Buffers are set up that store up the touch-screen inputs, which are then all processed as each new frame is rendered.

New code was created to cope with the iPhone's unique controls.

This is great for iPhone in that many lights set up by the artists or generated dynamically during gameplay have a very low rendering cost. The code gathers up static and dynamic lights decided upon by the artists and turns them into just one or two lights instead, with directional, ambient or spherical harmonic lights all supported. Josh Adams also described how Unreal Engine lights environments. Where Epic had to make changes was primarily in the Render Hardware Interface (RHI) - the 'thin layer' between the engine's render thread and the host platform's API. Game-makers used to the Unreal Engine editor use the exact same Windows-based toolset when developing for iPhone. The same gameplay, collision, math routines and even file formats are used. The engine itself consists of two million lines of code in a 16MB executable, with 90 per cent of that code being platform-independent, with the other 10 per cent tuned to the hardware it is running on.ДЄlmost all of the core functionality of the engine remains in the iPhone iteration of the tech. Interestingly, during the presentation Adams also revealed a range of unsupported platforms that Epic currently has Unreal Engine 3 working on: Linux, Mac,and NVIDIA Tegra 2 (potentially very interesting if the Nintendo DS 2 rumours turn out to be true).Д¬onverting Epic's middleware to the iPhone was no mean feat. UE3 won't work on older iPod Touches and iPhones as they do not support the programmable pixel shaders that the engine requires, but, as newer, faster devices in the mobile Apple family appear, Epic's engine will obviously scale with them. While much of the presentation concerned how Epic's Windows-based tools interfaced with the Mac-based 'XCode' workflow of the iPhone development kit, Adams also showed a working model of an Unreal Tournament level running on the Apple device, with the developer confirming that the demo refreshed at a rate of 25 to 30 frames per second.ДЄdams described the process of bringing UE3 to iPhone as a fun 'can we do it?' project, based on Open GL ES 2.0, meaning it will only work on the newer Apple devices such as the iPhone 3GS, the iPad, and the third-generation iPod Touch. Epic Games' senior console programmer Josh Adams officially introduced game developers to the new iPhone edition of Unreal Engine 3 at the Game Developers Conference this week.
