GLM 0.9.3.0 is finally released. Since the branch 0.9.2, the test bench and the Doxygen API documentation has been expend.

Swizzle operators are a challenging task to implement but thanks to the effort of many contributors, GLM 0.9.3.0 provides finally something interesting even if
not perfect but still a great improvement considering the incompatibilities with some external libraries. GLM 0.9.3 provides two implemetanations, one for C++ 98
compilers and one for C++ 11 compilers providing an implemetnation closer to what GLSL does. Indeed the C++ 98 implementation is compatible with C++ 11 compilers.

GLM 0.9.3.0 is finally released. Since the branch 0.9.2, the test bench and the Doxygen API documentation has been expended significantly leading to an even more reliable implementation and hopefully an even smoother development experience.

From the many improvements, it is worth to acknowledge the addition of the core noise functions as defined by GLSL. The implementation is based on the promoted GLM_GTC_noise features which implement a perlin noise, periodic perlin noise and a simplex noise. The random number generation functions (GLM_GTC_random) which provides various interesting distributions as illustrated below. Reaching GLM tool box, the new experimental extension GLM_GTX_constants provides a set of constant.

=======
For the feature set, the GLSL noise functions have been implemented and based on the implementation of <linkhref="https://github.com/ashima/webgl-noise">webgl-noise</link>.
Some users might prefer the promoted GLM_GTC_noise extension also based on <linkhref="https://github.com/ashima/webgl-noise">webgl-noise</link> but different interface and three noise methods: Perlin noise, periodic noise and simplex noise.
