3rd-party iOS SDKs?

My team and I were just starting to get the evaluation version of AirPlay SDK up and running when their pricing structure changed dramatically, along with changing their name to Marmalade. I don't think we can afford them at this time since we just purchased a MacBook Pro and still need to pay for the Apple Developer Program and local business licensing fees.

Can you point me in the direction of any other inexpensive 3rd-party SDKs that might provide similar features? Right now, we don't care so much about compiling for other platforms - I feel like when we are ready for that we will also be ready to license Marmalade or some other SDK. I am aware of GameSalad, but I do come from a programming background and am also aware of 开发者_如何学JAVAcocos2D but was hoping for the option of 3D graphics libraries.

Depending on your 3D requirements, I would recommend cocos2d because there is an additional library in fairly early development called cocos3d, which as you'd expect, adds 3d capability to cocos2d.

May be Shiva3d http://www.stonetrip.com/. Perhaps they will change the price because they cooperated with airplay.
