a lot of algorithms use these kinds of buffers, how can I generate these buffers?
as: ID image, normal image and get the (u,v) value for texture coordination of the pixel.

any code examples? or articles on implementation of these?

thanks a lot!

Look for examples of deferred shading. I think that's close to what you're looking for. It'll certainly give you the right kind of insight.

P.S. for coords you could output the coordinate values straight to the framebuffer or by placing numbers encoded in the color components of a high res texture. You could use high precision textures and buffers or multiple components.
