This article describes the impact of hardware accelerated OpenGL ES (from Imagination Technologies) on the quality and performance of graphics on the Sony Ericsson’s UIQ 3 phones. The obvious gain is in the quality of 3D graphics, including texture filtering, anti-aliasing and faster drawing. The other important gain is in software performance. With hardware accelerated OpenGL ES, the CPU is only running the phone OS and the game logic and not the the rendering. As a result the CPU can spend more time on the gaming experience; developers can implement more complex game play, improve artificial intelligence and use richer audio effects.
