writeSurfaceMesh

Write 3-D surface mesh into STL or PLY file

Since R2022b

Syntax

writeSurfaceMesh(mesh,fileName)

writeSurfaceMesh(mesh,fileName,Encoding=enc)

Description

writeSurfaceMesh(mesh,fileName) writes the surface mesh mesh into an STL or PLY file with the specified filename.

writeSurfaceMesh(mesh,fileName,Encoding=enc) additionally specifies the encoding type as "ascii" or "binary".

Examples

Write Surface Mesh Data into STL and PLY File

Define mesh vertices and faces for a surface mesh.

vertices = [0 0 0; 0 0 1; 0 1 1; 0 0 2; 1 0.5 1];
faces = [1 2 3; 2 3 4; 2 3 5];

Create and display the surface mesh.

mesh = surfaceMesh(vertices,faces);
surfaceMeshShow(mesh)

Write the surface mesh data into an STL file.

writeSurfaceMesh(mesh,"ManifoldMesh.stl")

Write the surface mesh data into a PLY file.

writeSurfaceMesh(mesh,"ManifoldMesh.ply")

Input Arguments

mesh — Surface mesh to write

surfaceMesh object

Surface mesh to write, specified as a surfaceMesh object.

fileName — Filename to write surface mesh data to

character vector | string scalar

Filename to write surface mesh data to, specified as a character vector or string scalar. You must specify the .stl or .ply extension along with the filename. If a file of specified name already exists, it must have write permissions.

enc — Encoding type

"ascii" (default) | "binary"

Encoding type in which to write surface mesh data to the file, specified as "ascii" or "binary".

Data Types: char | string

Limitations

You cannot write these attributes into an STL file.

• Vertex normals

• Vertex colors

• Face colors

You cannot write face normals and face colors into a PLY file.
