What is OpenGL ES?
Khronos Group wrote:"OpenGL ES is a royalty-free, cross-platform API for full-function 2D and 3D graphics on embedded systems - including handheld devices, appliances and vehicles. It is a well-defined subset of desktop OpenGL, creating a flexible and powerful low-level interface between software and graphics acceleration. OpenGL ES includes Common and Common-Lite profiles for floating-point and fixed-point systems and the EGL specification for portably binding to native windowing systems. OpenGL ES 1.1 emphasizes hardware acceleration of the API, while OpenGL ES 1.0 focuses on enabling software-only implementations. OpenGL ES 1.1 is fully backwards compatible with 1.0 - enabling easy porting of applications between the two versions of the API." - Khronos Group
The OpenGL ES specification was developed by the Khronos group and can be viewed here.
What format will the tutorials follow?
Originally the source code produced for the tutorials were made for PocketPC 2003, but were transformed by brendan to the Android Platform. This does not mean that you will not be able to use these tutorials if you are not using PocketPC/Android.
