Superscape On Making 3D-Accelerated Mobile Games

David Britten, vice president of technology at mobile developer/publisher Superscape, pointed out in his case study of the company’s development of a 3D-accelerated version of its Ducati 3D Extreme game, the consistency of hardware remains a problem. Some devices still don’t support OpenGL ES, while other cause problems because hardware manufacturers don’t always ship product with standardized firmware. The 3D-accelerated version of Ducati 3D Extreme was written using the OpenGL ES Common Lite v1.0 API, the game work was split with the CPU dealing with the gameplay logic, the DSP4 running the geometry, lighting and audio, while the dedicated 3D hardware did the rasterizing and Z buffering.

Tutorial from dmedia: Text Rendering with OpenGL
Category: Developers •
Jun 27, 2007
This tutorial focuses on fairly advanced text rendering. If you’d like to add some text to your OpenGL applications, this is just the right place to be. If you’re using Direct3D, PixelToaster, SDL or whatever else, don’t leave too soon - the techniques presented here may as well work with other pixel plotting libraries. You only need some basic blending and texturing. Some people might think that text rendering is trivial, but in this tutorial we’re going to see that in order to support a nice set of features, such as Unicode compliance, antialiasing or kerning, we’re going to need more than just a bit of coding. Check out the tutorial now.
