我做了一些研究并学习了如何将 obj 文件导出为可以通过 Three.js 的 JSON 模型导入的 .js 文件。但是你怎么能动画这样的模型呢？我有一个 .js 格式的鸟类模型，我需要学习扇动翅膀。此外，当我从互联网下载 obj 文件时，因为它是免费模型，它还包含对象的纹理图像，但是当我在 3d 建模软件 Blender 3d 中导入 obj 时，它无法加载纹理，但它的位置就在里面obj 文件，当我从文本编辑器打开它时。当我将其转换为 .js 格式时，它还具有位于 bmp 图像的正确位置以进行纹理映射，但是当我使用 JSON 模型在 webgl 中加载模型时无法加载。

任何人都可以从我可以学习所有这些想法的地方指出我正确的方向，如果您知道并立即帮助我回答，那就太好了。拜托，我需要你们的帮助。

看看这里

http://threejs.org/examples/webgl_morphnormals.html http://threejs.org/examples/webgl_morphtargets_horse.html

在第一个例子中看这里，第 90 行

var loader = new THREE.JSONLoader();
                loader.load( "models/animated/flamingo.js", function( geometry ) {

                    morphColorsToFaceColors( geometry );
                    geometry.computeMorphNormals();

                    var material = new THREE.MeshLambertMaterial( { color: 0xffffff, morphTargets: true, morphNormals: true, vertexColors: THREE.FaceColors, shading: THREE.FlatShading } );
                    var meshAnim = new THREE.MorphAnimMesh( geometry, material );

                    meshAnim.duration = 5000;

                    meshAnim.scale.set( 1.5, 1.5, 1.5 );
                    meshAnim.position.y = 150;

                    scene1.add( meshAnim );
                    morphs.push( meshAnim );

                } );
