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). WebThe npm package earcut receives a total of 923,687 downloads a week. As such, we scored earcut popularity level to be Popular. ... Changed the algorithm to avoid filtering colinear/duplicate vertices unless it can't triangulate the polygon otherwise. Improves performance on simpler shapes and fixes some 3D use cases.

The triangulation requires an Earcut script. Whilst an Earcut script is pre-loaded in the Playground you will have to add a reference to such a script in your own projects.
WebExtruded Non Regular Polygon. ExtrudePolygon adds a depth option to CreatePolygon. The extrusion is carried out down the vertical y axis from the polygon shape in the horizontal xz plane. Like CreatePolygon it requires an Earcut script. Since it can be concave it requires a procedure to fill the polygon with triangles and an Earcut method is used.
