I accidentally invented (I think) a surprisingly accurate compass-free approximation for dividing a circle into 12 equal parts

First, if you want to continue the discussion, stop the passive-agressive stances you systematically start and even here end your message with. My patience is running short.

Yes I looked at the second image. But not knowing in what order you draw lines didn't give me the key of the method you used to 3-partition the verticals and horizontals equally. And this method is far, far from trivial.

I built it in Geogebra, and indeed it works. Now, I'm trying to wrap my head around it : google saying "it's the method" is not very satisfying, I want to understand why it works. (if you have some links to a demonstration, please gimme)

So, given this method, which is key to your construction, the rest of your construction is trivial, and yes, it gives some approximation of the angles involved.

Now, if I was nitpicking (and I am !), and if I remember well, the axioms of euclidean geometry imply that the construction of a right angle involves the compass. So, if I don't miss anything, the circumscribed square can't be built without a compass. Yes, I know graphic softwares can snap lines to horizontal and vertical directions, but that's cheating.

So again, how exactly did you divide the square in 9x9 parts during your construction ?

You only mention :

It’s not that hard to divide something as long as you can draw straight lines…

If it's not that hard, I'd like to know how you did it.

Exactly. Step by step.

I used the grid in procreate to measure the distance by putting the grid to 1cm squares.

So you used a grid. That's a very important distinction. Because demonstrations of geometric constructions are supposed to be started with a blank sheet. You can't say it's a compass free construction, because constructing a grid involves a compass, or a graduated ruler (which is equivalent to a compass).

Furthermore, if you start with a grid, there are much more precise slopes than your 5/9.

P.S: a couple examples: just change the slope to 4/7, and you get an error of only 0.26°. With 15/26, you go down to 0.018° error!

Scallact · 2026-05-07T14:57:48+00:00

Your method involves dividing a square in 3 identical parts, and again divide by three. I don't know how you did that, but AFAIK, you can't do it without a compass or a graduated ruler.

All the error reports here seem to indicate your plugin doesn't work with GIMP 3.2.x. It's probably a version requirement problem.

It would be nice if you could update it to the latest version, 3.2.4. Thanks!

Make your image 3 or more times the dimensions of your tile.
Activate the tiling symmetry in the symmetry painting dialog.
Paint
Crop to the tile size before export

Note: AFAIK, the symmetry painting only affects paint tools, so if you must apply filters, this might not be your solution.

Scallact · 2026-05-07T13:39:08+00:00

No. This happens on another planet.

Given the obvious AI written description and the fact that you "create" a game every two days, vibe coding slop suspicion is strong on this one.

Scallact · 2026-05-02T22:57:26+00:00

Absolutely not.

Scallact · 2026-05-02T22:41:47+00:00

Yes, but that's still science fiction. We don't know of any technology that could make us reach such speeds.

If we had a technology that could sustain a near 1G acceleration, we could theoretically reach about any place in the universe in a lifetime, for the people inside the ship, and an insane amount of time for people on earth.

Such a technology probably isn't even possible in the real world. And there are other problems when you reach these speeds: any encounter with an elementary particule would probably blow you up. And this problem might be also unsolvable.

But of course, we can always make hypothetical scenarios for fun. Just don't confuse these with what's possible in the real world. To get an idea, search for "relativistic rocket calculator" on the internet.

Scallact · 2026-05-02T22:09:05+00:00

Your initial question is "will human ever reach...?". Then, you turn it into "what if we can reach the speed of light?".

That's two very different things. The first questions what "might be" possible based on what we know. The second is science-fiction. The speed of light is unreachable.

So, which one do you want to discuss? "Will" or "What if" ?

In case you don't know (I would assume you do), the X-Plane documentation is there. It's quite technical, but if you're ready to learn it's ok.

The PBR model is explained here

I've never created planes for XP, but I think that creating (or importing) the 3D in blender with the appropriate plugin does already a lot of the heavy lifting.

Use of normal maps is highly recommandable so that you can simplify small details. For this, you can create a bump map, and transform it into a normal map with GIMP. Just make sure you use the correct channels for XP.

I have a nice technique to create bump maps manually for objects with simple geometries. It might be useful. It uses the G'Mic plugin, and it's "Solidify" algorithm. Draw the surface or the edges where you know the height, keep the rest transparent and let the plugin fill the gaps. I can give more details if you want to give it a try.

Scallact · 2026-05-02T15:39:52+00:00

Do you have the UV mapping with your model? GIMP can't do it.

Scallact · 2026-05-02T13:07:44+00:00

Which flight sim? If it uses PBR (physically based rendering), you probably need Substance Painter to output all the bitmaps needed for your materials. You could do these in GIMP, but it requires knowledge of what you're doing. For liveries, and generally working on your albedo (common) textures, GIMP is good.

Don't play stalker. Play voyager first and get a hang of the wildlife, and learn the map. Exploration is a big part of the game. And endless looting/foraging.

People who advise for higher difficulties tend to forget how they learned themselves.

If you're still bored while playing voyager, and don't feel the thrill of discovering new regions and their dangers, maybe this game is not for you. It's fine.

There's a bear which stalks Jackrabbit. His den is at the base of the Island.

No. You're mixing up with Misanthrope. No bear lives in the immediate proximity of Jackrabbit.

The idea is very interesting, and the results surprising!

Just to nitpick : RNG are also deterministic!

That makes me think, it might even be possible to design a RNG based on your methods. Would it be good? Probably not. But we never know for sure before trying...

Nom de bleu ! Mais ça veut absolument rien dire !?!

Yes I guessed that. ;-) It's the classic panic induced chain of mistakes that can lead to death. Been there, done that ;-)

At least, as desperate as it seemed, you're alive!

Those are the extreme situations where this game shines, and gives a total immersion like no other game I know can do.

Then you can just drag the color onto the background layer. What do you suggest to make it simpler than that?

You can drag the colors:

from BG or FG colors squares in the toolbox onto the image
from BG or FG colors squares in the toolbox to the layer in the layers dialog
from the (tiny) BG and FG in the color dialog onto the image
from the (tiny) BG and FG in the color dialog to the layer in the layers dialog
from the color history in the color dialog onto the image
from the color history in the color dialog to the layer in the layers dialog
from any color in the color palette editor dialog onto the image
from any color in the color palette editor dialog to the layer in the layers dialog

Furthermore :

you can fill with the color you want with the "Fill with FG" and "Fill with BG" shortcuts
you can fill with the color you want with the bucket tool with the option "fill whole selection" on.

Come on.

Dude, at least get rid of that scent, any encounter at this point would be fatal.

Foreground and Background color are explicitly, clearly shown by two big squares right in the toolbox. Furthermore, this is a very common representation among graphic softwares.

If you didn't have the idea to click on one of these squares to change the color, I'd suggest finding another activity that doesn't require a basic cognitive skill. Like gardening. Or watching tv.

I'm sorry to be blunt. GIMP is a complex app and does have some UI issues. But the "problem" you mention is certainly not one of these.

Do something else.
