HighlightMesh[mr,{cellspec1,cellspec2,…}]

highlights the cells specified by cellspeci in the mesh region mr.

HighlightMesh[mr,{…,wj[cellspecj],…}]

highlights using the symbolic wrappers wj.

Details and Options

  • The cell specification follows the standard form {dim,indexes} and is specifically described in the reference pages for MeshRegion and BoundaryMeshRegion.
  • HighlightMesh[mr,{ms1,ms2,…}] returns a new mesh region with the cells specified by msi highlighted.
  • The following wrappers can be used:
  • Labeled[cell,…]display the element with labeling
    Style[cell,spec]show the element using the specified styles
  • HighlightMesh takes the same options as MeshRegion and BoundaryMeshRegion.
  • Styles and other specifications for cells are taken to apply to the highlighted elements celli.

Basic Examples  (3)

Highlight points of a mesh:

Wolfram Language code: ℛ = BoundaryMeshRegion[{{0, 0}, {1, 0}, {0, 1}}, Line[{1, 2, 3, 1}]];
Wolfram Language code: HighlightMesh[ℛ, 0]

Highlight a face of a mesh:

Wolfram Language code: ℛ = MeshRegion[{{0, 0, 0}, {1, 0, 0}, {0, 1, 0}, {0, 0, 1}}, {Tetrahedron[{1, 2, 3, 4}]}];
Wolfram Language code: HighlightMesh[ℛ, {2, 4}]

Scope  (7)

Specification  (4)

HighlightMesh works with MeshRegion:

Wolfram Language code: ℛ = MeshRegion[{{0, 0}, {1, 0}, {1, 1}}, Polygon[{1, 2, 3}]];
Wolfram Language code: HighlightMesh[ℛ, 1]

BoundaryMeshRegion:

Wolfram Language code: ℛ = BoundaryMeshRegion[{{0, 0}, {1, 0}, {1, 1}}, Line[{1, 2, 3, 1}]];
Wolfram Language code: HighlightMesh[ℛ, 1]

HighlightMesh works on 2D regions:

Wolfram Language code: ℛ = MeshRegion[{{0, 0}, {1, 0}, {1, 1}}, Polygon[{1, 2, 3}]];
Wolfram Language code: HighlightMesh[ℛ, 1]

3D regions:

Wolfram Language code: ℛ = MeshRegion[{{0, 0, 0}, {1, 0, 0}, {0, 1, 0}, {0, 0, 1}}, {Tetrahedron[{1, 2, 3, 4}]}];
Wolfram Language code: HighlightMesh[ℛ, 1]

HighlightMesh works with points:

Wolfram Language code: ℛ = MeshRegion[{{0, 0, 0}, {1, 0, 0}, {0, 1, 0}, {0, 0, 1}}, {Tetrahedron[{1, 2, 3, 4}]}];
Wolfram Language code: HighlightMesh[ℛ, {0, 4}]

Edges:

Wolfram Language code: HighlightMesh[ℛ, {1, 5}]

Faces:

Wolfram Language code: HighlightMesh[ℛ, {2, 4}]

Patterns:

Wolfram Language code: HighlightMesh[ℛ, {1, _ ? EvenQ}]

Highlight a specified cell:

Wolfram Language code: ℛ = MeshRegion[{{0, 0}, {1, 0}, {1, 1}}, Polygon[{1, 2, 3}]];
Wolfram Language code: HighlightMesh[ℛ, {1, 1}]

A collection of cells with the same dimension:

Wolfram Language code: HighlightMesh[ℛ, {1, {1, 2}}]

All cells with a given cell dimension:

Wolfram Language code: HighlightMesh[ℛ, 0]

A collection of cells:

Wolfram Language code: HighlightMesh[ℛ, {{0, 1}, {1, 2}}]

Multiple collections of cells:

Wolfram Language code: HighlightMesh[ℛ, {{0, {1, 2}}, {1, {2, 3}}}]

Styling and Labeling  (3)

Specify the highlighting style of a cell:

Wolfram Language code: ℛ = MeshRegion[{{0, 0}, {1, 0}, {1, 1}}, Polygon[{1, 2, 3}]];
Wolfram Language code: HighlightMesh[ℛ, Style[1, Red]]

Label cells with their indices:

Wolfram Language code: ℛ = MeshRegion[{{0, 0}, {1, 0}, {1, 1}}, Polygon[{1, 2, 3}]];
Wolfram Language code: HighlightMesh[ℛ, Labeled[0, "Index"]]

Specify an annotation for a highlighted cell:

