Pixel Circle / Oval Generator

Nice. I like the javascript effects.

If anybody else is interested in a 3d version, I have one over at:

http://oranj.io/blog/voxel-sphere-generator-77

I think it should have an option to download a picture of it and a zoom out button when for my mob arena im working at 223 X 223 its very hard to have to scroll and I end up printscreening it

Is there a download to this?

how do i see my result, theres no where to hit enter or something to send my numbers through or something.

I have been using this generator for nearly a year on my phone with no issues. I have been making semi circles in my castle that step up each level so it has a colisseum look. However, every time I load this page, in the box were width and height are, all that's entered in there is NaN. I can't add to or delete it. Rendering this generator useless to mw now, and there are no other generators that work for me. Marvellous.

Having a few issues with this program. Trying to create a sphere to encapsulate the spawnable area for hostile mobs (wiki: 128 radius from player). So I doubled the radius to 256 then generate a sphere based on that. Before I started I plotted out 6 points all starting out from the 0/0 axis in the end (which I removed all end stone). Markers were placed exactly 128 bocks up, down, left and right so it covers all X/Y/Z directions. When building the sphere I noticed that the 2D sides did not meet up with my (triple checked) reference points mentioned above. The sphere generated by this program seemed too big ( by quite a sizeable margin I might add). Thinking it was my error I recounted the chart...three times...rebuilt...three times...but still no joy. This is a great generator to make spheres...not denying that....but for really technical mapping it's fairly inaccurate in "true to size" builds. Sorry to rain on your parade but thinking I might add this footnote for other builders like myself thus saving them time. But hey....if your just after a good looking sphere this is the program for you.

Your math is simply bad. If you have a radius of 128 the diameter in pixel universe will be 255, not 256, because one of those blocks is the center. That is your issue.

My circles are mathematically correct. The math in fact is particularly simple.

While I love this generator the png downloads will not open and a preview of them says the file contains nothing :/, love to get some feedback to resolve this problem if anyone else encounters or has encountered it

How big would i make a circle around a 50*50 build?

Love how the file was just called soup,lmao

Truth is, I just want to be part of the 10 year comment archive! Great tool btw, I have been using it for years, mainly in minecraft builds. Thanks for keeping it online.

Is there a way to see how many blocks to fill in the circle?

Does anybody know why exporting a circle with a radius of one hundred and fifty-two (152) as a PNG magically changes the width & height of the image to three thousand (3,000) pixels?

This tool is awesome, but it would be even better if there was an option to download an image of your circle in its native size, without grids or smoothing so that you could plop a couple of these down in Paint or whatever.

bro is answering people on the same day for 12 years straight
insane dedication to own's project

making a bunch of fruit-themed temples. this is a life saver. the watermelon one is coming along well.

love you bro

lifesaver bro I've been using you for years just wanted to say that the fact that this is free is incredible. I'll get around to donating eventually, I promise!

Thanks bro, my underwater sphere will go in

I used this to make a circle but when I tried to create a sphere it didn't match in size.

You're amazing dude! Crazy that you still keep this thing running. I'll be back in 2034 lol.

IT helpet me a lot, with my base, thanks

So, this is probably a dumb question but, if i have a 40 block wide staircase trying to get into a circle.. what would i do to find the size of the circle to make it even?

hey just wanted to know if there is a way to download it as a png. im doing a 505/505 for my mega base and really need an over lay so i can get it positioned right thanks!!
also this helps so much!

>w<
Great Work

This is an amazing thing. You should add an option to display a number beside the different lengths of blocks so that anything above 4 you don't have to count. Also, you should clarify that it is calculated using a diameter, not a radius(maby add a option to switch between the two). It took me several attempts to figure out which one it was(This is because I forgot to subtract 1 from the Diameter when I originally tried it for a one-block center). But once I understood how it works it was a big help.

I wished there was a 3D one like this so I can make sandy checks house.

thanks for making this site it has helped me with minecraft, space engineers, and suprisingly terraria

how do I know how many blocks it takes to go from the center to the perimeter diagonally

This web is incredible, i'm from Spain so, acuse me if i have mistakes.
When i need to do a circle i go to this web, put the imputa and done, easy to do, and works perfectly, the only thing that i Will say IS that the zoom its a bit weird and whats the Matter on puttin y and x in the circle output but even with that, this web is awesome.

I'm following a comment from a couple of years ago where you explained the error in someone's math. I want to make a large, odd-numbered circle With a diameter of 257. I have my center point at 129 blocks from the edge of each cardinal direction. When I try to build the outside of one quadrant of the circle, I usually end up 1-2 blocks short of the cardinal direction I'm building toward. For example, if I place my center block at 0,0 and my southern-most point at 129, 0 and my eastern-most edge at 0,129 the edge of the circle usually ends up 1 block short at x:1 y: 128 despite triple-checking my build. Is it a simple error of placing an incorrect block or is my math not translating to a circle made of cubes? Thanks!

