Voronoi Analysis - edge length threshold

In Ovito, there is the excellent option of using "Edge length threshold" when performing Voronoi analysis. However, I am trying to use voro++ code (to get information on the vertices of Voronoi polyhedra) and couldn't find this option. Can someone help me with this?

 

PS: Sorry, this is not technically  a Ovito-related question. Hoping Alex or someone familiar with voro++ can help.

 

Thanks, Ajay

Hi Ajay,

this feature is only part of OVITO not voro++, here's the corresponding code part of the Voronoi analysis modifier: https://gitlab.com/stuko/ovito/blob/master/src%2Fovito%2Fparticles%2Fmodifier%2Fanalysis%2Fvoronoi%2FVoronoiAnalysisModifier.cpp

To avoid having to implement that yourself, I'm wondering if one could maybe output all edges using voro++ and then filter those that are larger than your specified threshold in post-processing. What do you think?

Hi Constanze,

Thanks for the info. Was hoping to use a simple command line option to execute this in voro++ but I will work on the lines of your suggestion.

Thanks again, Ajay
