Generate high-quality triangulated and polygonal art from images.

triangula's Issues

[Feature Request] Add settings about 'max generations' to automatically pause or stop.

On my weak machine, the GUI application uses a lot of resources, works out of control and unstoppable. Even I can't save the generated result.

Would you like to add a settings about "max generation in one turn" to limit generating in one click on "Start"? If the generation match max value, it will automatically pause and waits for next "Start".

GUI not working: blank window

Hi, i downloaded the newest release (1.1.2) from the releasepage, ran chmod +x on the unzipped file and started the application.

A window titled "Triangula" pops up, but it's completely blank:

Console reads:

Left Side of Image Appears to Have Slight Triangulation Bias

This project is amazing. Thank you for building and uploading it. The outputs are remarkable and it makes computers seem like magic to me again.

It appears Triangula is somewhat biased to render / use triangle budget on the left side of images. Parts of an image further to the left seem to resolve to better detail. Not sure if it works better to allow images to process far longer, but it seems to stop making a difference after a while.

I don't know if this is either known, an actual issue, or helpful to you. Again, thanks for building something so cool and even... inspiring.

Allow capital file suffixes like .JPG in the file loading window

Hi,
i love your programm but I have a small suggestion for improvment :-)
When I want to load a new image using the GUI I can't select image files if the file suffix is in capital letters like image.JPG . I have to manually rename the file to image.jpg first. Maybe this can be fixed so that files ending with .JPG, .JPEG and .PNG can be selected too. Some Cameras and Smartphones save their images using suffixes like .JPG for some reason.
Best regards,
Marco

[Feature Request]: Dark Mode Support

I would like to request dark mode support for the gui. That way I won't burn my eyes whenever I use it. Thanks!

Stop button does not work if "Time per Frame" is set too low

If you set "Time per Frame" to 10 or 25 and start with triangulation you are not able to stop it with the "Stop" button, because it does not react. When "Time per Frame" is set to 250 the "Stop" button works as intended.

Incorrect documentation for CLI

This example from the docs not working:

triangula render -in <path to outputted JSON> -out <path to output SVG>

--reps CLI option does not work

Using the CLI version, it appears that the -r and --reps options are ignored, as well as the claimed default of 500 reps, since no matter whether I supply the options or not, the algorithm still proceeds beyond the supplied number and continues until killed with CTRL+C.

CLI and file extensions

I am doing this:

IN=schach.jpg
JSON=fitness
SVG=schach

triangula run -img "${IN}" -out "${JSON}"
triangula render -in "${JSON}.json" -img "${IN}" -out "${SVG}"

It is a bit weird to me that "-out" on run is adding a .json file extension even if I put in "fitness.json" already. A fallback for adding the extension is nice, but imho it should check if it is supplied already (strings.HasSuffix). That way I could use $JSON for both commands in the above example.

Interesting simularity

I have used a local optimiser to accomplish my goal.
This one uses delaunay for the startup only.

GUI unstoppable

When I make a run within the GUI MOST of the times the application is unstoppable.

• The stop button won't stop the run
• The X in the window won't close
• Even CTRL c in terminal won't halt the app
• Only kill -9 will

Unable to run Triangula on Windows 10

I had downloaded v1.1.2, but it's not able to run on Windows 10 (Version 20H2), would like to understand is there any tutorial for installtion?

Works great! Suggestion about referencing each other's projects

Hi there,

I saw your project mentioned on the Golang sub on Reddit. I knew about Wails already, but it never occurred to me that it produces such small and efficient binaries (when compared to Electron apps). I downloaded and played with your app. Great work!

The reason I am writing this issue is because I have recently written and self-published a book about generative art in Go (https://preslav.me/generative-art-in-golang/). I thought it would be a great idea if we refer to each other's projects. There is a section in my book that I am planning to expand upon, where I refer to other nice Go projects from the same domain. I suppose, I can put yours there in a future update. You could do the same, either as part of the README or in the Wiki.

How does that sound? Feel free to close the issue once you've read it.

Cheers,
Preslav

Cannot install go package due to capitalization in mod.go

Hi! I'd like to try your application but could not installed it locally on Fedora 38:

$ go install github.com/rh12503/triangula-cli/triangula@latest
go: github.com/rh12503/triangula-cli/triangula@latest: github.com/rh12503/[email protected]: parsing go.mod:
	module declares its path as: github.com/RH12503/Triangula-CLI
	        but was required as: github.com/rh12503/triangula-cli

I hope fixing the capitalization fixes this issue. Also, if it works, it'd be nice to adjust the README.md to use "install" instead of "get".

Cheers,
Maximilian.

triangles with gradient

it would be possible to use overlapping triangles with gradient to get different results

Tiny controls on 4K display (Windows 10)

Many thanks for the great project!

However on 4K displays on Windows 10 I get veeery tiny controls ;)

Size of controls doesn't change when resizing the window.

I have a white screen on startup

How do I build from source?

Hi, I cloned this repo and ran go build and got this error:

no Go files in C:\Users\milo5\Desktop\GitHub\triangula

Any ideas on how I can build from source?

My antivirus doesn't let me download the gui so I'm trying to self build it. Thanks!
