3D粒子爱心动画可以使用WebGL和Three.js库来实现。以下是一个简单的示例代码,用于创建一个3D粒子爱心动画。
HTML部分:
```
<!DOCTYPE html>
<html>
<head>
<title>3D Particle Heart Animation</title>
<script src="https://cdnjs.cloudflare.com/ajax/libs/three.js/r128/three.min.js"></script>
</head>
<body>
<canvas id="canvas"></canvas>
<script src="particle_heart.js"></script>
</body>
</html>
```
JS部分(particle_heart.js):
```
// 创建场景
var scene = new THREE.Scene();
// 创建渲染器
var renderer = new THREE.WebGLRenderer({
canvas: document.getElementById("canvas"),
antialias: true
});
// 设置渲染器大小
renderer.setSize(window.innerWidth, window.innerHeight);
// 创建摄像机
var camera = new THREE.PerspectiveCamera(
45,
window.innerWidth / window.innerHeight,
1,
10000
);
camera.position.set(0, 0, 1000);
// 创建粒子材质
var material = new THREE.PointsMaterial({
color: "red",
size: 10
});
// 创建粒子系统
var geometry = new THREE.Geometry();
var particleCount = 2000;
for (var i = 0; i < particleCount; i++) {
var x = Math.random() * 2000 - 1000;
var y = Math.random() * 2000 - 1000;
var z = Math.random() * 2000 - 1000;
var particle = new THREE.Vector3(x, y, z);
geometry.vertices.push(particle);
}
// 将粒子系统添加到场景中
var particles = new THREE.Points(geometry, material);
scene.add(particles);
// 渲染场景
function render() {
requestAnimationFrame(render);
particles.rotation.x += 0.001;
particles.rotation.y += 0.001;
renderer.render(scene, camera);
}
render();
```
