The project uses the following 3rd party libraries:

- `Open3d` for 3D point cloud processing (as binary submodule for win64 that we store in [submodule-open3d](https://github.com/diffCheckOrg/submodule-open3d)). Note that we deactivate the visualization part of `Open3d` to avoid conflicts with our visualizator.

- `Open3d 0.18.0` for 3D point cloud processing it needs to be installed from source [from here](https://github.com/isl-org/Open3D/releases/download/v0.18.0/open3d-devel-windows-amd64-0.18.0.zip), unzip the file and by following the instructions below:

- `Eigen` for linear algebra (needed by `Open3d`)

- `fmt` for string formatting (needed by `Open3d`)

- `libigl` mainly for I/O and visualization
