Question

HY！我正在使用三个j（webgl）。我试图嵌入html网页，但不知怎的，它不想工作。我正在检查的教程： http://learningthreejs.com/blog/2013/04/30/closing-the-gap-between-html-and-webgl/ http://stemkoski.github.io/Three.js/CSS3D.html

stemkoski正在使用三个js v58，也是v60。但它真的不想使用v68（最新版本）。我没有收到任何错误消息，只是网站应该是黑屏。

我也可以做类似http://threejs.org/examples/#css3d_youtube的事情。

我的问题是有解决方法，还是＆＃34; hotfix＆＃34;对于这个问题，因为我没有想法。

感谢您的回答。

然后让我们说我使用这段代码：

正如我上面提到的，这是来自http://stemkoski.github.io/Three.js/CSS3D.html的代码，他从另一个教程中创建了他的代码：http://learningthreejs.com/blog/2013/04/30/closing-the-gap-between-html-and-webgl/这个代码。

问题是，theese正在制作三个js r58-r60（让我们说这是旧代码）。我想用三个js r68（最新版本）做同样的事情。但不知何故，当我在r68上启动相同的代码时，屏幕变黑而不是显示html页面。这是一个已知错误，您可以在此处查看http://learningthreejs.com/blog/2013/04/30/closing-the-gap-between-html-and-webgl/：

你好Jerome，谢谢你的兴趣。这里有几个jsfiddles   从stemkoski的github复制，显示了三个r58和   R68。观察到样本之间的唯一区别是   正在使用的图书馆：Threejs 58（工作） - http://jsfiddle.net/jL48v/2/   Threejs 68（破碎） - http://jsfiddle.net/jL48v/3/

我已经尝试了几种方法让这项技术在r68中运行，   但到目前为止没有太多运气。

刚才意识到我搞砸了依赖加载顺序。这是一个   ＆＃34;固定＆＃34;破坏版的r68 - http://jsfiddle.net/jL48v/4/

但他/她忘了写解决方案。而且v4也没有工作。

三个js嵌入了html
