}

Currently we have only tested our code on 64-bit windows systems and Visual Studio 2022 Professional.

Dependence

  • CGAL
  • Eigen3
  • Boost
  • Libigl

Please using vcpkg to install dependent libraries!!!

Important: Please use "git clone" to install vcpkg, otherwise you may get errors in cgal installation.

  • .\vcpkg install boost:x64-windows

  • .\vcpkg install cgal:x64-windows

    ​ use "git pull" if you get errors with the "gmp" library.

  • .\vcpkg install Eigen3:x64-windows

  • .\vcpkg install libigl:x64-windows

  • .\vcpkg integrate install

MSVC on Windows

Download this project: CWF

Open Cmake-GUI

Where is the source code: CWF

Where to build the binaries: CFW/build

note: check the location of dependencies and install. It is recommended to use vcpkg to add dependencies.

Configure->Generate->Open Project

Then, build the project:

ALL_BUILD -> Build Turn Debug to Release -> ALL_BUILD -> Build

Test

The example is in 'MAIN'.

All the files is in 'CWF\data'.

The output files is in 'CWF\data\LBFGSOUT'.

We put the result of our operation in 'CWF\data\LBFGSOUT\DemoOutput', you can use it for comparison to know whether the program is running correctly.

IMPORTANT NOTE:

Make sure you are using C++ 14, not C++ 17 or newer versions.

This code is not optimized for speed, but for clarity.

The default number of Openmp parallel threads is 30, set according to an AMD Ryzen 5950x CPU, please set different number of threads according to the CPU you use to get the best running effect.

Testing Platform

  • Windows 10
  • Visual Studio 2022 Professional
  • AMD Ryzen 5950X
  • 64GB Memory

Considering that most computers may not have this configuration, this commit does not support acceleration.

In order to allow you to view the optimization process in more detail, we have only set the optimization stop at 50 iterations, you can manually stop the optimization, and view all iteration results in the data\LBFGSOUT folder.
