4 points · Open discussionI'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 not production ready but should work for almost all cases.
Any feedback for both projects is appreciated!

1 points · Open discussionTriangula 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.

In Show HN: I built a tool to generate triangulated art from imagesThis is great, especially the SF example as it reminds me of Brian Lotti's paintings [1]
A common technique for painters is to establish areas of colour in the scene that are similar even though the eye perceives them differently. For example the shade beneath a tree - while complex in reality - can be easily represented with a single stroke of darker colour.
Zooming in to the SF example [2] you begin to see how this scene could be painted, which makes me think this tool could be a useful guide in painting tutorials.

In Show HN: I built a tool to generate triangulated art from imagesThanks! 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.

In Show HN: I built a tool to generate triangulated art from imagesAh, I must've misread the wiki. I thought it meant you used genetic algorithm for triangulation instead of point selection. What's your criteria for calculating the fitness for a candidate set of points?
