If you need advanced Computational Geometry support for your visualization and analysis, then we have you covered!


Follow these steps to get up and running with an OOD remote desktop and a custom compiled paraview container providing cgal vespa.


# pull the container
apptainer pull docker://ghcr.io/devinbayly/cgal_vespa:latest

When this is complete you must run the container and start paraview

apptainer exec cgal_vespa_latest.sif /opt/paraview_build/bin/paraview

When paraview starts you need to import the Vespa paraview plugin which will be at this system path

/usr/local/lib/paraview-5.11/plugins/VESPAPlugin/VESPAPlugin.so


Then the following filters can help for estimating volumes contained within areas of interest in imaging data

  • threshold
  • extract surface
  • tetrahedralize
  • Alpha Wrap (CGAL Vespa)
  • Connectivity
  • Compute Connected Surface Properties

Refer to the screen recording shared here for other details, as well as the demo_state.pvsm which you can just load in the custom paraview container to get started.
