当我使用它作为一个立方体和一个球体的代码时，它会切掉这个立方体的某些部分：

    <!DOCTYPE html>

<html>

<head>

<script type="text/javascript" src="csg.js"></script>
<script type="text/javascript" src="http://chandler.prallfamily.com/threebuilds/builds/r46/ThreeMin.js"></script>
<script type="text/javascript" src="ThreeCSG.js"></script>

<script type="text/javascript">

window.onload = function() {

var projector = new THREE.Projector( );
var renderer = new THREE.WebGLRenderer({antialias: false});
renderer.setSize(800, 640);

document.getElementById('viewport').appendChild(renderer.domElement);

var scene = new THREE.Scene();

var camera = new THREE.PerspectiveCamera(
    35,
    800 / 640,
    1,
    10000
);
camera.position.set(5, 1.8, 5);
camera.lookAt(scene.position);

var cube = THREE.CSG.toCSG(
    new THREE.CubeGeometry( 2, 2, 2 ),
    new THREE.Vector3(-1, 0, 0)
);
var sphere = THREE.CSG.toCSG(new THREE.SphereGeometry(1.4, 16, 16));
var geometry = cube.subtract(sphere);
var mesh = new THREE.Mesh(
    THREE.CSG.fromCSG( geometry ),
    new THREE.MeshNormalMaterial()
);
scene.add( mesh );

renderer.render(scene, camera);

}

</script>

</head>

<body>

<div id="viewport"></div>

</body>

</html>

我现在如何设置立方体的位置？我需要像 cube.CSG.position.set 这样的东西还是 CSG 库有一个特殊的方法可以使用？

谢谢！

您需要在设置渲染器后调用一个函数，例如：

animate();

像这样定义它：

function animate()
{
    requestAnimationFrame(animate);
    cube.position.x = your_value;
}
