This code implements our volume meshing algorithm described in "Convex Polyhedral Meshing for Robust Solid Modeling" by Lorenzo Diazzi and Marco Attene (ACM Trans Graphics Vol 40, N. 6, Procs of SIGGRAPH Asia 2021). Please refer to our paper for details. You may download a copy here: http://arxiv.org/abs/2109.14434

git clone https://github.com/MarcoAttene/VolumeMesher
On Windows MSVC you may run GRSI_script.bat to automatically configure, compile and run the executable on two example models.
On other systems you may build the executable as follows:
mkdir build
cd build
cmake ..
This will produce an appropriate building configuration for your system. On Windows MSVC, this will produce a mesh_generator.sln file. On Linux/MacOS, this will produce a Makefile. Use it as usual to compile mesh_generator.
When compiled, the code generates an executable called mesh_generator.
Launch it with no command line parameters to have a list of supported options.
Examples:
mesh_generator model.off
creates a file called volume.msh representing the volume mesh enclosed by the input.
mesh_generator -v model.off
same as above, but the -v option makes the tool print useful information during the process.
mesh_generator -v -t model.off
same as above, but -t makes the tool tetrahedrize all the cells before saving.
mesh_generator -s model.off
creates a file called skin.off representing the surface that bounds the volume mesh. skin.off is a mesh of convex polygons.
mesh_generator -s -t model.off
same as above, but -t makes the tool triangulate all the facets before saving.
mesh_generator -b model.off
creates a file called black_faces.off representing the input model with intersections resolved.
We tested our code on MacOS (GCC-10) and Windows (MSVC 2019). It should work on Linux-GCC and MacOS-Clang too, but we have not tested it on these configurations.
