I/O Functions¶
OpenMesh provides functions that read and write meshes from and to files:
read_trimesh()
, read_polymesh()
and write_mesh()
import openmesh as om
trimesh = om.read_trimesh("bunny.ply")
polymesh = om.read_polymesh("bunny.ply")
# modify mesh ...
om.write_mesh(trimesh, "bunny.ply")
OpenMesh currently supports five file types: .obj, .off, .ply, .stl and .om
For writing .obj files there is also support for textures. You can pass the path of a texture image and optionally the suffix for the material file, default is “.mat”, but some programs, e.g. Blender expect “.mtl” as suffix
om.write_mesh(
"out.obj",
trimesh,
texture_file="moon.png",
material_file_extension=".mtl" # default is ".mat", blender needs ".mtl"
)
