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 <link href="https://github.com/ashima/webgl-noise">webgl-noise</link>.

Some users might prefer the promoted GLM_GTC_noise extension also based on <link href="https://github.com/ashima/webgl-noise">webgl-noise</link> but different interface and three noise methods: Perlin noise, periodic noise and simplex noise.
