[Mesa-dev] Question about texture copy with Mesa

[Alexis Hétu]

Hi all,

  I have a small question : I'd like to feed the already rendered result of
my scene (which is "on screen" right now) into a texture sampler for the
rendering of another object. I think this could be achieved by doing
something like glReadPixels and then re-uploading that as a texture, but
this seems very inefficient to me. It there a better way of doing this ? Is
there a proper "MESA" way of doing this ?

Thanks
