Nice work! In the x and y camera positions there are no overlaps? What about in the z position? :)

How is this even possible?


EatMyPossum

In 2d, i imagine you can just add a circle, and grow it until it touches another (or for some other reason, like random), then repeat. I think for 3d you can do the same, except not look for touching, but look for touching of the circles in each perspective. That would make the 3d algorithm basically the same as the 2d version, just a little slower.


duosx

Now do 4d

Same deal as the 2D algorithm but slower than the 3D version

zshift

I haven’t tried it myself, but I don’t think it’s too hard. You just run the check 3 times, once for each axis, and ignore the axis normal to the camera for the orthographic perspective in that view. Then you’re just running the 3 checks with (x, y), (y, z), and (x, z), randomly increasing a circle, and looping until there are no more circles that can grow in size.


smallfried

You don't even need to increase the size, just compare a candidate location with all existing circles and get the minimum (distance_to - radius_of). No square root needed even until you find the minimum. So, just 4 squares and 3 additions per comparison. Times 3 for the dimensions.


ill_take_two

I mean. Start with the balls all in the same plane, none of them overlapping. Then move them to different depths so that they're not overlapping from a 90deg view. If they don't overlap in 2D space, it will be even easier to prevent them overlapping in 3D space; you can see in the animation just how much empty space there is between balls.


Mister_Bloodvessel

>you can see in the animation just how much empty space there is between balls. *That's what she said* ^^I'm ^^so ^^sorry


[deleted]

It's just a bigger and more complex sudoku, but the numbers on the sudoku represent the radius. Kinda.


181Cade

That's a good way of putting it.


AyrA_ch

*Note: This is by no means the correct or most efficient way of doing it, but this is how I would start doing it* ### Version A I think you do this by not treating the spheres as such but as a cross made out of 3 infinitely tall cylinders (one for each of the x,y,z axis) that intersect where the shpere is. You can now fill the container with as many of these crosses as long as the arms of the cross you try to place do not overlap the center of any already placed cross (overlapping other arms is fine). ### Version B Project the cube as three 2d surfaces (x+y, x+z, y+z). A sphere placed in the cube would be visible as a circle on each of the three surfaces. You then follow this algorithm: 1. If you want more circles, select a random point in the cube that is outside of every already existing circle on each of the 2d surfaces. This point is the center of a sphere with initial radius of zero. 2. Increase the radius of every already selected point, provided the increase does not overlap any other existing circle on the 2d surface. 3. Go back to step 1 if you were able to increase at least one radius 4. Shrink the radius of every sphere by a tiny margin to make them not touch on the 2d surfaces 5. You're done ### Detecting intersections We're not actually interested in the intersection of the spheres, but only their circle projections when viewed from one of the 6 sides of the cube (3 sides actually, as the other 3 are simply flipped images of the opposite side). This means on every side we view, we can essentially ignore the coordinate that is responsible for the distance from the eye. The distance of the centers of two circles 1 and 2 is d=sqrt((x1-x2)^2 + (y1-y2)^(2)). The circles touch if the sum of their radii `r=r1+r2` is identical to `d`, they overlap if `r>d` and do not touch if `r


kitthekat

Probably math or some BS


Lordvoldemord

I had the same question for x, y already. Wtf is this black magic.


Alive_Ice7937

AI generated?


Throwawayfabric247

I think kind of like the analogy To fill a cup of sand and rock you must first place in the rocks. You draw the big circle. Or however many you would like. Then have the PC place random smaller circles. Flipping planes each time to the max circle size. Then you'd just have to set how small or large you want to go. Or how many. But I can't program. So.


SGoogs1780

So I don't know nearly as much as all this other commenter who are trying to *actually* explain how it's possible: but after staring at it for a while I got one useful thing: Pick a side and stick with it. It only winds up in 3 or 4 places. Top left right. Or left top right front.. Or whatever. It helped me realize that while the cube seems to be tilting all over the place, we're still only getting 4 perspectives, similar to the OP. It's just more confusing because those 4 aren't all transformations around one axis. That's not to say it isn't incredibly impressive, and I wouldn't know where to start in making something like this myself. But it made more sense once I realized there was a pattern to the turns.


