Can be done with Gimp. I can't be bothered at the minute though. Gave it a quick try but it wasn't worth posting.

Just for fun I guess, for a time before knowing how with the superior round caps in stroke path

Anyone else got a shape/logo they'd like to challenge people with to share on here?...I think trying to reproduce a logo would be a fun hobby...not much use since you can't really use it for anything because it's all copyrighted.heheeh

I was just thinking if paths can be upscaled and downscaled when you resize and image (I tried to use offnuts script to draw multiple circles and then upscaled the image and the paths get upscaled as well)...Does this mean that if we use paths to draw everything, it'd be like a vector graphics program, we don't lose quality ever?
I mean offnuts circles are perfect circles no matter what I scale it too...Gimp just got that much cooler I thought.

so this led me to think what if instead of up-scaling the original image which gives poor results, what if i color selected the shape from original, turned that to a path, then upscale that and then path to selection and then fill it the selection with original color the result is pretty good (so it's totally like up-scaling a vector).
here's the result of that

it's not perfect as you can see some warping around the arc's edges, but that has to do with me selecting from the original image with a not so perfect threshold.

But I think it is a lot better than just up-scaling the original which looks like this:

(Given the source XCF, no paths involved

here's my try. it was challenging and fun. There's some artifacts around the fine lines as i was selecting by color and cutting and replacing with colors i wanted.

I gave it a go and came pretty close I think, but there seems to be something that's not quite right.
Getting the top and bottom parts of the cube to look correct is the trick, whatever that might be.

another try,
i even lucked out produced the same see through right at the edges where the faces meet.

Quite good. IIRC, starting with a square with a round hole you need to scale horizontally and shear it once (gets you two of the vertical faces) and then flip that result (gets you the other two vertical faces). Top and bottom are a 45° rotation and a scaling.

It's the scaling of those top and bottom parts, that I find the most difficult to do.

I didn't shear, I made a square with a hole in it, then rotated 45 degrees,
and scaled the height of that result to be sqrt(((0.5(x))^2)/3)*2 where x is the width distance of the rotated 45 degree angle square (or the length of diagonal of the original square except now its' rotated it so it's just horizontal width).
Once I have this shape (the top), I just rotated 180 degrees to get the bottom, and then all the others sides are just different rotations of that piece.

Here's more details on how i did it.
after having the rotated 45 degree square with hole

Now i wanted to scale the height down such that the result has height equal to the diagonal sides which are all changing as you scale.
So I doodled something like this

I know x since i am keeping the width the same when scaling, just solve for a
x^2 + a^2 = (2a)^2
x^2 + a^2 = 4a^2
x^2 = 3a^2
(x^2)/3 = a^2
sqrt((x^2)/3) = a
and there you have have 2a is my new height.

Basic trig:


So to get from square starting image to a side panel:
- shear vertically by 50% of original height (ie. sin(30deg) )
- scale horizontally by 86.6% (ie. cos(30deg) )
Then just duplicate and flip to get the other sides:



To get the top, duplicate one of the front sides and rotate by 120 degrees about the centre of the image.
To make the bottom, duplicate top and align to bottom of image.



Note that the image Ofnuts posted has slightly "gappy" edges - to reproduce that effect precisely you need to make a slight transparent border around the starting image.

I enjoyed this one because it involved trig or pythagorean.

I'm sure you could do a script for it, Tin!

Wouldn't want to take away people's opportunity to brush up on math...actually i am just lazy and don't think the script will be popular use. hehehe

** slaps forehead ** Good one.

Yes; surprisingly easy once Tran mentioned the 120º flip idea. Just create the square with punched hole. Rotate 45º. Then do the simple relationship of [H]*Tan(30º)/1 {Tan(45º)=1; technically it should be H/2 not H, but then you have to multiply by 2 to get the new height anyway so it's a wash} for the new scaled height keeping the width the same. Then it's just a matter of rotating left 120º for one side, aligning the edges, mirror flipping for the other side, merge visible, dup, and vertical flip to complete. Then, just a matter of shading the sides. Sorry for my lazy alignment. lol

It's a seamless design, am i gonna see a field of cubes?

You just had to encourage me to re-open my binge didn't you Tran. lol

Redid the cube (bit more accurate), then voila. It's a PNG with transparency; just wish, when you first click to expand, you would get the gray colored background to validate the transparent background like you use to here.

hahaha there's my man!
wait there's white space in your render...I thought i would do one that fills everything with cubes


although, they don't look like cubes anymore. More like stars.
