一、相关环境
系统： windows10
CMake: 3.21.4
Visual Studio: 2019
Open3D: 0.12.0
二、源码编译
2.1 下载源码
git clone --recursive https://github.com/intel-isl/Open3D
如果网上太慢，可以采用加速接口
git clone https://github.com.cnpmjs.org/isl-org/Open3D.git
# git clone https://hub.fastgit.org/isl-org/Open3D.git
# git clone https://github.91chi.fun//https://github.com/isl-org/Open3D.git
2.2 切换到指定分支
下载完后进入Open3D目录，用git tag查看分支，然后切换到指定分支，这里切换至0.12.0
git checkout v0.12.0
2.3 更新第三方库
- 修改
Open3D目录下.gitmodules文件中地址，换成加速地址，如
[submodule "3rdparty/pybind11"]
path = 3rdparty/pybind11
url = https://github.com/pybind/pybind11.git
替换为
[submodule "3rdparty/pybind11"]
path = 3rdparty/pybind11
url = https://github.com.cnpmjs.org/pybind/pybind11.git
- 执行以下命令
git submodule sync
git submodule update --init --recursive
2.4 编译
- 利用CMake，选择资源路径和编译路径，依次点击
Configure和Generate.
- 在生成目录用
Visual Studio 2019打开Open3D.sln工程
在CMakePredefinedTargets目录下选择ALL_BUILD作为启动项，然后选择Release,点击重新生成进行编译。
注意- 编译的时候选择用管理员身份打开VS2019，因为生成目录默认在
C:/Program Files (x86)目录下。如果不用管理员身份打开，在CMake Configure时可以修改安装路径到非系统盘 - 另外我编译过程中出现下载
filament库失败的情况，我是先下载~\Open3D\3rdparty\filament\filament_download.cmake文件中指定的库文件，然后存放至~\Open3D\3rdparty_downloads\filament,并将filament_download.cmake文件中的链接修改为本地保存路径。
- 编译的时候选择用管理员身份打开VS2019，因为生成目录默认在
三、安装
在CMakePredefinedTargets目录下选择INSTALL作为启动项，点击生成。
自动会保存在C:/Program Files (x86)目录下。如果安装成功，该目录下会有bin,CMake,include,lib四个文件夹。
四、测试
参考C++ interface先下载TestVisualizer.cpp和CMakeLists.txt
存放在自定义目录下，然后利用CMake进行Configure和Generate。
我在测试过程中出现了“RuntimeLibrary”的不匹配项: 值“MT_StaticRelease”不匹配值“MD_DynamicRele的问题。MT（多线程静态的版本）和MD（多线程动态的版本）以及MTd, MDd的区别可以参考VS 运行库MT、MD的区别。
解决办法如下：
选择工程，右击属性，依次点击C/C++ ==> 代码生成 ==> 运行库，选择MT。
或者直接在CMakeLists.txt文件中添加
set(CMAKE_CXX_FLAGS_RELEASE "/MT")
set(CMAKE_CXX_FLAGS_DEBUG "/MTd")
编译完成后运行以下命令得到结果：
.\TestVisualizer.exe pointcloud "D:/test.pcd"