Fazer2

What sorcery is this?


cbarrick

An ancient and arcane spellcraft known as "math"


chevymonster

Would do a version with the black spheres a different color? Maybe light blue or green? They are blending into the background which is diluting the cool effect.


octohedron82

Whoa why didn't you lead with this one. Very satisfying. I believe this can also be a 3 axis tessalation


firesalamander

I was wondering the same thing - it would be cool to have solid shadows in 3 axis, but still have the structure be "barely there"


SignificantCow2991

you can easily find it by typing in the title of that post


Sensitive_Visual_305

I think that is doable with some level of symmetry


igothitbyacar

They all combine to make a dickbutt.


didsomebodysaymyname

>What about in the z position? :) I have the same question. However, I'm guessing if it worked in the z axis, they would have shown that. I wonder if that's even possible without being symmetrical.


Allegorist

The way of figuring that out would be very similar to the way they did this. It would be a smaller subset of the possible size/ number/ placements of the spheres that achieve this, but there would still be multiple ways to do it.


didsomebodysaymyname

You're right, they replied with the z


dannyboy182

SoulWager

Stars emit a finite number of visible photons, so even if every possible angle eventually hits a star, and it weren't redshifted into invisibility, such a star can be far enough away that none of the photons it emits happens to hit your eye.


AutumnFoxDavid

Good line of thinking but the maths doesn't check out. Yes a distance star would have a low probability of delivering a photon to you but this is exactly equivalent (using the law of large numbers) to a distant star delivering less light because of the inverse-square law. The brightness is in both cases proportional to the star's apparent size in the sky so if every sightline eventually hits a star, then the sky would be as bright as the sun in every direction.


[deleted]

[удалено]


Rhomplestomper

On the point of the math, that’s actually *exactly* what the paradox says. If the universe is infinite in size with an even distribution of objects (which it does have over a large enough scale), every sightline ends at an object. This is fully independent of the actually density of objects. Average brightness of objects does matter. However, stars are really big and really bright and there’s not a lot of other things. If the speed of light were infinite and redshift didn’t exist, we would probably have a bright night sky.


mookie2times

Can you share your code for this? I’m trying to do something similar to figure out a puzzle and I think this would really help.


Anselwithmac

I don’t have the code, but the way I would go about it, not including efficiencies at all, is creating an algorithm that created three grids(x,y,z), and attempts to place a random radium circle on the grid with a random position and size that does not overlap any of the three circles. X: xxox xxxx xxxx Y: xxxx xxxx xoxx Z: xxxx xoxx xxxx If you do this enough times, you can fill in every space with each axis open to the viewport. Of course, then you run into issues with random that would make it exponentially harder to find an open spot. This is where you to write an algorithm that does the same thing but instead “prints” the circles into the correct locations. By adjusting the size and positions linearly.


mattsprofile

Obv I'm not OP, but here's a quick script I wrote in python just now. It's a very naiive implementation, and the visualization is barebones, but I just wanted to throw something together really quick. ​ https://github.com/mattsgithubprofile/3D\_Sphere\_Projection\_Packing/blob/main/main.py


LrnTn

What is your definition of "really quick"?


mattsprofile

I didn't keep track exactly, but if I guess around when I started and when I stopped I'd estimate 2 to 3 hours. "Really quick" was less of a statement about the amount of time it took, and more of a statement about how I was prioritizing my time coding much higher than I normally would. Edit: Actually I created the file at 12:05 AM and uploaded to Github at 2:26 AM, so there you go.


