ogre actually doesn't handle input without help,

Ah, yes. I remember we used something extra. OIS, iirc.

My mistake.

this is much how OGRE works, with d3d, opengl, opengl es backends etc,
the usage of an externally created window must be done on a backend
specific basis, and it's opengl backend is capable of that,

Sure. OGRE is a full-fledged 3D engine that also happens to be structured nicely so you can draw into a context provided by something else. :-)

 

 getting gnustep to hand over said window is another task entirely..

Window? Couldn't you get OGRE to just use the 'current OpenGL context' (which would be the platform specific context object that's backing NSOpenGLView's NSOpenGLContext)? 

Does it actually need access to the HWND or its equivalents in other windowing systems?
