I am a beginner for OpeGL ES.when I read the OpenGL ES 2.0 programming guide, it says in chapter 12,"Framebuffer Object",that if the image will not be used as a texture,using a renderbuffer may have a performance advantage.Then I try to render to image, but after
a few failures, I still do not konw how to implemente it. Is anybody here can help me here?
many thanks!!
