Actually, the initialization is completely random. The reason why it might seem too optimal is because the algorithm chooses the colors most similar to the image when rendering the triangles.

Cool! I'm guessing you use an edge detection algorithm like https://github.com/esimov/triangle?

This is amazing! Is there any way to download this in a 3D file format?

For low-poly art, I wonder if there could be a way to only triangulate a specific area. (eg. only the pet and not the background)
Also, if you need something less aliased, check out Triangle [1], a similar and awesome tool!

That sounds super cool! I'd be interested in seeing a picture if you end up doing it. Let me know if you need any help with the API!

I originally intended this to be a generative art side project, but there's been a magnitude of great ideas commented here!
The graph idea could work, but the algorithm produces slightly different results each time it is ran. It still could be really interesting to try!

Not particularly, but Go is fast, compiles to small binaries, and supports multithreading with coroutines which works well for genetic algorithms.

Triangula uses a modified genetic algorithm which I wrote about on the wiki here [1]. The reason I didn't use simulated annealing is because I ran some tests and found it was generally less effective for my case.

I found Wails very simple to use, and would highly recommend it to anyone looking for a lightweight GUI library.
However, Wails v1 uses mshtml (basically ie11) on Windows, so some features are unavailable.
Wails uses Webpack so you need npm installed when developing your app.
You might also be interested in Tauri [1] which is a similar framework but in Rust.

Blurring is a good idea! It could work with placeholder images, but it'll probably be better with smaller ones (eg. profile pictures).

Thanks! The algorithm works iteratively, so essentially each iteration it makes small changes and then checks if these changes are optimal. (There are many more details described on the wiki [1])
The frames of the glasses were preserved because the algorithm "decided" that it was optimal to keep them with the limited number of points it has to work with.

That's an interesting idea! I suppose it could be used for compression, although my intentions were for this to be a generative art project.
I triangulated a 1988×1491 jpg using 10,000 points and managed to reduce the size to 20% of the original size, but the triangles could still obviously be seen.
Many people commented on my initial post on how Triangula could be used for LQIPs. I've created a library called tip [1] for this purpose, which is currently not production ready but should work for almost all cases.
Any feedback for both projects is appreciated!
