  • Incremental Randomized Delaunay Triangluation

    Back in 2013, while I was doing my bachelor studies, I somehow talked my way into the university office letting me take a masters-level course on computational geometry.

You can see explanation (in Lithuanian), diagrams, and code on the link I've shared.
