LoopStructural: Loop3D Implicit Geological Modelling

3D model of Hamersley created using loopstructuralPyPI versionGitHub licenseDocumentation loop3d.github.io/LoopStructural/

Overview

LoopStructural is an opensource Python library for 3D geological modelling. The library has been built in the scope of the Loop project (Loop3d.org). LoopStructural can:

  • Model fault networks integrating fault kinematics and overprinting relationships
  • Model folds using structural elements (fold axis, fold axial surface) for multiple fold events
  • Use different implicit interpolation algorithms (Finite Difference, Piecewiese Linear, RBF)
  • Export models to vtk, geoh5, omf, gocad, csv, obj formats
  • Visualise models in an interactive python environment.

Installation

Google colab

LoopStructural can be used inside a google colab notebook, however interactive visualisation using kitware trame does not work. Only static plots can be displayed.

Pip

pip install loopstructural

Optional dependencies are:

  • loopstructuralvisualisation (wrapper for pyvista to interface with loopstructural objects)
  • pyvista (3D visualisation)
  • geoh5py (export to .geoh5 format)
  • mira-omf (export to .omf format to load in Leapfrog)
  • pyevtk
  • dill (serialize loop models to a pickle file)
  • tqdm (progress bars)
  • loopsolver (experimental solver for admm inequality constraints)

You can install all of the optional dependencies using: pip install loopstructural[all]

conda

conda install -c conda-forge -c loop3d loopstructural

LoopStructural: Loop3D Implicit Geological Modelling
3D model of Hamersley created using loopstructuralPyPI versionGitHub licenseDocumentation loop3d.github.io/LoopStructural/
Overview
LoopStructural is an opensource Python library for 3D geological modelling. The library has been built in the scope of the Loop project (Loop3d.org). LoopStructural can:
  • Model fault networks integrating fault kinematics and overprinting relationships
  • Model folds using structural elements (fold axis, fold axial surface) for multiple fold events
  • Use different implicit interpolation algorithms (Finite Difference, Piecewiese Linear, RBF)
  • Export models to vtk, geoh5, omf, gocad, csv, obj formats
  • Visualise models in an interactive python environment.
Installation
Google colab
LoopStructural can be used inside a google colab notebook, however interactive visualisation using kitware trame does not work. Only static plots can be displayed.
Pip
pip install loopstructural
Optional dependencies are:
  • loopstructuralvisualisation (wrapper for pyvista to interface with loopstructural objects)
  • pyvista (3D visualisation)
  • geoh5py (export to .geoh5 format)
  • mira-omf (export to .omf format to load in Leapfrog)
  • pyevtk
  • dill (serialize loop models to a pickle file)
  • tqdm (progress bars)
  • loopsolver (experimental solver for admm inequality constraints)
You can install all of the optional dependencies using:
pip install loopstructural[all]
conda
conda install -c conda-forge -c loop3d loopstructural
to install the working 3D visualisation environment
conda install -c conda-forge -c loop3d loopstructural loopstructuralvisualisation pyvista trame trame-vtk trame-vuetify
