OpenGL Mathematics
GLSL + Optional features = OpenGL Mathematics (GLM).
A C++ mathematics library for 3D graphics.


- OpenGL Mathematics (GLM) is a C++ mathematics library for 3D software based on the OpenGL Shading Language (GLSL) specification. -

- The goal of the project is to provide to 3D programmers math classes and functions that miss in C++ when we use to program with GLSL or any high level GPU language. With GLM, the idea is to have a library that works the same way that GLSL which imply a strict following of GLSL specification for the implementation. -

- However, this project isn't limited by GLSL features. An extension system allows to extend GLSL capabilities. It allows GLM to be a great subtitute for some OpenGL 3 deprecated functions, to work following a clean programmable approach. -

- GLM is release under MIT license and available for all version of GCC from version 3.4 and Visual Studio from version 8.0 as a platform independent library. -

GLM 0.9.0.0 released
- GLM 0.9.0.0 is finally available! It brings various API changes from GLM 0.8.4.X branch which makes it not backward compatible. - GLM is now compatible with Objective C++ to be used for MacOS X and iPhone projects. -

- To continue making GLM a better library, 2 mailing lists have been created for users and developers. -

GLM 0.9 Beta 2 released
- GLM 0.9 Beta 2 is available and should be the last development release of GLM 0.9. -

- The code has been moved from a SVN to Git repository which branching efficiency allowed to remove all the experimental code from this release. -

- Various bug fixes and manual updates have been done too. -

03/04/2010
GLM 0.9 Beta 1 released
- A new development version of GLM 0.9 is available. -

- This version is based on GLSL 4.0 and supports the new common and integer functions. - Also a long and frequently asked feature has been implemented: inplicit conversions. - However, the rules defining implicit conversions by GLSL 4.0 are quite weaked and can't really be apply in C++. -

- Reaching the beta status, this new features close the feature list of GLM 0.9. - Further development releases may happen before the final release. -

09/02/2010
GLM 0.9 Alpha 1 released
- First step until a major release for GLM with this first alpha of GLM 0.9. -

- This version brings a large internal redesign to improve the library reliability and optimized some parts. - It removed the deprecated features and API which implies that GLM 0.9 isn't backward compatible. -

- For most users the build issues when upgrading to GLM 0.9 should be reduced especially if they follow the deprecation policy. -

- This release is still UNSTABLE and not recommanded for commertial products. -

GLM 0.8.3.0 released
- This version brings to main changed: Stable extensions and a new extension system. -

- The first stable GLM extensions are: GLM_GTC_double_float and GLM_GTC_half_float for higher and lower vectors and matrices floating point precision. GLM_GTC_matrix_operation provides determinant and inverse matrix calculation. GLM_GTC_matrix_transform allows to build scale, rotate and translate matrices and GLM_GTC_matrix_projection provides varius functions to build projection matrices. Few stable extensions yet but the number is going to grow with the next release! -

- Both GLM 0.8.2.x extensions use method are deprecated (but still working) and replace by a new one. If you wnat to use GLM_GTC_half_float just include "glm/gtc/half_float.hpp" and it is going to be included in GLM namespace. -

- Finally, quite some file have been renamed, using "hpp" instead of ".h". Old file have been deprecated but are still available so that GLM 0.8.3.0 is fully compatible with GLM 0.8.2.x. -

GLM 0.8.0 final released
- GLM 0.8.0 is released. This new version is now based on GLSL 1.30 specification which provided new functions and precision qualifiers. -

- Beyond this, lot of changes have been done to make GLM easier to use, easier to develop, more reliable, more conform to C++ ISO98 standard and GLSL specifications. -

- It involves that GLM 0.8.x is not backward compatible with GLM 0.7.x... However, an application port from GLM 0.7.x to GLM 0.8.x isn't a huge work and actually for some, it won’t be work at all. -

- On GLM core side, based on GLSL features, vector types can't be automatically cast to pointer anymore for code safety purposes. Vector constructors require a single scalar parameter of the exact number of components. -

- On GLM extension side, the mechanism to use them has changed. The old [__]***GTX way doesn't exist anymore. Have a look on the manual for more information. -

- Have a look on the manual and the changelog for more information. Don't forget to send your feedback and enjoy! -

GLM 0.8.0 beta 1 released
- GLM have been updated to support GLSL 1.30. API documentation had significant improvements to make easier finding of GLSL functions and types. -

- GLM 0.8.x is NOT backward compatible with GLM 0.7.x. Upgrade to GLM 0.8.x could involve build errors for the following cases: A lot of improvements have been made to increase the conformance with GLSL specification. Lot of GLSL 1.30 features were already exposed in extensions that have been deleted. The extension syntaxe based on ARB convension is no long used. -

- Due to the number of changes GLM 0.8.0 is release as beta first. The final release is schedule for october. -

GLM 0.7.2 released
- GLM 0.7.2 is released. The documentation have been completed again and several issues handle with precompiler options. -

- #define GLM_SWIZZLE GLM_SWIZZLE_FUNC allows to use swizzle operators with internal functions. For example, glm::vec3(1, 2, 3).zyx is replaced by glm::vec3(1, 2, 3)._zyx() with this option. -

- #define GLM_FORCE_NO_HALF allows to include all extensions (#include "glm/glmext.h") without any support of half-precision floating-point numbers. -

- #define GLM_AUTO_CAST GLM_DISABLE allows to disable automatic cast (eg: glLoadMatrixf(glm::mat4(1.0))) which could involve unfortunate issues in some cases. -

- More information on these topic are available in GLM manual section 5 "Known issues". -

Roadmap for the years
- Version 0.4 will complete matrices and vectors operators and will add GLSL 1.2 features. First, conversions simplifications will be integrated. Then, 4 per 3 matrices and outer product will be available from extensions. The transpose function is already available from extension. -

- Version 0.5 will integrate GLSL 1.2 features to GLM core. -

- Version 0.6 will add swizzle operators in reading and writing. (eg: vec3 v1(1.0, 2.0, 3.0); vec3 v2 = v1.xxx; v1.zyx = v;). -

- A new release of GLM is now available. A few bugs have been fixed, the portability of GLSL into C++ has been improved, and new experimental extensions have been implemented, enhancing GLSL features. -

- Project now supports quaternions, adds new features to handle colors, vectors and matrices. For example, GLM allows base colors changing, vector projected operations, and 2D/3D transforms. -

- To demo the features of this new version, a sample program is included. It is a simple Ray Tracer supporting reflected and refracted rays, three lights types (point, directionnal and spot), two objects types (sphere, plan), using all of the GLM possibilities. -

GLM 0.1 is available
- This is the first public availability of GLM. This library supports part of GLSL specifications : All vectors and matrices types, and all the operators and associated functions. -

- For now, there isn't detailed documentation, but you can freely have a look on GLSL specifications. Consider any incoherence with GLM as an error. Keep in mind the library is included in the namespace "glm". -

- This project is multi platform and was successfully tested under Visual C++ 7.1, MinGW 3.4 and GCC 3.4. -
