macOS配置OpenMesh

安装OpenMesh库

使用Homebrew安装，非常简单，一个命令搞定

1	brew install open-mesh

安装后可能不知道库的具体位置，通过下面命令

1	brew info open-mesh

可以查看库的信息，其中就包括了库的路径，我得到的是

1	/usr/local/Cellar/open-mesh/6.3

用Qt Creator测试OpenMesh

Creator的安装这里不再赘述，新建控制台项目，如test。
在test.pro中添加保护目录和库文件

INCLUDEPATH += /usr/local/Cellar/open-mesh/6.3/include

LIBS += /usr/local/Cellar/open-mesh/6.3/lib/libOpenMeshCore.a
LIBS += /usr/local/Cellar/open-mesh/6.3/lib/libOpenMeshTools.a

main函数中的代码如下：

#include <QCoreApplication>
#include <iostream>
#include <string>
#include <OpenMesh/Core/IO/MeshIO.hh>
#include <OpenMesh/Core/Mesh/PolyMesh_ArrayKernelT.hh>
#include <OpenMesh/Core/IO/reader/OBJReader.hh>
#include <OpenMesh/Core/IO/writer/OBJWriter.hh>

typedef OpenMesh::PolyMesh_ArrayKernelT<> MyMesh;

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    OpenMesh::IO::_OBJReader_();
    OpenMesh::IO::_OBJWriter_();
    MyMesh mesh;
    std::string file = "bunny.obj";
    if (!OpenMesh::IO::read_mesh(mesh, file))
    {
        std::cout << "Failed to read mesh" << std::endl;
        return a.exec();
    }

    if (!OpenMesh::IO::write_mesh(mesh, "out.obj"))
    {
        std::cout << "Failed to save mesh" << std::endl;
        return a.exec();
    }
    return a.exec();
}

程序正确运行。

注意：一开始程序中没加

1 2	#include <OpenMesh/Core/IO/reader/OBJReader.hh> #include <OpenMesh/Core/IO/writer/OBJWriter.hh>

和

1 2	OpenMesh::IO::_OBJReader_(); OpenMesh::IO::_OBJWriter_();

运行时报错[OpenMesh::IO::_IOManager_] No reading modules available!，搜索这里发现需要加上面的内容。

在Cmake中使用OpenMesh

在Cmake中使用OpenMesh，CmakeList.txt如下所示：

cmake_minimum_required(VERSION 3.9)
project(testOpenMeshCMake)

set(SOURCE_FILES main.cpp)

set(CMAKE_CXX_STANDARD 11)

add_executable(testOpenMeshCMake main.cpp)

target_link_libraries (testOpenMeshCMake
        /usr/local/Cellar/open-mesh/6.3/lib/libOpenMeshTools.6.3.dylib
        /usr/local/Cellar/open-mesh/6.3/lib/libOpenMeshCore.6.3.dylib
        )
