Threaded rendering with NSOpenGLView

Question

Hello,

I have an old AGL-based OpenGL windowing system that I am updating to use NSOpenGLView. The engine using it needs to run in its own loop in a separate thread and I am having trouble getting that to work. With AGL, I created the context in the loop thread, so there was no issue, but I'm a little bit confused about the way to do that with NSOpenGLView. I'd like to be able to instantiate it in the nib, so I don't want to create the whole thing in the loop thread. Is it even possible otherwise?

Hope it makes sense.

Your separate thread can attach the NSOpenGLContext it creates to an existing NSOpenGLView by using the setOpenGLContext: method.
