The compression ratio is fixed so the only variable is the quality of the image. I did make a naïve compressor for the RGBA UNORM format but I opted for the approach going via DXT3 instead because it looks nicer. I later modified that compressor to work for the half-float formats because we can't use DXT3 there. If we did want to avoid any dependencies and we don't care about the quality then that naïve compressor could still be an viable approach. Here's an example of the quality: http://busydoingnothing.co.uk/doge/ - Neil _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
