30/11/2014 - GLM released

GLM is available with many changes.
Transition from degrees to radians compatibility break and GLM help

One of the long term issue with GLM is that some functions were using radians, \ 
functions from GLSL and others were using degrees, functions from GLU or legacy \ 

In GLM 0.9.5, we can use GLM_FORCE_RADIANS to force all GLM functions to adopt \ 
In GLM 0.9.5 in degrees:

    #include <glm/mat4.hpp>
    #include <glm/gtc/matrix_tansform.hpp>
    glm::mat4 my_rotateZ(glm::mat4 const & m, float angleInRadians)
    return glm::rotate(m, glm::degrees(angleInRadians), glm::vec3(0.0, 0.0, 1.0));

In GLM 0.9.5 in radians:

    #include <glm/mat4.hpp>
    #include <glm/gtc/matrix_tansform.hpp>
    glm::mat4 my_rotateZ(glm::mat4 const & m, float angleInRadians)
    return glm::rotate(m, angleInRadians, glm::vec3(0.0, 0.0, 1.0));

In GLM 0.9.6 in radians only:

    #include <glm/mat4.hpp>
    #include <glm/gtc/matrix_tansform.hpp>
    glm::mat4 my_rotateZ(glm::mat4 const & m, float angleInRadians)
    return glm::rotate(m, angleInRadians, glm::vec3(0.0, 0.0, 1.0));

In GLM 0.9.6 if you what to use degrees anyway:

    #include <glm/mat4.hpp>
    #include <glm/gtc/matrix_tansform.hpp>
    glm::mat4 my_rotateZ(glm::mat4 const & m, float angleInDegrees)
    return glm::rotate(m, glm::radians(angleInDegrees), glm::vec3(0.0, 0.0, 1.0));

GLM 0.9.5 will show warning messages at compilation each time a function taking \ 
degrees is used.
GLM: rotate function taking degrees as a parameter is deprecated. #define \ 
GLM_FORCE_RADIANS before including GLM headers to remove this message.

If you are using a version of GLM older than GLM, update to GLM \ 
before transitioning to GLM 0.9.6 to get this help in that process.
Make sure to build and run successfully your application with GLM 0.9.5 with \ 
GLM_FORCE_RADIANS, before transistioning to GLM 0.9.6

Finally, here is a list of all the functions that could use degrees in GLM \ that requires radians in GLM 0.9.6: rotate (matrices and quaternions), \ 
perspective, perspectiveFov, infinitePerspective, tweakedInfinitePerspective, \ 
roll, pitch, yaw, angle, angleAxis, polar, euclidean, rotateNormalizedAxis, \ 
rotateX, rotateY, rotateZ and orientedAngle.
Using GLM template types

There are a lot of reasons for using template types: Writing new template \ 
classes and functions or defining new types. Unfortunately, until GLM 0.9.5, GLM \ 
template types were defined into the detail namespace indicating there are \ 
implementation details that may changed.

With GLM 0.9.6, template types are accessible from the GLM namespace and \ 
guarantee to be stable onward.
Example of template functions, GLM 0.9.5 and 0.9.6 style:

    #include <glm/geometry.hpp>
    #include <glm/exponential.hpp>
    template <typename vecType>
    typename vecType::value_type normalizeDot(vecType const & a, vecType \ 
const & b)
    return glm::dot(a, b) * glm::inversesqrt(glm::dot(a, a) * glm::dot(b, b));
    #include <glm/vec4.hpp>
    int main()
    return normalizeDot(glm::vec4(2.0), glm::vec4(2.0)) > 0.0f ? 0 : 1

Example of template functions, alternative GLM 0.9.6 style:

    #include <glm/geometry.hpp>
    #include <glm/exponential.hpp>
    template <typename T, template <typename, glm::precision> class \ 
    T normalizeDot(vecType<T, P> const & a, vecType<T, P> const \ 
& b)
    return glm::dot(a, b) * glm::inversesqrt(glm::dot(a, a) * glm::dot(b, b));
    #include <glm/vec4.hpp>
    int main()
    return normalizeDot(glm::vec4(2.0), glm::vec4(2.0)) > 0.0f ? 0 : 1

Example of typedefs with GLM 0.9.6:

    #include <cstddef>
    #include <glm/vec4.hpp>
    #include <glm/mat4.hpp>
    typedef glm::tvec4<std::size_t> size4;
    typedef glm::tvec4<long double, glm::highp> ldvec4;
    typedef glm::tmat4x4<long double, glm::highp> ldmat4x4;


With GLM 0.9.5, the library started to tackle the issue of compilation time by \ 
introducing forward declarations through <glm/fwd.hpp> but also by \ 
providing an alternative to the monolithic <glm/glm.hpp> headers with \ 
<glm/vec2.hpp>, <glm/mat3x2.hpp> and <glm/common.hpp>, etc.

With GLM 0.9.6, the library took advantage of dropping old compilers to replace \ 
preprocessor instantiation of the code by template instantiation. The issue of \ 
preprocessor instantiation (among them!) is that all the code is generated even \ 
if it is never used resulting in building and compiling much bigger header \ 

Furthermore, a lot of code optimizations have been done to provide better \ 
performance at run time by leveraging integer bitfield tricks and compiler \ 
intrinsics. The test framework has been extended to include performance tests. \ 
The total code size of the tests is now 50% of the library code which is still \ 
not enough but pretty solid.
Compilers support

GLM 0.9.6 removed support for a lot of old compiler versions. If you are really \ 
insisting in using an older compiler, you are welcome to keep using GLM 0.9.5.

    Supported compilers by GLM 0.9.6:
    Apple Clang 4.0 and higher
    CUDA 4.0 and higher
    GCC 4.4 and higher
    LLVM 3.0 and higher
    Intel C++ Composer XE 2013 and higher
    Visual Studio 2010 and higher
    Any conform C++98 compiler


Finally, GLM is changing Lisence to adopt the Happy Bunny Lisence.