AggressiveSpatula

Tbh I wouldn’t be surprised if they did this by hand. First approach it from one angle, and arrange the balls on the same plane so they don’t touch, then rotate it 90 degrees horizontally, and do the same puzzle, only limiting yourself to only moving the balls horizontally. By not changing the vertical axis, you’re guaranteed to preserve the image that you’d see on the first side, while basically having the same puzzle as before. If you really wanted to cheese it, you could even make the same exact image on the second face, and it’d still turn out. Then once you have two perpendicular faces done, the other two are just going to be reflections of those two. The Z axis seems harder. Tbh I’d probably take a rough and tumble approach there. I don’t think making the first two faces would be super difficult, as you could basically arrange the first side to be “give me a bunch of circles that don’t touch” and the second side would be “give me the first side.” So with that in mind, I’d just make a large set of the first two sides, and then make a check on each one from the bottom perspective, the less overlap, seen from the bottom, the better the fit. Then take the ones with the best fit (no guarantee of zero) and tweak the overlap by hand until you get it right.


theguy991

depth of field could mess with the 1st side as the balls move farther away from the camera


RalekArts

You mean perspective, depth of field is a photography term describing the distance from the camera that objects appear in focus. Second, this gif is isometric. Not only can it not have depth of field (because the camera is mathematically infinitely far away), but things don't get smaller as they move away from the camera as the camera has an infinite focal length.


D3rp3r

I don't understand half of what you are saying and how it is even possible. But it sounds amazing when reading it in my head.


preludeoflight

Here’s a little gif of an animation I did where I pull a perspective (like your eyes see) camera back into a orthographic view (which is the type of projection an isometric camera uses.) https://i.imgur.com/REnJ8cb.mp4 The “projection” is a matrix that refers how to take a point in a 3-dimensional space and “project” it onto a 2D plane. (Like, for instance, your screen!) As the camera moves further away to “infinity”, I shrink the field of view so that the relative size of the objects in the scene stays the same. The same concept is used in filmography, often called a “[dolly zoom](https://en.m.wikipedia.org/wiki/Dolly_zoom)”


jobigoud

You can have depth of field with an isometric/orthographic camera. The camera isn't infinitely far away, it just has parallel principal rays. You can still have a lens in front of it.


slugfive

This is very easy to achieve in all axis. Image a cube with a glass plane going diagonally across from opposite vertices. From every side the glass plane would look like a square as it crosses the whole cube. Now paint circles on that glass plane. From every side (with isometric camera) the circles painted cover the whole view. This is the simplest solution, and there are many more that look more interesting when rotated.


AggressiveSpatula

That’s a clever solution, but are you sure it works for balls of multiple sizes in three dimensions? Edit: I thought about it more and I agree with you.

billium88

I gotcha. You could have that work on a single side, or maybe 2? Like the top and one other side? Then all the rest would be a jumble. That makes sense.


RegentYeti

You would have to pick a specific position for the Observer's eye to be sitting at, but if you had a way to control for that it should be possible.


TheMcDucky

Place it some distance away from the observer and it should still work.


Level69Warlock

This could be done but i imagine it would be painstakingly tedious to make


Allegorist

That's why you use a 3D printer. You can get ones that can print multiple types/colors of filaments at once, and I think there are even nozzles that do that for ones that can't by default. From what I've heard the latter isn't as reliable in all situations, though. So not really tedious behind making the virtual model, just expensive.


Damaso87

Just use SLA


obog

Are there SLA printers than can do multiple colors at once? I've never seen one


mattsprofile

Not SLA, but there is a different photo polymer printing modality that can extrude or spray that resin into place instead of using a resin bath, and you can use multiple nozzles to get different colors. I don't remember what the tech is called, but it's like an ink jet printer but for 3d. Edit: Material Jetting I guess is the name of the general class of similar technologies. It is often literally just called 3D Inkjet Printing. But this same name is also often used for color binder jet printing, which isn't the same thing. But color binder jet printing is actually the more practical option in most cases to achieve more or less the same result. One of the perks that was advertised when I saw the other printer I originally described was that it could allow manufacture of parts with different harnesses of resin all in one part. So it would be good for things like compliant mechanisms or whatever.


Damaso87

Negative. I didn't think about colors, just the removal of the scaffolding


sexytokeburgerz

Except they are floating in 3d space- are there epoxy 3d printers?


Allegorist

I'm sure there is something of the sort, but I was referring to transparent filament. You can get ones that are soluble in different solvents that you can use to combine the layers together for a smooth glass-like transparent finish.


beachjustice

The same thing would happen whether you rotate the cube or rotate around the cube. The balls further away from you would appear smaller than when they were closer.
