I think no, because it was made for OpenGL 3.

@prsolucoes is correct, OpenGL 3.x or 4.x are required. There was some work for GLES put forward a while ago, but that is now stale. Supporting OpenGL 2.x is technically possible, but would require significant effort to implement.

Does nanogui call OpenGL 3.x directly? Doesn't it make the calls indirectly through nanovg? If that's the case, I read that nanovg has several backends, and not only OpenGL 3.x... it seems 2.x is also supported, and even some ES versions...

Yes, see glutil.cpp (specifically e.g., renderbuffer stuff).

I know that the future version of NanoGUI (which is not fully released yet) has GLES support, but that will not be back-ported here. In the interim, I suggest you make a fork of NanoGUI and change / remove things as needed. If you are successful, I'm sure others would be grateful to you for sharing (e.g., share a link here).

As far as I understand it, this repository will never have GLES support at this point (since it is already solved in the future version).
