MeshCoordinates
MeshCoordinates[mreg]
gives a list of coordinates in the mesh region mreg.
Details
- MeshCoordinates gives a list of coordinates {p1,p2,…}.
- The mesh region mreg can be either MeshRegion or BoundaryMeshRegion.
- The integer indexes returned by MeshCells refer to coordinates in the list {p1,p2,…}.

Properties & Relations (2)
The number of coordinate points is given by MeshCellCount[mreg,0]:
The indices in MeshCells refer to the MeshCoordinates:
Possible Issues (1)
When a coordinate in MeshRegion is unused, it does not appear in MeshCoordinates:
The cell indices still refer to MeshCoordinates, not the input coordinates:
