OpenGL Mathematics (*GLM*) is a header only C++ mathematics library for graphics software based on the [OpenGL Shading Language (GLSL) specifications](https://www.opengl.org/registry/doc/GLSLangSpec.4.50.diff.pdf).
*GLM* provides classes and functions designed and implemented with the same naming conventions and functionalities than GLSL so that anyone who knows GLSL, can use GLM as well in C++.
This project isn't limited to GLSL features. An extension system, based on the GLSL extension conventions, provides extended capabilities: matrix transformations, quaternions, data packing, random numbers, noise, etc...
This library works perfectly with OpenGL but it also ensures interoperability with other third party libraries and SDK. It is a good candidate for software rendering (raytracing / rasterisation), image processing, physic simulations and any development context that requires a simple and convenient mathematics library.
*GLM* is written in C++98 but can take advantage of C++11 when supported by the compiler. It is a platform independent library with no dependence and it officially supports the following compilers:
- Apple Clang 4.0 and higher
- GCC 4.2 and higher
- Intel C++ Composer XE 2013 and higher
- LLVM 3.0 and higher
- Visual C++ 2010 and higher
- CUDA 4.0 and higher (experimental)
- [Apple Clang 4.0](https://developer.apple.com/library/mac/documentation/CompilerTools/Conceptual/LLVMCompilerOverview/index.html) and higher
- [GCC](http://gcc.gnu.org/) 4.2 and higher
- [Intel C++ Composer](https://software.intel.com/en-us/intel-compilers) XE 2013 and higher
- [LLVM](http://llvm.org/) 3.0 and higher
- [Visual C++](http://www.visualstudio.com/) 2010 and higher
- [CUDA](https://developer.nvidia.com/about-cuda) 4.0 and higher (experimental)
- Any conform C++98 or C++11 compiler
