Since R2022b

## Syntax

``addFaces(mesh,faces)``
``addFaces(___,Name=Value)``

## Description

example

````addFaces(mesh,faces)` adds the specified faces to the `surfaceMesh` object, `mesh`.```
````addFaces(___,Name=Value)` specifies options using one or more name-value arguments in addition to the previous syntax. For example, ```addFaces(mesh,faces,FaceNormals=[1 2 0; 1 1 1; 0 2 2; 4 3 0; 2 1 2; 5 5 0])``` specifies the face normals for the surface mesh.```

## Examples

collapse all

Define mesh vertices for a surface mesh.

```vertices = [1 -1 1; 1 1 1; -1 1 1; -1 -1 1; ... 1 -1 -1; 1 1 -1; -1 1 -1; -1 -1 -1];```

Define the mesh faces using the vertices.

```faces = [6 2 1; 1 5 6; 8 4 3; 3 7 8; 6 7 3; 3 2 6; ... 5 1 4; 4 8 5; 4 1 2; 2 3 4; 7 6 5; 5 8 7];```

Create and display the surface mesh.

```mesh = surfaceMesh(vertices,faces); surfaceMeshShow(mesh,Title="Original Mesh")``` Add a new vertex to the surface mesh.

`addVertices(mesh,[0 0 2])`

Add new faces to surface mesh and display the updated mesh.

```faces = [1 4 9; 2 3 9]; addFaces(mesh,faces); surfaceMeshShow(mesh,Title="Modified Mesh")``` ## Input Arguments

collapse all

Surface mesh, specified as a `surfaceMesh` object.

Mesh triangular faces, specified as an N-by-3 matrix. Each row of the array is in the form ```[V1 V2 V3]```, specifying the vertex IDs of the vertices which define the triangular face. N is the total number of faces to add to the mesh.

Data Types: `single` | `double`

### Name-Value Arguments

Specify optional pairs of arguments as `Name1=Value1,...,NameN=ValueN`, where `Name` is the argument name and `Value` is the corresponding value. Name-value arguments must appear after other arguments, but the order of the pairs does not matter.

Example: ```addFaces(mesh,faces,FaceNormals=[1 2 0; 1 1 1; 0 2 2; 4 3 0; 2 1 2; 5 5 0])```

Normal vectors for the mesh faces, specified as an N-by-3 matrix. Each row of the matrix of in the form `[x y z]`, specifying the normal for a face. N is the total number of faces to add to the mesh.

Data Types: `single` | `double`

Color values for the mesh faces, specified as an N-by-3 matrix. Each row of the matrix is of the form `[R G B]`, specifying the color value for a face. Each value must be in the range `[0,1]`. N is the total number of faces to add to the mesh.

Data Types: `single` | `double`
