Structural geology modelling example prototype code in Netlogo using Spatial Agents.
Developed by Eric A. de deKemp Geological Survey of Canada Ottawa, Ontario, Canada
March 1, 2021
This repository is developed to help distribute GeoSwarm Netlogo codes for those wanting to demo, test, enhance and explore the potential uses of Spatial Agent Based approaches to the modelling of sparse structural geology data for more complex features.
Several movie clips have been included in the docs folder in MP4 file format for that purpose. These are also viewable in the embedded gifs of the power point presentation in GeoSwarm/Docs/deKemp_Agents_2019.pptx, also in the Docs folder, made at the International Association of Mathematical Geoscientists annual meeting in Penn State, Pensilvania, USA in August 2019.
The NetLogo program files used in this project have been upgraded to Netlogo 3D v. 6.0.4. Older codes such as Wave.nlogo (1996) have been included for reference and demonstration purposes. Below is a list of codes and the current version level located in GeoSwarm/Main/.

Many thanks to Uri Wilensky, NetLogo team of developers and contributors who continue to enhance applications and extend the functionality of NetLogo with extensions to 3D, GIS, numerical functionality and other shared codes. Several examples such as wave and flocking codes have been the starting codes for this work presented here. Many thanks to Sarah D'Ettorre (2013) who initiated the first agent meshing codes now incorporated into Mesh_IAMG.NetLogo3d. Thanks also to Doron Nussbaum, Carleton University, School of Computer Science who provided supervision of Sarah D'Ettorre while working on her MSc. Thanks to Mike Hiller and Boyan Brodaric (GSC), for valuable feedback. Early consultation on AI methods from Éric Beaudry, (Université du Québec a Montréal), Khalid Djado and Mathieu Bouyrie (Kinna Technologies) is appreciated. Thanks to all the LOOP 3D team https://loop3d.org/ especially Mark Jessell and Laurent Ailleres for their patience and support of the project. Thanks to RING https://www.ring-team.org/ for academic support for use of Gocad/SKUA software and to Guilaume Caumon of who provided critical feedback for the research.
Note for the Wave code see http://ccl.northwestern.edu/netlogo/models/WaveMachine3D Copyright 1996 Uri Wilensky, all rights reserved, and for other codes such as the flocking codes used in Dip_Swarm see the Netlogo commons at http://ccl.northwestern.edu/netlogo/. Center for Connected Learning and Computer-Based Modeling, Northwestern University, Evanston, IL. for terms of use. The Wave code and other code snippets have been reproduced here for accademic demo purposes with the understanding that these are to be used for the sole purpose of enhancing the community practice and use of spatial agents for scientific modelling.
Note also that many comments have been left in the code which will hopefully help the user to understand specific functions as well as potential future direction for the code. There may be unfinished or commented out proceedures that reduce functionality through the interface. These were left as bread crumbs for potential future development paths should an enthusiastic individual continue the exciting path awaiting in agent-based structural geology development.
