实现代码

<!DOCTYPE html>
<html>
	<head>
		<meta charset="utf-8">
		<title>My first three.js app</title>
		<style> body {
       margin: 0; } #info {
       position: absolute; top: 100px; width: 100%; text-align: center; z-index: 100; display:block; color: #fff; } </style>
	</head>
	<body>
        <div id="info">Description</div>
		<script src="./index_script/index_script_three.js"></script>
		<script> const renderer = new THREE.WebGLRenderer(); renderer.setSize( window.innerWidth, window.innerHeight ); document.body.appendChild( renderer.domElement ); const camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 500 ); camera.position.set( 0, 0, 100 ); camera.lookAt( 0, 0, 0 ); const scene = new THREE.Scene(); //create a blue LineBasicMaterial const material = new THREE.LineBasicMaterial( {
       color: 0xe4e4e4 } ); const points = []; points.push( new THREE.Vector3( - 10, 0, 0 ) ); points.push( new THREE.Vector3( 0, 10, 0 ) ); points.push( new THREE.Vector3( 10, 0, 0 ) ); const geometry = new THREE.BufferGeometry().setFromPoints( points ); const line = new THREE.Line( geometry, material ); scene.add( line ); function animate() {
       requestAnimationFrame( animate ); renderer.render( scene, camera ); }; animate(); </script>
	</body>
</html>
