I am trying to combine the String Augmented Reality Framework with cocos as the 3d renderer. In the setup I need to provide String with the OpenGL context and the framebuffer.
 stringOGL = [[StringOGL alloc] initWithDelegate: self context: myEAGLContext frameBuffer: myFrameBuffer leftHanded: NO]; 
I get the context like this:
 [[[CCDirector sharedDirector] openGLView] context] 
But how to get the frameBuffer?
