◆ BM_mesh_elem_index_validate()

void BM_mesh_elem_index_validate ( BMesh * bm,
const char * location,
const char * func,
const char * msg_a,
const char * msg_b )

Array checking/setting macros.

Currently vert/edge/loop/face index data is being abused, in a few areas of the code.

To avoid correcting them afterwards, set 'bm->elem_index_dirty' however its possible this flag is set incorrectly which could crash blender.

Functions that calls this function may depend on dirty indices on being set.

This is read-only, so it can be used for assertions that don't impact behavior.

◆ BM_mesh_remap()

Remaps the vertices, edges and/or faces of the bmesh as indicated by vert/edge/face_idx arrays (xxx_idx[org_index] = new_index).

A NULL array means no changes.

Note
  • Does not mess with indices, just sets elem_index_dirty flag.
  • For verts/edges/faces only (as loops must remain "ordered" and "aligned" on a per-face basis...).
Warning
Be careful if you keep pointers to affected BM elements, or arrays, when using this func!
