Introduction

Parsli is a VTK+trame based viewer for fault system kinematics that enables fast exploration and export of time animation.

Getting started

First you should setup a virtual environment for this Python Application. You can use conda, uv or anything else for managing your Python runtime. For the following commands, we will be using uv with Python 3.10.

uv venv -p 3.10
source .venv/bin/activate
uv pip install parsli

Once your environment is loaded, you can start the viewer by running the following command:

# use remote rendering
python -m parsli.viewer --data ./data/model_0000000881_multi.hdf5

# use wasm for local rendering
python -m parsli.viewer --data ./data/model_0000000881_multi.hdf5 --wasm

# use shorthand executable
parsli --data ./data/model_0000000881_multi.hdf5

Keyboard binding

• left/right/up/down arrow: Rotate camera by 1°. Modifier x5 <alt>.
• -/+: Zoom out / Zoom in.
• r: Reset camera to data
• t: Snap view up to true vertical.
• f: Focus to the mesh bounds
• home: Go to first timestep
• end: Go to last timestep
• space: Toggle play/stop animation
• </>: Previous/Next timestep. Modifiers x10 alt or shift, x100 alt+shift.

Once you've exported a couple of time animations, you can play them back using the player. Just add all the paths you want to see after the --data argument.

parsli-player --data ./export/dip_slip ./export/strike_slip ./export/dip_slip_formula ./export/strike_slip_formula

Keyboard binding

• right arrow: Go to next timestep
• left arrow: Go to previous timestep
• home: Go to first timestep
• end: Go to last timestep
• space: Toggle play/stop animation

Development setup

We assume your virtual environment is activated

uv pip install -e ".[dev]"
pre-commit install

This will automatically format and some static checking on the code at commit time, but you can also run it by hand using the following command line.

pre-commit run --all-files

Nox can also be used for running tests or linting the code.

# run everything
nox

# run just the linting
nox -s lint

Commit message convention

Semantic release rely on conventional commits to generate new releases and changelog.
