![glm](doc/logo.png) [OpenGL Mathematics](http://glm.g-truc.net/) (*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](https://www.opengl.org)* 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](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 For more information about *GLM*, please have a look at the [manual](http://glm.g-truc.net/0.9.7/glm-0.9.7.pdf) and the [API reference documentation](http://glm.g-truc.net/0.9.7/api/index.html).
