PZero
PZero is a Python open-source 3D geological modelling application, leveraging various libraries, with a user-friendly graphical user interface allowing to perform most standard geomodelling data management and analysis tasks, explicit surface interpolation, and advanced implicit interpolation.
To build PZero we use several open-source libraries. VTK provides classes for all 3D objects, in addition to 3D visualization and basic analysis and modelling tools. The PZero graphical user interface is built with Qt. All objects in a PZero project and their metadata are collected and managed in pandas dataframes. We use a VTK-Numpy interface that allows performing most mathematical processing with simple NumPy syntax, while 2D plotting is performed with Matplotlib. PyVista and vedo provide simplified access to VTK visualization and I/O tools. Various 2D graphical and topological editing tools in PZero are based on Shapely, while GeoPandas, Rasterio, Xarray, laspy, and EzDxf provide I/O tools for GIS, point cloud, and CAD data. LoopStructural provides three different implicit surface interpolation algorithms. mplstereonet provides stereoplots for orientation analysis.
Developers of these libraries are warmly thanked!
The PZero project started in spring 2020 thanks to a research project funded by Pro Iter Tunnelling & Geotechnical Department and lead by Andrea Bistacchi and Luca Soldo. PZero is now supported by the Geosciences IR project lead by ISPRA - Servizio Geologico d'Italia and funded by PNRR.
The PZero developers are (or have been): * Andrea Bistacchi (since the beginning) * Gloria Arienti (December 2021 - January 2023) * Gabriele Benedetti (since January 2022) * Alessandro Frigeri (January 2022 - April 2022) * Tommaso Comelli (April 2023 - July 2023) * Luca Penasa (since April 2023) * Waqas Hussain (since November 2023) * Riccardo Monti (since November 2023) * Ivano Brunet (since March 2024) * Francesco Visentin (since March 2024)

The name of PZero was inspired by the zeroth element in Emile Argand's 3D model of the Pennine Alps nappe stack - possibly the first quantitative 3D geological model in the history of geological sciences (Argand E., 1911. Les Nappes de recouvrement des Alpes pennines et leurs prolongements structuraux. Mat. Carte géol. Suisse, 31, 1-26), and by Python.
