iPhone Game Programming: CoreAnimation vs. OpenGL ES
I saw an interesting question being asked by an aspiring iPhone game developer, "Should I use CoreAnimation or OpenGL ES?".
Simple answer:
Core Animation is fine for games where performance is not critical, and for new programmers will likely be easy to use, OpenGL is needed for anything else.
Long Answer:
Core Animation utilizes OpenGL ES, it is high level, and in my testing works fine in situations where performance is critical.
