Texturing a sphere in iphone's OpenGL ES

Basically i want a 3d rotating earth. gluSphere function isn't found. is it available on开发者_StackOverflow中文版 the iphone's opengl es? how can i render a sphere otherwise?

No GLUT for the iPhone, but this may be what you are looking for

Procedural sphere will not be much helpful when you also want to texture it, I suggest you to use one of the many rendering libraries and a model with proper uv map.
