Existing context

OOGL is as modular as possible and it even allows you to use another library to create a window and OpenGL context. The process for this is described in this article.

Using a context created by another library

If another library has a certain context creation option OOGL doesn't have yet, but would still like to use the OpenGL wrapper functions, you can tell OOGL to work with a pre-existent context.

After you've created and activated a compatible OpenGL context (3.2+ core), you can instantiate a Context class to manage it by calling:

GL::Context gl = GL::Context::UseExistingContext();

After that, all wrapper functions can be used as usual. The class will still load its own set of extensions by calling LoadExtensions in Extensions.hpp, but other than that nothing is created or destroyed.
