4K TVs Continue To Rise Despite TV Shipments Dropping
#25
Quote:When you see bumps and pocks in wall paint you are seeing detail meant to be there

You don't notice it. That is the point. With enough visual information, the repetitive information you are seeing creating undesirable effects becomes unnoticeable.

Quote:you aren't seeing rendering artifacts that exist (even at 4K) because there isn't enough resolution in the signal to prevent them from appearing.


4K will still beat, handily, 1080p with any AA you can actually run. In theory you could get some stochastic 32 sample per pixel(with trilinear and max anisotropic that clears 1000 per pixel, algorithm dependent of course. 

Quote:One of the biggest causes of aliasing in modern games is normal mapping and shader operations on textures.


Yes, that is true.

Quote: Increasing the screen resolution does little or nothing to remove them, the way to do that is higher resolution normal maps using lossless compression.


That is entirely backwards actually. Increasing screen resolution is, by orders of magnitude, the best fix. Lower compression actually makes things worse in this particular instance, lower levels of compression offer higher levels of contrast which is where you are going to get your moire from(the type of aliasing your are complaining about). 

Quote:Blur based AA where everything is blurred is crude and undesirable.


This comment is rather comical to me- you see everything in modern games outside of mip 0 is blurred *except the exact objects you are complaining about*. Mip mapping is a straight bicubic downsample blur most of the time, used on all "normal" textures. MSAA is simply doing a Z check and blurring adjacent pixels when the value is offset too much(well, not quite that simple, but that is it in essence). 

Quote:We only want to AA edges and artifacts that require it, not everything.


The only practical way to do that is to increase resolution.

I don't honestly recall how long you have been around, but visual artifacts related to signal theory is a particular area of expertise for me- I publicly and loudly lamented 3dfx prior to the launch of the VSA-100 about the extreme blurring they were going to introduce because of the white paper they released going over exactly how they implemented their algorithm. Two 3dfx engineers jumped all over me- again- all publicly- and we had a rather loud public argument about it for several months. Then the part shipped, everyone bitched about exactly what I told them they would, they updated their algorithm with compensation for their improper mip calculations due to the nature of their multi frame sampling.

Getting granularity on your calculations to a point where you eliminate visible errata is in essence what I do for a living, this is the same math used in a different fashion Smile
