Ich versuche, 3D-Modelle zu meiner Website hinzuzufügen. Ich verwende drei .js. Ich habe alles versucht, konnte aber das 3D-Modell nicht sichtbar machen. Auf der Registerkarte „Netzwerk“ der Entwicklertools kann ich sehen, dass die MTL- und OBJ-Dateien geladen sind, aber die Seite ist einfach leer. Ich habe drei verschiedene 3D-Modelle ausprobiert, aber das gleiche Problem besteht weiterhin. Ich werde jede Hilfe leisten.

通过将文件的 CDN 更改为更现代的 UNPKG CDN，从那里加载所有
two.js文件，并从您粘贴在评论上的 URL 加载 3D 模型，我能够成功加载文件。我还将对象的位置调整为 -5，将比例调整为 0.05。这是对我有用的代码：<html> <head> <title>3D Model</title> <style> html, body { margin: 0; background-color: white; overflow: hidden; } </style> </head> <body> <script src="https://unpkg.com/three@0.147.0/build/three.min.js"></script> <script src="https://unpkg.com/three@0.147.0/examples/js/controls/OrbitControls.js"></script> <script src="https://unpkg.com/three@0.147.0/examples/js/loaders/OBJLoader.js"></script> <script src="https://unpkg.com/three@0.147.0/examples/js/loaders/MTLLoader.js"></script> <script> const scene = new THREE.Scene(); const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.01, 10000); camera.position.set(0, 0, 5); camera.lookAt(scene.position); const renderer = new THREE.WebGLRenderer(); renderer.setSize(window.innerWidth, window.innerHeight); renderer.setClearColor(0xeeeeee); // Light gray background color document.body.appendChild(renderer.domElement); const light = new THREE.AmbientLight(); scene.add(light); const directionalLight = new THREE.DirectionalLight(0xffffff, 1); directionalLight.position.set(1, 1, 1).normalize(); scene.add(directionalLight); const controls = new THREE.OrbitControls(camera, renderer.domElement); var MTLLoader = new THREE.MTLLoader(); MTLLoader.load("https://elipptic5g.com/models/Silivri001/odm_textured_model_geo.mtl", function (material) { material.preload(); console.log(material) // Set the path for the OBJLoader var OBJLoader = new THREE.OBJLoader(); OBJLoader.setMaterials(material); OBJLoader.load("https://elipptic5g.com/models/Silivri001/odm_textured_model_geo.obj", function (object) { object.position.set(0, -5, 0); // Adjust the values as needed object.scale.set(0.05, 0.05, 0.05) object.rotation.x = -Math.PI / 2; console.log(object) scene.add(object); }); }); function animate() { requestAnimationFrame(animate); renderer.render(scene, camera); } animate(); </script> </body> </html>这是我在浏览器中看到的内容：
