I don't mind "as_integer" but I wonder if "as_float" (i.e. the negative), wouldn't be more generic (so it could be used for doubles too [1]). > I wonder if the sampler view and surfaces are always going to be bind > as integer for SCALED types, in which case maybe we can just state > that somewhere and move on. It looks like it. GLSL defines gvec4 texture (gsampler2D sampler, vec2 ...) where g is '', 'i', 'u'. But in section 8.7, "Texture Lookup Functions" of GLSLangSpec.3.30.6.clean.pdf it has a table relating texture internal formats with the vector types, and doesn't allow converting between different type. > I've also shown the clear color code in softpipe where it pick the > correct clear color depending on the surface type. > > I've started hacking on u_blitter and r600g to no avail yet to try > and > get some of the -integer tests passing. Jose [1] although this is academic, given that there doesn't seem to be double sample support. _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
