VS2010下配置OpenMesh

1. 从www.openmesh.org下载最新版的安装包或者源代码，注意下载与自己系统匹配的版本，我下的是VS2010预编译版的，下载源码自己编译是一样的。安装好Visual Studio。

2. 安装OpenMesh，预编译版的是一个安装包，直接打开下一步安装就行。

3. 配置VS，以VS2010为例，打开 项目 —> 项目属性 —> 配置属性 —> VC++目录，在包含目录和库目录中依次添加 C:Program Files (x86)OpenMesh 3.2include 和 C:Program Files (x86)OpenMesh 3.2lib 目录，具体由自己的OpenMesh安装目录决定。

4. 在 配置属性下，打开 C/C++ —> 预处理器定义，添加_USE_MATH_DEFINES，再打开链接器 —> 输入， 在附加依赖项中输入OpenMeshCored.lib 和 OpenMeshToolsd.lib。

5. 从OpenMesh官网提供的code examples （First Steps-Building a cube） 中拷贝cube的测试代码，如下，放到工程中编译执行即可。

6. 运行后会在当前目录下生成一个 output.off 文件。说明执行成功，用OpenMesh目录下自带的 QTviewer 可以打开生成的off文件。
