3D粒子爱心3D颗粒代码
创建一个3D爱心跳动效果通常涉及到HTML、CSS和JavaScript(特别是动画和一些前端框架如Three.js)。下面是一个简单的例子,展示如何使用HTML5 canvas和JavaScript实现一个基础的3D爱心形状在网页上跳动:
```html
<!DOCTYPE html>
<html lang="en">
<head>
<style>
#canvas {
display: block;
margin: auto;
background-color: #f0f0f0;
}
</style>
</head>
<body>
<canvas id="heartCanvas" width="400" height="400"></canvas>
<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r128/three.min.js"></script>
<script>
var scene, camera, renderer, heartGeometry, heartMaterial, heartMesh;
function init() {
scene = new THREE.Scene();
camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 5;
renderer = new THREE.WebGLRenderer({antialias: true});
renderer.setSize(window.innerWidth, window.innerHeight);
document.getElementById("heartCanvas").appendChild(renderer.domElement);
// 生成爱心几何体
heartGeometry = new THREE.IcosahedronGeometry(1, 4);
heartMaterial = new THREE.MeshBasicMaterial({color: 0xff0000}); // 红色
heartMesh = new THREE.Mesh(heartGeometry, heartMaterial);
heartMesh.rotation.y = Math.PI; // 转向屏幕
scene.add(heartMesh);
}
function animate() {
requestAnimationFrame(animate);
// 模拟爱心跳动
heartMesh.rotation.x += 0.01;
heartMesh.scale.set(1 + Math.sin(Date.now() * 0.02) * 0.1, 1, 1); // 弹跳效果
renderer.render(scene, camera);
}
window.onload = function() {
init();
animate();
};
</script>
</body>
</html>
```
这个示例中的代码创建了一个红色的心形物体,它会随着页面加载并在x轴上旋转,并且有一定的垂直上下弹跳效果。
