It is somewhat infeasible to use linear colorspace, because you need a lot more precision in order to do this without banding. You end up with substantially bigger texture maps, possibly twice as big; but actually it ends up being a lot mor

Actually, the effect happens just as much during downscaling. It is just not as noticeable, because your artifacts happen at subpixel scale. But they do affect the output colors. The math does not really know the difference between upscalin

You are thinking of a different gamma-correction step. The reason you gamma-correct during rendering is because monitors expect data to already be gamma-corrected, and it is this expectation that causes the problem I am talking about. Data

Some time ago, I wrote some articles on image scaling that go into a bit more technical depth (with a specific focus on mipmapping): http://number-none.com/product/Mipmapping,%20Part%201/index.... http:/&#x2

Among the potential solutions, he doesn't mention reversible computing, which I found weird, because the whole point of reversible computing is drastic reduction in power draw. Maybe he doesn't think it would ever be fast enough,

Hofstadter's stuff is not remotely GOFAI. Have you read his books or looked at any of the projects?

Yes, it is not possible. Learn about what a Z Buffer is and how it works. Dude seriously, I have been doing this a long time. I am going to stop replying after saying just one more thing: If you are running on an OS like Windows (which this

You are correct. The whole reason things are set up this way is historical, compatibility with CRTs.

Triple-buffering doesn't help that much, and it adds an extra frame of latency, which is really bad.

Well, I left the start of an explanation in another reply. But the problem is that you are asking a question where it takes years to really understand the answer, and certainly hours for a commenter to write a summary. For someone to put th

See my Rocket comment above. But in reply to this specific comment I will drop you a hint (this hint is still just a small piece of the whole situation): 3D rendering is so deeply pipelined that it is difficult or even impossible for the pr

Look into what is involved in modern 3D rendering of high-detail scenes. It is NON-TRIVIAL, and I can tell you this as someone who has done 3D programming for 17 years. Pro Tip: If an entire industry of experienced people finds something ve

This is a contemptible article. It seems mostly to be a product of PR, and for an American audience it seems intended to perpetuate the cognitive capture regarding razors being things that a lot of thought goes into and that therefore justi

The article is hard to read because it feels like this guy is really fooling himself. If he were as good in academia as his rhetoric claims (building software that "revolutionized" a field) he should have no problems. He should no

But isn't that how tech conferences usually work? And doesn't that result in the kind of gender ratio problem about which there is much dismay? Agreed, they did this in a clumsy way, but hey, they are trying something.

I have done meditation for years now and found it to be very beneficial. However, I find this article to be very Cargo Cult and am disturbed that nowhere in this entire thread has it been called out as such. "Look! Meditation must do t

I think it just plugs into the Ayn Randian / objectivist mindset. "Some people are hard workers, and others are parasites, let's identify the parasites and axe them and we will have a utopia." Yes, nobody thinks of it in

The author of this article does not seem to understand what good PR agencies do. He thinks PR means 'web spam'. A good PR agency is about human connections: they will get press interested in doing a story, they will get you live i

Yet another Visual Studio, yet another truckload of "features" that do nothing to help day-to-day, heavy-lifting programmers. (And which probably help by adding bugs or just bloating the system). Sigh. I am hoping they have made substantial

Whatever. It is easy to make a single decision that is right or wrong. Or, a decision can be right given limited information ("this thing has low odds of paying off"), but "wrong" given what actually happens ("what do you know, against odds

From the perspective of their own frame, photons don't travel. They are everywhere along their path at once. From our perspective, a photon goes through A first, then B. From the photon's perspective, that is not how it is. So the concept o

You may want to read up further on Fermat's principle. Your response is a little bit ill-formed because Fermat's principle is about the time to travel between two points. You assert that light is not "taking the shorter path", but in doing
