Scientific 3D Printing with GRASS GIS (FOSSGIS 2014)

  1. 1. Scientific 3D Printing with GRASS GIS A Work in Progress Report Dr. Peter Löwe FOSSGIS 2014 2014-03-20
  2. 2. 2 In a nutshell • Interfacing GRASS GIS with 3D print workflows can be done with the current GRASS modules. • Prediction: Easy to use GRASS extensions for 3D printing will come soon. • Scientific 3D prints extend „flat“ 2D science communication • Decelerated haptic data access (no-display-needed) • But there‘s more to it…
  3. 3. 3 Communicating scientific findings The challenge: • Picturing scientific data in one’s mind • Communicating this vision to someone else The need: A tangible representation of scientific results. 1492 Today Future ?

  14. 14. 14 The Scientific Library perspective – Why bother ? • This is part of an emerging trend affecting (Geo-) Science and Research, Libraries and the FOSS Communities. • Identification, citation and preservation of scientific content needed. • A tide of „born digital“ specimen, like 3D prints, is coming. • Persistant identifiers are being introduced for scientific articles, data and software – and 3D prints, e.g: Digital Object Identifiers (DOI).

  28. 28. 28 Wanted: 3D print workflow trailblazers ! • Volume generalisation with r3.x-modules requires currently these skills: • Science Interpreter/Communicator: „What message to convey ?“ • Technical/Software: create workflows in r3.mapcalc, script these • Admin/Pioneer: be able to install patches for GRASS7 due to bugs (volume-related), help improve code maturity
  29. 29. 29 Example: Thematic generalisation with r3.mapcalc • Task: Separation of geologic volumes along complex faults („cutting pane“) • Requirement: Volume hulls must be continuous (no holes). • Solution: „Growing“ of fault lines into cutting panes with r3.mapcalc.
