This sample demonstrates how to create an OpenGL ES 1.1 and 2.0 compatible project. When running on PowerVR MBX platforms (e.g., iPod Touch, 1st generation iPhone, iPhone 3G), the sample draws using OpenGL ES 1.1 when running on PowerVR SGX platforms (e.g., iPhone 3GS), the sample draws using OpenGL ES 2.0.-This sample demonstrates how to create an OpenGL ES 1.1 and 2.0 compatible project.
