mesh_edge_set
ABSTRACT
Generates a set of edges from the provided mesh-tree, each edge represented as a pair of vertices.
PARAMETERS
| mesh | Specifies to take every single edge of every single mesh in the mesh-tree |
| root | Specifies the container that holds the meshes for the operation. |
| tag_predicate(tag) | Determines whether edges from a mesh should be included based on the provided tag. |
RETURN
A set of edges extracted from the selected meshes, where each edge is represented by a pair of vertex indices. In particular, a vector of vector of 3-vector is return, where each subvector is of length 2 and represents an edge by its starting and ending vertices. The edges should be treated as undirected, and there may be duplicates.
DECLARATION
