Basic Examples  (2)

Get the 2D cell coordinates from a MeshRegion:

Get the 3D cell coordinates from a BoundaryMeshRegion:

Scope  (4)

Get the coordinates of a 1D BoundaryMeshRegion:

A 1D MeshRegion:

Get the coordinates of a 2D BoundaryMeshRegion:

A 2D MeshRegion:

Get the coordinates of a 3D BoundaryMeshRegion:

Coordinates that are not used in primitives do not appear in MeshCoordinates:

Applications  (2)

Create a GraphicsComplex from a 2D MeshRegion:

The indices given in MeshCells correspond to MeshCoordinates:

Create the GraphicsComplex:

Extract the lines from a MeshRegion to make a wireframe mesh:

The indices given in MeshCells correspond to MeshCoordinates:

Create the wireframe mesh:

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:
