Why are you speculating about it instead of just reading the extension? https://www.khronos.org/registry/OpenGL/extensions/INTEL/INTEL_map_texture.txt This extension allows to create textures with 'linear' layout which allows for simplified access on user side (potentially sacrificing some performance during texture sampling). _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
