vs2008和vs2010下配置openmesh

因为要做图形学的实验用到了openmesh，但是网上又没有比较详细的配置和测试方法，摸索完成配置后记下一点笔记。

1.从www.epenmesh.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vs2008预编译版的，下载源码自己编译时一样的。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vs2008为例 打开 工具-》选项-》项目和解决方案-》VC++目录，在包含文件和库文件中依次添加C:\Program Files (x86)\OpenMesh 2.3\include和C:\Program Files (x86)\OpenMesh 2.3\lib目录，具体由自己的openmesh安装目录决定

4在所建工程上右键-》属性-》预处理器-》预处理器定义添加_USE_MATH_DEFINE，同时在连接器-》输入-》附加依赖性中添加OpenMeshCored.lib和OpenMeshToolsd.lib

5从openmesh官网的document中拷贝cube的测试代码，如下，放到工程中编译执行即可，

return 1;
}
}

5.运行后会生成一个.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。
