glReadPixels is one way you have to call something like glDrawBuffer (GL_COLOR_ATTACHMENT0_EXT); when with FBO's I think ( along time since I have done this )

I am currently rendering to a texture by attaching it to a camera as Camera::COLOR_BUFFER. Now I want to read data back to the CPU from this texture. I have looked at the examples and examined the forum, but I still don't understand how to do this. Can anyone please point me to the information I need or provide some code examples to get me started?
