SurfaceMeshIO

OVITO extension to read/write surface meshes with all attached properties from/to a compressed numpy file.

The configuration of the visual element is not exported.

Example

The surface mesh created in examples/example_01.ovito can be exported using the export file dialog selecting the "Surface mesh file writer" format.

The resulting .npz file matches examples/example_01.npz. This file can be opened in OVITO Pro GUI. This reconstructs the surface mesh with all its properties.

Both import and export are also available from Python:

from ovito.io import import_file, export_file

# import npz file
pipeline = import_file("examples/example_01.npz")

from SurfaceMeshIO import SurfaceMeshFileWriter

# export npz file
export_file(data, "examples/example_01.npz", format=SurfaceMeshFileWriter, key=data.surfaces["surface"])

Installation

• From the OVITO Pro using the extensions GUI

• OVITO Pro integrated Python interpreter:

  ovitos -m pip install --user git+https://github.com/ovito-org/SurfaceMeshIO
  

  The --user option is recommended and installs the package in the user's site directory.

• Other Python interpreters or Conda environments:

  pip install git+https://github.com/ovito-org/SurfaceMeshIO