Bro straight up used algebra to help someone on his website. Abolsute W owner. Btw website is really amazing so thank you for taking the time to make it all those years ago.

Oh and I also read through every single comment lol

awesome tool.
coming back to this for so many things, not just sandbox games.

got some ideas for upgrades if you are still working on it.
one of the two following would be so much more handy.
i need to stack circles with different radius, but the PNG/SVG are always scaled to the same size.
would it be possible that the pictures are different size, but the single displayed pixel always got same size?
or, second idea:
would it be possible to calculate multiple circles at once? then the scaling wouldn't be important at all

And I could also see all of the well deserved praise this website deserves

Bro just read your About Me bit and I think a bit of my brain leaked out my ear. Lol

I am using this to build a large chateau based on the one in Blois it is very useful and i have also used it in many other projects.

Useful for building. very very thank you.

Can you please make it also show a string of numbers representing width of every step. Minecraft building tutorials usually show it when building circles. Want to mention that 23-diameter circle perfectly fits inside 25-diameter circle with thin border. I want to find more of theese pairs and this addition would help a lot

how do i make this with command blocks? java

I'm really going to have a hard time building my AOT wall project

Hey I've been using this generator for years, and this is a lot to ask, but I need a need a circle with radius 1806 blocks, and while this can do the math just fine, the downloaded images aren't high res enough for me to see the individual blocks. Any chance we could get an update with an option for very large images? I understand if not!

Disregard my last comment, .svg works I just had to use a different browser. Now I can make my stupidly big circle

is there a way to track the blocks we've placed down? i keep losing track on the diagram

Fontajo, now I'm curious what your stupidly big circle is for

I agree with Ely, an option to download a PNG/JPG/image in the circle's native size without grids/smoothing would be really helpful. Still, this is a lifesaver considering the difficulty I've had trying to get a circle tool to work in my art program. tysm!

Super great program. Thank you. If possible, could you add a circle divider? I cant wrap my brain around the calculations for knowing where the intersections of the devides sections are :I

if i have a 100 by 100 how do i add a 60 by 60 in the middle

Absolutely love this site and I have used it alot over the years but, When making bigger circles like the 512 by 512 im making rn its a bit hard to spot the middle so just some lines you can toggle to see the middle would help loads thx.

How do you make the circle in minecraft

Tks bro, im building my netherhub and this helped me S2

Thanks I found this really helpful

This really helped my scale build for a building I saw in a movie and its huge! Couldn't have done it without it.

@Fontajo why the heck do you need a 1806 by 1086 circle?

Been using this app for years and donated early on … but then I stopped playing for a few years. When I came back to it again recently, I found I had saved this page to the back back page of my phone’s desktop—and it’s still going strong! Kudos and much gratitude. Now I’m teaching my son how to play and this is a really fun tool.

This is the best pixel circle generator on the entire internet. I have generated thousands of circles (mostly for Minecraft) and on mega bases on anarchy servers such as 2b2t. The biggest I have made is a 4085 block circle and it worked perfectly. Thank you!

Is there some kind of bug with this website? I'm trying to make a 320 diameter circle but no matter what I do its always 319 blocks in diameter

I net a 170 x 170 for my super fast guardian farm

Very cool, i'm building a megabase and this is helping a lot. A cool option i'd think would be great to be there is able to select the colors of the block you color, not just purple, it would help highlight a part of a circle you're making, making it easier to make the circle, and help a bit if the circle is made fom a pallete of blocks. Very cool site tought.

I used this to create a large dam. Worked perfectly! Perfect arch. Thank you.

This was so helpful in trying to build a collection of hobbit holes
Most of them usually end up square and i haven't been able to work out how to fix them in the past

I used this to make a sphere thank u

This website has helped me make over 100 circles and it works literally perfectly.

Thank you for having this resource available for so long. Been using it over the years as I get better at building in MC. Just started work on an ocean monument with my friend in survival for a guardian farm and having this resource helped save so much time in plotting out the cylinder to drain.

I am uncomfortable with the level of lazy this page makes me feel. Many thanks for your work here. I am attempting to make a pentagram shaped river that is in a 401x401 circle in a game called Core Keeper. This tool was a sanity check. *bows*

You have no idea how much it helped me , thank you so much.

I am building a mega base comprising many circles and the biggest circle is 275 blocks in radius.

