // 几何体
const material = new THREE.MeshBasicMaterial({ color: 0xb01ff0 }); // 材质
var cube = new THREE.Mesh(geometry, material);
scene.add(cube);// 注意要把创建好的物体添加到场景中
// 5. 鼠标交互
const controls = new THREE.OrbitControls(camera, renderer.domElement);

// GUI
const gui = new dat.GUI();

let attrs = {
    x: 5,
    y: 5,
    z: 5,
    opacity: 1
}
gui.add(attrs, "x", 1,20,1).name('X轴位置').onChange((val)=>{
    cube.position.x = val;
});
gui.add(attrs, "y", 1, 20, 1).name('Y轴位置').onChange((val)=>{
    cube.position.y = val;
});
gui.add(attrs, "z").onChange((val)=>{
    cube.position.z = val;
});
gui.add(attrs, "opacity").min(0).max(1).step(0.1).name("透明度")
// 6. 渲染 
function render() {
    requestAnimationFrame(render);
    renderer.render(scene, camera);
}
render()
