WebThe way PolygonMeshBuilder works is to construct and return the triangulation of the polygon and then create the mesh from this triangulation using its build method. 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.
