A new version of GLI is available. It provides a better API which is not backward compatible with GLI 0.1.x.x but which makes more sens hopefully.
One important detail is the removal of the Boost dependence but GLM remains required.
The OpenGL 3 Samples Pack will be updated with GLI 0.2.0.0 like all my projects.
GLI is still very experimental and not very advanced in its features but it answers to most of my needs.
