Why are all computer images squares? Why can't we have circular pictures and monitors?

Subpixels don't exist man. There are pixels, and then there is "sub pixel rendering" which is just rendering that takes into account the pixels physical makeup.

When everything is a circle you will waste all that fucking corner space. Instead of perfect screen usage you have massive gaps. This happens even if the physical screen is a circle.

You see that those are just normal rectangles right. There is no rearranging them into anything else.

Right so when I have one image, and then another image next to it, no wasted space? You literally cant pack circles and not have wasted space. Not without extra dimensional time bending bullshit that does not exist on 2d screens.

Paper - the first output medium - is rectangular, because that's what's most practical for displaying text. This carried over to first screens and we just never bothered to change it. Even if circular screens were beneficial, just look at qwerty and how we're stuck with it, even though changing keyboard layout is basically free.

No, it's closer to an ellipse.

Circular displays don't make since at all even if it was free to instantly change. Op needs to explain what the fuck a system would even look like that does not waste all screen space.


 No.880822

Rectangles are easy to work with for a bunch of reasons.

Possibly the most important one for computer screens is that the most practical coordinate system is rectangle-based.

Another really important (but not entirely distinct) one is that you can pack rectangles with very little fuss. If you need to fill a shape with similarly-shaped differently-proportioned shapes without rotating them you can't do much better than rectangles.


 No.880823

>>880819

And I'm saying that it doesn't matter whether they make sense or not, because it'd be too costly to change to it.


 No.880827

>>880823

>because it'd be too costly to change to it.

If it made enough difference it could be changed, especially in new things like VR. In the case of qwerty the difference is just not enough to matter. You won't be typing 50% faster. I use dvorak for everything, not THAT MUCH better than before. Feels nicer to type tho.


 No.880829

>>880822

They don't make much sense for UI, but circles (or rather ellipses) would make perfect sense for videos. And not just for the sake of viewing, but also because in cameras you're actually wasting pixels by using rectangles.


 No.880830

Because circles are mathematically a pain in the ass to deal with in any capacity.

Really? Then why are brains not cubes?


 No.880835

The same reason we don't have round books.


 No.880836

One way or the other, there will be wasted information. How many circular documents do you have verses square? If you're like most people, the answer is none or almost none. Pixels are arranged in a matrix so if you have a circular display you will always have to support additional discarded corners. Until someone invents displays with radian output and rasterization, it would be a total waste.


 No.880837

>>880830

Obviously any math would have to be based around angle+distance from centre, rather than what we're using for rectangles.

 No.880895

>>880873

No, I'm irked because the earth is a sphere, and that map isn't behaving like a sphere at all. It's stretching the poles horizontally to avoid deforming America and Asia, but it shouldn't treat the poles differently from any other area a quarter way around the earth. And the opposite to the origin of the radar should be stretched all around the circumference, not appear just at two sides.

It's favoring a horizontal projection, which is very suitable for maps but not for something like this.

It`s a matter of area and stacking, both in the production process and in the product usage, mapping and workability.

Also, the Square is the perfect figure of two dimensions.

Not doing it squared is the ultimate retardation.


 No.880938

Only squares stack perfectly. All other shapes either waste space between members of a grid, or waste perimeter by making borders of the grid irregular. It also has the advantage that rectangles of different sizes also happen to be stackable with ease. Rectangular screens are simply the best shape to convey the highest possible data density.

Because they are impractical in about any sense. Dimensions are basically always defined in terms of straight lines (whatever is parallel or perpendicular to a coordinate axis is considered "straight"), and only after you have a coordinate system defined by perpendicular lines do you define circles. Matrices are perpendicular as well. Squares are exact even with low resolution, while circles are always only approximated.

This is also evidenced by the fact that circular displays are found in older analog systems. The angular index requires a continuous range for true accuracy.

Is there any other significantly different celestial mechanics concept that would explain what can be seen in the sky equally well? The Ptolemeian system was surprisingly accurate (at least for the time) once epicycles were introduced into it and nobody complained much about its supposed inaccuracy for more than a millenium until the inertia of the church's influence was overcome and the Copernican system was widely accepted.

Also, why won't flatearthers simply fork Stellarium and change its algorithms to correspond with their views if they are so sure of them? Shouldn't Flatterrarium(tm) be much more accurate if based on """true""" premises instead of the """false""" ones like Stellarium? Wouldn't that be their victory?
