好的，终于找到解决方法了！
我为画布交换纹理的方式是错误的，我认为这是一个错误。
我在psychok7 找到了关于这个答案的线索。
好吧，我没有加载然后更改纹理……我更改了 ColladaLoader.js 文件中的代码。嗯，几乎一样。由于我使用“加载”，我在加载函数中添加了几次 imageReload，并且在调用“解析”函数时。然后，在解析函数中，我也做了一些更改，因为给出的代码在他们的链接上是错误的。
对于那些感兴趣的人，一份更改列表和我的最终代码。遗憾的是，我无法实现“相同”的功能（发送一组纹理，执行 regExp 的操作，并一次替换多个纹理），这部分对我来说是错误的，因为我只需要更改一个纹理文件......
- 我不做 iamge.init_from = iR.new_image;在 regExp 循环的东西中……而是添加 image.init_from = iR;就在正则表达式之前。
- 在我的文件中调用函数时，我发送了一个数组……它没有记录，没有示例，并且很难理解它。好吧，不要尝试直接发送 .png 或 .jpeg url，将这些名称放在一个表中，然后放在调用该数组的函数中。不要忘记删除路径，因为它应该与您的 collada 文件中描述的路径相同（所以在我的例子中，只是纹理名称，因为我的 collada 文件与纹理共享相同的文件夹）。
- 在psychok的代码中，“parseLib”调用中显然存在错误，他在其中编写了类似parseLib(“//dae:library_materials/dae:material”, Material, “material”);而不是 parseLib("library_materials material", Material, "material"); （这是有效的，并且是原始代码）。
所以，长话短说，这是我调用 collada 的代码
loader = new THREE.ColladaLoader();
newtextures = ['dokMixer.png'];
loader.load('models/collada/7cm.005.dae', newtextures,function colladaReady( collada ){
player = collada.scene;
skin = collada.skins [ 0 ];
player.scale.x = player.scale.y = player.scale.z = 0.10;
//i'll add code here later for extra bump mapping on webgl versions
//usefull for shadows on webgl version
daemesh = player.children[0];
daemesh.castShadow = true;
daemesh.receiveShadow = true;
scene.add( player );
});
这是 colladaLoader 中的代码。它是函数加载和解析的替代品。
