Hi, Some progress on the OpenGL project: _ I read much of the sources around NBOpenGL, the architecture looks nice to me, so will keep it, but am actually considering to strip it to OpenGL ES 2! This is a subset of OpenGL, but is supported on more platforms (Android, iOS, RPi), and will be easier to maintain in the long term. _ A working minimal demo in C (https://drive.google.com/file/d/0B6Y_O5MtrUaEbXFjTGhUcTZwY3M/view?usp=sharing) _ SDL2 gave me some headaches (2~3 seconds to start & open a window, could not properly display the title bar, displays big ugly pixels on retina screen, could not test it in Pharo since it did not find library file). So I tried GLFW and LOVE IT (starts fast, handles the pixel density problem nicely, amazing documentation). I will work to bind it with FFI. _ Anybody else working on porting NBOpenGL? I am rather slow, so if we can sync work would be perfect :)
