修改
我发现只要我想添加HelperBox就会出现巨型盒子，我制作了a JSFiddle，这里没有任何东西会影响第二个盒子的大小。然而，在我的代码中，有一些东西干扰了我的盒子，因为当我将Helper添加到场景时它会弄乱我的第二个盒子，你可以在这里看到：你可以看到巨型盒子的轮廓{{3}如果我再缩小一些你可以看到他们全部被覆盖on this screenshot我无法弄清楚为什么会发生这种情况......特别是因为JSFiddle工作正常。 （或许盒子的乱七八糟的轮廓是一个指示物？）
ORIGINAL
我试图检查三个盒子中两个盒子的碰撞，我得到了一些结果，我并没有期待并实现了THREE.BoxHelper。当我在我的第一个盒子上使用它时，没有什么不对，但是当我在第二个盒子上添加帮助器时，它显得如此巨大......我似乎无法找到我出错的地方。我的基础是in the giant blue box.。
我在视觉上得到的截图：
这是触发此操作的代码的主要部分：
const makeTestCube = () => {
testBox = new THREE.Mesh(
new THREE.BoxGeometry(3, 3, 3),
new THREE.MeshBasicMaterial({color: 0xFF0099})//PINK
);
testBox.position.set(0, 0, 20);
testBoxBbox = new THREE.Box3(new THREE.Vector3(), new THREE.Vector3());
testBoxBbox.setFromObject(testBox);
const testBoxHelper = new THREE.BoxHelper(testBoxBbox, 0xCC6600); //ORANGE
testBox.geometry.computeBoundingBox();
scene.add(testBox);
scene.add(testBoxHelper);
};
const makeAnotherTestCube = () => {
anotherTestBox = new THREE.Mesh(
new THREE.BoxGeometry(3, 3, 3),
new THREE.MeshBasicMaterial({color: 0x990000})//RED This is the small box in the giant box
);
anotherTestBox.position.set(0, 0, 30);
anotherTestBoundingBox = new THREE.Box3(new THREE.Vector3(), new THREE.Vector3());
anotherTestBoundingBox.setFromObject(anotherTestBox);
const anotherTestBoxHelper = new THREE.BoxHelper(anotherTestBox, 0xCC6600);// This is the giant box (Orange)
anotherTestBox.geometry.computeBoundingBox();
scene.add(anotherTestBox);
scene.add(anotherTestBoxHelper);
};

没有冒犯，你的变量名很糟糕。对于这里的内容，令人难以置信的困惑。
试试这个。改变这一行：
const anotherTestBoxHelper = new THREE.BoxHelper(anotherTestBox, 0xCC6600);
要：
const anotherTestBoxHelper = new THREE.BoxHelper(anotherTestBoundingBox, 0xCC6600);
答案 1 :(得分：0)
禁用这段代码为我修复了它，但不了解原因。
renderer.shadowMap.enabled = true;
renderer.shadowMap.type = THREE.PCFSoftShadowMap;
renderer.gammaInput = true;
renderer.gammaOutput = true;
renderer.setClearColor(0xdddddd, 1);
