Is Delaunay algoritm faster than Ear Clipping? I ask, because I understand, that if n time is significantly bigger for Delaunay, it may be slower after all. northern aroostook registry of deedsWebThe aim of this project is to create a JS triangulation library that is fast enough for real-time triangulation in the browser, sacrificing triangulation quality for raw speed and simplicity, while being robust enough to handle most practical datasets without crashing or producing garbage.
