我一直在尝试制作一个导出代码，以便快速让我纹理立方体并将它们导出到我正在制作的游戏中，但由于某种原因，我无法让我的立方体覆盖整个 128x128我希望它具有的宽度和高度。
我有以下代码：
function init(){
if( Detector.webgl ){
renderer = new THREE.WebGLRenderer({
antialias : false, // to get smoother output
preserveDrawingBuffer : true // to allow screenshot
});
renderer.setClearColorHex( 0xBBBBBB, 1 );
// uncomment if webgl is required
//}else{
// Detector.addGetWebGLMessage();
// return true;
}else{
renderer = new THREE.CanvasRenderer();
}
renderer.setSize(128,128);
document.getElementById('container').appendChild(renderer.domElement);
// add Stats.js - https://github.com/mrdoob/stats.js
stats = new Stats();
stats.domElement.style.position = 'absolute';
stats.domElement.style.bottom = '0px';
document.body.appendChild( stats.domElement );
var zoom = 1.0;
// create a scene
scene = new THREE.Scene();
// put a camera in the scene
camera = new THREE.OrthographicCamera(WIDTH / -zoom, HEIGHT / zoom, WIDTH / zoom, HEIGHT / -zoom, -2000, 1000);
//camera = new THREE.PerspectiveCamera(35, window.innerWidth / window.innerHeight, 1, 10000 );
camera.position.set(0.45,0.45,0.45);
camera.lookAt(scene.position);
//camera.position.set(0, 0, 5);
scene.add(camera);
// create a camera contol
//cameraControls = new THREEx.DragPanControls(camera)
// transparently support window resize
THREEx.WindowResize.bind(renderer, camera);
// allow 'p' to make screenshot
THREEx.Screenshot.bindKey(renderer);
// allow 'f' to go fullscreen where this feature is supported
//if( THREEx.FullScreen.available() ){
// THREEx.FullScreen.bindKey();
// document.getElementById('inlineDoc').innerHTML += "- <i>f</i> for fullscreen";
//}
// here you add your objects
// - you will most likely replace this part by your own
//var geometry = new THREE.TorusGeometry( 1, 0.42 );
var cubeSize = 128;
var geometry = new THREE.CubeGeometry( cubeSize, cubeSize, cubeSize );
var material = new THREE.MeshNormalMaterial();
mesh= new THREE.Mesh( geometry, material );
mesh.rotation.x = 0;
mesh.rotation.y = 0;
mesh.rotation.z = 0;
scene.add( mesh );
}
我一直在尝试不同的“缩放”，但最终还是太大或太小。所有这一切的重点是最终得到一个可以生成如下内容的代码：

我究竟做错了什么？
