Goal.
I would like to tell you a bit about my favorite theorems, ideas or concepts in mathematics and why I like them so much.
This time.
What is...Fortune’s algorithm? Or: Parabolas and distance.
Disclaimer.
Nobody is perfect, and I might have said something silly. If there is any doubt, then please check the references.

I'm preparing for the exam on Discrete Math. The explanation of the general idea was clear. Thank you from Russia!

A real-world application of the algorithm? Absolutely fabulous! Thanks for sharing. Let us know whether this works out. Fingers crossed.

@drackomalfoid9276 I decided to use Bowyer-watson algorithm to create a Delaunay triangulation and then create the Voronoi diagram from that. It was way easier to implement imo.

Hmm, I tried to imagine that for a while. Not sure what is happening 🤔😅
