html3d炫彩地球儀代碼

HTML3D是一種基于HTML5的3D技術,它可以讓開發者創建出驚人的3D場景和效果。其中,炫彩地球儀是HTML3D技術的一種常見實現,也被廣泛應用于Web開發中。

如果你想了解如何使用HTML3D來創建一個炫彩地球儀,可以參考以下代碼:

<!DOCTYPE html>
<html>
<head>
	<title>HTML3D炫彩地球儀</title>
	<style>
body { margin: 0; padding: 0; overflow: hidden; }
canvas { width: 100%; height: 100%; }
	</style>
</head>
<body>
	<canvas id="canvas"></canvas>
<script src="https://cdn.rawgit.com/mrdoob/three.js/r92/build/three.min.js"></script>
	<script src="https://cdn.rawgit.com/mrdoob/three.js/r92/examples/js/controls/OrbitControls.js"></script>
	<script src="https://cdn.rawgit.com/mrdoob/three.js/r92/examples/js/Detector.js"></script>
	<script>
// 判斷瀏覽器是否支持WebGL
if ( ! Detector.webgl ) Detector.addGetWebGLMessage();
var renderer, camera, scene, earth, moon;
// 初始化場景
function init() {
// 創建渲染器
renderer = new THREE.WebGLRenderer({ canvas: document.getElementById('canvas'), antialias: false });
renderer.setSize(window.innerWidth, window.innerHeight);
renderer.setClearColor(0x000000, 1);
// 創建相機
camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 1, 1000);
camera.position.set(0, 0, 500);
camera.lookAt(new THREE.Vector3(0, 0, 0));
// 創建場景
scene = new THREE.Scene();
// 創建地球
var earthGeometry = new THREE.SphereGeometry(200, 50, 50);
var earthMaterial = new THREE.MeshPhongMaterial({
map: new THREE.TextureLoader().load('https://cdn.rawgit.com/mrdoob/three.js/r92/examples/textures/land_ocean_ice_cloud_2048.jpg'),
specularMap: new THREE.TextureLoader().load('https://cdn.rawgit.com/mrdoob/three.js/r92/examples/textures/water_256x256.jpg'),
specular: new THREE.Color('grey')
});
earth = new THREE.Mesh(earthGeometry, earthMaterial);
scene.add(earth);
// 創建月球
var moonGeometry = new THREE.SphereGeometry(50, 50, 50);
var moonMaterial = new THREE.MeshPhongMaterial({
map: new THREE.TextureLoader().load('https://cdn.rawgit.com/mrdoob/three.js/r92/examples/textures/moon_1024.jpg')
});
moon = new THREE.Mesh(moonGeometry, moonMaterial);
moon.position.set(300, 0, 0);
scene.add(moon);
// 創建光源
var light = new THREE.DirectionalLight(0xffffff);
light.position.set(100, 0, 0);
scene.add(light);
// 創建控制器
var controls = new THREE.OrbitControls(camera, renderer.domElement);
}
// 渲染場景
function render() {
requestAnimationFrame(render);
earth.rotation.y += 0.002;
moon.rotation.y += 0.01;
renderer.render(scene, camera);
}
// 初始化并渲染場景
function start() {
init();
render();
}
// 開始
start();
	</script>
</body>
</html>

這段代碼使用了Three.js庫來進行3D渲染,并在其中實現了炫彩地球儀的效果。其中,通過創建相機、場景、地球和月球等元素,可以實現一個簡單的3D場景。同時,在渲染場景的過程中,通過控制元素的旋轉角度,可以讓場景呈現出更加逼真的3D效果。

總的來說,HTML3D技術在Web開發中有著廣泛的應用,通過熟練掌握相關的技術和代碼實現,可以為網站帶來更加炫酷、動態的效果,提高用戶體驗。
