barycuda\n\u003cimg src=\"./docs/barycuda.png\" alt=\"artwork\" width=\"250\"/\u003e\n\nBarycuda is a tiny CUDA accelerated library with no dependencies that\nperforms various barycentric operations. This is an attempt to speed-up\na 3D renderer that I'm working on.\n\nCurrently, the library exposes the following functions:  \n* `point_in_simplex` - takes an array of points, the vertices\nof a 2D/3D simplex, and tells you if each point lies inside the\nsimplex.  \n* `bary_simplex` - takes an array of points, the vertices of\na 2D/3D simplex, and returns the barycentric coordinates for\neach point.\n\n\n## Usage\nYou can use Barycuda directly from C++ (see `src/testBary.cpp` for an example), \nor if you prefer using Python, Barycuda has a Python wrapper available. \nYou can install it by doing  \n\n`pip install pybarycuda`  \n\nInstallation using `pip` will come bundled with a prebuilt\n`libbarycuda.so` for Linux x86-64. The linker paths are correctly set out of\nthe box, and you shouldn't have to change your `LD_LIBRARY_PATH` to be able to\nuse it.\n\n\nI plan to support other architectures in the future, but if you want to\ndo it yourself, you can build the binaries (see below) and add `libbarycuda.so` \nto `LD_LIBRARY_PATH` to make the Python wrapper work.\n\n\nYou will need a CUDA capable system for any of this to work.\n\n## Build\n```bash\n# inside the project directory\nmkdir build\ncd build\ncmake ../\nmake\n```\n\n## Contributing\nFeel free to add more geometric operations related to\ngraphics rendering and raytracing.\n\n## References\nShirley, P.
