GLSL + Optional features = OpenGL Mathematics (GLM). A C++ mathematics library for 3D graphics. OpenGL Mathematics (GLM) is a header only C++ mathematics library for graphics software based on the OpenGL Shading Language (GLSL) specification. GLM provides classes and functions designed and implemented with the same naming conventions and functionalities than GLSL so that when a programmer knows GLSL, he knows GLM as well which makes it really easy to use. This project isn't limited by GLSL features. An extension system, based on the GLSL extension conventions, provides extended capabilities: matrix transformations, quaternions, half-based types, random numbers, etc... This library works perfectly with OpenGL but it also ensures interoperability with other third party libraries and SDKs. It is a good candidate for software rendering (Raytracing / Rasterisation), image processing, physic simulations and any context that requires a simple and convenient mathematics library. The source code is under the MIT license. Thanks for contributing to the project by submitting tickets for bug reports and feature requests. (SF.net account required). Any feedback is welcome at glm@g-truc.net. GLM is written as a platform independent library with no dependence and officially supports the following compilers: GCC 3.4 and higher LLVM 2.3 through GCC 4.2 front-end and higher Visual C++ 2005 and higher Any C++ compiler following C++98 norm _________________ _________________ Copyright © 2005 - 2011G-Truc Creation
