Hi @wangdongw, unfortunately it is not immediately possible for me to provide the compiled module.
You can try to compile by following the below steps:
Pybind11, OpenMP, Eigen, Open3D
)cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build/
. This will generate the .so
file.graph_filter
moduleHope this helps. Feel free to re-open if you face any problem.
Thank you very much and I will try it again.

Hi @wangdongw, unfortunately it is not immediately possible for me to provide the compiled module.
You can try to compile by following the below steps:
Install the dependencies (Pybind11, OpenMP, Eigen, Open3D)
Modify the path on line 19 in CMakeLists.txt to point to the install directory of Open3D
Generate build files using cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
Compile using cmake --build build/. This will generate the .so file.
You can now copy this file to your project directory and import the graph_filter module
Hope this helps. Feel free to re-open if you face any problem.

Dear pmkalshett, my system is Windows, and I want to konw if I can use the CMake and VS2015 software to generate the python module ? I have try it the whole day, but not successful.

Yes it should be possible. Are you getting an error during compilation?
Yes,especially during the compilation process of Open3D.

Is the error during installation of Open3D or while compiling the current project?
The Open3d install successful by Cmake, but the VS2015 can not bulid successful. When compiling the current project, the path of open3d cannot be searched.

The CMakeLists.txt would need to be modified to be able to use in Windows. Unfortunately, I do not have a Windows machine to test this. You can try adapting the current CMakeLists.txt using https://github.com/intel-isl/open3d-cmake-find-package/blob/master/CMakeLists.txt.

I installed the ununtu system, but it always shows that the Open3D library cannot be found when cmake, as shown in the attached picture. Can you help me?------------------ 原始邮件 ------------------

I don't see any attached image on the Github web interface at https://github.com/pmkalshetti/fast_point_cloud_sampling/issues/1
I installed the Open3D by Anaconda command : conda install open3D.
The results of Cmake are following: -- Found pybind11: /home/wangdongw/anaconda3/include (found version "2.6.1" ) -- Could NOT find Open3D (missing: Open3D_DIR) -- Configuring done -- Generating done -- Build files have been written to: /home/wangdongw/test_my/fast_point_cloud_sampling
The Open3D can not be found, even if I have modified the path on line 19 in CMakeLists.txt to point to the install directory of Open3D.

Perhaps you can provide the version and installation method of the dependent library, the error may be related to this, thank you.

Is Open3D used as a C++ library or a python library in this project?

Open3D is used as a C++ library as well as a python library. The way to install Open3D would be to compile its source code and also generate its python bindings, instead of using conda install.
I have compiled open3D, and I can find the path of open3d in cmake, but it still prompts that Open3D.h cannot be found.

add this line in the front of wrapper.cpp:
#include <pybind11/eigen.h>
I am not familiar with using pybind11 to compile python modules. Can you provide compiled python modules? Thank you very much for your help.
