  • Incremental Randomized Delaunay Triangluation (Other amazing things)

    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. This was my final project for that course. I implemented incremental randomized Delaunay triangulation in optimal complexity, which was a bit tricky. You can see explanation (in Lithuanian), diagrams, and code on the link I've shared.
