I cloned your project on git and would like to say wow! Really good work, I've been working on something similar with both JSC & v8 (JIT, Jailbroken devices only). My question is are you seeing odd depth or CULL issues on the examples, running for example, "lesson4" or "lesson5" results in what appears to be some sort of depth buffer issue or culling issue. I'm very interested in this project and would like to help you out.
If I use this, will my app be rejected from the App Store?
