GLSL + Optional features = OpenGL Mathematics (GLM) A C++ mathematics library for graphics programming 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. GLM is written as a platform independent library with no dependence and officially supports the following compilers: Clang 2.0 and higher CUDA 3.0 and higher 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 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. ### 24/10/2011 - GLM 0.9.2.7 released This revision fixes two problems: First, it adds all matrix products for all possible combinations of none-squared matrices. Thanks to Grant James who has provide the code for that. #include <glm/glm.hpp> void kueken() { glm::mat3x2 m1; glm::mat2x3 n1; ... glm::mat2x2 P = m1 * n1; // Valid before GLM 0.9.2.7 glm::mat3x2 m2; glm::mat4x3 n2; ... glm::mat4x2 P2 = m2 * n2; // Fixed in GLM 0.9.2.7 glm::mat4x3 m3; glm::mat4x4 n3; ... glm::mat4x3 P3 = m3 * n3; // Fixed in GLM 0.9.2.7 ... } This support is actually pretty useful as soon as we are interested in optimizing the matrix storage. It also fixes vector contructors which can take multiple parameters that may be swizzle operands.

Finally, all the Visual C++ /W4 warnings should have been removed. However, for this to happen, it is required to build with the Visual C++ language extension disabled (/Za).

Download: GLM 0.9.2.3 (zip) Download: GLM 0.9.2.3 (7z) Link: Submit a bug report ### 02/06/2011 - GLM 0.9.2.2 released The main improvement of this version comes from the extended number of matrix constructors so that a programmer can used different scalar types for each parameter. #include <glm/glm.hpp> // Create an identity matrix glm::mat3 m( 1, 0.0, 0, 0.0, 1.0, 0.0f, 0, 0.0, 1.0f); The quaternion implementation has been updated as well, fixing the various slerp implementation flavours (mix, shortMix and fastMix) and providing more completeness: Added interaction with GLM_GTX_epsilon and missing lowp_quat, mediump_quat and highp_quat but also none square matrix equivalents. Finally, some efforts have been put to remove warnings across all supported compilers.

By conscequence, GLM_FORCE_CUDA is no longer required to be declared. It fixed a couple of bugs, including Visual C++ supprot when Visual C++ extensions are disabled and fixed implementations of GLM_GTX_vector_angle and GLM_GTX_rotate_vector extensions. Download: GLM 0.9.2.1 (zip) Download: GLM 0.9.2.1 (7z) Link: Submit a bug report ### 09/05/2011 - GLM 0.9.2.0 released GLM 0.9.2.0 provides many exciting features which first of all is the CUDA copiler support so that GLM can be used within a CUDA kernel. This is possible only by defining GLM_FORCE_CUDA before including glm/glm.hpp in the CUDA Kernel source code. New experimental extensions are also available. GLM_GTX_noise is based on the work by Stefan Gustavson and Ashima Arts on WebGL-noise which adds perlin and simplex noise functions in a pure computational way. If everything goes well, this extension will be promoted to GLM core as implementation of the GLSL noise functions. GLM_GTX_ulp provides functions to evaluate the number of ULPs between two floating-point values which gives a way to mesure the accuracy of a function compare to a reference function. In the future, this extension could be used to update the documentation of function and gives the level of accuracy they provide. Finally, GLM_GTX_matrix_interpolation is an extension developed by Ghenadii Ursachi to extract axis and angle of a 4 by 4 matrix but also directly interpolate between two matrices. This extension works only on linear transformed matrices. Last but not least: with the version 0.9.2, GLM supports CTest to manage GLM test suite which makes tests much easier to maintain. The number of tests have significantly increase, even if a lot more tests are necessary. GLM 0.9.2 is not backward compatible with GLM 0.9.1 with only one point: Quaternion SLERP interpolation! In GLM 0.9.1 the function 'mix' always interpolate using the short rotation path but it's no longer the case. The function 'shortMix' has to be called for short path interpolation. 'fastMix' will interpolate two quaternions using a normalized linear quaternion interpolation with non-constant rotation speed.

From GLM 0.9.1 beta, mainly bugs has been fixed. GLM has evolved on many sides since GLM 0.9.0: Improved documentation (manual and doxygen), better test framework, simplified setup/options/configration of GLM and new experimental SIMD API. GLM 0.9.1.0 is not 100% backward compatile with GLM 0.9.0.8 but mainly advanced usages should be affected by the differencies. Have a look at the GLM manual for more information on how to use GLM 0.9.1.

Also, it clarifies that GLM is a header only library when a user try to build it. Once more, there is nothing to build. The development version, GLM 0.9.1 beta, provides an improved API documentation by Alfonse Reinheart, author of a great OpenGL tutorial which uses GLM. This version also improves the SIMD extensions and it fixes many bugs.

All this is described in the largely updated GLM manual. With the new setup system, GLM detects automatically the compiler settings to adapt its implementation to the flag set at build time. It will automatically enable C++0x features, SSE optimizations and the display configuration informations at build-time. The automatic setup can be overdrive by the GLM user. The SIMD API maintly focus on vec4 and mat4 implementations that are embodied by the types simdVec4 and simdMat4. The implemention cover most of the common functions, the geometry functions and the matrix functions as described in the GLSL specifications. Because it is hight inefficient to access individual components of a SIMD register, the simdVec4 doesn't allow it. To reflect this constraint, the simdVec4 has to be converted to vec4 first which would be effectively handle by the compiler thank to the function simdCast. Furthermore, GLM provides some specials functions like simdDot4 that returns a simdVec4 instead of a float with the duplicated dot product value in each components and ensure that no unnecessary component manipulations are performed (typically __m128 to float and float to __m128). This implementation can probably be improve in many ways so don't hesitate to send me some feedbacks. GLM 0.9.1 is not 100% backward compatible with GLM 0.9.0 but mostly advanced usages should be concerned by this compatibility issues.

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.

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_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".

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.

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.

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".

It's an update of Philip Rideout's Catmull Clark subdivision program that uses GLM. Released with pleasant permission of Philip Rideout. Download: CatmullClark sample (zip, 605 KB) ### 06/01/2007 - GLM 0.5.0 released Groove 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.

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.

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. Download: GLM 0.4.0 ### 23/04/2006 - Roadmap for the years Groove 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;). ### 22/04/2006 - GLM 0.3.2 released Groove 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.

Further release will prodive GLSL 1.2 compliances. Download: GLM 0.3.1 ### 19/02/2006 - GLM 0.3 released Groove 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.

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. ### 04/05/2005 - English pages Groove The english section of this site is now available. ### 21/02/2005 - GLM 0.1 is available Groove 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.
