intersectsBoxがfalseを返すとtrueを返します

Question

MDNの説明に従って、境界ボックスの交差をチェックしていました。あなたは2つの緑色のボックスが交差しないと、まだ彼らが...誰かですログインしています。このスクリーンショットで見ることができるように

const testBoxGeometry = new THREE.BoxGeometry(3, 3, 3); 
    const testBoxMaterial = new THREE.MeshBasicMaterial({color: 0x00ff00}); 
    testBox = new THREE.Mesh(testBoxGeometry, testBoxMaterial); 
    testBox.geometry.computeBoundingBox(); 
    testBoundingBox = new THREE.Box3(
    testBox.geometry.boundingBox.min, 
    testBox.geometry.boundingBox.max 
); 
    testBox.position.set(5, 0, 5); 
    scene.add(testBox); 

    const cameraBoxGeometry = new THREE.BoxGeometry(3, 3, 3); 
    const cameraBoxMaterial = new THREE.MeshBasicMaterial({color: 0x00ff00}); 
    cameraBox = new THREE.Mesh(cameraBoxGeometry, cameraBoxMaterial); 
    cameraBox.geometry.computeBoundingBox(); 
    cameraBoundingBox = new THREE.Box3(
    cameraBox.geometry.boundingBox.min, 
    cameraBox.geometry.boundingBox.max 
); 
    scene.add(cameraBox); 

そして、私のアニメーション機能で

if (testBoundingBox.intersectsBox(cameraBoundingBox)) { 
    console.log(`intersection`); 
    } 

：だから私は、コードを書きました私が間違ってやっていることを知っているかもしれないし、これをデバッグする方向に私を押し込むかもしれない？

EDIT

Hectateが述べたように、私はsetFromObjectを（）を追加する必要があり、これが私の最初の問題を修正します。しかし、今私は新しい問題を抱えています。私が使用する最初の四角は私のカメラを表すからです。私は環境を作り、プレイヤー（一人目をシミュレートするカメラ）がそのエリア内のどのオブジェクトにも衝突しているかどうかを確認したい。私はObject3D（）を作成し、カメラと正方形を追加することでこれを行います。私は正方形を見えないようにしますが、衝突を検出するための境界に使用します。

プレーヤーObject3Dを翻訳（私は翻訳用に翻訳しています）していますので、私の元の位置は変わらず、交差点は常にORしか起こりません。

私は私のプレーヤーObject3Dをナビゲートするために使用しているコード：

if (moveForward) player.translateZ(- .05); 
if (moveBackward) player.translateZ(.05); 
if (moveLeft) player.translateX(- .05); 
if (moveRight) player.translateX(.05); 

EDIT 2

：キーは私のアニメーション機能に

switch (e.key) { 
case `z`: 
    moveForward = true; 
    break; 
case `s`: 
    moveBackward = true; 
    break; 
case `q`: 
    moveLeft = true; 
    break; 
case `d`: 
    moveRight = true; 
    break; 
}

あなたがリンク先の記事には、以下の注意事項が含まれていました。

注：このBoundingBoxプロパティをメッシュを基準として、ジオメトリ自体を取り、ではありません。したがって、メッシュに適用されるスケール、位置などの変換は、計算ボックスの計算中は無視されます。

それに続いて、私はsetFromObject()を使用してtestBoundingBoxの位置を設定し、期待通りにトリガーしませんでした。ここに興味深いコードだけでなく、動作を示すjsfiddleがあります。ボックスの位置を変更して、もちろん、interectionsトリガーを見るために再実行してください。あなたの編集に対応して
