Porting C++ OpenGL Game to iPad

Question

We have a game, developed in C++ and OpenGL for Windows and Mac.

Now we want to port the game to iPad. Is there a better way than writing the entire program in Objective-C to make our game work on iPad?

Now I am an iPhone/iPad noob, so pardon if the question is dumb.

Answer 1

You probably need to write only a small part in Obj-C that deals directly with iOS(creating a gl surface, input etc). Rest should work fine. You just need to make sure you will be using only the subset of OpenGL that is in OpenGL ES.
