threejs带有对象材质的线框

Question

我想获取从OBJMTLLoder加载的对象的线框，所以在这里我有如下代码

var loader = new THREE.OBJMTLLoader();
                loader.load( 'obj/male02/male02.obj', 'obj/male02/male02_dds.mtl', function ( object ) {

                    object.traverse( function ( child ) {

                    if ( child instanceof THREE.Mesh )
                    {
                    child.geometry.computeFaceNormals();
                    var  geometry = child.geometry;
                    console.log(geometry);
                    geometry.dynamic = true;
                    material = new THREE.MeshLambertMaterial();
                    mesh = new THREE.Mesh(geometry, material);
                    scene.add(mesh);

                    var useWireFrame = true;
                        if (useWireFrame) {
                            mesh.traverse(function (child) {
                                if (child instanceof THREE.Mesh) child.material.wireframe = true;
                            });
                        }

                    }

                    object.position.y = - 80;
                    scene.add( object );

                    });

                } );

这工作得很好，我可以看到对象上的线框，不幸的是，在这里，我的对象材质已更改为MeshLambertMaterial 。 但是我想使用已加载对象的默认材质来获取对象的线框，我可以像在threejs文档中那样使用各种Material，但是它们都不给我默认对象材质的结果

我通过为材料添加child.material来解决它，所以这是答案

loader.load( 'obj/male02/male02.obj', 'obj/male02/male02_dds.mtl', function ( object ) {

                    object.traverse( function ( child ) {

                    if ( child instanceof THREE.Mesh )
                    {
                    //child.geometry.computeFaceNormals();
                    var  geometry = child.geometry;
                    //console.log(geometry);
                    //geometry.dynamic = true;
                    material = child.material;
                     mesh = new THREE.Mesh(geometry, material);
                        scene.add(mesh);

                    var useWireFrame = true;
                        if (useWireFrame) {
                            mesh.traverse(function (child) {
                                if (child instanceof THREE.Mesh) 
                                {
                                child.material.wireframe = true;
                                child.material.color = new THREE.Color( 0x6893DE  );
                                }
                            });
                        }

                    }

                    object.position.y = - 80;
                    //scene.add( object );

                    });

在这里我添加了material = child.material; 就像geometry = child.geometry; 而且效果很好
