Hi Brian, You marked off ARB_copy_image (and ARB_clear_texture) as in-progress by VMware some months ago -- has there been any movement on that? It appears that Bioshock Infinite requires ARB_copy_image so might be nice to get that added in.
The complication in implementing ARB_copy_image was that st/mesa will pick potentially different PIPE_FORMAT enums for the same internal format, depending on the parameters to the glTexImage call. A developer (irc handle Leftmost, I forget his real name, sorry) tried to wrestle with the issues this presents, but as I recall ended up coming up short. The final implementation probably needs some combination of resource_copy_region and blit. I think resource_copy_region currently is spec'd to require identical formats in src and dst, but that could be relaxed. Anyways, would be interested in hearing whether you guys have made any progress, or if you had thoughts on proper implementation. Cheers, -ilia _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
