I've added a few examples of polygonal output to the README here [0]. 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 no

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! [1] https:&#x2F

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

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. [1] https:/&#x2F

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

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 bec

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 th

I was just thinking about adding another wiki page for that, but I'll give a brief explanation here: Firstly, a triangulation is made from the points and colors are chosen for each triangle. Then, the variance between the triangles and

Thanks! One main difference from Primitive is that Primitive's shapes can overlap, while Triangula generates a triangulation.

I'm a bit unsure of what you mean, but the genetic algorithm is used to find an optimal set of points, and then a Delaunay triangulation is created from those points.

Wails v1 (which this project uses) uses Webview for rendering it's frontend. You can read more about how Wails works here: https://wails.app/about/concepts/ Also because I'm pretty sure you're goin
