Hi, I'm having a few issues with trying to encapsulate my opengl functions within a class so they now are member functions.I want it to run something like: int main(){ Grid *grid = new Grid(SCREEN_WIDTH, SCREEN_HEIGHT); grid-> init(); grid->createlists(); grid->initSDL(SCREEN_WIDTH,SCREEN_HEIGHT); grid->DrawScene(SCREEN_WIDTH,SCREEN_HEIGHT); } Obviously I can't use GLUT (even if I make member functions static I cant call any other mamber functions frokm the same class) but when I use SDL I have some performance issues , especially when resizing the window , it will take about 2 seconds for the window to appear . I was wondering if there are any issues with Mesa and SDL ? Has anyone used GLFW ? and is that a better alternative to SDL ? Regards

Do you have any code? and i have tryed GLFW and SDL there both the same, well all most.

The only alternative's can be your OS, like Win32 API and DirectImnput.

What do you need?
