Presentation
OpenGL Mathematics (GLM) is a mathematics library for 3D applications based on OpenGL Shading Language(GLSL).
The project's goal is to provide to 3D programmer the same tools when he develops under GPU and CPU. This project wasn't limited by GLSL tools, an extension system based on GLSL extensions development conventions allows to extend GLSL capabilities.
GLM is release under MIT license and available for all version of GCC from version 3.4 and Visual Studio from version 7.1 (2003).
You can checkout SVN development sources from https://glf.svn.sourceforge.net/svnroot/glf.

04/27/2008 : 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".

01/26/2007 : Cattmull Clark subdivision sample
A new sample is available. It's an update of Philip Rideout's Catmull Clark subdivision program that uses GLM. Released with pleasant permission of Philip Rideout.

01/06/2007 : GLM 0.5.0 released
This release include GLSL 1.2 new feature in the core implementation. Also, it includes swizzle read and write operators and a custom options system to setup GLM.
It includes some new extensions to extend GLSL features but they remain experimental. The next release should provide the first stable extensions.
The GLM 0.5.0 packages contain some basic samples and some documentation. The ray tracer sample has been updated to GLM 0.5.0. Except for specific cases, especially with extensions, GLM 0.5 is backward compatible.
Now, GLM development is taking advantages of SourceForge.net services: a bug tracker system and the development source code is publicly available on SF.net SVN server.

05/22/2006 : GLM 0.4.1 released
A GLM update is available. It simply includes some examples for a sweet start with GLM.
The examples show how to use GLM with OpenGL intermediate mode and OpenGL vertex arrays. Also, they show how to use GLM extensions to replace GLU and OpenGL function witch could slightly increase performances by decreasing the number of OpenGL states changes.

05/17/2006 : GLM 0.4.0 released
This release introduces first GLSL 1.2 features as planed. Also, various new extensions have been added and updated. Finally, it's not anymore required to include windows.h before glm.h when windows.h is required.
The number of features of GLM, including extensions, start to really increase the compilation time. That's why it's recommended to use precompiled headers.

04/23/2006 : 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;).
04/22/2006 : GLM 0.3.2 released
This release corrects two main bugs. First, a bug of the imat4 and mat4 division operators and other correct the vectors components access from texture coordinate way.

03/28/2006 : GLM 0.3.1 released
This update adds GCC 4.0 support for MacOS X and Linux and GCC 4.1 under Linux. Also, its provides some optimisations.
Further release will prodive GLSL 1.2 compliances.

02/19/2006 : GLM 0.3 released
A new release of GLM is now available. It improves GLSL data type conversion and construction compliance. Also, It's adds extensions like some to manage double-precision and half-precision float numbers. Finally a Doxygen documentation has been added.
This new release have been tested under Visual C++ 7.1, Visual C++ 8.0, GCC 3.2.3 et GCC 3.4.2.

05/06/2005 : GLM 0.2 released
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.
05/04/2005 : English pages
The english section of this site is now available.
02/21/2005 : 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.
