我创建了两个单独的 html 文档。其中渲染了 Three.js 场景和基本 html 页面。我的问题是如何正确组合它们？我的目标是在左角创建旋转的绿色立方体和移动的红色立方体，红色立方体将从左侧移动到右侧。当移动到灰色内容区域时，红色立方体应该是不可见的。
三。 js:
<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8>
<title>Cube_v2</title>
<style>
body { margin: 0; }
canvas { width: 100%; height: 100% }
</style>
</head>
<body>
<script src="build/three.js"></script>
<script>
var scene = new THREE.Scene();
scene.background = new THREE.Color( 0xf0f0f0 );
var camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );
var renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );
var geometry = new THREE.BoxGeometry( 1, 1, 1 );
var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
var cube = new THREE.Mesh( geometry, material );
//cube.position.x = 100;
//cube.translateX = 100;
//three.cube.position.x = 100;
scene.add( cube );
camera.position.z = 10;
camera.position.x = 10;
var geometry_2 = new THREE.BoxGeometry( 2, 2, 2 );
var material_2 = new THREE.MeshBasicMaterial( { color: 0xff0000 } );
var cube_2 = new THREE.Mesh( geometry_2, material_2 );
scene.add( cube_2 );
function animate() {
requestAnimationFrame( animate );
cube.rotation.y += 0.01;
cube_2.position.x += 0.05;
renderer.render( scene, camera );
}
animate();
</script>
</body>
</html>
注意:我尝试使用 cube.position.x 移动绿色立方体, cube.translateX和three.cube.position.x 。但这不起作用，所以我通过移动相机解决了这个问题，但我不认为这是正确的方法。
HTML 我想要导入场景的文档可以在这里找到 JSfiddle
最佳答案
如果您想在网页中实现 Three.js 场景，请在基本 HTML 页面中您想要的位置创建一个 div。
<div id="myScene"></div>
并在脚本中代替:
document.body.appendChild( renderer.domElement );
写:
document.getElementById("myScene").appendChild( renderer.domElement );
代码片段:
var scene = new THREE.Scene();
scene.background = new THREE.Color( 0xf0f0f0 );
var camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );
var renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
document.getElementById("myScene").appendChild( renderer.domElement );
var geometry = new THREE.BoxGeometry( 1, 1, 1 );
var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
var cube = new THREE.Mesh( geometry, material );
//cube.position.x = 100;
//cube.translateX = 100;
//three.cube.position.x = 100;
scene.add( cube );
camera.position.z = 10;
camera.position.x = 10;
var geometry_2 = new THREE.BoxGeometry( 2, 2, 2 );
var material_2 = new THREE.MeshBasicMaterial( { color: 0xff0000 } );
var cube_2 = new THREE.Mesh( geometry_2, material_2 );
scene.add( cube_2 );
function animate() {
requestAnimationFrame( animate );
cube.rotation.y += 0.01;
cube_2.position.x += 0.05;
renderer.render( scene, camera );
}
animate();canvas {
