Dec 25, 2015 at 0:15 comment added Nathan Reed @joojaa Yes that's basically the point the paper is making: alpha can represent either opacity, coverage, or a combination of both. :)
Dec 24, 2015 at 22:06 comment added joojaa @NathanReed Will look thnx, but here it is simply that even if alpha worked right coverage wont know which parts cover the pixels and which not. So Two layers with 50% alpha could mean fully opaque or only one layer visible because objects fill identical region we just dont know.
