script/extract_edges.py script¶
Extract outline edges of a given mesh and save them into ‘<original path>/edge_<original mesh file name>.vtk’ or into a user defined output file. The outline edge is an edge for which norm(nvec1 - nvec2) < eps, where nvec1 and nvec2 are the normal vectors of the incident facets.
- extract_edges.extract_edges(mesh, eps=1e-16)[source]¶
Extract outline edges of a given mesh. The outline edge is an edge for which norm(nvec_1 - nvec_2) < eps, where nvec_1 and nvec_2 are the normal vectors of the incident facets.
- Parameters
- meshMesh
The 3D or 2D mesh.
- epsfloat
The tolerance parameter of the outline edge searching algorithm.
- Returns
- mesh_outtuple
The data of the outline mesh, Mesh.from_data() format, i.e. (coors, ngroups, ed_conns, mat_ids, descs).
