HTML并不支持3D图形的渲染,需要使用JavaScript和CSS等技术来实现。以下是一个基于Three.js库实现的3D烟花代码的示例:
HTML代码:
```html
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>3D烟花</title>
<style>
body {
margin: 0;
overflow: hidden;
}
canvas {
width: 100%;
height: 100%;
}
</style>
</head>
<body>
<script src="https://cdn.bootcdn.net/ajax/libs/three.js/r128/three.min.js"></script>
<script src="./firework.js"></script>
</body>
</html>
```
JavaScript代码(保存为firework.js文件):
```javascript
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(
75,
window.innerWidth / window.innerHeight,
0.1,
1000
);
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
const geometry = new THREE.SphereGeometry(1, 32, 32);
const material = new THREE.MeshBasicMaterial({ color: 0xffffff });
const sphere = new THREE.Mesh(geometry, material);
scene.add(sphere);
camera.position.z = 5;
function animate() {
requestAnimationFrame(animate);
sphere.rotation.x += 0.01;
sphere.rotation.y += 0.01;
renderer.render(scene, camera);
}
animate();
```
这个示例代码中,我们使用Three.js库创建了一个球体,并通过旋转来模拟烟花的效果。你可以根据自己的需求修改代码,实现更加丰富的3D烟花效果。
