OVITO Pro includes a Python code generation function, which can turn any data pipeline
created with the graphical user interface into a corresponding sequence of Python script statements,
which may subsequently be executed outside of OVITO to automate data post-processing or visualization
workflows. While you interactively adjust the parameters of modifiers, the code generation function
produces corresponding script statements for OVITO’s Python programming interface.
The generated source code may be saved to disk, further customized if desired,
and then run using the embedded Python script interpreter ovitos or any regular Python interpreter after installing the
ovito Python module (see downloads).
The Python code generator is invoked by selectingfrom the menu. The code generator window displays the dynamically generated source code, which gets updated in realtime while you make changes to the data pipeline or a modifier’s settings.
You can activate the option Visualization code to let OVITO additionally generate code statements that set up the virtual camera, render settings, and the visual appearance of the dataset exactly as you prescribed it in the graphical user interface. This option is useful if you are going to use the generated Python script for automating image and animation rendering tasks.
The code generator can generate Python statements for the following aspects of the visualization scene:
Data file import (all arguments of the
Viewport camera setup
Rendering engine configuration
Image/animation render settings
The following aspects are not covered by the code generator yet:
Direct modifications you make to imported data objects in the GUI, e.g. the colors and radii of particle types
Data export to an output file
Key-frame based parameter animations
Thus, you have may have to amend the generated script with corresponding code statements yourself to
take care of these things. See the sections Data export and
ParticleType.radius in the OVITO Python API documentation on how to do that.
