# Star-CliPpeR
-This library clips triangulated 2D meshes against 2D polygons. Two clipping
-operations between the mesh and the clipping region are provided: the
-subtraction and the intersection. The former removes the clipping region from
-the original mesh while the latter keeps only the mesh part that intersects the
-clipping polygon.
-
-## How to build
-
-The library uses [CMake](http://www.cmake.org) and the
-[RCMake](https://gitlab.com/vaplv/rcmake/#tab-readme) package to build. It also
-depends on the
-[Clipper2](https://github.com/AngusJohnson/Clipper2),
-[Polygon](https://gitlab.Com/vaplv/polygon/#tab-readme) and
-[RSys](https://gitlab.com/vaplv/rsys/#tab-readme) libraries.
-
-First ensure that CMake is installed on your system. Then install the RCMake
-package as well as all the aforementioned prerequisites. Then generate the
-project from the `cmake/CMakeLists.txt` file by appending to the
-`CMAKE_PREFIX_PATH` variable the install directories of its dependencies.
