Personally I would take one of mature C++ engines and wrap it
you like
with Objective-C (using Objective-C++). I generally shy away from
recreating something if I don't really need to do that.
How about writing a wrapper for this one:
http://quesa.sourceforge.net/
it is Apple related of some sort, it's an free implementation of
QuickDraw™ 3D (QD3D), released under BSD License (so no trouble
here) and quite mature.
QD3D is a pretty old API. (Introduced 1995, discontinued 1998.)
I'm not sure how well the Quesa implementation supports features
like textures and lighting, and I'd be very surprised if it had
any support at all for newer stuff like shaders. Depending on what
you're doing, this'll probably be somewhere between a mild
annoyance and a total showstopper.
How about checking that out instead of spreading wild speculations?
Maybe the following is a good starting point:
http://quesa.sourceforge.net/developer/apiref/MasterTOC.html
and there I see at least QuesaLight.h and QuesaShader.h which seem
to deliver what you're asking for.
By "shader" I'm referring to vertex and pixel shader programs, not
illumination shader models (like Gourad and Phong shading). The
texturing support also looks a bit limited compared to what's
available in modern APIs such as OpenGL._______________________________________________
