I have a mesh which I remeshed to a more coarse mesh. I then load this into a module named trimesh and I extract the vertices and faces. I then use MeshPy for tetrahedralizing: tetmesh_info = MeshInfo() tetmesh_info.set_points(stl_verts) tetmesh_info.set_facets(stl_faces) options = mp.Options('pq') tetmesh = mp.build(tetmesh_info, options, max_volume=volume_constraint ) tetmesh.write_vtk('Output\\Meshes\\{}_tet.vtk'.format(name)) The resultant mesh's surface is much finer than the inputted mesh, in fact it looks to have the same coarseness as the mesh before it was remeshed Is this caused by TetGen do you think? Is there a setting I can change for this? Or is it more likely that the verts and faces are somehow retained by the remesh operation in the STL file and TetGen tetrahedralizing my original mesh? Thanks for any insight you can give me, Sam
