Earcut algorithm

WebThe mesh needs to be a constrained "delaunay triangulation". In the image below I showed (on the left) the set of points I start from (blue and red dots). I also know the connections between these points (the outline in black). The mesh needs to look like the example on the right (including the edges in grey that form outside and inner triangles).

WebApr 4, 2014 · Sweepline Delaunay algoritm can be O (n*log (n)) not O (log (n)). With small number of points an implementation with worst case O (n^2) can be faster than O (n*log (n)) implementation. One reason can be that the O (n*log (n)) algorithm might have to use a hierarchical data structure. Constantly adding and removing points and balancing a tree ... WebMay 28, 2024 · 5. You can create a path using Font.getPath. Path consists of move-to, line-to, curve-to, quad-to and close instructions, accessed via path.commands. You will need to convert bezier curve instructions into small segments first, of course. Once you have a set of closed paths, you need to determine which ones are holes.