Again thank you so much for this tool.

should show center and how far it is from the side of the circle

Love this it helped me build my MC castle base (it was a circle of raised land) Keep on coding man

I am draining an ocean monument and this has really helped! Is there any way to be able to find the midpoint? Thanks

You should put number on each pixel, so we don't have to count each time :)

This website is really good but if you and your friend who made the 3D sphere generator combined the two websites that would be really useful as I like to build a bunch of spheres and circles combined and it gets annoying going through the two websites. Just a suggestion but it would be nice if you did it.

I love this generator, it has been really useful in a project where I'm building roads for a city, and they have all sorts of curves. However I wish you could be able to "split" the circle with fractions to get stuff like a quarter circle etc.

Replying to Lachlan.M:
I agree, I use this all the time to make really big smooth curves for railways in Minecraft, in fact I only found out about this through someone using it for the same thing. It would be very handy to split it into quarters and be able to just input the amount of blocks from the start of the curve to the corner and get a smooth curve for that

Cool website it helped with me build

are there different shapes like triangles and polygons??

Is there any way to get better pixels for larger circles? Specifically 500x500 circles?

i wanted to make a dome and at first i used this to make a cricle after that i went to some other site so i would see how i should build the dome and it made diffrent circle and now im confused because i dont know if my dome can now be done with circle from this site

Actually great!! Used in making circular buildings in Minecraft.

Thanks so much for this tool, i used it to get a pixel circle for a texture pack im making i needed a pixel circle in it, lil info - circle was for a pizza cutter lol

i literally depend on this tool!! also hi friends :3

Super useful! I use this for a game called bloxd io and its basically Minecraft but more simple, except for the code, you can play it in your browser btw! https://bloxd.io/

I tried to get your friends website approved (as I have a website block) but when my carer looked at it, it seemed to not load and look completely broken

I didn't notice at all that there were comments until just now. Hi, I've been using this for a few months for big builds (recreating locations from other games, so there are a lot of curves and circles and all that) and it is EXTREMELY useful. Hugely appreciate this, and the fact that it's still being updated!

Would be interesting to have an option of downloading the circle as a file for litematica. This site has been a life changer, thank you

been using this for years, it's great and has been an amazing help.

ALso i have a suggestion please add a darkmode theme and maybe other colors

yo! this thing is cool, really helpful when I build stuff, mostly stadiums for sports where you need circles and stuff

just one suggestion tho, please add a feature where you can see the sequence of blocks for building the circle

example:
15x15 circle would be
2,2,1,2,2

makes it easier to memorize

OMG thank you so much!! I have used your generator for so many of my projects, and the updates help so much!!

WHOA thank you so much for the update this is awesome! esp the middle line & better zoom

This is really helpful for my project! However, I would like to suggest a few things. Please add the diameter of the circle, or the length of blocks from the center. Also, adding a sequence of blocks would make it even better! Especially when working with large scale projects, just like SparkSan's comment.

I think it would be convenient if fractional widths and heights were allowed. I don't know if there's some algorithm that relies on them being integers... a priori, it doesn't seem necessary to constrain them to integers.

Also, I noticed that the way it decides whether to include a block in the circle or not is based on whether the center of the block is within the (mathematically accurate) circle. (Or, I think it is, unless I did my math wrong.) Options to include a block in the circle if the block is at all in the circle (check corner closest to center) or at all outside the circle (check corner furthest from center) would be nice - maybe I'll try forking the repo to see if I can add that.

I've made a pull request to add fractional radii and the option to check whether blocks are in the circle at blocks' corners (either the closest or furthest) instead of their centers. The latter works best for even-centered circles, where the part of a block closest to the center of the circle is always guaranteed to be a corner, not the center of a block or the center of an edge.

I'll probably use it myself (with the closest corner option) for a circular perimeter. Makes it feel slightly more correct, like "literally everything within this distance is mined down", instead of "everything within this distance (up to half a block) is mined down".

For small circles, checking corners gives results that look too square and less circle-like than checking the blocks' centers, but for massive circles, it's hardly noticeable.

This is a great tool, it helped me a lot.

This is so helpful I use it all the time. I was wondering if it would be possible to make a similar tool for calculating the smoothest straight line between 2 points. For example I'm trying to create a straight wall between the coordinates -60,77,548 and -72,77,522. Hope this makes sense lol

To the previous comment, just use the line tool on any pixel art engine such as ms paint. This will work because your line is essentially 2 dimensional as the y value is the same in both coordinates.

Hello i am making a mega base and i need to dig a octogon shaped hole so can you make a generater like this but for octogons

can you designe a tower generater my country is making Romania in minecrft so making towers would be so much easier with a generater that could generate towers and houses and stuff

It would be a useful if you could also select a thickness for the circle and it would add on those layers
