问题描述
我正在开发一个管理VRML文件的网络应用程序。我也想让用户看到上传的文件，而无需特定的插件或播放器。 X3DOM允许在大多数浏览器中无需插件即可查看X3D文件，所以我想使用它。
I'm working on a web application that manages VRML files. I also want to let users see the uploaded files, without requiring a specific plug-in or player. X3DOM allows viewing X3D files without plug-ins on most browsers, so I'd like to use it.
A，它可用于X3D文件，而不适用于VRML文件。我需要将VRML文件转换为X3D格式。
Alas, it works on X3D files, and not VRML files. I need to convert VRML files to the X3D format.
X3DOM背后的同一个人发布了一个名为InstantReality的软件包，该软件包具有将VRML转换为X3D的实用程序。但是，我宁愿不使用外部实用程序（甚至不确定我是否可以在商业环境中使用它，我找不到其使用条款），而是从我的应用程序代码中调用转换例程。
The same people behind X3DOM released a package called InstantReality that has a utility that converts VRML to X3D. However, I'd much rather not use an external utility (I'm not even sure I'm allowed to use it on a commercial environment, I couldn't find its terms of use) but call a conversion routine from my application code.
推荐答案
！有一个名为的开源项目，该项目可对3D网格进行各种处理。它还有一个名为 MeshlabServer 。
MeshLab! There's an opensource project called MeshLab that does all sorts of processing on 3D meshes. It also has a command-line tool called MeshlabServer.
运行 meshlabserver.exe -i< wrl文件> -o< x3d文件> 执行转换（非常快）。由于它是开源的，所以我没有任何许可问题。
Running meshlabserver.exe -i <wrl file> -o <x3d file> performs the conversion (very quickly). Since it's open-source, I don't have any licensing issues.
