Hi list, I have two questions: 1. What is holding the release of OpenGLRawGen (see [1]) back? I tried it and it works quite well, although there seems to be a problem with at least some functions: glGenVertexArrays and the related functions are not exported by any core module, although it's part of the core since OpenGL 3.0. I tried to find the source of this error in the code, but the codebase is quite big and I still don't know where things go wrong. 2. Looking at the source of HSOpenGLRaw.c it seems to be quite costly to call OpenGL functions, because every time the function pointer has to be retrieved. Or does GetProcAdress (or the equivalent on Mac and Linux) cache previous results? Other librarys (like GLEW or gl3w for C) load the functions pointers once at initialization (which has of course to be done explicitly unlike in HOpenGL), which I guess is for efficiency reasons.
