OpenGL ES on QUALCOMM BREW
Posted at July 20, 2005 08:16 AM in BREW
GameDev.net brings us an introduction to OpenGL ES on BREW. It also goes into some introductions on BREW which can be helpful to some people.
At last we come to the actual topic of this article, OpenGL ES. It taken a while to get here mainly because for a lot of people this will be their first non-PC programming target.
If you have any experience with writing Open GL code you will find your knowledge translates nearly directly to GL ES. There are however a few differences. The startup and shutdown sequence is different from PC based Open GL. Given that there are no floating point functions things have slightly different names. Most of the names simply replace the trailing f (for float), with an x (for fixed). The most significant difference is GL ES does away with the immediate mode glVertexf interface. All renderering is done through the batched glDrawElements interface for improved efficiency.
For anyone looking for a quick start into 3D development on BREW, this article will help out. Although the concepts are game driven, then can apply to any sort of 3D application.
