       Say, rust friends, anyone know of a good library to do mesh triangulation/tetrahedralization and refinement? The inputs would be primarily 2D outlines, sometimes with holes, all fully manifold, and potentially non-sparse N*M matrices representing  present/non-present points on a plane. Ideally supporting mesh refinement and tuningIs the best option to just link with gmsh and figure things out from there?I also need to figure out VTK/HDF5 seralization too, bweh.

       @lethalbit oof that's going to be quite complicated (given that those involved with Topola haven't something nice either). you should probably expect all solutions to be suboptimal.A few basic things work (e.g. https://docs.rs/spade, https://docs.rs/i_overlay ), but the more involved stuff isn't in a too good shape.

       @ada yeah some of them, for 2D anyway,I still eventually need full 3D tetrahedralization (or maybe hexahedralization).Generally the plan is to take the input 2D polygons and "extrude" them into a 3D to then mesh after modification, and due to the nature, they do need to be meshed down with some finer-grained meshing along boundaries, so it can't really be just a standard convex hull.But anynyan! thanks for the links!
