HTML 3D 圖片是一種新型的圖片處理方式,它可以讓圖片在網(wǎng)頁(yè)上呈現(xiàn)出三維效果,增強(qiáng)用戶的視覺體驗(yàn)。這種技術(shù)采用了HTML5的canvas標(biāo)簽和JavaScript的three.js庫(kù)。
要實(shí)現(xiàn)3D圖片,需要先導(dǎo)入three.js庫(kù),并將canvas元素添加到HTML頁(yè)面上:
<script src="js/three.min.js"></script>
<canvas id="canvas"></canvas>
接下來,需要設(shè)置3D視圖,即通過設(shè)置場(chǎng)景、相機(jī)、光源等元素來創(chuàng)建3D場(chǎng)景:var scene = new THREE.Scene();
var camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
var renderer = new THREE.WebGLRenderer({canvas: document.getElementById("canvas")});
renderer.setSize(window.innerWidth, window.innerHeight);
var ambientLight = new THREE.AmbientLight(0x404040);
var directionalLight = new THREE.DirectionalLight(0xffffff, 0.5);
directionalLight.position.set(0, 1, 0);
scene.add(ambientLight);
scene.add(directionalLight);
在場(chǎng)景中添加對(duì)象是創(chuàng)建3D圖像的核心。這里我們創(chuàng)建一個(gè)立方體,并設(shè)置其顏色和位置:var cubeGeometry = new THREE.BoxGeometry(1, 1, 1);
var cubeMaterial = new THREE.MeshLambertMaterial({color: 0xff0000});
var cube = new THREE.Mesh(cubeGeometry, cubeMaterial);
cube.position.y = 1;
scene.add(cube);
最后,渲染3D場(chǎng)景即可呈現(xiàn)出3D圖片:function render() {
requestAnimationFrame(render);
cube.rotation.x += 0.01;
cube.rotation.y += 0.01;
renderer.render(scene, camera);
}
render();
以上是一個(gè)簡(jiǎn)單的示例,有了基礎(chǔ)的了解之后,就可以嘗試制作更加復(fù)雜的3D圖片了。
