Hello,
I have searched about offscreen buffers during the WE (it's a personal project) and I have found a piste about FBO (frame buffer objects).
I have read many tutos (in frencj and english) and I think it could help me. These are principally about texture handing, image saving, but I didn't found some about my purpose : saving the previous image (with depth renderer) and redraw it before drawing the new one.
If you know one tuto or documentation about it, it could help me and save me many time.
Thanks for your help in any case.
