I development C++ (planned fully C++14, C++17 compatible, with Visual Studio support) wrapper for OpenGL API.
https://github.com/AwokenGraphics/diamond-gl

Advantages:
- Support of GLM
- Support of STL (vector, string)
- Utils for simpler access
- Same paradigm as in OpenGL (nearest as can)
- Object oriented for C++
- Combined most OpenGL functions
- Support of DSA

Disadvantages:
- Not all API functions released at now (in TODO - FBO, query, state functions)
- No CUDA support
- In early stage of development
