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. phoenix trinity stainless steel gripWebThe 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).

WebThe speed is comparable with Mapbox's C++ version of earcut, earcut.hpp, except for input of very small polygons where the speed is much slower. See the benchmarking section for more detail. If you want to get correct triangulation even on very bad data with lots of self-intersections and earcutr is not precise enough, take a look at libtess.js . WebTo install this package run one of the following: conda install -c conda-forge mapbox_earcut. Description.