Wolfram Language code: ℛ = MeshRegion[{{0, 0}, {1, 0}, {1, 1}}, Polygon[{1, 2, 3}]];
Wolfram Language code: HighlightMesh[ℛ, Annotation[{1, 3}, MeshCellStyle -> Pink]]

Options  (11)

MeshCellHighlight  (1)

MeshCellHighlight can be used to specify cells to highlight:

Wolfram Language code: HighlightMesh[MeshRegion[{{1, 0}, {2, 1 / 2}, {2, -1 / 2}}, {Triangle[{1, 2, 3}]}], {{1, 1}}, MeshCellHighlight -> {{1, 2} -> Red}]

MeshCellLabel  (2)

By default, MeshCellLabel of the given region is preserved:

Wolfram Language code: HighlightMesh[[image], {1, {1, 2}}]

Use MeshCellLabel->labels to specify labels of highlighted cells:

Wolfram Language code: HighlightMesh[[image], {1, {1, 2}}, MeshCellLabel -> "hello"]

MeshCellMarker  (2)

By default, MeshCellMarker of the given region is preserved:

Wolfram Language code: BoundaryMeshRegion[{{0, 0}, {1, 0}, {0, 1}}, Line[{1, 2, 3, 1}], MeshCellMarker -> {1 -> 1}, MeshCellLabel -> {1 -> "Marker"}]
Wolfram Language code: HighlightMesh[%, {1, 1}]

Use MeshCellMarkermarkers to specify labels of highlighted cells:

Wolfram Language code: BoundaryMeshRegion[{{0, 0}, {1, 0}, {0, 1}}, Line[{1, 2, 3, 1}], MeshCellMarker -> {1 -> 1}, MeshCellLabel -> {1 -> "Marker"}]
Wolfram Language code: HighlightMesh[%, {1, 1}, MeshCellMarker -> 2]

MeshCellShapeFunction  (2)

By default, MeshCellShapeFunction of the given region is preserved:

Wolfram Language code: HighlightMesh[[image], {0, {1, 2}}]

Use MeshCellShapeFunctionshapes to specify shape functions of highlighted cells:

Wolfram Language code: HighlightMesh[[image], {0, {1, 2}}, MeshCellShapeFunction -> (Disk[#, .1]&)]

MeshCellStyle  (2)

MeshCellHighlight is applied after MeshCellStyle:

Wolfram Language code: HighlightMesh[[image], {0, {1, 2}}, MeshCellStyle -> Red]

Wrap with Style to style a highlighted cell:

Wolfram Language code: HighlightMesh[[image], Style[{0, {1, 2}}, Red]]

PlotTheme  (2)

Use a theme with grid lines and a legend:

Wolfram Language code: HighlightMesh[MeshRegion[{{0, 0, 0}, {2, 0, 0}, {2, 2, 0}, {0, 2, 0}, {1, 1, 2}}, Pyramid[{1, 2, 3, 4, 5}]], 1, PlotTheme -> "Detailed"]

Use a theme to draw a wireframe:

Wolfram Language code: HighlightMesh[MeshRegion[{{0, 0, 0}, {2, 0, 0}, {2, 2, 0}, {0, 2, 0}, {1, 1, 2}}, Pyramid[{1, 2, 3, 4, 5}]], {1, 1}, PlotTheme -> "Lines"]

Properties & Relations  (4)

HighlightMesh of a MeshRegion returns a MeshRegion:

Wolfram Language code: {mr1 = DelaunayMesh[RandomReal[1, {25, 2}]], mr2 = HighlightMesh[mr1, Style[1, Brown]]}
Wolfram Language code: {MeshRegionQ[mr1], MeshRegionQ[mr2]}

HighlightMesh of a BoundaryMeshRegion returns a BoundaryMeshRegion:

Wolfram Language code: {br1 = ConvexHullMesh[RandomReal[1, {25, 2}]], br2 = HighlightMesh[br1, Style[1, Brown]]}
Wolfram Language code: {BoundaryMeshRegionQ[br1], BoundaryMeshRegionQ[br2]}

AnnotationValue can be used to set properties directly:

Wolfram Language code: mr = DelaunayMesh[RandomReal[1, {20, 2}]]; AnnotationValue[{mr, 1}, MeshCellStyle] = Brown; mr

Options can be used to set properties during the creation of a MeshRegion:

Wolfram Language code: MeshRegion[{{0, 0}, {1, 0}, {0, 1}}, Triangle[{1, 2, 3}], MeshCellLabel -> {{1, 1} -> Red, {1, 2} -> Green, {1, 3} -> Blue}]
