-# Star-UnstructuredVolumetricMesh
-
-Star-UVM is a C library whose goal is to manage unstructured volumetric meshes
-defined by a soup of tetrahedra. Once spatially partitioned, the user can
-efficiently identify tetrahedra cut by an axis aligned box or access the
-specific tetrahedron that encompasses a given position.
-
-Only geometric data is processed by Star-UVM. No assumption is made on their
-associated properties. Either way, Star-UVM provides data, such as primitive
-indices and barycentric coordinates, needed to retrieve the properties attached
-to each tetrahedron. These properties can thus be managed externally without
-arbitrary constraints imposed by Star-UVM on their size, alignment or type.
-
-## How to build
-
-Star-UVM relies on the [CMake](http://www.cmake.org) and the
-[RCMake](https://gitlab.com/vaplv/rcmake/) packages to build. It also depends
-on the [RSys](https://gitlab.com/vaplv/rsys/) and
-[Embree](https://embree.github.io/) libraries. It is compatible
-GNU/Linux on x86-64 architectures.
-
-First ensure that CMake is installed on your system. Then install the RCMake
-package as well as the aforementioned prerequisites. Finally generate the
-project from the `cmake/CMakeLists.txt` file by appending to the
-`CMAKE_PREFIX_PATH` variable the install directories of its dependencies. The
-resulting project can be edited, built, tested and installed as any CMake
-project. Refer to the [CMake](https://cmake.org/documentation) for further
-informations on CMake.

+
+## Requirements
+
+- C compiler (C99)
+- POSIX make
+- pkg-config
+- [Embree](https://github.com/embree/embree)
+- [RSys](https://gitlab.com/vaplv/rsys)
+- [Star-Mesh](https://gitlab.com/meso-star/star-mesh) (optional)
+
+## Installation
+
+Edit config.mk as needed, then run:
+
+ make clean install
## Release notes
+### Version 0.3
+
+- Replace CMake by Makefile as build system.
+- Update compiler and linker flags to increase the security and
+ robustness of generated binaries.
+- Provide a pkg-config file to link the library as an external
+ dependency.
+- Fix compilation warnings.
+
### Version 0.2
-Update of the acceleration data structure backend from Embree3 to Embree4
+Update of the acceleration data structure backend from Embree3 to
+Embree4
### Version 0.1
-- Add the `suvm_mesh_desc_compute_hash` function which uses sha256 encryption
- to calculate a digest from the mesh data.
-- Add the `suvm_get_mesh_desc` function that returns the mesh data, i.e. the
- list of node positions and the list of cell indexes.

+- Add the `suvm_get_mesh_desc` function that returns the mesh data, i.e.
+ the list of node positions and the list of cell indexes.
- Replace the obsolete Star-Tetrahedra dependency with Star-Mesh.
- Work around a numerical inaccuracy of barycentric coordinates.
- Fix warnings detected by gcc 11.
