Fun, interesting project

It's a super fun project, thanks for sharing! I think you might have fun with some variations too: One way you can use the Voronoi diagram to influence your point selection is…
dahart on HNThis is awesome! I worked on a very similar project a few months ago, which I also posted to HN: https://news.ycombinator.com/item?id=10418829 Looks like yours is quite a bit…

dahart on HNIn that case, you might have a bunch of fun combining your interests implementing this paper: http://www.dgp.toronto.edu/papers/ahausner_SIGGRAPH2001.pdf For rejection sampling,…

Triangulation is slow for many points
From 2 comments
Didn't think about that, good idea as a small extension! But I don't think, a video codec would work. Or maybe just with very few points/triangles. Depending on the…
EllipticCurve on HNI'm startled at your triangulation time. I last did serious work with Delauney triangulation in 1998 or so, and was triangulating ~1000000 points in a few of hours (on a machine…

Add screenshots to the README
From 1 comment
Adding some screenshots examples to the README would be good. There's a bunch here for those who didn't dig through the repo (many are at huge resolutions for those on mobile 10k…

Interpolated vertex colors instead of flat triangle colors
From 2 comments
I've played with this kind of stuff in the past, it's a lot of fun. Have you tried shading the triangles so each is colored as the interpolation of the color at the vertices?…
pacaro on HNVery cool! Is it possible to modify the algorithm to use vertex color instead of triangle color? It is possible to do interesting stuff like Homeworld 2 backgrounds.…

Very cool! In case C++ is your jam, ten years or so ago I adapted Steven Fortunes highly efficient sweep line algorithm to C++. Some info here -…
