Hi Kelvin, Do you mind sharing the code you’re using? I’m looking back at some code I wrote a while back to learn OpenGL and I see that the implementation was pretty straightforward.
The OpenGL.GL module already provides the implementations for runtime functions such as glEnable, glBlendFunc and glClearColor. In my code I just import that and use those functions the same way you use any other function.
